Model_Dialog 在進行其他部分操作之前坠狡，必須完成目前操作泵三，可能是問題信息咽安，警告伴网，不安全的更改，選擇文件等等

大綱到視圖的操作是一個 un_Model_Dialog 非模式對話框妆棒， 直接能切換

custom_dialog

• 一個line_edit 輸入文本是偷，ok_btn 打印一下輸入的文本

class CustomDialog(QtWidgets.QDialog):

    def __init__(self, parent=get_maya_main_window()):
        super(CustomDialog, self).__init__(parent)

        self.setWindowTitle('Custom Dialog UI')

    def create_widgets(self):

        btn_layout.addStretch()
        btn_layout.addWidget(self.btn_ok)

        main_layout = QtWidgets.QVBoxLayout(self)
        main_layout.addLayout(line_layout)
        main_layout.addLayout(btn_layout)

        self.btn_ok.clicked.connect(self.accept)

    # ___Slots___

    def get_text(self):
        return(self.line_edit.text())

有四個按鈕的 Dialog

• waring 使用 QMessageBox.waring 彈出警告信息
• folder_select 使用 QFileDialog.getExsitingDirectory() 文件對話框 得到存在的文件夾路徑
• color_select 使用 QtGui.QColor 先定義好一個顏色， 使用QtWidgets.QColorDialog.getColor() 顏色對話框, 獲取顏色募逞，打印出來
• custom_dialog 實例化CustomDialog(), 執(zhí)行狀態(tài)蛋铆， 然后是執(zhí)行狀態(tài)是接受，打印文本信息
