changing button icon on click

[la123]

Hi,

How can I change a button icon in onclick event?
button.setIcon() doesnt work (in smartGWT, build 1.0b1).

That's what I'm trying to do:

Button iconOnly= new Button();
iconOnly.setIcon("icon1.png"); 

Button otherButton = new Button();
otherButton.addClickHandler(new ClickHandler() {
            public void onClick(ClickEvent event) {
                iconOnly.setIcon("icon2.png"); //this line has no influence in UI
            }
        });

thanks!

You should see an IllegalStateException raised indicating that this property cannot be changed after the component has been rendered.

See the javadoc Button.setIcon

java.lang.IllegalStateException - this property cannot be changed after the component has been created

So changing of this property post-render is currently not supported. Perhaps the SmartClient folks can make this enhancement. Feel free to create an issue in tracker.

FYI Button.icon and IButton.icon will become a runtime-settable attribute as of 7.0 final.

This is now supported in SVN.
