◆ set_window_icon_name()

bool set_window_icon_name ( TwmWindow * win )

[Re]set a window's icon name.

As with the window name version in set_window_name(), this is mostly separate so the AddWindow() process can call it.

Note: As with TwmWindow::name, we never want to try free()'ing or the like TwmWindow::icon_name.

See also: set_window_name() for details; this is just the icon name equivalent of it.

◆ set_window_name()

bool set_window_name ( TwmWindow * win )

[Re]set a window's name.

This goes over the available naming sources for the window and points the TwmWindow::name at the appropriate one. It may also set a property to signal other EWMH-aware clients when we're naming it a way they can't see themselves.

Note: This should rarely be called directly; apply_window_name() should be used instead. It's split out because we need to do this step individually in AddWindow().; Note also that we never need to worry about freeing the TwmWindow::name; it always points to one of the TwmWindow::names values (which are free'd by the event handler when they change) or to NoName (which is static). So we can just casually flip it around at will.
