• How to get rid of a JQUERY APPEND GIve the following code...

  - by nobosh

  Given the following lines of code which is using JQTOUCH: $('#customers').bind('pageAnimationEnd', function(e, info){ if (!$(this).data('loaded')) { $('.loadingscreen').css({'display':'block'}); $(this).append($('<div> </div>'). load('/mobile/ajax/customers/ .info', function() { $(this).parent().data('loaded', true); $('.loadingscreen').css({'display':'none'}); })); } }); How can I get ride of the .append($(' '). It used to be append($('loading') but I didn't need that and now it seems like a waste of processing time to have in the function. Is it possible?

• How can I customize the title bar on JFrame?

  - by Jonas

  I would like to have a customized title bar in my Java Swing desktop application. What is the best way to do that? I can use a "Swing-title bar" by using the following code in the constructor for my JFrame: this.setUndecorated(true); this.getRootPane().setWindowDecorationStyle(JRootPane.FRAME); But how do I customize it? Is there any UI delegates that I can override or do I have to implement my own title bar from scratch? I want something like Lawson Smart Office: Or like Trend Micro Internet Security:

• Will C++1x support __stdcall or extern "C" capture-nothing lambdas?

  - by Daniel Trebbien

  Yesterday I was thinking about whether it would be possible to use the convenience of C++1x lambda functions to write callbacks for Windows API functions. For example, what if I wanted to use a lambda as an EnumChildProc with EnumChildWindows? Something like: EnumChildWindows(hTrayWnd, CALLBACK [](HWND hWnd, LPARAM lParam) { // ... return static_cast<BOOL>(TRUE); // continue enumerating }, reinterpret_cast<LPARAM>(&myData)); Another use would be to write extern "C" callbacks for C routines. E.g.: my_class *pRes = static_cast<my_class*>(bsearch(&key, myClassObjectsArr, myClassObjectsArr_size, sizeof(my_class), extern "C" [](const void *pV1, const void *pV2) { const my_class& o1 = *static_cast<const my_class*>(pV1); const my_class& o2 = *static_cast<const my_class*>(pV2); int res; // ... return res; })); Is this possible?

• Django admin proper urls inside listview

  - by hinnye

  Hi, My current target is to give users the chance to download CSV files from the admin site of my application. I successfully managed to create an additional column in the model's list view this way: def doc_link(self): return '<a href="files/%s">%s</a>' % (self.output, self.output) doc_link.allow_tags = True This shows the file name and creates the link, but sadly - because it's inside my 'searches' view - it has an URL: my_site/my_app/searches/files/13.csv. This is my problem, I would like to have my files stored in the admin media directory, like this: http://my_site/media/files/13.csv Does somebody know how to give url which points "outer" from the model's directory? Maybe somehow tell Django to use the ADMIN_MEDIA_PREFIX in the link? I'd really appreciate any help, thanks!

• Wrapping pre-made elements using GWT?

  - by user246114

  Hi, I've been working with GWT for awhile, I can't find a way to integrate it with a preexisting website which is a real downer. My page content is already generated for me using jsp, like: <div id='A'></div> <div id='B'></div> etc. there is no way for me to do something like this though: public void onModuleLoad() { SimplePanel spA = new SimplePanel( Document.getElementById("A")); spA.add(new Label("hello")); SimplePanel spB = new SimplePanel( Document.getElementById("B")); spB.setWidth("200px"); etc .. } seems like there's no way to just wrap a pre-existing element. Is this true, or am I missing how to do this? I need be able to wrap a bunch of elements like this, to manipulate them later on. I see TextBox, Button, a few other classes have wrap() methods, however nothing like that exists for elements, Thanks

• How to change code settings in eclipse

  - by Maven

  Sorry if the question title is confusing. Let me explain further. I am building a Java project with Eclipse. In my Java product I have conditionals that determine what code is included in the product and relies on static final constants for dead stripping. class BuildFlags { public static final boolean SOME_FLAG = true; // Need to set this programmatically } class SomeOtherClass { public void someMethod() { if (BuildFlags.SOME_FLAG) { // flag specific code } } } My question is how can I change BuildFlags.SOME_FLAG (above) so that I can run a special build without changing the source? Is there some way I can pass flags to the jvm (from eclipse) which I can then access to set this flag programatically?

• is there a limit on the number of times navigator.geolocation.getCurrentPostion can be called ?

