Image manipulation in Qt console app segfaults?

MWPau

Hi all,

Can someone tell me why the following creates a segfault?
It does so at the drawText line.

@
int main(int argc, char *argv[])
{
QApplication app(argc, argv, QApplication::Tty);

QImage img(800, 800, QImage::Format_RGB16);
QPainter painter(&img);

QFont font("utsaah", 50, QFont::Bold, true);
painter.setPen(QPen(Qt::white));
painter.setFont(font);

painter.drawText(0,0, 200,200, Qt::AlignLeft, "blah");

return 0;

}
@

Is there any way i can make this work without it needing to become a Qt GUI app?

Thanks in advance.

Hi,

what do you mean by "... become a Qt GUI app" or a "... Qt console app"? When you create Qt Console project with the QtCreator your pro-file has a

@QT -= gui@

in which case the code given does not compile, because QApplication, QPainter and QImage are not available.

So, do you want to avoid creating a QWidget of any kind? That should be no problem. In fact, when commenting the above line

@#QT -= gui@

I can compile your code and execute it without any problems.

I should mention this is qt-embedded.

It segfaults if i use:
@
QApplication app(argc, argv, QApplication::Tty);
@

But if i use this it works fine (but i dont want the extra weight of the QWS/GUI).
@
QApplication app(argc, argv);

Then I'm out, sorry. Not worked with Qt-embedded yet.
