Hi Michael,
here's how to add a hover effect to an image:
Extend qx.ui.basic.Image, assign a custom appearance id and add
listeners that add/remove the "hovered" state on mouseover/mouseout:
qx.Class.define("custom.HoverImage", {
extend : qx.ui.basic.Image,
construct : function(source) {
this.base(arguments, source);
this.setAppearance("hoverimage");
this.addListener("mouseover", function() {
this.addState("hovered");
});
this.addListener("mouseout", function() {
this.removeState("hovered");
});
}
});
Add a new appearance definition to
source/class/<application>/theme/Appearance.js:
qx.Theme.define("custom.theme.Appearance",
{
extend : qx.theme.modern.Appearance,
appearances :
{
"hoverimage" :
{
style : function(states)
{
return {
decorator : states.hovered ? "tooltip-error" : undefined
};
}
}
}
});
As you can see, the "tooltip-error" decorator is assigned/removed
according to the "hovered" state. I'll leave it up to you to define your
own decorator.
Regards,
Daniel
