[PyQt] returning a value from a sub-dialog

[Johoski, Timothy R]

I'm a newbie, so take this with a grain of salt...  The quick example below shows a dialog with a label and line edit, then after the user presses OK or Cancel (or hits return or escape), it prints what they typed in the line edit.  Hope this helps.

#/usr/bin/env python
import sys

from PyQt4.QtCore import *
from PyQt4.QtGui import *

app = QApplication(sys.argv)
dlg = QDialog()

l  = QLabel("Enter name:")
le = QLineEdit()
hl = QHBoxLayout()
hl.addWidget(l)
hl.addWidget(le)

bb = QDialogButtonBox(dlg)
bb.setStandardButtons(QDialogButtonBox.Cancel|QDialogButtonBox.Ok)
bb.accepted.connect(dlg.accept)
bb.rejected.connect(dlg.reject)

vl = QVBoxLayout(dlg)
vl.addLayout(hl)
vl.addWidget(bb)

retval = dlg.exec_()
name = le.text()

print "Dialog retval=%s, name entered=\"%s\"" % (retval, name)
