  • exposing subcontrols from the custom widget plugin in QT

    - by Santosh
    I am using QT 4.3. I have created one custom widget plugin. I could be able to show it in the desiner tool box as well as use it on the form with no problem. This custom widget internally holds QGroupBox, QLabel, QTextEdit. Now I want to apply the styles to individual componets of this custom widget. I want to expose these internal conrols as sub-control and style them. This would be similar to tear subcontrol of QTabWidget. In style sheet we can refer it as QTabWidget::tear... Is there any way by which I can do similar thing with my custom widget?

  • Is is possible to make a shaped, alpha-blended dialog?

    - by jgaa
    I'm making a non-rectangular dialog, modelled over an image from Photoshop (the image is the background of the dialog, and the user will see trough the transparent part of the image). I'ts like a dashboard-style window for a media-app with a few custom-drawn controls. Most of the background-image is either opaque or 100% transparent - but in between there is a thin area of partially transparent pixels, ment to blend the image smootly into the background. This works great for web-graphics, but I have not found a way to make this work for Windows windows. I'm using the Windows Template Library (WTL), msvc 2008 - and the app must run on Windows XP as well as Vista and Windows 7. Currently, I'm simply using the opaque part of the background-image to create a GDI clipping-region, but this gives pretty rough edges. Does anyone know about any API functions to accomplish this (part of WTL, or reachable from WTL)?

  • How to merge JOptionPane and Frame into one

Currently I have a very basic file viewer working as follows : - in JOptionPane I browse for files, and set some variables to display (colors, line connecting etc) - previous windows loads a frame with drawn points Code : http://paste.pocoo.org/show/220066/ Now I'd like to throw it into one window, with JMenu for selecting files and changing display parameters. How to get started ? Should I rewrite everything to JDialog ?

  • Handling right-click within a MenuItem

    - by tylerl
    Is it possible to check for a right-click on a menu item in .NET? It appears that the framework doesn't expose it as an Event, but I've seen other applications (like Chrome and Firefox) which allow you to bring up a right-click context menu for a menu item. Presumably with a little event-loop magic you can do the same thing in .NET, right?

  • JButtons re-enable themselves after being disabled

    - by Anarchist
    I have an array of JButtons which form a keypad interface. After six numbers are entered I want to disable the keypad so that no further numbers can be entered by the user. I have written the code and the buttons do disable until the mouse hovers above any of them, then the buttons seem to re-enable themselves and run actionEvents added to them. The full code is available here. Possible things that I think are wrong. There is some sort of MouseListener which is ignoring when I set button.setEnabled(false); I haven't separated attributes from the buildGUI(); correctly, I only did this anyway so that the inner class could access them. Possibly something to do with the gridLayout as disabling the buttons seems to work for my services JPanel buttons.

  • "Correct" Dialog / UI font on Windows

    - by peterchen
    When creating a control (e.g. an edit control) on the fly using CreateWindow, it usually starts out with an ugly (boldish sans serif) font. Usually I wok around that by grabbing the parent dialog's font, and setting it to the control - I can't even say if this is a good idea. How do I "legally" fetch the right font?

  • Delay KeyUp Action if User is Typing (C#)

    - by Kirk
    I have a function that is being called when the user is typing in a search box. I want to wait for the user to finish typing before I actually execute the function. I know how to easily accomplish this in JavaScript with timeouts, but how would I go about doing the same thing in C#? Also, how long should I wait before I assume the user is done typing? 100ms?

  • How to make a plugin for Finder to browse zip-archives as folders?

    - by Andrei
    What really surprises me is lack of some essential functionality in Finder, when one migrates from Windows to OS X. One of the things is a possibility to open an archive as a folder, i.e. staying in the directory tree and being able to drag and drop files from the archive to folders in the tree, sidebar etc. What would you do to enable such functionality?

  • Creating an invisible button in Java Swing

    - by AniDev
    Hello, I have seen many times on Java Swing GUIs buttons that look like images until the mouse rolls over them. They appear to not have their content area filled. When the mouse rolls over them, the content area fills in but the button looks as though the mouse is not hovering over it. An example of this would be the toolbar of buttons used to activate each demo in SwingSet2. How is this effect possible? Thanks!

