Now I have changed my application code to something like this based on your
inputs:
Main application:
qx.Class.define("my.application.Main",
{
extend : qx.application.Gui,
statics :
{
frameTop: new qx.ui.embed.Iframe("top.html"),
frameMain: new qx.ui.embed.Iframe("default.html"),
frameBottom: new qx.ui.embed.Iframe("status.html"),
setMainFrameSource: function(frameSource)
{
var d = qx.ui.core.ClientDocument.getInstance();
d.dispatchEvent( new qx.event.type.DataEvent("surfTo", frameSource
) );
}
},
members :
{
main : function()
{
// Call super class
this.base(arguments);
var d = qx.ui.core.ClientDocument.getInstance();
//Set properties for IFrames
my.application.Main.frameTop.setTop(0);
my.application.Main.frameTop.setLeft(0);
my.application.Main.frameTop.setWidth("100%");
my.application.Main.frameTop.setHeight(100);
my.application.Main.frameTop.setBorder(null);
d.add(my.application.Main.frameTop);
my.application.Main.frameMain.setLeft(0);
my.application.Main.frameMain.setTop(100);
my.application.Main.frameMain.setWidth("100%");
my.application.Main.frameMain.setBottom(30);
my.application.Main.frameMain.setBorder(null);
d.add(my.application.Main.frameMain);
my.application.Main.frameBottom.setLeft(0);
my.application.Main.frameBottom.setWidth("100%");
my.application.Main.frameBottom.setBottom(30);
my.application.Main.frameBottom.setBorder(null);
d.add(my.application.Main.frameBottom);
// make qx.ui.embed.Iframe react to event "surfTo" via function
changeURL()
d.addEventListener("surfTo", this.setMainFrame,
my.application.Main.frameMain);
},
setMainFrame: function(e) {
alert("Setting...");
my.application.Main.frameMain.setSource(e.getData());
}
}
});
Application 1 : set to frameTop IFrame:
qx.Class.define("my.application.TopNavigation",
{
extend : qx.application.Gui,
members :
{
__mainNavToolbar: null,
main : function()
{
// Call super class
this.base(arguments);
__mainNavToolbar = new qx.ui.toolbar.ToolBar;
__mainNavToolbar.setLeft(200);
__mainNavToolbar.setRight(100)
__mainNavToolbar.setTop(50);
var tbp = new qx.ui.toolbar.Part;
var btnHome = new qx.ui.toolbar.Button("Home",
"resource/qx/icon/VistaInspirate/22/actions/go-home.png");
btnHome.addEventListener("execute", function(e) {
my.application.Main.setMainFrameSource("test.html");
}
);
tbp.add(btnHome);
__mainNavToolbar.add(tbp);
__mainNavToolbar.addToDocument();
}
}
});
Now, the error has disappeared. I am able to access the IFrame from the
my.application.Main class. But, when I dispatch the surfTo event from the
static method the function registered to handle it is not getting called. No
error in Firebug or FF error console.
I think this is not a trivial issue.
Thanks,
Phaneesh

application
Phaneesh,
you need to make accessible the Iframe widgets you create, e.g. through
a variable of your "master" Application class, so one Iframe widget can
get hold of the other during runtime.
Let's suppose you saved all your Iframes in an array "allMyIframes" of
your master Application class, then you can access one of them from an
Iframe app like this:
if (parent && parent.qx != window.qx) {
var mySecondIframe =
parent.qx.core.Init.getInstance().getApplication().allMyIframes[1];
...
Now you should be able to invoke your desired method:
mySecondIframe.setMainFrame("default.html");
The saving of the Iframe widgets to the parent app works the same way
(e.g. through
"parent.qx.core.Init.getInstance().getApplication.addIframe(this.frameMain);"
which would add to the allMyIframes array).
(Alternatively to using the parent app as a keeper for your Iframe
widgets you could use a static array of your com.myapplication.Main
class, but only if all three embedded iframes are implemented using this
class.)
The problem with your approach is that you are calling an instance
method as if it were a class (static) method, hence the error message.
