Hi,
I am using a StackPanel (called leftStackPanel in code) in my
application and in order to respond to Click events on this stack
panel, I have coded the following and it works fine. But classes
SourcesChangeEvents, ChangeListenerCollection, and ChangeListener are
deprecated. I tried to use alternative new classes like
HasChangeHandlers instead, but I wasn't able to code this with new
classes. Can anyone help me with this?
StackPanel leftStackPanel = new LeftStackPanel();
StackPanelListener stackListener = new StackPanelListener();
leftStackPanel.addChangeListener(stackListener);
//inner class
class LeftStackPanel extends StackPanel implements
SourcesChangeEvents{
ChangeListenerCollection clc;
int current;
public LeftStackPanel(){
clc = new ChangeListenerCollection();
}
public void showStack( int index ) {
int visibleStack = index;
int oldVisibleStack = visibleStack;
super.showStack(index);
if (oldVisibleStack != visibleStack clc != null)
{
clc.fireChange(this);
}
super.showStack( index );
current = index;
clc.fireChange( this );
}
public int getCurrent() {
return current;
}
@Override
public void addChangeListener(ChangeListener cl) {
// TODO Auto-generated method stub
clc.add( cl );
}
@Override
public void removeChangeListener(ChangeListener cl) {
// TODO Auto-generated method stub
clc.remove( cl );
}
/*public void onBrowserEvent(Event event){
super.onBrowserEvent(event);
//if(event.)
if (event.getTypeInt()== event.ONCLICK){
int selectedIndex = this.getSelectedIndex();
}
}*/
}
//inner class
class StackPanelListener implements ChangeListener{
@Override
public void onChange(Widget sender) {
int current = ((LeftStackPanel)sender).getCurrent();
System.out.println(index: + current);
}
}
