[issue45447] IDLE: Support syntax highlighting for .pyi stub files

[Alex Waygood]

Alex Waygood <Alex.Waygood at Gmail.com> added the comment:

It looks like support for .py files is hardcoded into IDLE's source code in the following places:


* browser.ModuleBrowserTreeItem.OnDoubleClick
* browser.ModuleBrowserTreeItem.IsExpandable
* browser.ModuleBrowserTreeItem.listchildren
* editor.ispythonsource  << This is the one that controls syntax highlighting
* iomenu.IOBinding.filetypes


If I were to file a PR adding support for .pyi files, would you prefer that I hardcoded ".pyi" in, or would it be better to add a SUPPORTED_FILES constant somewhere?
