Remove size gadget

Is there any system-friendly way to turn off the resize gadget _after_ the window has been created? It seems, that SetWidowAttrs(window, WA_SizeGadget, ...) doesn't work...

I don't think you can remove the rezise gadget (or any system gadget) whilst the window is open.

If you don't want a resize gadget then you must specify that at open time.

The problem is, that Qt wants to calculate the min and max dimensions after the window has been opened. Well, I guess I have to try and change that...

I'm afraid not. When using ReAction (= window.class-based) windows) you'd have to

- close or iconify the window
- change the attribute via SetAttrs()
- reopen or de-iconify the window

This is possible because WM_CLOSE or WM_ICONIFY closes the window without disposing of the object. But I guess you can't apply such a trick with the oldstyle Intuition windows.

@alfkil
Seems you have two options:
1. Delay opening of the Intuition window until some time after QT would normally do so. This is not necessarily a problem if it will happen only a few QT calls later.
2. Close & re-open the Intuition window.

iirc it is possible to create a window avoiding to show it and then open it with ShowWindow. I don't know if it could work and i have no autodocs here but could be a solution

Reading the autdocs for hidewindow and showwindow, they seem to imply thewindow is still "open" just hidden, thus you cannot mess with it's gadgets etc.
