Re: [Java-gnome-developer] Strange error mesage when using treeView

[Kyrre N. S. <ky...@so...>]

Yeah, i found out. Annother angel on the list was at my mailbox before
you :)

I changed the code to:
	private void setupTreeView () {
		//Setup the backend storage
		//DataColumn[] columns = new DataColumnString[1];
		datacolumn0 = new DataColumnString ();
		channellist = new ListStore(new DataColumn[] {datacolumn0});
		channellistWidget.setModel(channellist);
		
		//Setup the visual appearance of the treeView
		TreeViewColumn col0 = new TreeViewColumn ();
			CellRendererText render0 = new CellRendererText ();
			col0.packStart(render0, true);
			col0.setTitle("Channel name");
			col0.addAttributeMapping(render0, CellRendererText.Attribute.TEXT,
datacolumn0);
		
		channellistWidget.appendColumn(col0);
		
		//General setup of the widget
		channellistWidget.setEnableSearch(true);
		channellistWidget.setAlternateRowColor(true);
		channellistWidget.setHeadersVisible(false);
		
	}

And now it works :)
