I have a set of qx.ui.menu.RadioButton objects. Which one of them is
selected I want to be dependent on a given property. So I use
databinding ala:
var stateCheck = function(desired) {
return {converter: function(state) {return state == desired}}};
controller.addTarget(button1, 'value', 'state', false, stateCheck(0));
controller.addTarget(button2, 'value', 'state', false, stateCheck(1));
The problem with this is that the RadioButton takes it upon itself to
change it's own value upon being clicked. If I want to control this
behaviour, for example ask the user to confirm the state change. The
problem really extends beyond databinding.
I currently use the following workaround:
function DataBoundRadioButton(label) {
var button = new qx.ui.menu.RadioButton(label);
// Do not manually change the checked state.
button.removeListener('execute', button._onExecute, button);
return button;
}
I think the way I have seen this done in other UI frameworks is that
each menu item has the ability to be checked or unchecked, and that a
RadioButton class would then implement the toggling logic - which would
allow people who want manual control to just use the regular buttons.
