[Python] PyQT5 기본템플릿비교(Widget, Dialog, Main Window)

QT Desinger를 보면 뭐가 많다. 뭐가 다른지 모르겠어서 그냥 코드를 봤다.

 

1. 대충 정리

결론적으로 말하면 Application Object가 다를 뿐이다.

QtWidgets.QWidget() # Widget
QtWidgets.QDialog() # Dialog
QtWidgets.QMainWindow() # Main Window

 

 

2. 조금 설명

Widget, Dialog, Main Window 모두 Widget이다. Main Windows는 상태바랑 메뉴바 같은 걸 넣을 수 있어 말그대로 Win32 API로 Application 만드는 거랑 똑같다고 보면 되겠고, Widget이랑 Dialog는 비슷하지만 Dialog가 좀더 Top-Level이래... 이건 구글링해봐야 자세히 적을 듯

 

 

3. 코드를 보자

PyQT에서 Widget / Dialog / Main Window 뭐가 다른지 몰라서 일단 ui파일을 python으로 변환해서 보자

 

Widget

# -*- coding: utf-8 -*-
from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(431, 241)
        self.addBtn = QtWidgets.QPushButton(Form)
        self.addBtn.setGeometry(QtCore.QRect(350, 10, 75, 23))
        self.addBtn.setObjectName("addBtn")
        self.textBox = QtWidgets.QLineEdit(Form)
        self.textBox.setGeometry(QtCore.QRect(10, 10, 331, 20))
        self.textBox.setObjectName("textBox")
        self.textList = QtWidgets.QListView(Form)
        self.textList.setGeometry(QtCore.QRect(10, 40, 331, 192))
        self.textList.setObjectName("textList")
        self.exitBtn = QtWidgets.QPushButton(Form)
        self.exitBtn.setGeometry(QtCore.QRect(350, 40, 75, 191))
        self.exitBtn.setObjectName("exitBtn")

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "This is Widget"))
        self.addBtn.setText(_translate("Form", "ADD"))
        self.exitBtn.setText(_translate("Form", "EXIT"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    Form = QtWidgets.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

 

Dialog

# -*- coding: utf-8 -*-
from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_Dialog(object):
    def setupUi(self, Dialog):
        Dialog.setObjectName("Dialog")
        Dialog.resize(429, 241)
        self.addBtn = QtWidgets.QPushButton(Dialog)
        self.addBtn.setGeometry(QtCore.QRect(350, 10, 75, 23))
        self.addBtn.setObjectName("addBtn")
        self.textBox = QtWidgets.QLineEdit(Dialog)
        self.textBox.setGeometry(QtCore.QRect(10, 10, 331, 20))
        self.textBox.setObjectName("textBox")
        self.testList = QtWidgets.QListView(Dialog)
        self.testList.setGeometry(QtCore.QRect(10, 40, 331, 192))
        self.testList.setObjectName("testList")
        self.exitBtn = QtWidgets.QPushButton(Dialog)
        self.exitBtn.setGeometry(QtCore.QRect(350, 40, 75, 191))
        self.exitBtn.setObjectName("exitBtn")

        self.retranslateUi(Dialog)
        QtCore.QMetaObject.connectSlotsByName(Dialog)

    def retranslateUi(self, Dialog):
        _translate = QtCore.QCoreApplication.translate
        Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
        self.addBtn.setText(_translate("Dialog", "ADD"))
        self.exitBtn.setText(_translate("Dialog", "EXIT"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    Dialog = QtWidgets.QDialog()
    ui = Ui_Dialog()
    ui.setupUi(Dialog)
    Dialog.show()
    sys.exit(app.exec_())

 

Main Window

# -*- coding: utf-8 -*-
from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(430, 244)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.addBtn = QtWidgets.QPushButton(self.centralwidget)
        self.addBtn.setGeometry(QtCore.QRect(350, 10, 75, 23))

        self.exitBtn.setGeometry(QtCore.QRect(350, 40, 75, 191))
        self.exitBtn.setObjectName("exitBtn")
        MainWindow.setCentralWidget(self.centralwidget)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
