Question

我想在主窗口后显示的表单后显示表单。

这是我的代码。我在mainwindow之后成功显示表单。

但MainWindow-＆gt; Form-＆gt;表单不起作用....

请帮助我的大脑

我的大脑很热......

main.py

class main(QtGui.QMainWindow):
def __init__(self,parent=None):
    QtGui.QWidget.__init__(self,parent)
    self.ui=Ui_MainWindow()
    self.ui.setupUi(self)        
app=QtGui.QApplication(sys.argv)
myapp=main()
myapp.show()
app.exec_()

你应该连接功能。

你打电话给其他表格

如果您只想调用一次Form，请删除帖子。

def create_setting(self):
    global Dialog     
    Dialog=QtGui.QDialog()
    thread.start_new_thread(start,(Dialog,))
    child = settingUI.Ui_Form()
    child.setupUi(Dialog)
    Dialog.setWindowFlags(Dialog.windowFlags()|QtCore.Qt.WindowSystemMenuHint|QtCore.Qt.WindowMinMaxButtonsHint)
    Dialog.show()

Pyqt4 MainWindow-＆gt; Form-＆gt;表格不可能？
