Sorry to jump into this tangent of the Qt conversation. I have very
little experience with Qt, but a simple probe-like application (see
below) to connect Qt with Epics through python is remarkably simple.
I'd be happy to add "epics-aware" Qt widgets to pyepics, but don't
know enough Qt to do this myself.

This is using pyside, tested on Windows only.
#!/usr/bin/env python
import epics
import sys
from PySide.QtGui import QWidget, QLabel, QLineEdit, QGridLayout, QApplication
class PVProbe(QWidget):
def __init__(self, parent=None):
QWidget.__init__(self, parent)
name_label = QLabel("PV Name:")
self.pvname = QLineEdit()
value_label = QLabel("PV Value:")
self.value = QLabel(" ")
self.pvname.returnPressed.connect(self.onPVNameReturn)
self.pv = None
grid = QGridLayout()
grid.addWidget(name_label, 0, 0)
grid.addWidget(self.pvname, 0, 1)
grid.addWidget(value_label, 1, 0)
grid.addWidget(self.value, 1, 1)
self.setLayout(grid)
self.setWindowTitle("PySide PV Probe:")
def onPVNameReturn(self):
self.pv = epics.PV(self.pvname.text(), callback=self.onPVChange)
def onPVChange(self, pvname=None, char_value=None, **kws):
self.value.setText(char_value)
if __name__ == '__main__':
app = QApplication(sys.argv)
probe = PVProbe()
probe.show()
sys.exit(app.exec_())
