  • Java error - not a statement, what does this mean?

    - by user2898828
    I am trying to get my code to create the new constructor objects which I require to create a mobile phone object. I have tried naming the constuctor fields to create the object. when I compile my code on this line this.Mobile samsungPhone = new Mobile("Samsung", 1, 2, "verizon", 3 "GPS"); I get this error: not a statement, what does this mean?? UPDATED CODE! my code: /** * to write a simple java class Mobile that models a mobile phone. * * @author (Lewis Burte-Clarke) * @version (14/10/13) */ public class Mobile { // type of phone private String phonetype; // size of screen in inches private int screensize; // menory card capacity private int memorycardcapacity; // name of present service provider private String serviceprovider; // type of contract with service provider private int typeofcontract; // camera resolution in megapixels private int cameraresolution; // the percentage of charge left on the phone private int checkcharge; // wether the phone has GPS or not private String GPS; // instance variables - replace the example below with your own private int x; // The constructor method public Mobile(String mobilephonetype, int mobilescreensize, int mobilememorycardcapacity,int mobilecameraresolution,String mobileGPS, String newserviceprovider) { this.phonetype = mobilephonetype; this.screensize = mobilescreensize; this.memorycardcapacity = mobilememorycardcapacity; this.cameraresolution = mobilecameraresolution; this.GPS = mobileGPS; this.serviceprovider = newserviceprovider; this.typeofcontract = 12; this.checkcharge = checkcharge; // you do not use this ones during instantiation,you can remove them if you do not need or assign them some default values Mobile samsungPhone = new Mobile("Samsung", 1, 2, "verizon", 3, "GPS"); 1024 = screen size; 2 = memory card capacity; 3=resolution; GPS = gps; "verizon"=service provider; typeofcontract = 12; checkcharge = checkcharge; } } // A method to display the state of the object to the screen public void displayMobileDetails() { System.out.println("phonetype: " + phonetype); System.out.println("screensize: " + screensize); System.out.println("memorycardcapacity: " + memorycardcapacity); System.out.println("cameraresolution: " + cameraresolution); System.out.println("GPS: " + GPS); System.out.println("serviceprovider: " + serviceprovider); System.out.println("typeofcontract: " + typeofcontract); } } class mymobile { public static void) { Mobile Samsung = new Mobile("Samsung", 1, 2, "verizon", 3, "GPS"); Mobile Blackberry = new Mobile("Blackberry", "3.", "4","8", "GPS"); Samsung.displayMobileDetails(); Blackberry.displayMobileDetails(); } } any answers and replies would be greatly appreciated!

  • Android HTTP get methods

    - by Nick
    I have written a number of applications for blackberry and am just starting in Android. It seems to me that android has a lot more built in functions. I am starting by recreating some of my BB apps on Android and on one I take a few xml sites and parse them out. On blackberry I implemented this by creating a class that extended a thread. I would construct a new instance of this class with the parameters of my http request and it would call a function back in my main class, sending it the results. I am tempted to reuse my code, but am curious if android has something better built in. I have been looking at the handler class as well as possible using a service. Bascially, I would like to start a new thread that will return a document of a specific url. Thanks!

