在PyQt5中单击按钮时关闭自定义输入对话框
在PyQt5中单击按钮时关闭自定义输入对话框
提问于 2019-06-05 00:12:02
我已经创建了一个自定义的搜索对话框，只有很少的输入字段和两个按钮，比如“提交”和“关闭”。在按下关闭时，我想关闭对话窗口并返回父窗口，类似地，在提交时，我可以过滤数据，对话框保持活动状态，在这两种情况下，我都想关闭对话窗口，我该如何做，请帮助.
示例主窗口
from PyQt5 import QtCore, QtGui, QtWidgets
from search_dialog import Ui_Dialog
import sys
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800, 600)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(240, 150, 75, 23))
self.pushButton.setObjectName("pushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 21))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.pushButton.clicked.connect(self.open_dialog)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
def retranslateUi(self, MainWindow):
_translate = QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
self.pushButton.setText(_translate("MainWindow", "PushButton"))

MainWindow = QtWidgets.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())搜索对话框

您必须将按钮连接到插槽QDialog::reject()和QDialog::accept()。
您可以在您的方法setupUi中完成此操作
class Ui_Dialog(object):
def setupUi(self, Dialog):
...
self.pushButton_2.clicked.connect(Dialog.reject)
self.pushButton.clicked.connect(Dialog.accept)您还可以使用QDialog::exec()而不是QDialog::show来使您的对话框成为模态对话框，并在关闭对话框时直接获得结果。
