Review request for Dolphin and KDE Usability.


Repository: kde-baseapps


Description
-------

Users suggested in the forum thread http://forum.kde.org/viewtopic.php?f=285&t=121393 that the same shortcut should be used for showing and hiding the filter bar. This patch implements this behavior, and makes the "Show Filter Bar" action a "toggle" action to achieve that.

Ctrl+I now toggles the visibility of the filter bar, and a checkbox is added to the menu to show the current state of that action, see screenshots (the first one shows the current state, and the others the patched version with the filter bar shown/hidden). Additionally, Esc still closes the filter bar. I guess that we might want keep this behavior because some users might have got used to it, and Esc is sort of the standard key to get out of something.

A note on the implementation: I had to add the statement

emit showFilterBarChanged(true);

to the "true" branch in DolphinViewContainer::setFilterBarVisible(bool) to ensure that the state of the action is always consistent with the "visible" state of the filter bar. Without this change, it could become inconsistent in some situations. E.g., when enabling "Show Filter Bar" in the startup section of the settings dialog, the filter bar was shown, but the action was still unchecked.