  • Welcome to BlogEngine.NET 2.9 using Microsoft SQL Server

    If you see this post it means that BlogEngine.NET 2.9 is running and the hard part of creating your own blog is done. There is only a few things left to do. Write Permissions To be able to log in to the blog and writing posts, you need to enable write permissions on the App_Data folder. If you’re blog is hosted at a hosting provider, you can either log into your account’s admin page or call the support. You need write permissions on the App_Data folder because all posts, comments, and blog attachments are saved as XML files and placed in the App_Data folder.  If you wish to use a database to to store your blog data, we still encourage you to enable this write access for an images you may wish to store for your blog posts.  If you are interested in using Microsoft SQL Server, MySQL, SQL CE, or other databases, please see the BlogEngine wiki to get started. Security When you've got write permissions to the App_Data folder, you need to change the username and password. Find the sign-in link located either at the bottom or top of the page depending on your current theme and click it. Now enter "admin" in both the username and password fields and click the button. You will now see an admin menu appear. It has a link to the "Users" admin page. From there you can change the username and password.  Passwords are hashed by default so if you lose your password, please see the BlogEngine wiki for information on recovery. Configuration and Profile Now that you have your blog secured, take a look through the settings and give your new blog a title.  BlogEngine.NET 2.9 is set up to take full advantage of of many semantic formats and technologies such as FOAF, SIOC and APML. It means that the content stored in your BlogEngine.NET installation will be fully portable and auto-discoverable.  Be sure to fill in your author profile to take better advantage of this. Themes, Widgets & Extensions One last thing to consider is customizing the look of your blog.  We have a few themes available right out of the box including two fully setup to use our new widget framework.  The widget framework allows drop and drag placement on your side bar as well as editing and configuration right in the widget while you are logged in.  Extensions allow you to extend and customize the behaivor of your blog.  Be sure to check the BlogEngine.NET Gallery at dnbegallery.org as the go-to location for downloading widgets, themes and extensions. On the web You can find BlogEngine.NET on the official website. Here you'll find tutorials, documentation, tips and tricks and much more. The ongoing development of BlogEngine.NET can be followed at CodePlex where the daily builds will be published for anyone to download.  Again, new themes, widgets and extensions can be downloaded at the BlogEngine.NET gallery. Good luck and happy writing. The BlogEngine.NET team

  • Detect user logout / shutdown in Python / GTK under Linux

    - by Ivo Wetzel
    OK this is presumably a hard one, I've got an pyGTK application that has random crashes due to X Window errors that I can't catch/control. So I created a wrapper that restarts the app as soon as it detects a crash, now comes the problem, when the user logs out or shuts down the system, the app exits with status 1. But on some X errors it does so too. So I tried literally anything to catch the shutdown/logout, with no success, here's what I've tried: import pygtk import gtk import sys class Test(gtk.Window): def delete_event(self, widget, event, data=None): open("delete_event", "wb") def destroy_event(self, widget, data=None): open("destroy_event", "wb") def destroy_event2(self, widget, event, data=None): open("destroy_event2", "wb") def __init__(self): gtk.Window.__init__(self, gtk.WINDOW_TOPLEVEL) self.show() self.connect("delete_event", self.delete_event) self.connect("destroy", self.destroy_event) self.connect("destroy-event", self.destroy_event2) def foo(): open("add_event", "wb") def ex(): open("sys_event", "wb") from signal import * def clean(sig): f = open("sig_event", "wb") f.write(str(sig)) f.close() exit(0) for sig in (SIGABRT, SIGILL, SIGINT, SIGSEGV, SIGTERM): signal(sig, lambda *args: clean(sig)) def at(): open("at_event", "wb") import atexit atexit.register(at) f = Test() sys.exitfunc = ex gtk.quit_add(gtk.main_level(), foo) gtk.main() open("exit_event", "wb") Not one of these succeeds, is there any low level way to detect the system shutdown? Google didn't find anything related to that. I guess there must be a way, am I right? :/

  • How to mix C++ Qt objects and Qt Jambi objects

    - by Dan
    Hi, I'm trying to combine some existing Qt code written in C++ with some code written in Java using Qt Jambi, but I'm not quite sure how to do it. I'm basically trying to acieve two things: Pass a QObject from C++ to Java using JNI Pass a Qt Jambi QObject from Java to C++ It looks like I can pass the pointer directly and then wrap it in QNativePointer on the Java side, but I can't figure out how to turn a QNativePointer back into the original object, wrapped by Qt Jambi. Eg: I can pass a QWidget* as a long to Java and then create a QNativePointer in Java, but how can I then construct a QWidget out of this? QJambiObject and QObject dont seem to have a "setNativePointer" method and I'm not sure how to convert it. In C++: QWidget* widget = ... jclass cls = env->FindClass("Test"); jmethodID mid = env->GetStaticMethodID(cls, "test", "(I)V"); env->CallStaticVoidMethod(cls, mid, int(widget)); In Java: public class Test { public static void test (int ptr) { QNativePointer pointer = new QNativePointer(QNativePointer.Type.Int); pointer.setIntValue(ptr); QWidget widget = ...

