    <p>I have a QT application written in python using PySide and I stumbled across a little problem regarding the showFullScreen method of the QGLWidget (although the problem occurs with every other widget too):</p> <p>The problem is, that the widget doesn't have its 'final' resolution after the program returns from showFullScreen. The switch seems to be triggered asynchronously between 5 and 10 milliseconds later.</p> <p>This is a problem for me because I have to do some layout calculations which depend on the widget's size after it is shown.</p> <p>Below is a little reproducer which subclasses QGLWidget. Using this reproducer you will take notice, that resizeEvent will be called twice after showFullScreen.</p> <p>I'm looking for a convinient way of knowing which resizeEvent is the 'final' one, or a way of knowing, when the widget really is in fullscreen mode. Is there maybe any signals I could connect to?</p> <p>Thanks a lot for any help on this.</p> <pre class="lang-py prettyprint-override"><code>#!/usr/bin/python import sys from PySide.QtGui import QApplication from PySide.QtCore import QTimer from PySide.QtOpenGL import QGLWidget class TestWidget(QGLWidget): def __init__(self, parent=None): super(TestWidget, self).__init__(parent) self._timer = QTimer() self._timer.setInterval(5) self._timer.timeout.connect(self.showsize) self._timer.start() def resizeEvent(self, event): print "Resize event:", event.size().width(), event.size().height() def showsize(self): w = widget.size().width() print "Timer: ", w, widget.size().height() if w == 1680: self._timer.stop() if __name__ == "__main__": app = QApplication(sys.argv) widget = TestWidget() widget.showFullScreen() print "After showFullScreen:", widget.size().width(), widget.size().height() # this will always be 640 480...1680 1050 is what I'm expecting app.exec_() </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
