Ok,
I used just basic approach, if anyone is interested in enabling/
disabling click events on your
own composite here it is:
public class MyButton extends Composite implements HasClickHandlers,
ClickHandler {
private final HashSet<ClickHandler> clickHandlers;
private boolean enabled;
public MyButton() {
clickHandlers = new HashSet();
addDomHandler(this, ClickEvent.getType());
.......
initWidget(<your_complex_widget>);
}
public HandlerRegistration addClickHandler(ClickHandler handler) {
clickHandlers.add(handler);
// don't care about the return value, nobody should need it
// if necessary return some convenient class extending
HandlerRegistration
// or create some special method for removing the click
handler from the clickHandlers list
return null;
}
public void onClick(ClickEvent event) {
if (enabled) {
for (ClickHandler handler : clickHandlers) {
handler.onClick(event);
}
}
}
public void setEnabled(boolean enabled) {
this.enabled = enabled;
}
}
Any suggestions for improvements are welcome.