  • django crispy-forms inline forms

    - by abolotnov
    I'm trying to adopt crispy-forms and bootstrap and use as much of their functionality as possible instead of inventing something over and over again. Is there a way to have inline forms functionality with crispy-forms/bootstrap like django-admin forms have? Here is an example: class NewProjectForm(forms.Form): name = forms.CharField(required=True, label=_(u'???????? ???????'), widget=forms.TextInput(attrs={'class':'input-block-level'})) group = forms.ModelChoiceField(required=False, queryset=Group.objects.all(), label=_(u'?????? ????????'), widget=forms.Select(attrs={'class':'input-block-level'})) description = forms.CharField(required=False, label=_(u'???????? ???????'), widget=forms.Textarea(attrs={'class':'input-block-level'})) class Meta: model = Project fields = ('name','description','group') def __init__(self, *args, **kwargs): self.helper = FormHelper() self.helper.form_class = 'horizontal-form' self.helper.form_action = 'submit_new_project' self.helper.layout = Layout( Field('name', css_class='input-block-level'), Field('group', css_class='input-block-level'), Field('description',css_class='input-block-level'), ) self.helper.add_input(Submit('submit',_(u'??????? ??????'))) self.helper.add_input(Submit('cancel',_(u'? ?????????'))) super(NewProjectForm, self).__init__(*args, **kwargs) it will display a decent form: How do I go about adding a form that basically represents this model: class Link(models.Model): name = models.CharField(max_length=255, blank=False, null=False, verbose_name=_(u'????????')) url = models.URLField(blank=False, null=False, verbose_name=_(u'??????')) project = models.ForeignKey('Project') So there will be a project and name/url links and way to add many, like same thing is done in django-admin where you are able to add extra 'rows' with data related to your main model. On the sreenshot below you are able to fill out data for 'Question' object and below that you are able to add data for QuestionOption objects -you are able to click the '+' icon to add as many QuestionOptions as you want. I'm not looking for a way to get the forms auto-generated from models (that's nice but not the most important) - is there a way to construct a form that will let you add 'rows' of data like django-admin does?

  • pyqt QTreeWidget setItemWidget dissapears after drag/drop

    - by mleep
    I'm trying to keep a widget put into a QTreeWidgetItem after a reparent (drag and drop) using QTreeWidget.setItemWidget() But the result, if you compile the following code - is that the widget inside the QTreeWidgetItem disappears. Any idea why? What code would fix this (repopulate the QTreeWidgetItem with the widget I guess?) from PyQt4.QtCore import * from PyQt4.QtGui import * class InlineEditor (QWidget): _MUTE = 'MUTE' def __init__ (self, parent): QWidget.__init__ (self, parent) self.setAutoFillBackground (True) lo = QHBoxLayout() lo.setSpacing(4) self._cbFoo = QComboBox() for x in ["ABC", "DEF", "GHI", "JKL"]: self._cbFoo.addItem(x) self._leBar = QLineEdit('', self) lo.addWidget (self._cbFoo, 3) lo.addSpacing (5) lo.addWidget (QLabel ( 'Bar:')) lo.addWidget (self._leBar, 3) lo.addStretch (5) self.setLayout (lo) class Form (QDialog): def __init__(self,parent=None): QDialog.__init__(self, parent) grid = QGridLayout () tree = QTreeWidget () # Here is the issue? tree.setDragDropMode(QAbstractItemView.InternalMove) tree.setColumnCount(3) for n in range (2): i = QTreeWidgetItem (tree) # create QTreeWidget the sub i i.setText (0, "first" + str (n)) # set the text of the first 0 i.setText (1, "second") for m in range (2): j = QTreeWidgetItem(i) j.setText (0, "child first" + str (m)) #b1 = QCheckBox("push me 0", tree) # this wont work w/ drag by itself either #tree.setItemWidget (tree.topLevelItem(0).child(1), 1, b1) item = InlineEditor(tree) # deal with a combination of multiple controls tree.setItemWidget(tree.topLevelItem(0).child(1), 1, item) grid.addWidget (tree) self.setLayout (grid) app = QApplication ([]) form = Form () form.show () app.exec_ ()

