Hi Martin,
I have created an example for my situation (code snippet was attached
to this mail ), when you run this code it will create a screen with
two part including : Tree virtual on the left and sample text on the
right. Follow this path on the tree virtual:
Desktop\Workspace\Windows, the horizontal scroll bar of tree virtual
does not appear although there is not enough space to show the full
text of Windows node label.
Please let me know if you need more information, thanks so much for
your supporting.
Thanks
Khoa Tran
