Re: [PyQt] List Widgets, adjustable
Do you mean something like a QSplitter? A splitter lets the user control the size of child widgets by dragging the boundary between the children. Any number of widgets may be controlled by a single splitter. Reference: http://doc.trolltech.com/4.5/qsplitter.html Matt Smith schrieb: Okay, I've got two QListWidgets in a frame with an HBoxLayout. I was looking for some suggestions to make the width of the two widgets adjust-able. Ideally I would like to be able to grab the space between the widgets with the mouse and move it to adjust the way that the available space is distrubuted, ie one gets larger and the other gets smaller. thanks mbs ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Re: [PyQt] segfault when using a proxy and SIGNAL( "clicked(QModelIndex)" )
Why do you need access to the QModelIndex internal pointer? It sounds like you are trying to access a null pointer, causing a crash. Looking at the signature, ptr is some sort of id or extra data associated with the index, which you probably need to add yourself when creating an index.

[PyQt] Annoying TypeError with graphics animations
Hello all, I get some strange TypeErrors when I use the QGraphicsItemAnimation. An example can be boiled down to the example below taken from the Qt documentation : http://doc.trolltech.com/4.5/qgraphicsitemanimation.html What I get is this error, when the application is running. "TypeError: native Qt signal is not callable" I have installed the snapshot : PyQt-x11-gpl-4.5-snapshot-20090403.tar.gz under python2.6 ( verified the error under python2.5 too ) I can hardly see that I do something wrong.. or is it my installation that has failed?? best Regards BBZ # --- 8< -- import sys from PyQt4.QtGui import QApplication , QGraphicsEllipseItem , QGraphicsItemAnimation from PyQt4.QtGui import QGraphicsScene , QGraphicsView from PyQt4.QtCore import SIGNAL , QPointF , QTimeLine app = QApplication( sys.argv ) # create a graphicsview with a moving ball... ball = QGraphicsEllipseItem(0, 0, 20, 20) timer = QTimeLine(5000) timer.setFrameRange(0, 100) animation = QGraphicsItemAnimation() animation.setItem(ball) animation.setTimeLine(timer) for i in xrange( 200 ) : animation.setPosAt(i / 200.0, QPointF(i, i)) scene = QGraphicsScene() scene.setSceneRect(0, 0, 250, 250) scene.addItem(ball) view = QGraphicsView(scene) view.show() timer.start() app.exec_() # --- 8< -- ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

Sounds like a problem with the C++ libraries.

Should be fixed in tonight's snapshot.

From what I've read so far, that sounds like bad news. :( Well, only in so much as you should spawn of processes to do this work... Encoding sounds like something that should be pretty easily wrapped up in separate spawnable processes.
