Function accelerator_parse 

Source 
pub fn accelerator_parse(
    accelerator: impl IntoGStr,
) -> Option<(Key, ModifierType)>
Expand description

Parses a string representing an accelerator.

The format looks like “<Control>a” or “<Shift><Alt>F1”.

The parser is fairly liberal and allows lower or upper case, and also abbreviations such as “<Ctl>” and “<Ctrl>”.

Key names are parsed using keyval_from_name(). For character keys the name is not the symbol, but the lowercase name, e.g. one would use “<Ctrl>minus” instead of “<Ctrl>-”.

Modifiers are enclosed in angular brackets <>, and match the gdk::ModifierType mask:

  • <Shift> for GDK_SHIFT_MASK
  • <Ctrl> for GDK_CONTROL_MASK
  • <Alt> for GDK_ALT_MASK
  • <Meta> for GDK_META_MASK
  • <Super> for GDK_SUPER_MASK
  • <Hyper> for GDK_HYPER_MASK

If the parse operation fails, @accelerator_key and @accelerator_mods will be set to 0 (zero).
