我有一个类,我需要访问它的属性。问题在于此类的实例在另一个类中实例化。
这是我希望访问其变量的类(还有更多内容,但是这会显示如何创建类):
class Button(QtGui.QPushButton):
def __init__(self, iconPathUnassigned, iconX, iconY, posX, posY, posA, posB, objName, labEdit, iconPathAssigned, iconPathPlaying, parent=None):
super(Button, self).__init__(parent=parent)
self.setAcceptDrops(True)
self.iconPathAssigned = iconPathAssigned
然后在另一个类中实例化该类:
class Ui_Form(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
self.setupUi(self)
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(591, 591)
self.btn_a1 = Button("Python/LP_Proj/LP_Circle_Off.png", 49, 49, 30, 38, 41, 41, "btn_a1", self.lab_a1, "Python/LP_Proj/LP_Circle_Green.png", "Python/LP_Proj/LP_Circle_Red.png", self)
类Ui_Form
按以下方式创建:
if __name__=='__main__':
app = QtGui.QApplication(sys.argv)
ex = Ui_Form()
ex.show()
sys.exit(app.exec_())
所以,说我想在行iconPathAssigned
之后打印btn_a1
ex.show()
变量,我该怎么做?我尝试了各种各样的方法:
print Ui_Form.btn_a1.iconPathAssigned
print Form.btn_a1.iconPathAssigned
print btn_a1.iconPathAssigned
print QtGui.QWidget(Ui_Form.btn_a1.iconPathAssigned)
答案 0 :(得分:3)
ex
因为ex = Ui_Form()
是您的表单实例(正如您从finish()
行所知道的那样)
