Say I have an S开发者_运维技巧VG element, as follows. How do I add an onClickListener?
solved, see below.
I'm going to guess you're meaning a FieldChangeListener
rather than an OnClickListener
(wrong platform ;). SVGImage
isn't part of the RIM-developed objects, so unfortunately you won't be able to. Anything that is going to be able to have a FieldChangeListner
has to be a subclass of the net.rim.device.api.ui.Field
class.
Just in case someone's interested in how it's done...
try {
InputStream inputStream = getClass().getResourceAsStream("/svg/sphere1.svg");
_image = (SVGImage)SVGImage.createImage(inputStream, null);
_animator = SVGAnimator.createAnimator(_image, "net.rim.device.api.ui.Field");
_document = _image.getDocument();
_svg123 = (SVGElement)_document.getElementById("123");
}
catch (IOException e) { e.printStackTrace(); }
Field _svgField = (Field)_animator.getTargetComponent();
_svgField.setBackground(blackBackground);
add(_svgField);
_svg123.addEventListener("click", this, false);
_svg123.addEventListener("DOMFocusIn", this, false);
_svg123.addEventListener("DOMFocusOut", this, false);
}
public void handleEvent(Event evt) {
if( _svg123 == evt.getCurrentTarget() && evt.getType() == "click" ){ Dialog.alert("You clicked 123"); }
if( _svg123 == evt.getCurrentTarget() && evt.getType() == "DOMFocusIn" ) { ((SVGElement) _document.getElementById("outStroke123")).setTrait("fill", "#FF0000"); }
if( _svg123 == evt.getCurrentTarget() && evt.getType() == "DOMFocusOut" ) { ((SVGElement) _document.getElementById("outStroke123")).setTrait("fill", "#2F4F75"); }
}
