JavaFX节点未注册鼠标事件 [英] JavaFX Nodes Not Registering Mouse Events

问题描述

我已经准备好把头发拉出来了。我正在研究游戏GUI界面，它有一个由单元网格组成的地图。

I'm ready to pull my hair out over this. I'm working on game GUI interface which has a map consisting of a grid of cells.

单元格网格由StackPane组成，然后由几个层组成ImageViews或Shapes等。

The grid of cells is composed of a StackPane and then several layers inside consisting of either ImageViews or Shapes etc.

整个东西包含在GridPane中，它包含BorderPane的中心元素;

The whole thing is contained in a GridPane, which comprises the center element of a BorderPane;

我不能将鼠标事件添加到底层场景，因为所有节点都得到它 - >没有好处。我需要突出显示鼠标下的节点。

I can't add a mouse event to the underlying scene because then all the nodes get it -> no good. I need to highlight the nodes under the mouse.

这是创建堆栈的代码：

private void initializePanes() {
    myParent = new StackPane();
    myObjectLayer = new StackPane();
    myOverlayLayer = new StackPane();
    myParent.getChildren().addAll(myObjectLayer, myOverlayLayer);
    myParent.getStylesheets().add(myConfig.getString("StyleSheet"));
}

以下是设置EventHandler的代码 - >无效或寄存器。我也试过了EventFilters - 没有骰子，除非我写入底层场景，这是一个禁忌。

and Here's the code to set an EventHandler -> nothing works or registers. I've tried EventFilters too - no dice, not unless I write to the underlying scene, which is a No-Go.

private void initializeHandlers() {
    myParent.addEventHandler(MouseEvent.ANY, (e) -> System.out.println("I'm responding"));  
}

帮助将不胜感激！

编辑：这是问题所在，整个应用程序的布局如下：

EDIT: here's the issue, The overall application is laid out as so:

BorderPane：
中心 - > StackPane
在这个堆栈窗格中我有一个ScrollPane，它包含一个GridPane，其中包含单元格（我在上面发布了代码）。

BorderPane: Center -> StackPane Within that stackpane I have a ScrollPane, which contains a GridPane, which contains the cells (which I posted code for above).

我有点JavaFX的新手，所以这可能不是一个很好的方法。但由于某些原因，鼠标事件不会使它超过底层堆栈窗口 - >即它们被边框的中心面板吸收。我无法将事件处理程序添加到滚动窗格，网格窗格或gridpane中的任何单元格。

I'm somewhat new to JavaFX so maybe this isn't a good way to do this. But for some reason, mouse events do not make it past the underlying stackpane -> i.e. they get absorbed by the center panel of the borderpane. I cannot add event handlers to the scroll pane, the grid pane, or any of the cells within the gridpane.

推荐答案

想出来。
主堆栈窗格中有另一层用于Map - >它正在拦截调用。删除它 - 我会弄清楚如何在以后实现它。

Figured it out. There was another layer in the main stack pane for the Map -> it was intercepting the calls. Removed it - I'll figure out how to implement it later.
