Also search for "Product Name" in your Xcode project settings and change it to something unique. I've had the same problem some years ago where SurfaceSPREAD would collide with other plugins even though it had a unique ID. Changing the product name helped for some weird reason that only Xcode fans understand ^^

Thanks to both of you, I've got them working now. I would never have looked inside the xcodeproj to try to fix it. Thanks a ton.

Also, I saw a couple threads about SetCallBackURL but none of them had answers, does any one know how it interacts with a HTML custom gui? Can you get feedback back from it with SetCallBackURL?

Hi Dan,

The URL callback is called whenever a new URL has been selected, either if the user clicked on a link or if the plugin programmer calls HtmlViewerCustomGui::SetUrl(). In the callback you then have access to the string URL of the new page and information on the string encoding.

Thanks, Yannick.

What I'm mainly confused about is the syntax for calling the function. Would I do:

      
//virtual Bool CreateLayout(void)  
    
       viewer = AddCustomGui(DIALOGID, CUSTOMGUI_HTMLVIEWER, "pyBROWSER", BFH_SCALEFIT|BFV_SCALEFIT, 512, 250, bc);  
        
        
      HtmlViewerCustomGuiURLCallback callback;  
      HtmlViewerCustomGui* view;  
      view = (HtmlViewerCustomGui* )viewer;  
      view->SetURLCallback(callback, <#void *user_data#>)  
        
      view->SetUrl("https://www.google.com/", URL_ENCODING_UTF16);

If that's right, what would userdata be in this circumstance?
And how would I set up the call to that callback?

A callback is a function, so here's how you can define it for the HtmlViewerCustomGui:

void htmlViewerCallback(void* user_data, const String& url, LONG encoding, void* reserved)
{
    GePrint(url);
}
  
virtual Bool CreateLayout(void)
{
    ...
    htmlViewer->SetURLCallback(htmlViewerCallback, NULL);
    ...
}

The user data is used to have a custom object accessible in the callback so you can set it to NULL if you don't need it. The user data could be set to htmlViewer if you want to access the HtmlViewerCustomGui from the callback for example.

Thank again Yannick.

Should I be able to just cop and paste that? I've been trying to get it working but I've been getting an error saying that there's "no function call to SetURLCallback(<unresolved overloaded function>,Null)".

I've been reading though your last post here, but I haven't had any luck with that either.
Thanks for all the help.

Callback methods can be very confusing unless you see a full working example of them in action.
So maybe this example will help.

This is the entire .cpp code for a very basic dialog plugin example with no external resources.
When the plugin opens. The HtmlViewerCustomGui fetches the Google website and displays it in the plugin.
When the button is clicked. It loads the Maxon website. Plus... it also calls to the htmlViewerCallback() method and runs the code inside of it.
In this case it just prints url.

Example:

// Testing ID# Only!!!!   Be sure to use a unique ID obtained from www.plugincafe.com  
#define PLUGIN_ID 1000006  
  
#include "c4d.h"  
#include "gui.h"

#include "customgui_htmlviewer.h"

Thanks so much Scott, it works perfectly.

Is there a way to get any other type of information from a website besides a url? For example could I get an array from a website or something similar?

Thanks a bunch!

Look up GetTextArea in the docs.
That function might possibly read the text in the loaded HTML page.
I never use this URL stuff. So I don't really know what all of the possibilities are.

I've have had difficulty with understanding how to use the callbacks in the SDK myself. And Yannick helped me understand how to use them in a previous thread.
That's really all I can offer advice about.
