Re: [qooxdoo-devel] Changing source of Image widget

[Claus Straube]

Hi Stefan,

have you tried to save an other image as dummy? Like this:

--snip--
// Create a button
var button1 = new qx.ui.form.Button("Change Image");
var image = new
qx.ui.basic.Image("http://www.catify.com/demo/images/ftp.png";);


// Document is the application root
var doc = this.getRoot();

// Add button to document at fixed coordinates
doc.add(button1,
{
  left : 100,
  top  : 50
});

doc.add(image,
        {
          left : 200,
          top : 50
        });

// Add an event listener
button1.addListener("execute", function(e) {
  
  if(image.getSource()==null){
    image.resetSource();
    image.setSource("http://www.catify.com/demo/images/ftp.png";);
    this.debug("image source was null and is --> " + image.getSource());
  } else {
    image.resetSource();
    image.setSource("http://www.catify.com/demo/images/dummy.png";);
    this.debug("image source was not null and is --> " +
image.getSource());
    image.resetSource();
  }
}, this);
--snip--

Best regards - Claus
