SimpleComboBox question

[TheBuzzer]

How do i catch changes of the field for simple combo box?


I tried using



orderstatus.addListener(Events.Change, changelistener);

Listener changelistener = new Listener<FieldEvent>() {

public void handleEvent(FieldEvent be) {

if (be.field == orderstatus) {
orderdata.setOrderStatus((String) orderstatus.getSimpleValue());
Window.alert((String) orderstatus.getSimpleValue());
}
}
};


this does not catch change for it.

What was I suppose to use?

[gslender]

// combo actions
combo.addSelectionChangedListener(new SelectionChangedListener<SimpleComboValue<ChartType>>(){
public void selectionChanged(SelectionChangedEvent<SimpleComboValue<ChartType>> se) {
switch (se.getSelectedItem().getValue())
{
case BARCHART:
chart1.setModelChartProvider(bcp);
break;

case PIECHART:
chart1.setModelChartProvider(pcp);
break;
}
}});

how do i catch the event if the event is caused by change in the textfield and not because of the drop list change?

for stuff without force selection?

seems like i got to override onblur and make it fire a changeevent.

well if you want to fire an event when ever a text field receives focus you can try the focus event, else you can try the Change event which is fired when ever the text in the textfield is changed. or edited.
