* @accelerator_mods: return location for accelerator modifier mask
|

*
|

|
* Parses a string representing a virtual accelerator. The format
|
||
|
|
* looks like "<Control>a" or "<Shift><Alt>F1" or
|
||
|
|
* "<Release>z" (the last one is for key release). The parser
|
||
|
|
* is fairly liberal and allows lower or upper case, and also
|
||
|
|
* abbreviations such as "<Ctl>" and "<Ctrl>".
|
||
|
|
*
|
||
|
|
* If the parse fails, @accelerator_key and @accelerator_mods will
|
||
|
|
* be set to 0 (zero) and %FALSE will be returned. If the string contains
|
||
|
|
* only modifiers, @accelerator_key will be set to 0 but %TRUE will be
|
||
|
|
* returned.
|
||
|
|
*
|
||
|
|
* The virtual vs. concrete accelerator distinction is a relic of
|
||
|
|
* how the X Window System works; there are modifiers Mod2-Mod5 that
|
||
|
|
* can represent various keyboard keys (numlock, meta, hyper, etc.),
|
||
|
|
* the virtual modifier represents the keyboard key, the concrete
|
||
|
|
* modifier the actual Mod2-Mod5 bits in the key press event.
|
||
|
|
*
|
||
|
|
* Returns: %TRUE on success.
