TreeColumn in CheckboxTreeViewer tree

[howieb]

I have two dialogs. The first dialog I had no problem creating this control in the container child of the dialog. In the second dialog I had a TabFolder, and tried to create this in the second TabItem's composite. When I place the column onto the tree, the header appears at a height of 0, and I can't resize it. The only way I can select it is in the tree. Any ideas?

You need to set the headerVisible property to true.

Thanks Eric.

Did I actually write that line of code for the correctly functioning dialog, or had it been generated for me by SWT Designer? I honestly don't remember doing it (and it was just this weekend). I also did not see that property in the designer itself, so it was either generated code or I must have written.

Your either added it yourself or you set the headerVisible property to true in the Designer property pane.

The headerVisible attribute is a property of the CheckBoxTableViewer's underlying (table) control.

See below...

I don't know how I missed that... I was using Tree, not Table, but I see it there now as well.

Thanks.

All of the JFace Viewers have a control attribute which exposes the underlying widget (e.g., a table, a tree, etc.).
