hi,
i'd like to propose the implementation of
void gtk_accelerator_table_modifier_mask (GtkAcceleratorTable *table,
guint8 modifier_mask);
if an accelerator for e.g. a menu item is bound to
accelerator_key=133 (<- 'q')
accelerator_mods=8 (<- GDK_MOD1_MASK i.e. <Alt>)
it can be invoked by pressing <Alt>-Q and then e.g. quit an application.
i just spend several hours to track down a "bug" because gubi only exited
on <Alt>-Q after i "reinstalled" the accelerator on the selected menu item
by pressing <Alt>-Q.
finaly i found out i had num-lock turned on all the time (harglfn!).
this caused
accelerator_mods=24 (<- GDK_MOD1_MASK | GDK_MOD2_MASK)
stupid me...
if we put add a general mask for the modifiers to each GtkAcceleratorTable
and use it in gtk_accelerator_table_check() to mask out any unneeded
modifiers, <Alt>-Q and else stuff will work regardless of num-lock,
shift-lock and else disturbances.
struct _GtkAcceleratorTable
{
GList *entries[256];
+ guint8 modifier_mask;
gint ref_count;
};
+ void gtk_accelerator_table_modifier_mask (GtkAcceleratorTable *table,
+ guint8 modifier_mask);
i'm not to sure about the modifier_mask being located in each
GtkAcceleratorTable, may be this should be a static variable in
gtkaccelerator.c?
comments, suggestions?
i'll post a patch within 2 or 3 days to the list for one of the solutions
if nobody contradicts.
