reimplement QPlainText’s focusInEvent in another source file ,how to ?

[Philip]

The UI is as following

 

The UI is as following

http://img.my.csdn.net/uploads/201211/07/1352267120_2257.jpg

I saved  the  form as a file named re.ui

Then I convert it into Python script named ui_re.py

Third ,I create the source file with the name

callFirstApp.pyw and import the ui_re.py to it

The code in the callFirstApp.pyw is as shown here:

@

import sys

from PySide.QtGui import *

from ui_re  import *

class MainWindow(QMainWindow, Ui_MainWindow):

    def __init__(self, parent=None):

        super(MainWindow, self).__init__(parent)

        self.setupUi(self)

        self.plainTextEdit.setPlainText("Type code here...")

        

  

if __name__ == '__main__':

    app =QApplication(sys.argv)

    frame = MainWindow()

    frame.show()    

    app.exec_()

@

I want to reimplement the QPlainText’s focusInEvent in this file ,my code is as following 

(means let the default text "Type code here..." disappear when focus  in the QTextEdit’s editable area)

@

def focusInEvent(self, event):

        self.clear()

        QPlainTextEdit.focusInEvent(self, event)

@

But I don’t know how to add the code to the file correctly ?

Thanks in advance .

I don't use designer at all.

In this situation, i will write a class to represent the UI(which inherits from QPlanTextEdit).

Then define a focusInEvent method for it.

That'd be much easier.

When you designe the ui, you don't need to place the QPlainTextEdit in the main window.

You should inherited A QPlainTextEdit and reimplemented the focusInEvent method.

Then in the MainWindow's __init__, you can insert the PlainTextEdit into the ui window.

好吧，英文很烂，不知能不能看懂。

I believe what Jimmy told was also to suggest you write the QPlainTextEdit stuff inside your "callFirstApp.pyw" file.

丸子写的我懂了。我英语也很烂。

Allow me, no offense, 一个小地方： 

You should inherited --> You should inherit    # (should 后接原形）

还有后面的reimplemented也改成一般时态就可以了。

Hope it helps :)
