/* This exists to allow us to override the way GTK handles
key events. The normal sequence is:
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
+ 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
+ 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
it does allow.
