  • swing layout: vertical flow

    - by pstanton
    Hi All, What LayoutManager should I use to achieve a transposed version of FlowLayout? Essentially, I want a vertical list which occupies multiple columns if it can't fit all of it's components within one column. +------------------------+ | item 1 | | item 2 | | item 3 | | item 4 | | item 5 | | item 6 | | item 7 | | item 8 | +------------------------+ or +------------------------+ | item 1 item 7 | | item 2 item 8 | | item 3 | | item 4 | | item 5 | | item 6 | +------------------------+

  • c++ figuring out memory layout of members programatically

    - by anon
    Suppose in one program, I'm given: class Foo { int x; double y; char z; }; class Bar { Foo f1; int t; Foo f2; }; int main() { Bar b; bar.f1.z = 'h'; bar.f2.z = 'w'; ... some crap setting value of b; FILE *f = fopen("dump", "wb"); // c-style file fwrite(&b, sizeof(Bar), 1, f); } Suppose in another program, I have: int main() { File *f = fopen("dump", "rb"); std::string Foo = "int x; double y; char z;"; std::string Bar = "Foo f1; int t; Foo f2;"; // now, given this is it possible to read out // the value of bar.f1.z and bar.f2.z set earlier? } WHat I'm asking is: given I have the types of a class, can I figure out how C++ lays it out?

  • vaadin custom layout setting a text area in a table with the location attribute

    - by user3717298
    I need to set a text area in the html template and use it as a custom component in vaadin the html snippet is as below <table> <tr> <td> JUNK SENTENCE </td> <td> <div location="HEADIN"></div> <div location="Details"></div> <div location="Attachment"></div> </td> <td> <p>School of more than 50 students univer versities.</p> </td> </tr> </table> All the place holders are working and displays data but the "details" holder should be a text area. as the text is a lot over there so I tried the below way but it just turned the place holder to text vaadin could not manipulate / identify the "Details" place holder. I tried the below way i set - in side the text area tag. <textarea rows="4" cols="50"> </textarea> and again i tried this way too which also did not work. <textarea rows="4" cols="50" location="Details"> </textarea> Any guidance would be appreciated to solve this I am setting the needed values from a formfeildfactory and these values are set by implementing the Vaadin Custom field class(in case it helps some more to identify)

  • Automatic VisualState Manager in Silverlight

    - by Matt
    If you create a simple button and then choose Edit Template - Edit a Copy, Blend will automatically generate a style area, along with all the button states (MouseEnter, MouseLeave, Pressed, etc). No where in the code behind or auto generated style area does it say that on a "MouseOver" event, change the state to "MouseOver", but it still manages to work! Is the only way to change a button's state have to be done the code behind using the VisualStateManager.GoToState method, or can you change it much like CSS does (a:hover) using the VisualStateManager? From my experience, setting just doesn't seem to do the trick.

  • Slick PHP based image manager for managing user profile images

    - by franko75
    Hi, I'm just throwing this out there as I'm plodding my way through creating a Member Photo album on a site i'm working on, where they can login and upload their photos to a personal gallery. I want this to be nice and lightweight, but still slick and "modern" with a modal based interface for the user. I'm surprised though that there is seemingly nothing open source out there which fits the bill - I've done a few searches on Google to no avail and can't seem to find anything. Lots of bloated photo galleries out there but nothing looks like it has been developed using more recent technologies. Is anyone aware of anything which might suit what I'm looking for? I'm fully prepared to try and code it myself but I'd be delighted if I didn't have to! Pure laziness you might say, but there's no point reinventing the wheel.

  • C++ Basic Class Layout

    - by Spencer
    Learning C++ and see the class laid out like this: class CRectangle { int x, y; public: void set_values (int,int); int area () {return (x*y);} }; void CRectangle::set_values (int a, int b) { x = a; y = b; } I know Java and methods(functions) in Java are written within the class. The class looks like a Java interface. I know I can write the class like this: class CRectangle { int x, y; public: void set_values (int a, int b) { x = a; y = b; }; int area () {return (x*y);} }; But is there a difference or standard?

