Detailed Description

Device that selects for core keyboard events.

Member Function Documentation

int Laxkit::CoreXlibKeyboard::eventFilter	(	EventData **	events_ret,
		XEvent *	xev,
		anXWindow *	ww,
		int &	isinput
	)

virtual

This is supposed to translate any device related events to EventData objects. This also means updating any focus and tooltip checks.

Return 1 if event is absorbed, and nothing else should try to parse it. Return 0 for event ignored.

Parameters:

ww	The target window for the event
isinput	Set to 1 if the processed event is input related

Reimplemented from Laxkit::LaxDevice.

int Laxkit::CoreXlibKeyboard::selectForWindow	(	anXWindow *	win,
		unsigned	long
	)

virtual

Return 0 for success. 1 for error.

Selects for key up/down, button up/down, pointer motion, enter/leave, focus change, using core Xlib if ANXWIN_NO_INPUT is not set in win->win_style.

Reimplemented from Laxkit::LaxDevice.

int Laxkit::CoreXlibKeyboard::SetFocus	(	anXWindow *	win,
		clock_t	t,
		int	notifyonly
	)

virtual

Called by anXApp when the focus needs to be set to win.

Return 0 for success. nonzero for error.

For instance, when using core Xlib, XSetInputFocus() would be called from here.

Reimplemented from Laxkit::LaxKeyboard.
