I have a QTreeView widget placed inside a QDockWidget:
I want to set the properties of the QTreeView, that it automatically fills the whole available client drawing area (similar as WinForms DockFill property).
How can this be achieved with the QT-Designer?
Note: I've been playing around with the QTreeViews sizePolicy properties. If these are set to Expanding (as is the default) the accepted answer works out out of the box.
In Qt Designer, right-click the dock-widget, and then select Lay out -> Lay Out Vertically from the menu. Or you can just click on the dock-widget to select it, and then use the equivalent layout toolbar buttons.
If you want to maximise the space taken up by the tree-view, select the first child widget of the dock widget (it will probably be shown as dockWidgetContents in the Object Inspector pane). Then scroll down to the bottom of the Property Editor, and reset all the margins to zero.

I know that I can add option to TinyMCE toolbar to change selection styles using toolbar setting with keyword styleselect. I also know I can adjust the contents of the menu that opens with that button using setting style_formats combined with formats. (Above is correct for version 5.10.2.)
Is there some way to configure the rendering of the styleselect option in the toolbar? I would want to swap the text label to single icon on smaller displays. For big viewports the feature to show the current style at the caret location is a nice feature but for narrow viewports it would be better to have custom icon instead of partial style name in the toolbar.
I'm building my first Universal Windows Platform (UWP) App and am trying to implement the popular "Hamburger Menu" using the SplitView class.
Inspired by many samples, the items hosted on the SplitView pane are re-styled RadioButton controls, with a vertical highlight-rectangle, an icon and a text. The appearance is similar to that of the Groove app.
I'm now trying to implement navigation and selection using the keyboard, and this now bring a little focus-rect around the items in the SplitView pane. However, since the pane clips its contents when its DisplayMode is either CompactInline or CompactOverlay, the focus rectangle is also clipped, which is not the behavior a user would expect.
Please, can anyone advise on how to property display the focus rectangle in this situation ?
Just an idea, what if you set the width of all radio button's to be same as the CompactPaneLength property of SplitView. The default is 48 DIPs.
I have a MFC dialog based application. User can change the language of the dialog, and I made this by closing existing dialog, and opening another with changed language. The problem is that the effect in the taskbar is that one icon is removed, and another identical is created in its place. If my application's icon is not the last icon in the task bar it will be perceived as it was moved to the end of taskbar icon set.
I want to retain icon's position in the taskbar, and rather to prevent icon flicker at all from happening. How do I do that?
The application must support OS'es from Windows XP to Windows 7.
EDIT: alternative question for which I would accept an answer is how to create an invisible window that is nevertheless shown in the taskbar, and how to forward relevant window messages from that window to my main window?
Make the dialog a child of another outer parent window. The parent can be a dialog or any other kind of window; all it will be providing is the title bar. If the user tries to resize it it will have to forward resizing commands to the dialog, but otherwise you shouldn't need to do much in the parent window.
Why not replace the dialog with a CFormView instead? That way there's a frame window that wraps around the dialog (which is embedded in a form view) and it's the frame window that owns the taskbar icon.
Create an SDI application that displays a CFormView. Display the dialog in the default language (or whatever langauge the user previously chose) on initialization. When the user chooses the 'change language' option, simply change the form view that's being displayed with a new one.
Bonus feature: with this design, the framework will take care of things like language-specific accelerators and menus for you with no effort on your part.

I got a menu in an existing MFC application that has a standard MFC main menu.
But I would like to change its background colour so that it appears to more seamlessly belong to the rest of the application.
First picture: An MFC main menu. The application is skinned blue, as seen in the toolbar, but the menu is still standard grey background colour.
Second Picture: Spotify's menu, skinned to fit into the rest of the
colors.
I have not found any examples on anything similar. Could you please point me towards how to achieve this?
Approaches I thought of:
Subclassing CMenu to my own SkinnedMenu, but it is not created by our code but by a GetMenu() call in a mainframe class deriving from CFrameWnd. The only thing I can find here is its method signature, defined in afxwin.h so then how could I make use my own subclassed menu?
Removing the entire menu and add my own custom menu buttons, in a row, making it look like a menu. Maybe this is what spotify have done, as they have also removed the Windows window frame.
Editing the existing CMenu in some way, but the only customization I am able to find right now is modifying its MENUINFO. For example if I set info.hbrBack = skin.GetSysColorBrush(COLOR_MENU) the only colour that changes is the background of the dropdown, not the main menu itself.

I need to create drop down menu (see the picture). What methods are there? What should I use?
LWUIT 1.5 includes a popup dialog which does exactly that. It also has the ability to use an arrow border when specified. See the LWUITDemo's Dialog demo.
Create a class which derives Dialog , and add a List inside that Dialog. When you click the button then show the Dialog with the four params top, bottom, left and right.
To draw the triangle of the drop down menu just implement the paint method when you derive Dialog in which you call :
super.paint(g);
g.drawLine(x1,y1,x2,y2);
g.drawLine(x3,y3,x4,y4);
