[issue15189] tkinter.messagebox does not use the application's icon

[Terry J. Reedy]

Terry J. Reedy added the comment:

After applying the .wm_iconphoto patch, I verifies that the icon specified is used for the options dialog and an ask file name message box opened by the dialog. In other words, dialogs and boxes *do* use the application title bar icon if one is provided. So I consider that existing method to be the feature requested, or at least as much of it as is sensible for tkinter.

Title bar icons are 16x16. Desktop icons are much bigger. While large icons can be scaled down, the result will not necessarily be satisfactory. For instance, the Python console app has separate large and small icons. I claim on #20406 that Idle should also. In any case, automatic cross-platform access to and downscaling of a large desk icon to a small title icon should be done by tk, if at all.
