    You would need to load the image outside and then you can get a load event. Once it's loaded then you can set the background image to the image.

    Default How exactly?

    How exactly?


    Could you clarify a little bit? Would you load using Ext.Img first, then assign as a background image after?

    I am trying to do the same thing...

    No , in fact I would like to load a picture as background of a container. The picture is big and takes some time so I would like to mask de viewport while the picture is loading and unmask it when de image is loaded.

    Regards

    Cédric.

    Hi yes I am trying to do the same thing....I meant can Mitchell clarify a little bit.

    When he says 'You would need to load the image outside and then you can get a load event. Once it's loaded then you can set the background image to the image.'

    What does he mean by 'load the image outside' does he mean load it perhaps at init before anything else has loaded? I am not sure how to do this.

    :-)

    use Ext.img's load event which is fired when image is actually finished loading (check the docs)
    use a listener to catch this event and only then add the image to the viewport.

    Sencha guys, I think such a behavior (loading an image in the background and displaying a loading animation until it is loaded) is so common it could have been a part of the framework without waiting for extensions.

    also, you can take a look at mitchel's image loader https://github.com/mitchellsimoens/Ux.ImageLoader for ideas.its from 8 months ago so not written for 2.1 but worth the look.
