Bounded mouse position when moving child form

[LionAM]

Still another question: I want to create a .NET equivalent to the MFC CDialogBar. When I move a form which is a child of a panel, the mouse position is bounded by the panel, even if I set

Parent = nullptr;
TopLevel = true;

on first Move-Event and even if the panel is not visible any more. Is there a workaround? Alex

Hello! For the mouse, I found a solution: The allowed mouse position is bounded by the Cursor->Clip property. But still the window can not be moved completely out of the panel, it stops at the border. Alex

Ok, nearly solved. When I override the WndProc-Method and process the WM_SYSCOMMAND(SC_MOVE) Message, I can reset the Parent-property and the window is not bounded any more. Alex
