Description Bruno Bigras 2011-07-04 20:26:38 EEST

Since bug 882 is fixed we can pass a PySide.QtGui.QApplication.Type to 
QApplication's constructor to use a QApplication without X but I got a segfault
trying to do :

import sys
from PySide.QtGui import QApplication
from PySide.QtGui import QGraphicsScene

app = QApplication(sys.argv, QApplication.Tty)
scene = QGraphicsScene()
scene.addText("test")

-
Thanks!

You get the same segfault with the C++ version of this program:

#include <QApplication>
#include <QGraphicsScene>

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

    QGraphicsScene scene;
    scene.addText("test");
}

Before crashing Qt throw the following qFatal message:

ASSERT: "!"No style available in non-gui applications!"" in file
/home/hugo/src/qt/src/gui/kernel/qapplication.cpp, line 1425

So if it's really a bug, it's a Qt bug not a PySide bug, anyway thanks for
reporting it!

Regards.
