Hi, I'm trying to write a program that creates an onscreen keyboard that uses an 2-analogue stick joypad for input. I'm having issues becuase the joystick needs to be polled regularly. I'm using a QTimer to call a paintEvent update() that polls the joystick in the main class (Keyboard). However there's some other drawing i want to do when the joystick is polled. However the drawing is supposed to be done by a different class with its own graphics etc (called Ring), and i found the only way that seemed to work was to put the drawing i want to do in the paintEvent of that class and both seem to get called. But this seems kinda weird, and for some reason if i simply called the drawing to be done by Ring as a method of the Ring object in the paintEvent of Keyboard it doesn't work. I'm sorry if there's a bit confusing, i'm very new to programming and QT and also asking questions on mailing lists.
Basically doing Class keyboard() ... self.timer.start(50) self.connect(self.timer, QtCore.SIGNAL('timeout()'), self, QtCore.SLOT ('update()')) ... def paintEvent() ...poll the joystick Class Ring() ... def paintEvent() ... do the ring drawing works, but doing Class keyboard() ... self.timer.start(50) self.connect(self.timer, QtCore.SIGNAL('timeout()'), self, QtCore.SLOT ('update()')) ... def paintEvent() ...poll the joystick ...ring.drawstuff() Class Ring() ... def drawstuff() ... do the ring drawing Just lands me with a blank window. Hope someone can help explain this. thanks