  • Finding duplicate rows in SQL Server

    - by xtine
    I have a SQL Server database of organizations, and there are many duplicate rows. I want to run a select statement to grab all of these and the amount of dupes, but also return the ids that are associated with each organization. A statement like: SELECT orgName, COUNT(*) AS dupes FROM organizations GROUP BY orgName HAVING (COUNT(*) > 1) Will return something like orgName | dupes ABC Corp | 7 Foo Federation | 5 Widget Company | 2 But I'd also like to grab the IDs of them. Is there any way to do this? Maybe like a orgName | dupeCount | id ABC Corp | 1 | 34 ABC Corp | 2 | 5 ... Widget Company | 1 | 10 Widget Company | 2 | 2 The reason being that there is also a separate table of users that link to these organizations, and I would like to unify them (therefore remove dupes so the users link to the same organization instead of dupe orgs). But I would like part manually so I don't screw anything up, but I would still need a statement returning the IDs of all the dupe orgs so I can go through the list of users. Any help would be greatly appreciated. Thanks :)

  • Android - Views in Custom Compound Component are not inflated (findByView returns null)

    - by Julian Arz
    I have made a Custom Component in XML, consisting of a button with an imageview stacked on top of it: <myapp.widget.ClearableCaptionedButton xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <Button android:id="@+id/ccbutton_button" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center_vertical|left" android:textAppearance="?android:attr/textAppearanceMedium" android:background="@android:drawable/edit_text"/> <ImageView android:id="@+id/ccbutton_clear" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="5dip" android:layout_alignRight="@id/ccbutton_button" android:layout_alignTop="@id/ccbutton_button" android:layout_alignBottom="@id/ccbutton_button"/> </myapp.widget.ClearableCaptionedButton> extract of java source code: public class ClearableCaptionedButton extends RelativeLayout implements OnClickListener { ... public ClearableCaptionedButton(Context context, AttributeSet attrs) { super(context, attrs); // some stuff that works fine } .. protected void onFinishInflate() { super.onFinishInflate(); mButton = (Button) findViewById(R.id.ccbutton_button); mClear = (ImageView) findViewById(R.id.ccbutton_clear); mButton.setText(""); // error here: mButton == null } My problem is similar to this one. When i try to find the views inside the custom compound, findViewById returns null. But, as you can see, i already added super(context, attrs); to the constructor. i am using the custom component directly in xml layout, like this: <LinearLayout> <!-- some stuff --> <de.pockettaxi.widget.ClearableCaptionedButton android:layout_width="fill_parent" android:layout_height="wrap_content" app:caption="to"/> </LinearLayout> can anybody spot something? thanks.

  • Using jQuery.UI CSS Framework for DIV Styling

    - by Gordon
    Hi folks, a Project I am currently working on uses the jQuery UI framework for some of its widgets. To provide the user with a global look and feel I would like to use the framework also for its css stuff. I am implementing at the moment a dashboard like homepage, where the user can see an overall status of its data. This dashboard is build of some divs that should be aligned into a grid layout. I try to style the divs like follows <div class="ui-widget"> <div class="ui-widget-header">Box Header</div> <div class="ui-widget-content"> Content of the Box </div> </div> Later I would like to implement some draggable-and-sortable functionality. The Problem I am facing right now is that the boxes aren't properly aligned. Does anyone has a hint on using jQuery.UI for that kind of css work? I was studing the CSS framework documentation on jqueryui.com but there aren't that much information. best regards, Gordon

