如果程序已最大化，我将其最小化，然后单击回到程序，它是否处于窗口模式？
if the program is maximized and I minimize it and then click back to the program it is in windowed mode?
我的程序在 默认情况下以 windowed 模式启动 。
我的问题是，如果我 启动它 然后 按最大化 ，然后 最小化 然后 在任务栏中单击它，它处于window编辑模式并且未最大化。
老实说，我制作了这个全新的 window 因为我喜欢设计清晰的程序。我不知道你能不能改变一个普通的Window的顶部，比如关闭按钮的图标或者它的颜色。

这里有一个解决这个问题的 hacky 方法：
将 property int saved_state 添加到您的 ApplicationWindow
然后添加以下代码：
onVisibilityChanged: {
if(saved_state === 4 && visibility === 2) {
showMaximized()
saved_state = -1
}
}
然后在您的 MouseArea minimize_sindowMouseArea 旁边添加以下行：
saved_state = mainWindow.visibility //NEW LINE
mainWindow.visibility = "Minimized" //Existing line
说明：保存你的window在你最小化之前的状态，然后在恢复时恢复到save_state。
我不知道有什么更干净的方法，但应该这样做 :)
我的程序在 默认情况下以 windowed 模式启动 。
我的问题是，如果我 启动它 然后 按最大化 ，然后 最小化 然后 在任务栏中单击它，它处于window编辑模式并且未最大化。
