Treeviewer select all the elements [message #312954]

Hi,
I would know if it's possible to select all the elements (all the
parents and all the children) in a treeviewer. Because I have tried to
use the following code :
mTreeViewer.getTree().selectAll();
But it seems not working. So there is a solution?

Many thanks in advance.

Hi,
I have used the following code and it works, not sure if there is any
other better solution.

treeView = new CheckboxTreeViewer(cmp, SWT.SINGLE);
treeView.addCheckStateListener(new ICheckStateListener() {

public void checkStateChanged(CheckStateChangedEvent event) {

// If the item is checked . . .

if (event.getChecked()) {

// . . . check all its children

treeView.setSubtreeChecked(event.getElement(), true);

}else {

// . . . uncheck all its children

treeView.setSubtreeChecked(event.getElement(), false);

}

}

});

Have you ensured that your table has been created with the SWT.MULTI
flag? Otherwise the selectAll() method has no effect (as documented).

Yep I forgot to add the SWT.MULTI but I also forgot to add the
expandAll() method on the TreeViewer to have the selection for all the
elements.
Thanks a lot !
