You could connect the button to a slot in the second window that sends
the text back to the first window.
Here's an example that sends the text to a function. You could substitute a
class for the function to get what you want.
import sys
from qt import *
class Window(QWidget):
def __init__(self, parent = None):
QWidget.__init__(self, parent)
self.textEdit = QTextEdit(self)
okButton = QPushButton(self.tr("&OK"), self)
self.connect(okButton, SIGNAL("clicked()"), self.sendText)
layout = QVBoxLayout(self)
layout.addWidget(self.textEdit)
layout.addWidget(okButton)
def sendText(self):
self.emit(PYSIGNAL("textEntered(QString)"), (self.textEdit.text(),))
def fn(text):
print text
if __name__ == "__main__":
app = QApplication(sys.argv)
window = Window()
window.connect(window, PYSIGNAL("textEntered(QString)"), fn)
window.show()
app.setMainWidget(window)
sys.exit(app.exec_loop())
Note the use of PYSIGNAL() instead of SIGNAL(). With PyQt4 you would be able
to use SIGNAL() and write the emit() call in a simpler form.
