qt - 在全屏和窗口模式之间切换

问题描述

我的问题与这个有关：Full-screen desktop application with QML

这是我的 MWE：

import QtQuick 2.11
import QtQuick.Window 2.2
import QtQuick.Controls 2.2

Window
{
    property string windowFull: "FullScreen";
    property string windowWindowed: "Windowed";

    width: 400
    height: 400
    visible: true
    title: "Example"
    visibility: windowFull;
    id: theWindow;

    Button
    {
        onClicked:
        {
            if (theWindow.visibility === windowWindowed)
                theWindow.visibility = windowFull;
            else
                theWindow.visibility = windowWindowed;
        }
    }
}

在此示例中，我尝试在单击按钮时从窗口模式切换到全屏模式，反之亦然。我的问题是从窗口模式进入全屏工作，但从全屏到窗口不工作。为了从全屏进入窗口模式，是否有任何特殊要求？

解决方案

在 Ubuntu 上，使用Window.AutomaticVisibility将窗口可见性设置为窗口（默认窗口）。请检查QML 窗口示例。

import QtQuick 2.11
import QtQuick.Window 2.2
import QtQuick.Controls 2.2

Window
{
    property string windowFull: "FullScreen";
    property string windowWindowed: "Windowed";

    width: 400
    height: 400
    visible: true
    title: "Example"
    visibility: windowFull;
    id: theWindow;

    Button
    {
         onClicked:
        {
            if (theWindow.visibility === Window.FullScreen)
                theWindow.visibility = Window.AutomaticVisibility;
            else
                theWindow.visibility = Window.FullScreen;
        }
    }
}
