/* This exists to allow us to override the way GTK handles
|
|
key events. The normal sequence is:
|
|
|
|
a) event is delivered to a GtkWindow
|
|
b) accelerators/mnemonics are activated
|
|
c) if (b) didn't handle the event, propagate to
|
|
the focus widget and/or focus chain
|
|
|
|
The problem with this is that if the accelerators include
|
|
keys without modifiers, such as the space bar or the
|
|
letter "e", then pressing the key while typing into
|
|
a text entry widget results in the accelerator being
|
|
activated, instead of the desired letter appearing
|
|
in the text entry.
|
|
|
|
There is no good way of fixing this, but this
|
|
represents a compromise. The idea is that
|
|
key events involving modifiers (not Shift)
|
|
get routed into the activation pathway first, then
|
|
get propagated to the focus widget if necessary.
|
|
|
|
If the key event doesn't involve modifiers,
|
|
we deliver to the focus widget first, thus allowing
|
|
it to get "normal text" without interference
|
|
from acceleration.
|
|
|
|
Of course, this can also be problematic: if there
|
|
is a widget with focus, then it will swallow
|
|
all "normal text" accelerators.
