Currently the galleries in Xara LX are stealing events that should
be processed by the main window. Eg. Using the layer gallery (docked or
undocked), click somewhere in the layer gallery window and then hit a function
key to try and switch tools. Nothing happens. Or use the arrow keys to nudge
your selected object. Again, nothing happens. I believe focus handling took a long time to get right in
the Windows version originally (and in fact it’s not perfect today).
Presumably the correct behaviour is that the window with focus should process
all events that are meaningful to it and pass all others on. So if the layer
gallery for example doesn’t do anything with function key events (as it
shouldn’t) it should pass them on so that tool selection still works. Using this model we should end up with something better than
the Windows version. Eg. Right now if you try and use the arrow keys to move up
and down the font list in the Xtreme font gallery, nothing happens in the
gallery and your selected object gets moved! In this case the font gallery
should process the up/down arrow events itself if it has focus. The fact the new galleries aren’t working in this way in
LX implies that we’re not getting this ‘pass on unused events’
behaviour by default. All non-modal windows should work this way, so do we need
to do some work at the framework level to make it happen? Or is this something
that needs to be implemented on a window by window basis? Neil |
