IDA Python + Qt。如何将自己的选项卡插入到IDA主选项卡小部件中？

from PyQt5.QtWidgets import QWidget, QVBoxLayout
from PyQt5.QtGui import QIcon
from idaapi import PluginForm

class MyTabClass(PluginForm):
    def OnCreate(self, form):
        self.parent = self.FormToPyQtWidget(form)
        layout = QVBoxLayout()
        # 在这里添加自定义的控件和布局
        self.parent.setLayout(layout)

    def OnClose(self, form):
        pass

    def Show(self):
        return PluginForm.Show(self, "My Tab", options=(PluginForm.WOPN_TAB | PluginForm.WOPN_MENU))

def PLUGIN_ENTRY():
    return MyTabClass()

if __name__ == '__main__':
    from idaapi import *
    PLUGIN_NAME = "My Plugin"
    PLUGIN_HOTKEY = "Alt+F8"
    PLUGIN_COMMENT = "This is my plugin"
    PLUGIN_HELP = "https://example.com/my_plugin"
    register_plugin_t(PLUGIN_NAME, PLUGIN_COMMENT, PLUGIN_HELP, PLUGIN_HOTKEY, PLUGIN_ENTRY)
