Question

我希望Cell添加JTable Tooltips Cell，其行为类似于Tooltips。我的意思是当鼠标在Tooltip上输入时，它会显示并消失一段时间后（与@Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { final JLabel lable = new JLabel(value.toString()); EdgedBalloonStyle style = new EdgedBalloonStyle(new Color(255, 253, 245), new Color(64, 64, 64)); BalloonTip tooltipBalloon = new BalloonTip(lable, new JLabel(value.toString()), style, new LeftAbovePositioner(15, 10), null); ToolTipUtils.balloonToToolTip(tooltipBalloon, 400, 2000); return lable; }相同但不是@Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { final JLabel lable = new JLabel(value.toString()); EdgedBalloonStyle style = new EdgedBalloonStyle(new Color(255, 253, 245), new Color(64, 64, 64)); TablecellBalloonTip tcb = new TablecellBalloonTip(table, new JLabel(value.toString()), row, column, style, BalloonTip.Orientation.LEFT_ABOVE, BalloonTip.AttachLocation.ALIGNED, 30, 10, false); return lable; }）。我试过这个，但没有按照预期为我工作。

Balloon Tip

这没有做任何事。我也试过这个

{{1}}

这只是作为{{1}}而不是我所寻找的。有什么建议？

我认为问题在于你将你的气球附加到新创建的JLabel上......

...尝试将其添加到您的renderedCellCopmponent：

@Override
public Component getTableCellRendererComponent(JTable table, Object value,
    boolean isSelected, boolean hasFocus, int row, int column) {

    final JLabel lable = new JLabel(value.toString());

    EdgedBalloonStyle style = new EdgedBalloonStyle(new Color(255, 253, 245), new Color(64, 64, 64));

    //look, here is your mistake: you append it onto a new JLabel
    //TablecellBalloonTip tcb = new TablecellBalloonTip(table, 
    //     new JLabel(value.toString()), row, column, style, 
    //      BalloonTip.Orientation.LEFT_ABOVE,
    //      BalloonTip.AttachLocation.ALIGNED, 30, 10, false);

    //instead append it on your rendered Component
    TablecellBalloonTip tcb = new TablecellBalloonTip(table, 
        lable, // !!here!!
        row, column, style, BalloonTip.Orientation.LEFT_ABOVE,
        BalloonTip.AttachLocation.ALIGNED, 30, 10, false);

    return lable;
}

我希望有效...
