ENH: Fixed issues related to Qt5
- There seems ot be a bug w/r to QT5's signal and slots concerning when passing a reference to const JSON data - pqPresetDialog's apply preset signal should pass JSON data when a preset is selected. If the signal is connected to a slot that takes in no argumenets the signal is properly connected. However, if you connect the signal to a slot that taked in the reference to the JSON object, the connect method says there is no such slot.
Workaround - instead of using the SLOT and SIGNAL macros, directly pass in the methods.
- In Qt5 , Frames no longer have a setShown method but instead now use setVisible.
