Getting TreeViewer object from a CTabItem [message #537026]

Hi all,

I have a TreeViewer that's added inside a CTabFolder here.

private void addTree(CTabItem tab) {

TreeViewer viewer = new TreeViewer(tab.getParent(), SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.VIRTUAL);

tab.setControl(viewer.getControl());
}

There are a few CTabFolder objects created, and I'd like to get the TreeViewer object that's currently active underneath that CTabFolder. Any idea how I could get this? Thank you in advance..

Hi,

You could get the TreeViewer's underlying Tree control by iterating through
the CTabFolder's children (getChildren()) recursively looking for a child
with instanceof Tree. To map this Tree to its TreeViewer I think you would
need to set up a mapping in advance (eg.- treeInstance.setData(someKey,
treeViewer) at creation time). Alternatively, if each CTabFolder only has
one TreeViewer then you could just do this setData(someKey, treeViewer) on
the CTabFolder instead.

HTH,
Grant

Hi Grant,

Sorry for the late reply. Just got a chance to look into this again. Thanks a lot for the suggestion. Managed to get the TreeViewer selected now. =)

Cheers,
