Problem with TableTreeViewer and CheckboxTreeViewer -- HELP NEEDED! [message #463758] Mon, 14 November 2005 14:59 Go to next message

Hi,
I have created a checked box table tree using
checkboxTableTreeViewer = new TableTreeViewer(parent, SWT.CHECK);
and have associated a table tree editor like
........
final TableTreeEditor tableTreeEditor = new TableTreeEditor(tableTree);
........

this works fine but now I want to listen for check event of the checked tree
?
How can I do this ?
I tried
CheckboxTreeViewer checkboxTreeViewer = new CheckboxTreeViewer(
checkboxTableTreeViewer.getTableTree());
checkboxTreeViewer.addCheckStateListener(new
CheckboxTreeViewerCheckStateChanged());

But the control never comes to CheckboxTreeViewerCheckStateChanged class
(function checkStateChanged )

Am I doing wrong ?
what's the correct way to create such a control ?
Thanks in advance

Since you created the underlying tree with the SWT.CHCK style you should use
Tree.addSelectionListener() and in the event.detail look for SWT.CHECK
to distinguish the checkbox selection from selecting the row.

Thanks !
I did that
But now i have one more problem !
The tree i created looks good on windows 2K
but does not look proper on Linux Fedora core 3
I means on fedora the nodes at verious levels of tree should get indented to
right. The tree hirarchy should get clear.
I m attaching the sample pic.
See that node1 has child node2 which has also a child node3
The relation between node1 and node2 does not get seen properly wheare as
the relation between node2 and node3 is clear deu to indentation !

Any clue ?

Thanks
~Preetam

This is a known problem on GTK - indentation is not supported. This is why
in 3.1 we deprecated TableTree and added support for Tree with TreeColumn.

See:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet170.java?rev=HEAD& amp;content-type=text/vnd.viewcvs-markup

TreeViewer also supports TreeColumn.
