Oh, sure. Here's one that should work:
import <relevant classes like Button, clickhandler, Window>
Button[] myButtons = new Button[2];
myButtons[0] = new Button("clickMeButton");
myButtons[1] = new Button("clickMe2");
for(int i=0;i<2;i++){
myButtons[i].addClickHandler(new ClickHandler(){
Button sourceButton;
@Override
public void onClick(ClickEvent event) {
sourceButton = (Button)event.getSource();
if(sourceButton.getText().equals("clickMeButton")) {
Window.alert("works");
}
if(sourceButton.getText().equals("clickMe2")){
Window.alert("works2");
}
}
});
If you don't want an additional sourceButton, you can also do:
((Button)event.getSource()).getText().equals("clickMeButton"); though as the
size of your array increases you'll end up making a lot of unnecessary calls
to getSource( ) that way.
Another approach would be to simply implement the ClickHandler in a separate
class, say if you have a lot of buttons and a long if/else branching. You
could do:
public class MyClickHandler implements ClickHander {
Button sourceButton;
@Override
public void onClick(ClickEvent event) {
sourceButton = (Button)event.getSource();
if(sourceButton.getText().equals("clickMeButton")) {
Window.alert("works");
}
if(sourceButton.getText().equals("clickMe2")){
Window.alert("works2");
}
}
}
MyClickHandler myHandler = new MyClickHandler();
myButtons[i].addClickHandler(myHandler); // for both your buttons
To be honest, I haven't done much work with ClickHandlers yet, so there
might be a better approach to handle such scenarios. In particular, I would
check if assigning and using DOM ids for the widgets is an option. I am sure
it must be, I just haven't gotten around to that. :)
Either way, I hope this helps.
