I don't see what you mean. Removing WS_THICKFRAME removes sizing borders. Then I can add a Border to use Pointer events to move the window :

WinUI3_NoCaption

@castorix I mean that after remove WS_THICKFRAME, I can't receive WM_NCHITTEST

I see that winui create a child window, may be this child window covered whole hwnd which be register wndproc?

Do you have any suggestion?

Microsoft.UI.Content.ContentWindowSiteBridge class is the Composition window which draws XAML But what do you want to do with WM_NCHITTEST ?

TrungTHT commented 2 years ago

@castorix I want to use it to custom titlebar, because ExtentContentTitleBar can not hide some caption buttons. I just see that next version can resolve it 😁

Hope that we can get new version early
