I am creating a stacked widget, and want to have each widget have its own titlebar. I am adding the stacked widget to a preexisting layout. For some reason none of my stacked widgets have any sort of titlebar or window at all, just a blank space. I see many posts online on how to get rid of titlebars using setWindowFlags(), but not how to add one.
The title bar is a feature that's only added to top-level widgets, also called windows, by the platform's window manager. It's not something that Qt adds or can make appear within a window itself.
You'll need to add the tile bar using a QLabel or a similar widget.

I am trying to use the new FlyoutPage. I have set my Detail and Flyout pages.. now I want to customize the bar (with the hamburger menu), for both iOS and Android.
I need to change colors and add buttons etc.. Is there a way to do that with Xamarin.Forms (without using shell..) ? Or is there at least a sample of how to effectively do that with custom renderers?
I have tried to change the theme in my Android project to make changes, but with no great success.
Last but not least, could I remove the bar to create my own from scratch (but of course keep the flyout) ?
The bar I want to remove
I have a small problem whit QScrollbar.

This is a one my project in C#
At left panel, the user loads a graphic image and can pick elements.
but I see in Qt don't exist Split Panel whit automatic Scrollbar.
I tried to use QScrollArea, but if user maximizes Window it's a problem.
anyone have a solution or a good way to make this in qt?
I'm a beginner of JavaFX. Is there anyway to change the color of title bar. I just want to make the application all black. I have searched the JavaFX API, but I can't find any method to make it.
This is pretty much an OS dependent thing. The operating system gets to decide how titlebars and borders are displayed by default. However, it definitely can be done, if you are willing to venture into making your own title bar.
To start out, you will need to modify the application window's stage to StageStyle.UNDECORATED. Then you will need to set up your own borders and title bar (complete with things like the title, minimize button, close button, etc.). You can then add the border pane as a scene into your application's stage, and that should render your custom titlebar then without the default Windows styling.
You can find an example implementation of that here: https://stackoverflow.com/a/9864496/2694511
Do note that because you are implementing your own titlebar, you will also lose the OS's default window drag behavior, so you will need to implement your own window-drag/window-move code. This answer might be able to help you with that: https://stackoverflow.com/a/11781291/2694511
I'm reading Qt Designer manual. And found following para saying;
"Qt Designer provides a scratch pad feature that allows you to collect
frequently used objects in a separate category. The scratch pad
category can be filled with any widget currently displayed in a form
by dragging them from the form and dropping them onto the widget box.
These widgets can be used in the same way as any other widgets, but
they can also contain child widgets. Open a context menu over a widget
to change its name or remove it from the scratch pad."
I was searched for scratch pad, but nothing found.
Try dragging a widget (it can have nested child widgets in) from the form editor onto the list of stock widgets on the left, it should add the dragged widget into a new subgroup "Scratchpad". The scratch pad will only appear then.
The scratch pad category can be filled with any widget currently
displayed in a form by dragging them from the form and dropping them
onto the widget box.
It is a little ambiguous, but by "widget box" they mean this guy:
I made a window using QMainWindow with Qt::CustomizeWindowHint flag to remove title bar.
I made a new title bar using my customized widget and implemented window move function.
So my window widget does not work with aero-snap on moving window.
(And my window doesn't work with aero-snap on resizing window)
How can I use aero snap with my customized widget?
Or do you know the apis of aero snap?
I found some web pages related to aero snap apis, but they say about c# only
What is the Aero function for previewing the screen state behind a window?
How can I use the functions on C++?
thanks.
Aero Snap can't be achieved when using CustomizeWindowHint to remove the title bar.
The title bar comes with implicit functionality that is controlled by the window manager, and this functionality includes some of the things you might have already noticed as missing: minimize, maximize, resize, move, system menu, etc.
Removing the title bar is essentially removing any native window manager support, and you're required to implement these features yourself.
