Re. the advice to edit container.js.
Editing container.js seems to effect the getUrlTemplate method in the code
which is inserted into the gadget. Ie. the value that I put in container.js is
I think the value that will be returned by getUrlTemplate. I can't see though
how this is used when you switch to canvas mode? What is the urlTemplate used
for?
In the container code there is a method requestNavigateTo. This calls
getUrlForView to obtain a url. 'canvas' appears to be hardcoded in
shindig-container.js like this:
shindig.IfrGadgetService.prototype.getUrlForView = function(
view) {
if (view === 'canvas') {
return '/canvas';
} else if (view === 'profile') {
return '/profile';
} else {
return null;
}
};
This code does not be appear to be effected by the container.js file which I
think is only used to populate the gadget code not the container.
So I still have the effect that when the gadget calls
requestNavigateTo('canvas') the requestNavigateTo method in the container does
a document.location.href = 'canvas'.
Our solution for now is to hack (could override obviously) this method in
shindig-container: shindig.IfrGadgetService.prototype.requestNavigateTo
so that where it does document.location.href = 'canvas'. it now does:
document.getElementById('test').innerHTML = 'draw gadgetx'+id+url;
Eventually this would become a few lines of code to render the gadget in an
overlay or a div which took up the full width of the page.
So - I have two questions:
What is the getUrlTemplate method in the gadget code all about?
Is my approach to getting a gadget to render in an overlay, or 'large' div
outlined above sensible?
Ultimately my aim is to get an effect similar to going to canvas mode in
iGoogle.
Thanks
