[Paraview] Custom Panel Force Accept

[Brian C. Panneton (CONTR)]

I have a custom panel which has a QListWidget. The panel updates the

widget when another panel widget gets changed. I have a SLOT which 
catches this change, modifies the QListWidget. I have another SLOT catch 
when the QListWidgetItems are checked/unchecked and calls 
this->setModified(). Thus the accept button is highlighted. However, 
when you click accept, RequestData does not get called. Is there a way 
to catch the accept signal and force a RequestData?

Thanks,
Brian Panneton
