  • 0

I am trying to hide hierarchical dotted lines for SWT Tree view.

SWT Tree with hierarchical dotted lines on Windows

How do I hide these dotted lines? Is there any special options?
What is the best and correct way to do it?

I found that with TableTree it is possible to do that – in this example:

http://www.java2s.com/Code/Java/SWT-JFace-Eclipse/DemonstratesTableTreeTableTree.htm

I would use TableTree – but it’s deprecated now.

UPDATE

Found that I can use SWT.FULL_SELECTION option and the lines now hidden.

SWT Tree with disabled dotted lines using SWT.FULL_SELECTION

Now the question is what does this option mean and why we getting hidden lines – will it work for all Windows versions?

    The SWT.FULL_SELECTION should be used when creating the Tree. The result of it is exactly what’s needed – there is no hierarchical dotted lines in full selection mode.
