In 10.6 Apple removed the private QL API that existed in 10.5 and added a new public API. However they did not port the new API back to 10.5 so we have to do some work to get it working in both.
This patch has GitX choose the correct version at run time.
- The delegate code is based on Apple's QuickLookDownloader example project
- added three of the public API methods to CWQuickLook.h to avoid warnings about unknown method calls
- In ApplicationController try to load the public API first then load the private one if it fails
- Created PBQLTextView, a subclass of NSTextView to allow the space key event to toggle the preview panel
- PBGitHistoryView.xib:
- set the text view's class to PBQLTextView
- connected the history controller to the controller outlet
- bound the quick look button's enabled binding to File's Owner.selectedCommitDetailsIndex
- added "Quick Look" to the quick look button's tooltip
- The commit list table view toggles the panel if the tree view is active
- changed name of the toggle IBAction method which caused MainMenu.xib and PBGitHistoryView.xib to update
This allows us to differentiate between one or multiple files,
and will also come in use when we want to create a context menu
from the webview later on
We now use representedObjects to store the selected paths.
That should make it possible to reuse the menu's from somewhere else.
Subclasses NSOutlineView to PBQLOutlineView that takes a controller which
should respond to toggleQuickLook:. This is used for our tree walker to
actually show QuickLook when space is pressed.
