qtserverprocess Module

Pyqt example to demonstrate how openrave elements can be controlled by a qt-gui.


Running the Example: --example qtserverprocess


This example shows how a qt-gui can control openrave functionality. If an environment with a robot is loaded, a random pose is generated for which a trajectory is planned. This trajectory can be replayed using the qt-gui.
