Greetings,
Newbie hits wall while dipping toe in QCanvas.
Would someone be kind enough to tell
me why I get a segfault while trying to "show()" a sprite?
my entire code:
# START OF CODE --------------------------------------------
#
# Testing QCanvas
#
import sys
from qt import *
from qtcanvas import *
TRUE = 1
FALSE = 0
class MY(QCanvas):
def __init__(self,h = 1000, w=1000):
QCanvas.__init__(self,h,w)
self.view = QCanvasView(self)
# testing text
self.item = QCanvasText('Testosterone',QFont (),self)
self.item.setX(50)
self.item.setY(50)
self.item.show()
# testing sprite
spix = QCanvasPixmapArray()
spix.setImage(0,QCanvasPixmap("test.png"))
sprite = QCanvasSprite(spix, self)
sprite.move(100, 100, 0)
sprite.show() #<-- gives Segmentation fault
# error message:
#QPixmap::operator=: Cannot assign to pixmap during painting
# Note: if commenting out the "sprite.show()" line, the QCanvasText
# shows up as expected.
# show items on screen
self.view.show()
self.update()
if __name__ == "__main__":
a = QApplication(sys.argv)
QObject.connect(a,SIGNAL("lastWindowClosed()"),a,SLOT("quit()"))
w = MY()
a.exec_loop()
# END OF CODE --------------------------------------------
Kind Regards,
Vio