  • Python + QT + Gstreamer

    - by Ptterb
    Hi everyone, I'm working with PyQt and trying to get video from a webcam to play within a QT widget. I've found tutorials for C and Qt, and for python and gtk, but NOTHING for this combo of pyQt and gstreamer. Anybody get this working? This plays the video fine, but in a separate window: self.gcam = gst.parse_launch('v4l2src device=/dev/video0 ! autovideosink') self.gcam.set_state(gst.STATE_PLAYING) what I need is to get the overlay working so it's displayed within a widget on my GUI. Thanks, Gurus of the internet! ok, so I've gotten a lot farther, but still in need of some help. I'm actually writing this for Maemo, but the following code works fine on my linux laptop: class Vid: def __init__(self, windowId): self.player = gst.Pipeline("player") self.source = gst.element_factory_make("v4l2src", "vsource") self.sink = gst.element_factory_make("autovideosink", "outsink") self.source.set_property("device", "/dev/video0") self.scaler = gst.element_factory_make("videoscale", "vscale") self.window_id = None self.windowId = windowId self.player.add(self.source, self.scaler, self.sink) gst.element_link_many(self.source,self.scaler, self.sink) bus = self.player.get_bus() bus.add_signal_watch() bus.enable_sync_message_emission() bus.connect("message", self.on_message) bus.connect("sync-message::element", self.on_sync_message) def on_message(self, bus, message): t = message.type if t == gst.MESSAGE_EOS: self.player.set_state(gst.STATE_NULL) elif t == gst.MESSAGE_ERROR: err, debug = message.parse_error() print "Error: %s" % err, debug self.player.set_state(gst.STATE_NULL) def on_sync_message(self, bus, message): if message.structure is None: return message_name = message.structure.get_name() if message_name == "prepare-xwindow-id": win_id = self.windowId assert win_id imagesink = message.src imagesink.set_property("force-aspect-ratio", True) imagesink.set_xwindow_id(win_id) def startPrev(self): self.player.set_state(gst.STATE_PLAYING) print "should be playing" vidStream = Vid(wId) vidStream.startPrev() where wId is the window id of the widget im trying to get to display the output in. When I run this on the N900, the screen goes black and blinks. Any ideas? I'm dying here!

  • Loading JSON-encoded AJAX content into jQuery UI tabs

    - by pocketfullofcheese
    We want our of our AJAX calls in our web app to receive JSON-encoded content. In most places this is already done (e.g. in modals) and works fine. However, when using jQueryUI's tabs (http://jqueryui.com/demos/tabs/) and their ajax functionality, only plaintext HTML can be returned (i.e. from the URLs specified in the a tags below). How do I get the tab function to recognize that on each tab's click, it will be receiving JSON-encoded data from the specified URL, and to load in the .content index of that JSON? $(function() { $('div#myTabs').tabs(); }); <div id="mytabs" class="ui-tabs ui-widget ui-widget-content ui-corner-all"> <ul class="ui-tabs-nav ui-helper-reset ui-helper-clearfix ui-widget-header ui-corner-all"> <li class="ui-state-default ui-corner-top"><a href="/url/one">Tab one</a></li> <li class="ui-state-default ui-corner-top"><a href="/url/two">Tab two</a></li> </ul> </div>

