我有两个文件,分别是game.py 和map.py。以下简化代码位于其中:
from PyQt4.QtGui import *
from PyQt4.QtCore import *
from datetime import *
from map import *
class Game:
Scene = QGraphicsScene
View = QGraphicsView
@staticmethod
def start():
Game.App = QApplication(sys.argv)
Game.Scene=QGraphicsScene();
Game.Scene.setBackgroundBrush(QBrush(QColor(Qt.green)));
Game.View=QGraphicsView(Game.Scene);
print Game
map=Map()
Game.App.exec_()
if __name__=='__main__':
Game.start()
和文件map.py:
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from game import *
class Map(QObject):
def __init__(self,parent=None):
super(Map,self).__init__(parent);
print Game
v=Game.View
print v
v.setWindowTitle("sth")
运行 game.py 结果
__main__.Game
game.Game
<class 'PyQt4.QtGui.QGraphicsView'>
Traceback (most recent call last):
File "/home/abiusx/workspace/borj/trunk/game.py", line 119, in <module>
Game.start()
File "/home/abiusx/workspace/borj/trunk/game.py", line 66, in start
map=Map()
File "/home/abiusx/workspace/borj/trunk/map.py", line 16, in __init__
v.setWindowTitle("asb")
TypeError: QWidget.setWindowTitle(QString): first argument of unbound method must have type 'QWidget'
问题是,map.py 中引用 Game.View 的代码将其检测为一个类(如在类主体中定义的那样),而不是被覆盖的内容(实际实例)。Game 在 game.py 中也称为main .Game 但在 map.py 中称为 game.Game
有人可以帮我吗?
