从预定义布局将选项卡插入 QTabWidget

Question

我正在尝试动态地向我的 QTabWidget 添加选项卡，我想做的简单事情就是复制我已经拥有的第一个预设选项卡。在你引导我回答这个问题之前：，请听我说完。

我不想手动复制标签。我拥有的选项卡很详细，可以随时对其进行重大更新，我想简单地在 QTDesigner 中编辑它，然后动态复制它或简单地将给定的表单插入 QTabWidget。我已经尝试了很多事情（即：尝试制作一个单独的表单并导入它，设计我自己的标签页 class [有效但不是我想要的]，从字面上复制 tabWidget 并尝试添加它）但其中 none 似乎可以解决问题。

我只需要通过预定义的 UI.

插入一个标签

编辑：

通过 QtDesigner 软件创建表单并将其导出到 python 文件后，我得到以下代码：

    Form = QtWidgets.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

在我的 MainWindow class 中，我从新生成的 python 文件中导入 Ui_Form，该文件包含我想要复制的新选项卡的内容。这就是我卡住的地方..我调用了将为我生成 uild 选项卡的函数：

def buildTabs(self, numberOfTabs): 
    for dut in range(numberOfTabs): 
        text = ('TAB ' + ascii_uppercase[dut]) 
        self.ui.tabWidget.addTab(Ui_Form(), text)

选项卡小部件位于主 window 的 ui 中。

我不明白如何将 Ui_Form() 变成 Ui_TabPage 或

中所示的 QWidget

pyuic生成的文件是形式的classes，其实是标准的pythonobjectclasses，并且他们需要一个 QWidget 实例（或者在 Designer 中用于 ui 的任何 class，例如 QDialog）来“build”他们。

def buildTabs(self, numberOfTabs): 
    for dut in range(numberOfTabs): 
        page = QtWidgets.QWidget()
        page.ui = Ui_Form()
        page.ui.setupUi(page)        
        text = ('TAB ' + ascii_uppercase[dut])
        self.ui.tabWidget.addTab(page, text)

考虑到 PyQt 和 PySide 不能混用，所以如果您使用 PyQt，命令是 pyuic，而使用 PySide，命令是 pyside2-uic。

请注意，如果您需要与选项卡页面进行进一步交互，通常最好将 class 分到它们：

class PageOne(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.ui = Ui_Form()
        self.ui.setupUi(self)

        self.ui.someButton.clicked.connect(self.someFunction)
        # ...

或者更好的是，使用多重继承方法，避免通过 ui“子对象”不断访问 ui 元素：

class PageOne(<b>QtWidgets.QWidget, Ui_Form</b>):
    def __init__(self, parent=None):
        super().__init__(parent)
        <b>self.setupUi(self)</b>

        <b>self.someButton.clicked.connect(self.someFunction)</b>
        # ...

然后：

def buildTabs(self, numberOfTabs): 
    for dut in range(numberOfTabs): 
        <b>page = PageOne()</b>
        text = ('TAB ' + ascii_uppercase[dut])
        self.ui.tabWidget.addTab(page, text)
