433 a) event is delivered to a GtkWindow
434 b) accelerators/mnemonics are activated
435 c) if (b) didn't handle the event, propagate to
436 the focus widget and/or focus chain
438 The problem with this is that if the accelerators include
439 keys without modifiers, such as the space bar or the
440 letter "e", then pressing the key while typing into
441 a text entry widget results in the accelerator being
442 activated, instead of the desired letter appearing
445 There is no good way of fixing this, but this
446 represents a compromise. The idea is that
447 key events involving modifiers (not Shift)
448 get routed into the activation pathway first, then
449 get propagated to the focus widget if necessary.
451 If the key event doesn't involve modifiers,
452 we deliver to the focus widget first, thus allowing
453 it to get "normal text" without interference
456 Of course, this can also be problematic: if there
457 is a widget with focus, then it will swallow
458 all "normal text" accelerators.
