listbox doesn't have selected column you can only get selected row. If you need selected column you have to have a control (button, image etc..) and let the user click on the control. That will give you an idea on which column they clicked.

Hi, meilynlgg
I write a sample

		 void showColumn(Listcell listcell){
			 Listitem item = listbox.getSelectedItem();
			 int index = item.getChildren().indexOf(listcell);
			 Listheader listheader = (Listheader)listbox.getListhead().getChildren().get(index);
	<listbox id="listbox" width="200px">
			<listheader label="col1" />
			<listheader label="col2" />
			<listcell label="a1" onClick="showColumn(self)"/>
			<listcell label="a2" onClick="showColumn(self)"/>
			<listcell label="b1" onClick="showColumn(self)" />
			<listcell label="b2" onClick="showColumn(self)"/>

It works on ZK 3.6.X
it will happen NPE on ZK 5.X
because this bug
we will fix it
