TornadoFx Undecorated window 从任务栏恢复时进入全屏
TornadoFx Undecorated window goes fullscreen when restored from task bar
我一直在试用 Tornadofx。尝试创建自定义 title-bar,这是我目前正在尝试的代码
fun main(args: Array<String>) {
launch<MyApp>(args)
}
class MyApp : App(Title::class) {
override fun start(stage: Stage) {
stage.initStyle(StageStyle.UNDECORATED)
stage.minWidth = 600.0
stage.minHeight = 450.0
stage.isMaximized = false
super.start(stage)
}
}
class Title : View() {
private var xOffset = 0.0
private var yOffset = 0.0
private var screenBounds: Rectangle2D = Screen.getPrimary().visualBounds
private var originalBounds: Rectangle2D = Rectangle2D.EMPTY
init {
primaryStage.isMaximized = false
}
override val root = borderpane {
onMousePressed = EventHandler { ev ->
xOffset = primaryStage.x - ev.screenX
yOffset = primaryStage.y - ev.screenY
}
onMouseDragged = EventHandler { ev ->
primaryStage.x = xOffset + ev.screenX
primaryStage.y = yOffset + ev.screenY
}
center = label("Forms")
right = hbox {
button("Mi") {
action {
with(primaryStage) { isIconified = true }
}
}
button("Ma") {
action {
if (primaryStage.isMaximized) {
with(primaryStage) {
x = originalBounds.minX
y = originalBounds.minY
width = originalBounds.width
height = originalBounds.height
isMaximized = false
}
text = "Ma"
} else {
with(primaryStage) {
originalBounds = Rectangle2D(x, y, width, height)
x = screenBounds.minX
y = screenBounds.minY
width = screenBounds.width
height = screenBounds.height
isMaximized = true
}
text = "Re"
}
}
}
button("X") {
action {
app.stop()
println("exiting")
exitProcess(0)
}
}
}
}
}
以下工作没有问题
- 关闭
- 最大化,恢复
- 恢复window最小化,然后从任务栏打开
但是当最大化的 window 最小化到任务栏,然后从任务栏打开时,它会全屏(隐藏任务栏)
我该如何解决这个问题,我的代码是否有任何错误、需要更改或需要包含的部分?
我的配置是 Windows 10 64 位,Java 11.0.2,Kotlin 1.4.21,JavaFx 11.0.2,TornadoFx 1.7.20
我认为这是 JavaFX 中的普遍问题(我的意思是不特定于 TornadoFX)。
根本原因是因为将舞台的maximized 属性设置为true。不确定 JavaFX 内部做了什么,但是当您从任务栏打开 window 并且如果最大值为真时,它会以全屏模式呈现。
您可以通过两种方式解决此问题。
方法 #1:
当从任务栏打开 window 时,图标 属性 将关闭,如果最大化为真,请将舞台尺寸再次设置为屏幕边界。
primaryStage.iconifiedProperty().addListener((obs,old,iconified)->{
if(!iconified && primaryStage.isMaximized()){
primaryStage.setWidth(screenBounds.getWidth());
primaryStage.setHeight(screenBounds.getHeight());
}
});
方法 #2:
不要依赖舞台的最大化 属性。我相信您需要 属性 来切换 window 维度。因此,改为维护一个实例变量来处理它。
boolean maximized = false;
ma.setOnAction(e -> {
if (maximized) {
// Set stage to original bounds
maximized = false;
ma.setText("Ma");
} else {
// Set stage to screen bounds
maximized = false;
ma.setText("Re");
}
});
下面是这两种方法的完整工作演示。您可以根据您的其他需求决定走哪条路。

解决问题需要进行两项更改
实际问题是,如果 isMaximized 设置为 true,即使 isFullScreen 属性 单独可用,应用程序在从任务(最小化)打开时会全屏显示
- 添加一个最大化的 属性 侦听器,这样我们就可以在 isMaximized 被其他方式修改时无效(比如双击 Linux 中的标题栏等)
// CHANGE 1
stage.maximizedProperty().addListener { _, _, newValue ->
if (newValue) stage.isMaximized = false
}
- 通过单独最大化而不是使用 isMaximized
// CHANGE 2
private var maximized: Boolean = false // <- here
if (maximized) { // <- here
// restore the window by setting bounds of original size
maximized = false // <- here
text = "Ma"
} else {
// maximize window by setting bounds from screen size
maximized = true // <- and here
text = "Re"
}
