拆分窗口控件QSplitter

QSplitter 是 PyQt6 中用于创建可调整大小的分割窗口的控件，允许用户通过拖动分隔条来调整子部件的大小比例。

from PyQt6.QtWidgets import QApplication, QWidget, QSplitter, QLineEdit, QTextEdit, QHBoxLayout

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

    def ui(self):
        self.setWindowTitle("拆分窗口")
        self.show()

        self.edit3 = QTextEdit()
        self.edit1.setPlaceholderText("edit1")

        self.splitter_windows.setSizes([200, 200, 200])  # 设置拆分窗口的大小
        self.splitter_windows.setOpaqueResize(True)
        h_layout = QHBoxLayout()
