Min / Max / Restore broken - Ribbon for WPF Forum

Posted 14 years ago by SledgeHammer01

Version: 10.1.0522

Platform: .NET 4.0

Environment: Windows XP (32-bit)

This is on XP with .NET 4.0. 32-bit. Default XP blue theme. Default XP blue theme system metrics.

1) Open Document Editor (like Word) sample -- in external window
2) Switch to blue theme / turn off scenic layout
3) Minimize the window to the task bar
4) Restore the window from the task bar

You'll notice all 4 corners are blackened into squared corners (i.e. the window region is not right).

EDIT: Also happens with scenic layout and all 4 themes you have in the sample app.

When you verify this fix... please also verify for this situation:

public const int SW_RESTORE = 9;

[DllImport("user32.dll")]
private static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

public static void RestoreWindow(Window Wnd)
{
HwndSource hWndSource = (HwndSource)PresentationSource.FromVisual(Wnd);

if (hWndSource != null)
ShowWindow(hWndSource.Handle, SW_RESTORE);
}

We use this function to "un-minimize" a popup window from the taskbar (i.e. a maximized window gets restored maximized, etc). The fix should probably fix both situations since they happen the same way, but you never know :).

Thanks we've fixed this for the next maintenance release. The code to update the clip region was using the Window's WindowState property to ensure it was "Normal" however the Window's property wasn't updated by the time the clip region update method was called. We changed it to use an API call to check window state and that fixed it.
