I am noticing some strange text insertion behavior to a QPlainTextEdit widget when using a stylesheet. I'd like to use a 'fixed' font in my stylesheet. when i do this, i see that the text i want inserted 'inject' is actually missing the 'nj' characters so i end up with 'i ect' in the widget. when i use 'Courier' instead of 'fixed' font-family in the stylesheet, all is well. could it be due to my font server or problem with my environment? i don't have ready access to test on another machine outside of my environment.

here's the code:

Qt Code: 
  1. #include <QtCore>
  2. #include <QtGui>
  3.  
  4. //-----------------------------------------------------------
  5. //  main
  6. //-----------------------------------------------------------
  7. int main (int argc, char* argv[]) {
  8.  
  9.     QApplication app(argc, argv);
  10.  
  11.     QMainWindow *main_window = new QMainWindow();
  12.     main_window->setGeometry(100,100,800,600);
  13.  
  14.     //  if you use font-family: "Courier", output looks fine.  only problematic
  15.     //  with "fixed"
  16.     //
  17.     app.setStyleSheet(
  18.         "QPlainTextEdit{ font-family: \"fixed\"; }"
  19.     );
  20.  
  21.     QWidget *main = new QWidget();
  22.  
  23.     QPlainTextEdit *text = new QPlainTextEdit();
  24.  
  25.     QVBoxLayout *layout = new QVBoxLayout;
  26.     layout->addWidget(text);
  27.     main->setLayout(layout);
  28.  
  29.     main_window->setCentralWidget(main);
  30.  
  31.     //  this should show 'i ect' in the text window
  32.     //  NOTE:  'nj' chars are simply not printed
  33.     //
  34.     text->appendPlainText("inject");
  35.  
  36.     main_window->show();
  37.  
  38.     return app.exec();
  39.  
  40. }
