当我有一个透明的 SplitPane 时,设置 pickOnBounds=false 不起作用,我无法单击 splitpane 后面的按钮。我有一个带有透明 VBox 的 splitPane,pickOnBounds=false 我还使用 pickOnBounds=false 设置了 splitpane,但是鼠标单击不会通过它们下方的按钮。
我在顶部有一个按钮,部分被 SplitPane 覆盖,底部有一些按钮可以打开/关闭鼠标透明度和 pickOnBounds。
当'Enable MouseTransparency'未选中,并且'Enable Pick On Bounds'未选中时,你应该可以点击SplitPane后面的按钮,但你不能。应用程序的图像
难道是Splitpane的skinclass没有继承pickOnBounds设置???
这是说明问题的示例代码:

import javafx.scene.layout.VBox;
import javafx.stage.Stage;
// Demonstrates the JavaFX node mouseTransparent and pickOnBounds properties.
// shows that 'PickOnBounds=false' does not work for a SplitPane that has a transparent background and you want mouseclicks to go thru
