Detailed Description

Hotkey subsystem.

This file define what's a hotkey. Deals with the low-level XKBlib and Gtk/Gdk.

Definition at line 52 of file hotkey.c.

hotkey_accel_to_code()

void hotkey_accel_to_code	(	const gchar *	accel,
		gint *	code,
		GdkModifierType *	mods
	)

Translate a Gtk Accelerator string to a key code and mods.

Parameters

accel	the accelerator string to parse.
code	the key code returned after parsing.
mods	the key modifiers after parsing.

Definition at line 230 of file hotkey.c.

hotkey_code_to_accel()

gchar* hotkey_code_to_accel	(	guint	code,
		GdkModifierType	mods
	)

Translate a key into a Gtk Accelerator string.

Parameters

code	the key code to process.
mods	the key modifiers to process.

Returns

the accelerator string, must be freed.

Definition at line 208 of file hotkey.c.

hotkey_free()

void hotkey_free

(

Hotkey *

hotkey

)

Ungrab a key and free any resources.

Parameters

hotkey

a Hotkey instance.

Definition at line 160 of file hotkey.c.

hotkey_grab()

gboolean hotkey_grab

(

Hotkey *

hotkey

)

Grab a key manually. Should be paired with a hotkey_ungrab() call.

Parameters

hotkey

a Hotkey instance.

Returns

TRUE on success, FALSE on error.

Definition at line 92 of file hotkey.c.

hotkey_matches()

gboolean hotkey_matches	(	Hotkey *	hotkey,
		guint	code,
		GdkModifierType	mods
	)

Checks if the keycode we got (minus modifiers like numlock/capslock) matches the hotkey. Thus numlock + o will match o.

Parameters

hotkey	a Hotkey instance.
code	the key code to compare against.
mods	the key modifiers to compare against.

Returns

TRUE if there is a match, FALSE otherwise.

Definition at line 138 of file hotkey.c.

hotkey_new()

Hotkey* hotkey_new	(	guint	code,

mods	the key's modifiers.

Returns

the newly created Hotkey instance.

Definition at line 179 of file hotkey.c.