  • Using multiple QStyledItemDelegate with stylesheets

    - by Shane Holloway
    I'm creating a styled QTreeView using double-dispatch to resolve specific delegate for data items, which is working great. I subclassed the delegates from QStyledItemDelegate to take advantage of stylesheets, enabling the designers to style the UI outside of the code. Unfortunately, I have been unable to address different styles from the CSS. How do I select and use the item sub-control style specified in the stylesheet? The CSS I'm testing with: QTreeView::item:selected { background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #dddddd, stop: 1 #888888); } QTreeView::item:selected[role="title"] { background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #fde7ef, stop: 1 #f1cbda); } QTreeView::item:selected[role="entry"] { background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #e7effd, stop: 1 #cbdaf1); } My delegate rendering classes: class VisitingDelegate(QtGui.QAbstractItemDelegate): def __init__(self, parent=None): super(VisitingDelegate,self).__init__(parent) roles = {} self.renderRoles = roles d = TitleDelegate(parent) d.setProperty("role", "title") roles['title'] = d d = EntryDelegate(parent) d.setProperty("role", "entry") roles['entry'] = d def delegateForIndex(self, mi): role = mi.model().data(mi, "renderRole") return self.renderRoles[role] def paint(self, painter, option, mi): dg = self.delegateForIndex(mi) return dg.paint(painter, option, mi) def sizeHint(self, option, mi): dg = self.delegateForIndex(mi) return dg.sizeHint(option, mi) class TextDocumentDelegate(QtGui.QStyledItemDelegate): fmt = "<font color='%(color)s'>%(text)s</font)>" def paint(self, painter, option, mi): painter.save() opt = QtGui.QStyleOptionViewItemV4(option) self.initStyleOption(opt, mi) opt.text = '' style = opt.widget.style() style.drawControl(style.CE_ItemViewItem, opt, painter, opt.widget) textRect = style.subElementRect(style.SE_ItemViewItemText, opt, opt.widget); doc = self.asTextDoc(option, mi) painter.translate(textRect.topLeft()) doc.drawContents(painter) painter.restore() def sizeHint(self, option, mi): doc = self.asTextDoc(option, mi) sz = doc.size() sz = QtCore.QSize(sz.width(), sz.height()) return sz def asTextDoc(self, option, mi): info = {} info['text'] = mi.model().data(mi, Qt.DisplayRole) doc = QtGui.QTextDocument() doc.setDefaultFont(option.font) pal = option.palette if option.state & QtGui.QStyle.State_Selected: color = pal.color(pal.HighlightedText) else: color = pal.color(pal.Text) info['color'] = color.name() doc.setHtml(self.fmt % info) return doc class EntryDelegate(TextDocumentDelegate): pass class TitleDelegate(TextDocumentDelegate): fmt = "<h3><font color='%(color)s'>%(text)s</font)></h3>"

  • How do I use a different image for each JQuery UI Slider handle

    - by Tom
    I'm using a JQuery UI slider which has two handles (a.k.a range slider). I know how to style the first handle: .ui-slider-horizontal .ui-slider-handle {background: white url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat scroll 50% 50%;} But how do I style the second handle differently? Using Firebug I can see Jquery does not uniquely identify each handle: <div id="hourlyRateSlider" class="ui-slider ui-slider-horizontal ui-widget ui-widget-content ui-corner-all"> <div class="ui-slider-range ui-widget-header" style="left: 26%; width: 46%;"/> <a class="ui-slider-handle ui-state-default ui-corner-all" href="#" style="left: 26%;"/> <a class="ui-slider-handle ui-state-default ui-corner-all" href="#" style="left: 72%;"/> </div> So I imagine I have to use either a CSS child selector which could be cross-browser problematic. Or I could use some JQuery trickery to add a CSS class to the second handle? Anyone done this in a neat way before?

  • How do I set YUI2 paginator to select a page other than the first page?

    - by Jeremy Weathers
    I have a YUI DataTable (YUI 2.8.0r4) with AJAX pagination. Each row in the table links to a details/editing page and I want to link from that details page back to the list page that includes the record from the details page. So I have to a) offset the AJAX data correctly and b) tell YAHOO.widget.Paginator which page to select. According to my reading of the YUI API docs, I have to pass in the initialPage configuration option. I've attempted this, but it doesn't take (the data from AJAX is correctly offset, but the paginator thinks I'm on page 1, so clicking "next" takes me from e.g. page 6 to page 2. What am I not doing (or doing wrong)? Here's my DataTable building code: (function() { var columns = [ {key: "retailer", label: "Retailer", sortable: false, width: 80}, {key: "publisher", label: "Publisher", sortable: false, width: 300}, {key: "description", label: "Description", sortable: false, width: 300} ]; var source = new YAHOO.util.DataSource("/sales_data.json?"); source.responseType = YAHOO.util.DataSource.TYPE_JSON; source.responseSchema = { resultsList: "records", fields: [ {key: "url"}, {key: "retailer"}, {key: "publisher"}, {key: "description"} ], metaFields: { totalRecords: "totalRecords" } }; var LoadingDT = function(div, cols, src, opts) { LoadingDT.superclass.constructor.call( this, div, cols, src, opts); // hide the message tbody this._elMsgTbody.style.display = "none"; }; YAHOO.extend(LoadingDT, YAHOO.widget.DataTable, { showTableMessage: function(msg) { $('sales_table_overlay').clonePosition($('sales_table').down('table')). show(); }, hideTableMessage: function() { $('sales_table_overlay').hide(); } }); var table = new LoadingDT("sales_table", columns, source, { initialRequest: "startIndex=125&results=25", dynamicData: true, paginator: new YAHOO.widget.Paginator({rowsPerPage: 25, initialPage: 6}) }); table.handleDataReturnPayload = function(oRequest, oResponse, oPayload) { oPayload.totalRecords = oResponse.meta.totalRecords; return oPayload; }; })();

