He,
The following occurred against 1.6.4.
In hosted mode (IE 7 I quess as I have IE7 installed) I found out that
when I set the opacity in a FadeInAnimation.update(double) class that
is a subclass of Animation, it has no effect until I first set some
other style property...
Example:
In the FadeInAnimation.update method, I do something like (for IE in
hosted mode):
-----
update(double progress) {
getElement().getStyle().setProperty("filter", "alpha(opacity= " +
value * 100 + ")");
}
----
I tried the above in several ways, with the following simple test:
---
FlowPanel main = new FlowPanel();
RootPanel.get().add(main);
HTML html = new HTML("some text<br>more text<br>");
main.add(html);
FadeInAnimation an = new FadeInAnimation(html.getElement());
an.run(10000);
---
The html widget kept on showing up immediately, until I set another
style like the height in the above update statement before setting the
opactity, like:
----
update(double progress) {
this.element.getStyle().setProperty("height", "200px"); // NEW
this.element.getStyle().setProperty("filter", "alpha(opacity= " +
value * 100 + ")");
}
-----
And all of a sudden it worked... Appearantly the opacity statement
doesn't trigger a css refresh.
Anybody an idea what's happening here? Doe anybody else experience
this as well, or can try this ?
BTW: I used a clean html page without any style definitions to make
sure that not some strange style was causing this.
