Hi thron7
sorry, "this.getIFrame()" is a local property getter of the form. It
returns the iframe :)
And yes, setSource() was used before, my example is executed inside an
"execute" event of a button when the page was loaden inside the iframe
by myself.
getIframeNode() was an example that the iframe html object itself exists.
alert(qx.html.Iframe.getWindow(this.getIFrame()));
-> showns "null", too
But:
alert(this.getIFrame().getContentDocument());
-> shows "[object HTMLDocument]"
So only the window doesn't work
thron7, did Fabians example works for you?
Did anyone has a example skelleton to post here where I can see it
working? I also think that the problem is in my code, the code of
qooxdoo looks good, but I don't find the problem. A complete executable
example could help. Thx if anyone takes the time to write this :)
Greetings,
Leander
