Wt

I'm trying to make an application work properly with internal paths. I think I understand the basics, and I have working WAnchors that fire internalPathChanged, which is handled by a working slot. But I'm stuck on how load the correct state the path the initially launches the application. I feel like I must be missing something obvious here.

My first problem is that before the first call to setInternalPath(), internalPath() always returns the empty string, regardless of whether I launched the app from http://example.com/rootofapp or http://example.com/rootofapp/a/b/c/d. How can I tell what my initial path should be?

My second problem is that setInternalPath(p, true) doesn't fire a change event if the internal path is already p. I can see the logic in this, but in the case of initializing the application, if I call setInternalPath("/") from the constructor of my app, no event is fired if the launch URL is http://example.com/rootofapp. Similarly, if I call setInternalPath("/a/b/c/d") from the constructor, no event is fired if the launch url was http://example.com/rootofapp/a/b/c/d. This suggests that Wt knows what the initial internalPath() is, despite the fact that it tell me it is the empty string.

I see that the Wt homepage supports supports deep linking like this, and I looked at the source, but I couldn't find any magic. Is there supposed to be an internalPathChanged() signal firing at start up time that I'm not getting for some reason?

Any help? I'm using 3.3.0.
