 Posted: Mon Sep 26, 2005 3:51 pm Post subject: Keyboard navigation (documentation) |
 |
|
I know there is basic keyboard navigation in the newer versions of VirtualTree, but it would be nice to have some documentation of exactly what features exist where!
Along the way, pageup/pagedown, row expand/collapse behaviour etc. have been added, but before then I had implemented it myself. Now I have problems getting everything to work as intended because some parts I still have to do myself. And it is rather weird suddenly finding out by coincidence that some of the functionality I have implemented myself is now standard 
Specifically, I would like the row expand/collapse behaviour to be extended so that left arrow (and/or backspace) will jump to parent if selected row is already collapsed. As of 2.0.4, ProcessNormalCmdKeys returns true when the selected row is collapsed using left arrow, but also if no action is taken because the row is already collapsed! This makes it rather difficult for me to implement this myself.
Another nice-to-have feature is home/end navigation.
Oh, and something weird happens when I hold down ctrl while pressing up/down, followed by up/down without ctrl. It looks like the selection is moved while holding ctrl, but this is not displayed.
Sorry about this rather unstructured post  |

We will add a section in help on runtime usage of VirtualTree to document what can be done at runtime in the next release.
We will also look at implementing your other suggested keyboard behaviour.
Holding the control key down while selecting allows you to move the focus row without changing selection - however there appears to be a bug which means the focus indicator is not being repainted in this case. We will fix this in the next release also.

The issue with Control Up/Down nagivation has been fixed in Version 2.1.0 which also includes a section in the help documenting the keyboard navigation keys ("Using Virtual Tree at Runtime")

| And I can see that now I can delete all of my own navigation handling, which is now default |
