我用qtdesigner和python编写了一个小GUI,它应该实时显示matplotlib图中一个粒子的轨迹。所以我有类似的东西:
class DesignerMainWindow(QtGui.QMainWindow, Ui_MplMainWindow):
"""Customization for Qt Designer created window"""
def __init__(self, parent = None):
# initialization of the superclass
super(DesignerMainWindow, self).__init__(parent)
# setup the GUI --> function generated by pyuic4
self.setupUi(self)
self.niter = 30
#... other initializations
def run(self):
# set xo, yo with initial particle position
for t in range(self.niter):
# set new particle position in x, y
self.mpl.canvas.ax.plot([xo, x], [yo, y], '-b')
self.mpl.canvas.draw()
print x, y, t, self.niter
xo = x
yo = y
我的问题是,只有在函数" run()"尽管打电话给" draw()"在循环内。因此,我只有最终的轨迹,而不是完整的电影......
有没有人知道如何在此函数/循环中强制执行图形更新?
感谢。
