Highlighting Tree Item Selection [message #454337]

Is there anyway to control the display of the currently selected item in a
Tree? I have a Tree control that the user can move an item in the tree up
or down. When the item to be moved is first selected with the mouse, the
item is highlighted and is blue in color. After the item is moved, I
would like to have the moved item displayed in the same way (highlighted
and blue). Is there any way to do this? I tried setSelection, showItem,
but neither of these affect the appearance of the item.

Thanks for any help.

Hi,

I tried this too with DND in an SWT Tree and this code worked well for me:

TreeItem newItem = new TreeItem(parent, SWT.NONE, index);

// show selection
tree.showItem(newItem);
tree.setSelection(new TreeItem[]{newItem})

With kind regards
