| Issue |
I need to call a Photon application (acting as a modal application) from another running Photon application. We read all the documentation but we couldn't detect the benefits of using PtSpawn versus Spawn. Any suggestions?

| Solution |
The biggest benefit is that it is portable to Neutrino. Also, PtSpawn() gives you more flexibility with notification of the parent, attaching a callback on termination, etc. The third major benefit is that it uses a background handler which will allow damaged widgets to automatically be updated. |
