我测试了这个代码,当双击选项卡时,它会调整选项卡窗格的大小。
tabPane.setOnMouseClicked(new EventHandler<MouseEvent>()
{
private double sizeX, sizeY;
private boolean first = true;
@Override
public void handle(MouseEvent me)
{
if (first)
{
sizeX = mainPane.getWidth();
sizeY = mainPane.getHeight();
first = false;
}
if (me.getButton().equals(MouseButton.PRIMARY) && me.getClickCount() % 2 == 0)
{
if (sizeX != mainPane.getWidth() || sizeY != mainPane.getHeight())
{
mainPane.setPrefSize(sizeX, sizeY);
}
else
{
mainPane.setPrefSize(primaryScreenBounds.getWidth(), primaryScreenBounds.getHeight());
}
}
}
});
当我双击时,我想覆盖主舞台上的所有其他组件。我怎么能这样做?
