Merged
Conversation
Set the WM_CLASS of IDLE's long-lived windows (window-list windows and the stack viewers) to "Idle" instead of the default "Toplevel", so that window managers group and label them correctly.

The root window is created with
Tk(className="Idle"), but IDLE's toplevel windows kept the defaultToplevelWM_CLASS, so X11 window managers (GNOME Shell, KDE) group and label them incorrectly.Set
class_='Idle'on IDLE's long-lived, independently-listed windows so their WM_CLASS matches the root:ListedToplevel(editor, shell, output, class/module/path browsers, debugger);Transient dialogs (Find/Replace, config, About, …) and override-redirect popups (autocomplete, calltip, tooltip) are left unchanged: the former are grouped with their parent via
WM_TRANSIENT_FOR, the latter are not listed by the window manager.🤖 Generated with Claude Code
