• layout 공통 사항

 

 layout_group.addStretch(1)                        #--- 레이아웃 내부 정렬
 layout.setStretchFactor(layout_left, 1)           #--- 레이아웃 상대 크기 지정
 layout.setStretchFactor(layout_right, 3)          #--- 레이아웃 상대 크기 지정

 

• QVBoxLayout, QHBoxLayout

 

        self.setCentralWidget(QtWidgets.QWidget(self))
 
        self.textEdit = QTextEdit()
        self.pushButton = QPushButton('저장')
 
        layout = QVBoxLayout()
        layout = QHBoxLayout()
        layout.addWidget(self.textEdit)
        layout.addWidget(self.pushButton)
        # self.setLayout(layout)
        self.centralWidget().setLayout(layout)

 

• QGridLayout

 

        self.setCentralWidget(QtWidgets.QWidget(self))
 
        layout = QGridLayout()
        layout.addWidget(QLabel("아이디"), 0, 0)
        layout.addWidget(QTextEdit(), 0, 1)
        layout.addWidget(QPushButton('로그인'), 0, 2)
 
        layout.addWidget(QLabel("비밀번호"), 1, 0)
        layout.addWidget(QTextEdit(), 1, 1)
 
        self.centralWidget().setLayout(layout)

 

• QFileDialog, QInputDialog

 

        fname = QFileDialog.getOpenFileName(self)
        fname[0](0.md)
 
        (rtInt, ok) = QInputDialog.getInt(self, '수량', '수량을 입력 하세요.')    #--- ~.getDouble()
        if ok:
            rtInt
 
        (rtStr, ok) = QInputDialog.getText(self, '이름', '이름을 입력 하세요.')
        if ok:
            rtStr
 
        (rtStr, ok) = QInputDialog.getItem(self, '이름', '이름을 선택 하세요.', 
                                           ['홍길동', '유관순']('이순신',), 0, False)
        if ok:
            rtStr

 

• 사용자 정의 Dialog

 

    def show_dialog(self):
        dlg = MyDialog()
        dlg.exec_()
        
        print(dlg.name)
 
 class MyDialog(QDialog):
    def __init__(self):
        super.__init__()
        self.name = None
         
        self.setWindowTitle("My Dialog")
        self.setWindowIcon(QIcon("~.png"))
        self.setGeometry(100, 100, 200, 200)
         
        self.edit = QLineEdit()
        self.button = QPushButton("아이디 확인")
        self.button.clicked.connect(self.button_clicked)
 
        layout = QVBoxLayout()
        layout.addWidget(self.edit)
        layout.addWidget(self.button)
        self.setLayout(layout)
 
    def button_clicked(self):
        self.name = self.edit.text()
        self.close()

 

• FigureCanvas

 

        self.canvas = FigureCanvas(plt.Figure())                                #--- Canvas > Figure > Subplot
        self.canvas.figure.clear()                                              #--- Figure 지우기
        self.ax = self.canvas.figure.add_subplot(1, 1, 1)
 
        self.ax.plot([2, 3, 4, 3](1,))
        self.ax.grid()
 
        self.ax.clear()                                                         #--- Subplot 지우기
