Checkbox being checked is not registered if text is empty

[PierreYvesH]

Hi, so if I create a form and add a checkbox chkbx = widgets.checkbox( form, "", center=True, var=var) Then when I check it while running, its value never changes because the variable l_val is empty. An easy fix would be to append widget.checked instead of widget.text line 218.