  • In IE8, jquery-ui's dialog set the height of its contents to zero. How can I fix this?

    - by brahn
    I am using jquery UI's dialog widget to render a modal dialog in my web application. I do this by passing the ID of the desired DOM element into the following function: var setupDialog = function (eltId) { $("#" + eltId).dialog({ autoOpen: false, width: 610, minWidth: 610, height: 450, minHeight: 200, modal: true, resizable: false, draggable: false, }); }; Everything works just fine in Firefox, Safari, and Chrome. However, in IE 8 when the dialog is opened only the div.ui-dialog-titlebar is visible -- the div.ui-dialog-contents are not. The problem seems to be that while in the modern browsers, the div.ui-dialog-contents has a specific height set in its style, i.e. after opening the dialog, the resulting HTML is: <div class="ui-dialog-content ui-widget-content" id="invite-friends-dialog" style="width: auto; min-height: 198px; height: 448px">...</div> while in IE8 the height style attribute is set to zero, and the resulting HTML is: <div class="ui-dialog-content ui-widget-content" id="invite-friends-dialog" style="min-height: 0px; width: auto; height: 0px">...</div> What do I need to do to get the height (and min-height) style attributes set correctly?

  • What information should a SVN/Versioned file commit comment contain?

    - by RenderIn
    I'm curious what kind of content should be in a versioned file commit comment. Should it describe generally what changed (e.g. "The widget screen was changed to display only active widgets") or should it be more specific (e.g. "A new condition was added to the where clause of the fetchWidget query to retrieve only active widgets by default") How atomic should a single commit be? Just the file containing the updated query in a single commit (e.g. "Updated the widget screen to display only active widgets by default"), or should that and several other changes + interface changes to a screen share the same commit with a more general description like ("Updated the widget screen: A) display only active widgets by default B) added button to toggle showing inactive widgets") I see subversion commit comments being used very differently and was wondering what others have had success with. Some comments are as brief as "updated files", while others are many paragraphs long, and others are formatted in a way that they can be queried and associated with some external system such as JIRA. I used to be extremely descriptive of the reason for the change as well as the specific technical changes. Lately I've been scaling back and just giving a general "This is what I changed on this page" kind of comment.

  • Concatenate 2 text elements on a line with full-width border using CSS only

    - by Michael Horne
    Okay, I'm a newbie to CSS3, so please be gentle. ;-) I'm working with some Wordpress code (Woocommerce plugin, to be exact), and I'm trying to format a line of code in a sidebar so that 2 separate text items (one in an <a, the other in a <span are all on the same line, the full width of the column, and with a bottom border. It looks something like this (except the bottom border on each text do not go all the way across the enclosing sidebar box): http://www.dalluva.com/temp/browse-catalog.JPG (sorry, I'm new and can't post inline images yet) Here's the code fragment I'm trying to live with (i.e. I don't want to change it): <div class="widget"> ... <ul class="product-categories"> <li class="cat-item"> <a href="http://localhost/dalluva/shop/product-category/books/">Books</a> <span class="count">(5)</span> </li> ... And here's the CSS I have now: .widget ul li a { border-bottom: 1px solid #e9e9e9; line-height:1.0; padding: 5px 0 5px 22px; display: inline-block; } .widget ul li span { border-bottom: 1px solid #e9e9e9; line-height: 1.0; padding: 5px 0 5px 0; display: inline-block; } The output in the image above looks right for this CSS code, but when I change the 'span' CSS to include a width:100%, it causes the span element to wrap to the next line, looking like this: http://www.dalluva.com/temp/browse-catalog-2.JPG I've played with white-space:nowrap, overflow:hidden, etc, but I can't seem to find a way to have both the <a and the <span text on the same line with the border extending the full width of the column. Any suggestions on getting the desired effect through CSS only? Thanks. Michael

