Hi.
Thanks. I made static calls work, but I can't make it work on
instances.
Sorry for all the text below. The only question is on the last. Just
wanted to make sure that all details was here.
So imagine this webpage layout, split into different panels:
---------------------
| 1 | 2 |
| | |
| | |
| | |
---------------------
This is done as a GWT app, FooGUI(.java) in package dk.cfph.client.
In 1. I have a menu. When clicking on one of these items it loads some
html+javascript into panel 2 [put inside a Frame widget]. This html
+javascript is generated on the webserver that the GWT has contact
with.
I would like this javascript to be able to contact the GWT
application.
So what I have now is this:
In FooGUI I have these methods:
void tmpcall() {
Window.alert("Hello world!42foobar we got hole!!!! this='" + this +
"'");
}
static void tmpcallstatic() {
Window.alert("in tmpcallstatic!");
}
public native void tmpexpose() /*-{
$doc.exposedfunction = function() {
$wnd.alert('in tmpexpose()');
@dk.cfph.client.FooGUI::tmpcallstatic()();
[EMAIL PROTECTED]::tmpcall()();
$wnd.alert('end of tmpexpose()');
}
}-*/;
In the constructor I have this call: tmpexpose();
In the HTML which is put into the Frame on 2., I have this: ...<p
onclick="alert(\foo');exposedfunction()">click here</p>
When I click on it, I get these alerts:
'foo'
'in tmpexpose()' [meaning that we got contact to the native method]
'in tmpcallstatic!' [meaning that we got contact to the static java
method]
Then it stops. So this means that [EMAIL PROTECTED] did not work.
How can this be? I can sort of understand that "this." does not work.
But then again, I think it should :)
Any help?
/Tobias
