QTextEdit & Font Rendering

Observed in a QTextEdit built with Qt 4.3.1 and Qt 4.4.0. Rendering a character with a diacritic mark on top (such as À, Á, Â, Ã, Ä, Å, Ò, Ó, Ô, Õ, Ö, etc.), has only the main body of the character displayed, with sometimes all, and sometimes some of the diacritic mark visable.

Problem can be observed with the following code. Type a letter with a circumflex on top. Copy across about 10 characters, and resize the window so that the line breaks in to the second line of the QTextEdit and observe the difference in the letters in the first line compared with characters in the second line.

#include <QApplication>
#include <QHBoxLayout>
#include <QTextEdit>

class Test : public QWidget {
public:
Test()

{ QWidget *window = new QWidget; QTextEdit *mybox = new QTextEdit; mybox->setFont(QFont("DejaVu Sans Condensed Garmin", 72)); QHBoxLayout *layout = new QHBoxLayout; layout->addWidget(mybox); window->setLayout(layout); window->show(); }

};

int main(int argc, char* argv[])
{
QApplication app(argc, argv);
new Test;
return app.exec();
}