  - by Raja

  Hi all, This is may not be a true programming question but deals with geolocation Api, hence hoping StackOverflow is the right place for this. I'm calling the navigator.geolocation.getCurrentPosition at every 3 seconds interval. After 10-15 tries the responses stop. So i'm wondering is there a limit on the number of calls being made, Or is it because i'm testing it with a desktop and hence instead of giving back the same response each time the API is waiting for a change of location. Anyone has any experiences to share ? Thanks

• Clear sqlalchemy reflection cache

  - by OrganicPanda

  Hi all, I'm using sqlalchemy's reflection tools to get a Table object. I do this because these tables are dynamic and tables/columns can change. Here's the code I'm using: def getTableByReflection(self, tableName, metadata, engine): return Table(tableName, metadata, autoload = True, autoload_with = engine) The problem is that when the above code is run twice it seems to return the same results regardless of whether or not the columns have changed. I have tried refreshing using the mysession.refresh(mytable) but that fails because the table is not attached to any metadata - which makes sense but then why am I seeing cached results? Is there any way to tell the metadata/engine/session to forget about this table and let me load it cleanly?

• strsplit in R with metacharacter

  - by user1429852

  I have received a large amount of data where the delimiter is a backslash (obviously a bad choice). I'm processing it in R for computation, and having a hard time finding how to split the string since the backslash is a metacharacter. For example, a string would look like this: "1128\0019\XA5\E2R\366\00=15" and I want to split it along the "\" character, but when I run the strsplit command: strsplit(tempStr, "\") Error in strsplit(tempStr, "\") : invalid regular expression '\', reason 'Trailing backslash' When I try to used the "fixed" option, it does not run because it is expecting something after the backslash: strsplit(tempStr, "\", fixed = TRUE) Unfortunately, I can't preprocess the data with another program because the data is generated daily. Please help and thanks!

• Python Textwrap - forcing 'hard' breaks

  - by Tom Werner

  I am trying to use textwrap to format an import file that is quite particular in how it is formatted. Basically, it is as follows (line length shortened for simplicity): abcdef <- Ok line abcdef ghijk <- Note leading space to indicate wrapped line lm Now, I have got code to work as follows: wrapper = TextWrapper(width=80, subsequent_indent=' ', break_long_words=True, break_on_hyphens=False) for l in lines: wrapline=wrapper.wrap(l) This works nearly perfectly, however, the text wrapping code doesn't do a hard break at the 80 character mark, it tries to be smart and break on a space (at approx 20 chars in). I have got round this by replacing all spaces in the string list with a unique character (#), wrapping them and then removing the character, but surely there must be a cleaner way? N.B Any possible answers need to work on Python 2.4 - sorry!

• Passing operator as a parameter

  - by nacho4d

  Hi, I want to have a function that evaluates 2 bool vars (like a truth table) for example: since T | F : T then myfunc('t', 'f', ||); /*defined as: bool myfunc(char lv, char rv, ????)*/ should return true; how can I pass the third parameter? (I know is possible to pass it as a char* but then I will have to have another table to compare operator string and then do the operation which is something I would like to avoid) Is it possible to pass an operator like ^(XOR) or ||(OR) or &&(AND), etc in a function/method? Thanks in advance

• JavaScript inheritance extend function

  - by Zach

  I'm having some trouble understanding the IF clause at the end of this function from Pro JavaScript Design Patterns: function extend(subClass, superClass) { var F = function() {}; F.prototype = superClass.prototype; subClass.prototype = new F(); subClass.prototype.constructor = subClass; subClass.superclass = superClass.prototype; if(superClass.prototype.constructor == Object.prototype.constructor) { superClass.prototype.constructor = superClass; } } The book explains that these lines ensure that the superclass's constructor attribute is correctly set, even if the superclass is the Object class itself. Yet, if I omit those three lines and do the following: function SubClass() {}; extend(SubClass, Object); alert(Object.prototype.constructor == Object); The alert says 'true', which means the superclass's constructor is set correctly even without those last three lines. Under what conditions, then, does this IF statement do something useful? Thanks.

• Android: how to make two TextViews placed in different lines if there is no enough space in one line

  I'am trying to organize two TextViews to behave like that: So, if there is enough space for both TextViews in line, android should place them in line. If there is no enough space, the second TextView must be placed on a next line with right alignment. <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <TextView android:id="@+id/takeoffCity" android:layout_width="wrap_content" android:layout_height="wrap_content" style="@style/flightItem" /> <TextView android:id="@+id/landingCity" android:layout_width="wrap_content" android:layout_height="wrap_content" style="@style/flightItem" /> </LinearLayout> <style name="flightItem" parent="@android:style/TextAppearance"> <item name="android:textSize">14dip</item> <item name="android:textColor">@color/flightItemFont</item> <item name="android:scrollHorizontally">true</item> <item name="android:textStyle">bold</item> </style>
