I've got a web page with an applet inside. This applet is a drop target on a drag and drop action from the OS, I simply take an image from a folder, drag it on the applet and something happens.
I give this webpage to a graphic designer and he ask to if he can put an image behind the java applet so he can simulate to change the background using CSS (it is a skinned app and graphic design can change during execution).
Practically i supposed to do:
<div>
<applet width="50" height="50" />
</div>
with this CSS:
div {
width:50px;
height:50px;
background-image: url(image.jpg) center center no-repeat;
}
But it doesn't work (background is opaque).
It is possible to set transparency to the applet without loosing drag and drop capabilities ?
I'm searching something similar to flash wmode parameter.
Better solutions implies only changes on the CSS/HTML without recompiling java class so the designing team can change the page structure without changing the Java.
You might pass the background image URL into the applet as a parameter, or have the applet use Javascript to interrogate the page to determine what background image is shown.
