好吧,這是一個幾天來一直困擾我的問題。我試圖從MainWindow打開一個Ui_form。出於某種原因,子窗口會立即打開和關閉。從PyQt的主窗口中打開Ui_Form
class Ui_MainWindow(QtGui.QMainWindow):
def __init__(self,parent=None):
QtGui.QMainWindow.__init__(self,parent)
def setupUi(self, MainWindow):
# Some Gui Code
MainWindow.setObjectName(_fromUtf8("MainWindow"))
MainWindow.resize(406, 234)
self.centralwidget = QtGui.QWidget(MainWindow)
self.centralwidget.setObjectName(_fromUtf8("centralwidget"))
self.verticalLayout = QtGui.QVBoxLayout(self.centralwidget)
self.verticalLayout.setObjectName(_fromUtf8("verticalLayout"))
self.horizontalLayout = QtGui.QHBoxLayout()
self.horizontalLayout.setObjectName(_fromUtf8("horizontalLayout"))
self.listView = QtGui.QListView(self.centralwidget)
self.listView.setObjectName(_fromUtf8("listView"))
self.horizontalLayout.addWidget(self.listView)
self.pushButton = QtGui.QPushButton(self.centralwidget)
self.pushButton.setObjectName(_fromUtf8("pushButton"))
self.horizontalLayout.addWidget(self.pushButton)
self.verticalLayout.addLayout(self.horizontalLayout)
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtGui.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 406, 21))
self.menubar.setObjectName(_fromUtf8("menubar"))
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtGui.QStatusBar(MainWindow)
self.statusbar.setObjectName(_fromUtf8("statusbar"))
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QObject.connect(self.pushButton , QtCore.SIGNAL("clicked()") , self.NewLog)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
MainWindow.setWindowTitle(QtGui.QApplication.translate("MainWindow", "MainWindow", None, QtGui.QApplication.UnicodeUTF8))
self.pushButton.setText(QtGui.QApplication.translate("MainWindow", "New Log", None, QtGui.QApplication.UnicodeUTF8))
def NewLog(self):
app = QtGui.QWidget()
myapp = new_application_log.Ui_Form()
myapp.setupUi(app)
myapp.show()
#app.exec_()
class Ui_Form(QtGui.QWidget):
def __init__(self,parent = None):
QtGui.QWidget.__init__(self,parent)
def setupUi(self, Form):
# Some Gui Code.
Form.setObjectName(_fromUtf8("Form"))
Form.resize(312, 269)
self.verticalLayout = QtGui.QVBoxLayout(Form)
self.verticalLayout.setObjectName(_fromUtf8("verticalLayout"))
self.listView = QtGui.QListView(Form)
self.listView.setObjectName(_fromUtf8("listView"))
self.verticalLayout.addWidget(self.listView)
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
Form.setWindowTitle(QtGui.QApplication.translate("Form", "Form", None, QtGui.QApplication.UnicodeUTF8))
def main():
app = QtGui.QApplication(sys.argv)
MainWindow = QtGui.QMainWindow() # <-- Instantiate QMainWindow object.
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
app.exec_()
看起來這之前只是一個範圍問題。你能發佈一些可用的代碼嗎?您可以嘗試創建變量,將您的新UI窗體設置爲主窗口類中的某處,這樣,當NewLog函數作爲快速修復而退出時,它不會超出範圍 – user3591723
儘管這並不完全必要爲什麼我想看看你是如何使用該代碼。現在它實際上並沒有對新表單做任何事情 – user3591723
@ user3591723:我已經添加了一些可能對您有幫助的代碼,但它不是整個代碼。希望能幫助到你。 – TheCreator232
