gdk-keymap-add-virtual-modifiers (keymap state)

keymap -- a gdk-keymap object
state -- a value of the gdk-modifier-type flags

The gdk-modfier-type flags.

Adds virtual modifiers (i.e. Super, Hyper and Meta) which correspond to the real modifiers (i.e. Mod2, Mod3, ...) in modifiers and set the corresponding bits in state.

GDK already does this before delivering key events, but for compatibility reasons, it only sets the first virtual modifier it finds, whereas this function sets all matching virtual modifiers.

This function is useful when matching key events against accelerators.
