When a Winform with WPF UserControl added is displayed in an MDI window, the size cannot be changed.

Please confirm.

I am sorry but I am not an expert on WinForms and this question is also not related to 3D graphics but is a general question on how to use WPF in WinForms.

I would recommend checking other sources on internet or asking question on stackoverflow.com.

If you would use WPF, then for having multi-window application I would recommend using AvalonDock (https://github.com/Dirkster99/AvalonDock...me-ov-file)

I thought wrong.
The problem occurred because the Dock option was given after creating the form and Show()ing it.

It was resolved by disabling the Dock option.