  • Javafx Layout problem with VBox & HBoxes

    - by pgpatrudu
    When I run the following, I noticed spacing between nodes; My research revealed that - 1) If I do not add any text to win1 via setwininfo, then there is no problem. 2) When I include this code in a larger app, and when a button click is reveived from some where else, mysteriously the spacing gets corrected. 3) I tried binding the win1 & win2 nodes to content of scene - but no luck. def mainframew : Integer = 250; def mainframeh : Integer = 500; class CtrlWindow extends CustomNode { var wininfo : String; var fsize : Integer; var width : Integer; public function setWinInfo(info : String) { wininfo = info; } override protected function create () : Node { var win = Group { content: [ VBox { content: [ Text { font : Font { size: fsize } content : bind wininfo textAlignment : TextAlignment.CENTER // did not work } ] } Rectangle { width: width, height: 25 fill: Color.TRANSPARENT strokeWidth : 2 stroke : Color.SILVER } ] } return win; } } public function run(args : String[]) { var win1 = CtrlWindow{fsize:14, width:mainframew}; var win2 = CtrlWindow{fsize:14, width:mainframew}; win1.setWinInfo("The spacing between these nodes"); win2.setWinInfo("corrects itself after receiving an event"); Stage { title : "MyApp" scene: Scene { width: mainframew height: mainframeh content: [ VBox { spacing: 0 content: [ HBox { content: win1 } HBox { content: win2 } ] } ] } }

  • Source code dependency manager for C++

    - by 7vies
    There are already some questions about dependency managers here, but it seems to me that they are mostly about build systems, while I am looking for something targeted purely at making dependency tracking and resolution simpler (and I'm not necessarily interested in learning a new build system). So, typically we have a project and some common code with another project. This common code is organized as a library, so when I want to get the latest code version for a project, I should also go get all the libraries from the source control. To do this, I need a list of dependencies. Then, to build the project I can reuse this list too. I've looked at Maven and Ivy, but I'm not sure if they would be appropriate for C++, as they look quite heavily java-targeted (even though there might be plugins for C++, I haven't found people recommending them). I see it as a GUI tool producing some standardized dependency list which can then be parsed by different scripts etc. It would be nice if it could integrate with source control (tag, get a tagged version with dependencies etc), but that's optional. Would you have any suggestions? Maybe I'm just missing something, and usually it's done some other way with no need for such a tool? Thanks.

  • jQuery Mobile page overrides desktop HTML div layout

    - by batjko
    I'd like to use jQuery mobile on my desktop page. I'm probably thinking of this wrongly, but I tried simply inserting a page element into an existing standard div, like this: <body> <div id="left_sidebar"> [...] </div> <div id="mylist" data-role="page"> <div data-role="listview"> [list items bla bla] </div> </div> <div id="right_sidebar"> [...] </div> <div id="site_footer"> (c) bla blub </div> </body> ...hoping that only the middle part displays the "mobile" page elements. However, that page div seems to override the entire site and turns the whole body into a mobile page (albeit displaying my listview item nicely... across the entire screen). Any idea what to do? Advice is much appreciated.

  • Subdomain Routing Rules (using chaining) Broke after upgrading to Zend Framework 1.9.5, but only for

    - by Dan
    I asked a similar question months ago (see How do I write Routing Chains for a Subdomain in Zend Framework in a routing INI file?), on how to write chaining rules in an app.ini format. The answer to this question worked wonderfully! Now, however, I have upgraded to the latest version of the Zend Framework 1.9.5 (I needed to upgrade for another issue) and now my subdomains no longer work! To clarify, if I visit subdomain.domain.com, it does not recognize my rule. However, if I visit subdomain.domain.com/somepage/ it does recognize my routing rule. Here is my code: ;; the following is apparently being ignored, and does not work routes.manager.type = "Zend_Controller_Router_Route_Hostname" routes.manager.route = "manager.sitename.com" routes.manager.defaults.module = "manager" ;; this is not being ignored and works! routes.manager.chains.settings.type = "Zend_Controller_Router_Route_Static" routes.manager.chains.settings.route = "/settings" routes.manager.chains.settings.defaults.controller = "manager" routes.manager.chains.settings.defaults.action = "settings" So for example, if I go to manager.sitename.com, it just redirects to my default index and controller (does not access the module, $this-getRequest()-getModuleName() is blank). However, if I go to manager.sitename.com/settings, the page comes up! This app.ini configuration works fine in ZF 1.7.8, But now since I upgraded to 1.9.5, it no longer works. I have tried adding routes.manager.defaults.controller = "manager" and routes.manager.defaults.action = 'index" to my configuration as well, but this didn't work. There is not much out there on the internet with chaining and app.ini dealing with Zend Framework. Any help on this issue would be greatly appreciated.

