PyQt4轉換ui檔案為py檔案
阿新 • • 發佈：2019-01-14
1.轉換ui為py
.py檔案是這樣生成的：
在cmd控制檯下,進入uic目錄:
cd C:\Users\MVTECH\Anaconda3\Lib\site-packages\PyQt4\uic輸入命令：
python pyuic.py "ui檔案路徑" -o "py檔案路徑"完成以上操作以後會生成.py檔案，以下為示例程式碼：

注意：還沒結束，這個時候你執行.py檔案不會出錯，但是也不會出現介面，要想執行出界面還需另外新增程式碼。
2.轉換後的py檔案還不能執行，需要視覺化操作才可執行。
有兩種方法：
第一種方法：直接在生成的.py檔案的後面新增以下程式碼：
class MainWindow(QtGui.QWidget): def __init__(self,parent=None): QtGui.QWidget.__init__(self,parent) self.ui = Ui_Form() self.ui.setupUi(self) if __name__ == "__main__": app = QtGui.QApplication(sys.argv) myapp = MainWindow() myapp.show() app.exec_()
第二種方法：在同目錄下新建Main.py，根據設計UI時選擇視窗型別填寫指令碼內容
如圖，圖中根視窗類名（此處為QWidget）物件名（此處為Form），即如下填寫：
# -*- coding: utf-8 -*- """ Created on Thu Sep 6 09:47:12 2018 @author: MVTECH """ from PyQt4 import QtGui from ECGMachineLearning import * import sys class MainWindow(QtGui.QWidget): def __init__(self,parent=None): QtGui.QWidget.__init__(self,parent) self.ui = Ui_Form() self.ui.setupUi(self) if __name__ == "__main__": app = QtGui.QApplication(sys.argv) myapp = MainWindow() myapp.show() app.exec_()
其他類似視窗只需替換程式碼中的紅色和藍色部分為視窗例項類名、物件名即可！！！
注意：像Dialog這樣的視窗還需要在MainWindow中實現accept()（確認）和reject()（取消）函式，自己融會貫通即可！！！