  • Adding multiple views to a listview.

    - by hwrdprkns
    Hey guys, I tried to add these views to list view using this kind of factory but everytime I try and add the view to a ListActivity, it comes up with nothing. What am I doing wrong? I set my list views like so: List<View> views = new ArrayList<View>(); for(int x =0;x<tagg_views.size();x++) { lv.addHeaderView(views.get(x)); }

  • Type-aware rendering (and editing) of tabular data in pyqt4

    - by pihentagy
    I would like to have a very short / minimal example of how to create some tabular widget with different types of item in it. In the first round let's say I'd like to render [["Hello", 12, True], ["World", 13, False]] (Hello as string, 12 as number (right-align), True as a checkbox for eg.), but it would be nice to have Dates, Colors, and other type of info. Next round: editing (integer with spinbox, maybe sometimes a combobox is handy, but that may not work out of the box). There must be a simple solution, but I couldn't find...

  • How to change the icon in the title bar in R?

    - by Jared
    I just installed R 2.11.0-x64 onto my Windows 7 Professional machine. With my previous installations of R (2.10.1 32 bit was the most recent) the little icon that appeared in the title bar and in the taskbar at the bottom of windows was the R "R." Now however, the icon almost looks like a small windows Task Manager. I know this isn't a code issue, but it affects me as I flip between windows. Is there a way to put the "R" icon back in there? Would it be an R setting or a Windows setting?

  • Javascript plugins design pattern like jQuery

    - by Marco Demaio
    Could someone write down a very simple basic example in javascript to conceptualize (and hopefully make me understand) how the jQuery plugin design pattern is done and how it works? I'm not interested in how creating plugin for jQuery (so no jQuery code here at all). I'm interested in a simple explanation (maybe with a bit of Javascript code) to explain how it is done the plugin concept. Plz do not reply me to go and read jQuery code, I tried, but I it's too complex, otherwise I would have not post a question here.

  • On demand population of dropdown menu Java/Swing?

    - by Cookie Monster
    When I code a popup menu, I can check the mouse event and then before calling show() prepare the menu. Now I want a similar functionality for drop down menus, that live in the menu bar. For example I have the following menu bar layout: Menu 1 MenuItem 1.1 MenuItem 1.1.1 MenuItem 1.1.2 .. MenuItem 1.1.n Menu 2 Basically I want to generate the list MenuItem 1.1.1, MenuItem 1.1.2, ..., MenuItem 1.1.n dynamically when the drop down menu is invoked and before it is shown. How could I do this in Java/Swing? Best Regards

  • Creating a Skill Calculator for Runescape

    - by USDblades
    I am beginning C++. I have a long way to go and I am one to never stop learning. I want to create a project for myself that will allow me to learn as I go. It will also give me the motivation and possibly add to my portfolio when I graduate. The runescape skill calculator will ask for your current experience in the current skill of your choosing and your desired level. For Example: my woodcutting experience is 60 and I want to get to lvl 5 which is 120 exp. That means im 60 experience away. by cutting oak logs I get 5 experience per log. The calculator would tell me I need to cut 12 Oak logs. All these numbers are made up. So to my question. Where would I even begin? Hoping it would have buttons to press.

  • How to make a plugin for [Path] Finder to browse zip-archives as folders?

    - by Andrei
    What really surprises me is lack of some essential functionality in Finder, when one migrates from Windows to OS X. One of the things is a possibility to open an archive as a folder, i.e. staying in the directory tree and being able to drag and drop files from the archive to folders in the tree, sidebar etc. What would you do to enable such functionality? Update Path Finder is an awesome shareware app, which I am going to use instead of the standard Finder (as quite many Mac users do), so I am more interested in a plug-in for Path Finder to browse archives. There is a possibility to browse packages (check the View Options), so I believe it is possible to extend it to archives. There is also a SDK for making plugins for Path Finder. The only question - how to make the plugin, so all struggling people get finally happy?
