Hi, I noticed a little difference between gtk and win32 in handling window sizing programmatically and appreciate any advice on the subject.
On Windows it is possible to create user-drawn window that formally is not resizable and has no system decoration, but behaves like normal resizable window. So I had BorderStyle = bsNone and custom buttons and my own border for resizing. It was easy because WindowState still responds to wsMaximized in this case and borders can be also responsive by implementing WM_NCHITTEST handler. But both seems to not work on gtk (no visible change for WindowState changing and no visiting both WM_NCHitTest and CM_HITTEST handlers) I can fix the first problem just by little extra code that switches between the current size and Bounds(0, 0, Screen.Width, Screen.Height), but the borders emulation is a harder task (I should track the areas, cursors and window sizing arithmetics, not mentioning that the program doesn't obey the system way of resizing for example frame drawing instead of window drawing). Is there some other solution or maybe setting/option I miss? With Nchittest the question is also does it work at all on gtk? I see that there are plenty of places in lcl so not working for forms look a little strange. Thanks Max
