XAML island : How to customize title bar

Harshithraj1871 1,496

Hi,

I'm working on a window desktop application in win32(C++ desktop (Win32) app) and I'm Hosting a standard WinRT XAML control in it.

As I understood, we can use xaml island on particular area of the window. But can we use it customize the title bar? I wanted to make a custom title bar like this, this example in done using WinUI3 title bar customization .

User's image

can we do this in Win32 desktop application with xaml island? Or should i use Win32 Title bar customization?

Thank You

In Win32 Desktop apps, it is done with DWM : Custom Window Frame Using DWM

Thank you for the response @Castorix31 , I tried this with xaml island but facing some issues. Custom Window Frame Using DWM extends the client area to whole window. And i want to set xaml island to the whole window like this(below example used winui3) -

When we set xaml island to the whole window, Xaml island will be placed on top of win32 controls (min, max close also) like this -

and we cant capture WM_NCHITTEST also.

How to solve title bar customization in this case?

@Castorix31 , when we follow this should we handle Min, Max and close button ourself? because after removing the standard frame Min, Max and close buttons are not working

Can you get WM_SIZE message in WindowProc?

You can try to handle this WM_SIZE message by yourself.
