Hmm, what is the actual text of the error message?
You can try taking out the comment from AddItem and make sure mDeskbarIconId is
an int32:
status_t err = mDeskbar.AddItem(mBtnCall, &mDeskbarIconId);
Also, try adding the "add-on" key to the archive as such with you application's
signature:
status_t
CustomPictureButton::Archive(BMessage *msg, bool deep) const {
status_t err;
err = BPictureButton::Archive(msg, deep);
msg->AddString("class", "CustomPictureButton");
msg->AddString("add-on", "your_app_signature");
return err;
}
