I'll include this in the next release

Thank you for your response.

I tested a modified version (converted to Java) to be able to override onCancel() using an anonymous class (example in first post).
However it does not work because DialogFragment#show(FragmentManager manager, String tag) fails with:

java.lang.IllegalStateException: Fragment null must be a public static class to be properly recreated from instance state.

It doesn't like an anonymous PleaseWaitDialog instance.

A solution to this issue would be to add this function to set a cancel listener (and not declare the class open as it cannot not work):

 public void setOnCancelListener(DialogInterface.OnCancelListener listener) {
      onCancelListener = listener;
   }

And add this override to onCancel() in PleaseWaitDialog :

 @Override
   public void onCancel(@NonNull DialogInterface dialog) {
      super.onCancel(dialog);
      if(onCancelListener != null) {
         onCancelListener.onCancel(dialog);
      }
   }

Same thing could be done for the dismiss listener.

Thanks for your suggestion. I'll definitely test it out because I don't have an idea either.

I looked this up and found that it's not recommended to use inner classes for Fragments as it may cause a memory leak. I'll add some listeners later but for now I've made PleaseWaitDialog class open so you can subclass it for your purpose.
