    Description

      latest 5.3 branch, -opengl desktop, vc2010

      in qlineedit-qtextedit-chinese-inputmethod.PNG file, top 2 are QLineEdit, bottom 2 are QTextEdit. For example,

      1. switch to Chinese input method
      2. mouse click in QLineEdit 1 and input "wo"
      3. then do not confirm that, and mouse click in QLineEdit 2, input "wo" again

      You will see two "wo" in QLineEdit 2, that's same behavior when I test in the Tools-Options in Visual Studio 2010, like c2010-tools-options-chinese-inputmethod.PNG. But the QLineEdit 1 still has "wo", and you can not use backspace to delete them in English keyboard, that's different than the native behavior.
