How to set a window not sizable?

[fredvs]

MinHeight := 100; works, when resizing the minimum height is blocked to 100.
But with MaxHeight := 100; does not work, resizing height > 100 is possible (with garbage in the height > 100) .

How to avoid resizing?

Hello Fred. It's the Sizeable property.

procedure TMainForm.AfterCreate;
begin
  Sizeable := FALSE;

That property is like a on/off switch, it's all or nothing. Min[width|height] and Max[width|height] is a constraint. The latter allows resizing, but only up to a certain size.

Thanks Fred for reporting it. Their was a timing issue, of when the resizing restriction must take effect. It should be fixed in develop, as commit 47aebe2 fixed it for x11 and cocoa backends.