  • Iphone UI Size / Layout Resource?

    - by blindJesse
    Is anyone aware of a website or download to reference for the size of UI elements or standard iphone interface stuff? What I mean is something that gives the height of elements like the status bar, tab bar, navigation bar, default tableviewcell height (and such things as width of accessory view, indentation, etc), default icon sizes, default font sizes for UI elements (if they need to be mimicked, for instance), etc etc etc. It's amazing how many times I have to go back to find a reference or estimate the size and position of a standard element. It seems like it would be an invaluable resource that could fit on a printed page or two.

  • Qt - 2 QMainWindow glued - Size of Layout

    - by user1773603
    I have a main window that I center this way in main.cpp : int main(int argc, char *argv[]) { QApplication app(argc, argv); QMainWindow *qmain = new QMainWindow; Ui_MainWindow ui; ui.setupUi(qmain); QRect r = qmain->geometry(); r.moveCenter(QApplication::desktop()->availableGeometry().center()); qmain->setGeometry(r); qmain->show(); return app.exec(); } In this "qmain" main window, I can create another QMainWindow and I try to make stick (or glue I don't know how to say) the two windows. Actually, I would like the right-top corner of the first one to be located at the left-top of the second one. For this, I use the following Ui_MainWindow's member function : void Ui_MainWindow::generate_IC() { qmenu = new QMainWindow; DiskMenu = new Ui_DiskGalMenu; DiskMenu->setupUi(qmenu); setInitialDiskMenuPosition(qmenu, this); qmenu->show(); } and the setInitialDiskMenuPosition : void Ui_MainWindow::setInitialDiskMenuPosition(QMainWindow *MainWindow, Ui_MainWindow *parent) { QSize size = parent->widget->size(); QDesktopWidget* desktop = QApplication::desktop(); int width = desktop->width(); int height = desktop->height(); int mw = size.width(); int mh = size.height(); int right = (width/2) + (mw/2); int top = (height/2) - (mh/2); MainWindow->move(right, top); } But the problem is that I don't get exactly what I want since the centralwidget size "parent- widget-size()" only returns the size of the widget and not the whole "qmain" parent window. So I have a light shift because the borders of the "qmain" window are not taken in account like it is shown below : If I could have access to the size of the whole parent window... If anyone could help me

  • New line (in the code) after <li> element breaking layout

    - by BT643
    Weirdly, I've never come across this issue before, but I've just started making a site and the top navigation isn't playing nicely. I want a small amount of white space between each menu item, but when I have new lines between my <li> elements and my <a> elements in my IDE (Netbeans), the white space disappears, yet it looks fine if I have <li><a></a></li> all on the same line. I was always under the impression html ignored white space in the code. I've checked for any weird characters causing problems in other text editors and can't find anything. Here's the code... Like this the menu looks correct but code looks ugly (I know it looks fine when it's this simple, but I'm going be adding more complexity in which makes it look awful all on one line): <ul id="menu"> <li><a href="#">About</a></li> <li class="active"><a href="<?php echo site_url("tracklist"); ?>">Track List</a></li> <li><a href="<?php echo site_url("stats"); ?>">Stats</a></li> <li><a href="#">Stats</a></li> </ul> Like this the menu looks wrong but code looks fine: <ul id="menu"> <li> <a href="#">About</a> </li> <li class="active"> <a href="<?php echo site_url("tracklist"); ?>">Track List</a> </li> <li> <a href="<?php echo site_url("stats"); ?>">Stats</a> </li> <li> <a href="#">Stats</a> </li> </ul> Here's the css: #menu { float: right; } #menu li { display: inline-block; padding: 5px; background-color: #932996; border-bottom: solid 1px #932996; } #menu li:hover { border-bottom: solid 3px #FF0000; } #menu li.active { background-color: #58065e; } I'm sure it's something simple I'm doing wrong... but can someone shed some light on this for me? Sorry for the lengthy post (my first on stackoverflow).

  • c++: see compiled object layout

    - by horsthahn
    Hi, is there a way - much like the way i can see the result of preprocessing when using 'gcc -E' - to see what my objects look like once the compiler compiled them into object files? I am not too good in reading assembler, so an advice to get the results as text would be nice .. or at least a little 'howto read the constructor intructions' or 'howto find the constructor' ... I am talking about gcc/g++, but a solution including msvc would be fine. Thanks!
