[PyQt] QSpinBox and setLineEdit

[Mpi]

Hi,

You can set a custom line edit on a spinbox using the method setLineEdit().
Suppose I implement a class that inherits from QLineEdit and overwirite the
'setText' method, you'd expect that pressing the arrow button on the spinbox
would trigger a call to your custom setText method. I can't get this to work
though. Code that reproduces the behavior is attched below,

Best regards,

import sys

from PyQt4 import QtCore, QtGui
        
class LineEdit(QtGui.QLineEdit):
    def __init__(self, parent=None):
        QtGui.QLineEdit.__init__(self, parent)

    def setText(self, text):
        print 'LineEdit', text
        QtGui.QLineEdit.setText(self, text)

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    widget = QtGui.QSpinBox()
    line_edit = LineEdit()
    widget.setLineEdit(line_edit)
 
    widget.show()
    sys.exit(app.exec_())
