set_transient_for_exported
Description:
Marks this as transient for the surface to which the given parent_handle_str refers.
Typically, the handle will originate from a [method@GdkWayland.WaylandToplevel.export_handle] call in another process.
Note that this API depends on an unstable Wayland protocol, and thus may require changes in the future.
Parameters:
| this |
the `GdkToplevel` to make as transient |
| parent_handle_str |
an exported handle for a surface |
Returns:
|
true if the surface has been marked as transient, false if an error occurred. |
