set_modal

Description:

public void set_modal (bool modal)

Sets the toplevel to be modal.

The application can use this hint to tell the window manager that a certain surface has modal behaviour. The window manager can use this information to handle modal surfaces in a special way.

You should only use this on surfaces for which you have previously called [method@Gdk.Toplevel.set_transient_for].

Parameters:

this	a `GdkToplevel`
modal	true if the surface is modal, false otherwise.
