alsamixer: show channel names for multichannel controls For multichannel mixer controls, add the channel name to each screen control. Also make some other small changes. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> 2009-05-25 10:26:22 +02:00			`#ifndef MIXER_WIDGET_H_INCLUDED`

alsamixer: Replaced hardcoded keys by binding arrays This commit is a preparation for making keybindings configurable. The hardcoded keys in the switch statements of mixer_widget.c, textbox.c, proc_files.c and card_select.c have been replaced by command enums. The command that shall be executed is looked up in the arrays `mixer_bindings` and `textbox_bindings`. The channel_mask enum has been made public, since LEFT and RIGHT are used as command arguments in bindings.c.

alsamixer: fix handling of removed controls When we get a notification that an element has been removed, we have to recreate our internal control representation to avoid accessing freed memory. (And the checking for SND_CTL_EVENT_MASK_REMOVE should actually be done correctly while we're at it.)

alsamixer: added mouse support Mouse support has been added for mixer_widget.c, card_select.c and proc_files.c. In the mixer widget the mouse is handled as follows: - After an element has been printed in mixer_display.c, a call to clickable_set() will store the coordinates of the drawn area plus the command enum that should be executed on click. An optional argument holds an index which points to the selected mixer control. - on_mouse_click() searches for a matching rectangle, focuses the mixer control and returns the command enum. In the menu widgets, the menu_driver() function handles mouse input.
