Hello,

In our RCP application we are creating tree in grid by GridTreeViewer. And
i need a help in expanding or collapsing the tree on pressing of arrow key
left and right. For double click and enter key pressed i am listening and
expanding/collapsing accordingly. But for arrow key i think
tree/treeviewer gives this behavior by default, isn't it? But its not
working like that. So can anyone guide me here?

Regards,
Supreetha H R
