How to resize a window from every edge/border?

Hello everyone,

hope someone can help me. If you habe a windwo (widget/dialog) then you can resize this window by dragging the QSizeGrip in the lower-right corner. Is it somehow possible to resize the window by dragging the edges/border of the window?


Kind regards,
xinor


Edit
Ok, looks like on Windows and Linux you can do that by default.
Is it somehow possible to activate it for Mac too?

It's strictly an operating system issue. You need to find a system-wide solution, not an application-wide.
