阻止命令栏进入横向模式

from PyQt5.QtWidgets import QApplication, QMainWindow, QToolBar

app = QApplication([])
window = QMainWindow()
toolbar = QToolBar()
window.addToolBar(toolbar)

# 设置工具栏的方向为垂直
toolbar.setOrientation(Qt.Vertical)

window.show()
app.exec_()

using System;
using System.Windows.Forms;

public class MainForm : Form {
    protected override void OnLoad(EventArgs e) {
        base.OnLoad(e);
        SystemEvents.DisplaySettingsChanged += new EventHandler(SystemEvents_DisplaySettingsChanged);
    }

    private void SystemEvents_DisplaySettingsChanged(object sender, EventArgs e) {
        // 重新设置布局
        this.SuspendLayout();
        // ... 调整控件布局的代码 ...
        this.ResumeLayout();
    }
}

@media screen and (orientation: landscape) {
    /* 在横向模式下应用的样式 */
    .toolbar {
        width: 100%;
        flex-direction: column;
    }
}

@media screen and (orientation: portrait) {
    /* 在纵向模式下应用的样式 */
    .toolbar {
        width: auto;
        flex-direction: row;
    }
}
