Raw key events and rTree

Post by jameshale » Wed Feb 05, 2014 6:32 am

In a V1 rTree one could assign the focus to the rTree and then respond to arrow keys (on the keyboard) and move around the tree.

V2 of rTree is now a "group"rather than a control and the focus command no longer wants to work, telling me the object is of an invalid type.
I tried focussing on the background field within the rTree group but this didn't work.

Ideas?

James

Hi James!

Try setting the "tabGroupBehavior" of the rTree group to false. V2 has arrow key navigation built in and it should work "out of the box" if you set "tabGroupBehavior" to false.

All the best

But how do I keep the focus in the tree?
Well, how do I get it there to begin with?

James,

You should be able to focus the "BackgroundField" as you suggested.

Code: Select all

focus fld "BackgroundField" of grp "rTree"
Does that work for you?

Best
