In one MFC application there is a paned window.
On that window,
I have added a menu-bar and a toolbar and lots of other controls.
The paned window is re-sizable.
Now for the re-sizable window, I have override the function OnSize(). There I have retrieved the top window size and then below it and so on...
Then for every control I have retrieved it's window and called MoveWindow().
I just wants to be assured is it the correct way for handling resizable window/ dialog in MFC or there is some other ways available.
Thanks
Instead of reinventing the wheel: try the ResizableLib.
It can handle resizing of dialogs in a very easy way and you don't have to worry about every detail yourself.
When moving a large number of controls at once, it is preferable to use DeferWindowPos to minimize the repainting. I have an example of how to use it for a resizable MFC dialog at https://stackoverflow.com/a/5739620/5987.

I would like to be able to toggle between framed and frameless window in my Electron app, without needing to construct a new window. This is because this option is a different view than what would be initially loaded, therefore it would be nice if there is a way to change the current window to be frameless.
I have found window.setFullscreen() for toggling between full screen mode. I've not been able to find anything similar for frameless window. Is there any such method or workaround that I'm not seeing?
As the docs go, you enable or disable window frame at the time of creation of browser window. After that, there are no methods you can call to enable or disable frame. However, if you really really want that option, there may be a workaround. And a workaround, is well, a workaround.
Create 2 browser windows, one over the other. The first one being transparent window(with frame and click-through) and the second one being your content window(without frame).
Implement your custom solution to keep size and position of both the windows in sync. Use ipc to share data between the windows.
Toggle the visibility of the transparent browser window to show/hide frame.

I'm laying out UI on a storyboard using the new, controversial library button which has been moved up.
This is driving me crazy - I want to be able to "PIN" this window to a secondary monitor so I can always see available components as opposing to having to click that button every single time I need an element. Currently it disappears, even on secondary monitor once I shift focus to the view controller on screen.
How do I pin the UI Elements library to be able to always see it ?
You can press the option button in keyboard and click in the library window, it's will hold

I would like to make sure that no widget in a jface Dialog is ever disappearing.
Scrollability would be an easy solution, but I would prefer a resizable window that is always at least as large as to display all contents. Do you know of any setting to enable this functionality?
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 am trying to create a dockable window in Qt (it sits taking 4px width at the edge of the screen, always on top and it slides out when you hover it). I have to use WindowFlag BypassX11WindowManager (in order to hide taskbar hint, disable moving/resizing/etc. from window manager). I use these flags:
Qt::FramelessWindowHint
Qt::CustomizeWindowHint
Qt::X11BypassWindowManagerHint
Qt::WindowStaysOnTopHint
When I need my dock to be activated, I use the activateWindow() method. However, I have no idea, how to deactivate it.
Is there a way I can force my window deactivate? Now I can do it only by clicking another window and then return to the one that was active before revealing dock.
You should be able to use ->hide() to simply hide it if you don't want it to appear at certain points.
I assume, by the way, you know there is QDockWidget/ class that may help you as well. It's unclear from the above if you're using it or not.
