…te method. Was crashing when looking for widget.image. Needed to check attr exists first 6.3.5 14-Aud-2026 New feature for window resizing. Added ability to set resizable parameter when creating the window to the normal True/False as well as taking a tuple that indicates the directions the window can be resized (e.g. resizable=(False, True) means only allow resizing in the Y direction.

… also a fix for Wayland (successor to X11). It's a somewhat fundamental change to how every window is created. Rather than using Alpha to hide a window while it's being created, this version withdraws the window and uses a call I didn't know about to get the size of the window before it's fully created. master.winfo_reqwidth() master.winfo_reqheight(). Alpha was needed before so the window dimensions could be gathered to determine where to locate the window so it is centered on the screen.

…ack the alpha method of hiding the window when the window has no titlebar. The withdraw method of hiding the window causes the titlebar to appear so can't use it for no titlebar windows

…window during creation. It's providing an icon on the taskbar that I've not been able to get using previous methods. Still need to change the minimize window code for custom titlebar. Needed to change custom_titlebar_restore in order to show an icon on the titlebar when the window has been restored after minimize. It's Windows specific so need to test all this on Linux & Mac Added function fname() to use as a debugging aid. When printed, it prints the function name of the function the print is inside of. Usage: print(f'[{fname()}] starting...') # → [my_func] starting...
