Issues with Tree #37
Description
I noticed some issues with the Tree implementation:
- There seems to be some ordering of tree items that should not be applied.
- The tree items show icons where there shouldn't be any.
To see the difference, here is the native SWT version
And here the SWT Evolve version
The ordering issue is actually not really visible, as there is an issue with the layout rendering, so the tree content is not really visible. But the Classic Examples should be the second entry on top level, but it is the first entry in SWT Evolve. I also noticed this when trying to select the examples in the deeper levels, which are not in the expected order but somehow ordered in alpabetical/natural order.
