Question

I have 2 QTextEdit widgets and I need to put whatever is entered in the first to the second on a press of the enter key (Return)…. I am not able to implement it please help?

I know I need to use KeyPressEvent but I don’t understand how to use it only for the QTextEdit??

self.textEdit = QtGui.QTextEdit(self.widget)
self.textEdit.setMinimumSize(QtCore.QSize(201, 291))
self.textEdit.setMaximumSize(QtCore.QSize(201, 291))
self.textEdit.setObjectName("textEdit")
self.textEdit.setReadOnly(True)
self.verticalLayout.addWidget(self.textEdit)

self.textEdit_2 = QtGui.QTextEdit(self.widget)
self.textEdit_2.setMinimumSize(QtCore.QSize(201, 41))
self.textEdit_2.setMaximumSize(QtCore.QSize(201, 41))
self.textEdit_2.setObjectName("textEdit_2")
self.textEdit_2.setFocusPolicy(Qt.StrongFocus)
self.verticalLayout.addWidget(self.textEdit_2)

Any help is appreciated I am stuck…..

Here is a small example that shows QLineEdit and its returnPressed signal. Upon pressing return the text in the QLineEdit will be appended to the QTextEdit:

import sys
from PySide import QtGui

class Window(QtGui.QWidget):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        self.output = QtGui.QTextEdit()
        self.output.setReadOnly(True)

        self.input = QtGui.QLineEdit()
        self.input.returnPressed.connect(self.addInput)
        self.input.setPlaceholderText('input here')

        layout = QtGui.QVBoxLayout(self)
        layout.addWidget(self.output)
        layout.addWidget(self.input)

    def addInput(self):
        # skip empty text
        if self.input.text():
            self.output.append(self.input.text())
        # clear the QLineEdit for new input
        self.input.clear()

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)

    w = Window()
    w.show()

    sys.exit(app.exec_())