  • How to patch an S4 method in an R package?

    - by Richie Cotton
    If you find a bug in a package, it's usually possible to patch the problem with fixInNamespace, e.g. fixInNamespace("mean.default", "base"). For S4 methods, I'm not sure how to do it though. The method I'm looking at is in the gWidgetstcltk package. You can see the source code with getMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk")) I can't find the methods with fixInNamespace. fixInNamespace(".svalue", "gWidgetstcltk") Error in get(subx, envir = ns, inherits = FALSE) : object '.svalue' not found I thought setMethod might do the trick, but setMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk"), definition = function (obj, toolkit, index = NULL, drop = NULL, ...) { widget = getWidget(obj) sel <- unlist(strsplit(tclvalue(tcl(widget, "selection")), " ")) if (length(sel) == 0) { return(NA) } theChildren <- .allChildren(widget) indices <- sapply(sel, function(i) match(i, theChildren)) inds <- which(visible(obj))[indices] if (!is.null(index) && index == TRUE) { return(inds) } if (missing(drop) || is.null(drop)) drop = TRUE chosencol <- tag(obj, "chosencol") if (drop) return(obj[inds, chosencol, drop = drop]) else return(obj[inds, ]) }, where = "package:gWidgetstcltk" ) Error in setMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk"), : the environment "gWidgetstcltk" is locked; cannot assign methods for function ".svalue" Any ideas?

  • How to repeatedly show a Dialog with PyGTK / Gtkbuilder?

    - by Julian
    I have created a PyGTK application that shows a Dialog when the user presses a button. The dialog is loaded in my __init__ method with: builder = gtk.Builder() builder.add_from_file("filename") builder.connect_signals(self) self.myDialog = builder.get_object("dialog_name") In the event handler, the dialog is shown with the command self.myDialog.run(), but this only works once, because after run() the dialog is automatically destroyed. If I click the button a second time, the application crashes. I read that there is a way to use show() instead of run() where the dialog is not destroyed, but I feel like this is not the right way for me because I would like the dialog to behave modally and to return control to the code only after the user has closed it. Is there a simple way to repeatedly show a dialog using the run() method using gtkbuilder? I tried reloading the whole dialog using the gtkbuilder, but that did not really seem to work, the dialog was missing all child elements (and I would prefer to have to use the builder only once, at the beginning of the program). [SOLUTION] As pointed out by the answer below, using hide() does the trick. But one has to take care that the dialog is in fact destroyed if one does not catch its "delete-event". A simple example that works is: import pygtk import gtk class DialogTest: def rundialog(self, widget, data=None): self.dia.show_all() result = self.dia.run() def destroy(self, widget, data=None): gtk.main_quit() def closedialog(self, widget, data=None): self.dia.hide() return True def __init__(self): self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) self.window.connect("destroy", self.destroy) self.dia = gtk.Dialog('TEST DIALOG', self.window, gtk.DIALOG_MODAL | gtk.DIALOG_DESTROY_WITH_PARENT) self.dia.vbox.pack_start(gtk.Label('This is just a Test')) self.dia.connect("delete-event", self.closedialog) self.button = gtk.Button("Run Dialog") self.button.connect("clicked", self.rundialog, None) self.window.add(self.button) self.button.show() self.window.show() if __name__ == "__main__": testApp = DialogTest() gtk.main()
