This change introduces derived classes for ComboButton, DropDownButton
and Select that make sure that buttons do not remain focused after their
menus are closed. This allows using hotkeys after closing them.
Since making use of keypress in addition to keydown, hotkeys did not
work in certain scenarios, including clicking on the feed tree expanders
or empty spaces of the toolbar.
This issue is caused by dijit.Tree and dijit.Toolbar implementing the
_KeyNavMixin, which explicitly stops propagation of keypress events.
This change contains two main fixes plus a smaller hotfix:
1. It overrides _onContainerKeydown and _onContainerKeypress for
fox.FeedTree (which inherits from dijit.Tree).
2. It adds fox.Toolbar, which overrides _onContainerKeydown,
_onContainerKeypress and focus. This fixes hotkeys being swallowed
and the first focusable child receiving focus when clicking on an
empty space of the toolbar.
3. It adds the same handling of keydown and keypress to the prefs hotkey
handler as is done in the main hotkey handler.
keydown returns the "raw" key in event.which. Depending on the keyboard
layout, this may not be what is wanted. For example, on a German
keyboard, Shift+7 has to be pressed to get a slash. However, event.which
will be 55, which corresponds to "7". In the keypress event, however,
event.which will be 47, which corresponds to "/".
Sadly, several important keys (such as escape and the arrow keys) do not
trigger a keypress event. Therefore, they have to be handled using a
keydown event.
This change refactors the hotkey support to make use of keypress events
whenever possible. This will make hotkeys work regardless of the user's
keyboard layout. Escape and arrow keys are still handled via keydown
events.
There should be only one change in behavior: I could not make Ctrl+/
work and therefore rebound the help dialog to "?".
