so i'm finally in the process of upgrading from 1.5.3 to 2.0, and
converting all my listeners to handlers. i have a listener class that
is always used in conjunction with an image - when the image is
clicked on the listener adds a style name indicating it's been
clicked.
current code, in the class implementing ClickListener:
public void onClick( Widget sender )
{
sender.addStyleName( "clickedIcon" );
if ( sender instanceof FocusWidget )
((FocusWidget) sender).setFocus( false );
}
attempted replacement code, in class now implementing ClickHandler:
public void onClick( ClickEvent event )
{
event.getRelativeElement().setAttribute(.... maybe? ...);
event.getRelativeElement().blur();
}
presumably i can always blur an Element, and as such don't need the
check for a FocusWidget equivalent. however, how can i add a style
name? am i going to have to modify the constructor of the class and
pass a reference to the Image Widget?
any help on this would be much appreciated. thanks in advance!
