C＃Image RollOver

Question

问候，我试图在tablelayoutpanel中放置的PictureBox集合和每个表格单元格中的一个上实现图像翻转。

这是我的代码：

HomePicBox[picBoxCount].MouseEnter += new System.EventHandler(this.PictureBox_MouseEnter);

HomePicBox[picBoxCount].MouseLeave += new System.EventHandler(this.PictureBox_MouseLeave);

==================

    private void PictureBox_MouseEnter(object sender, EventArgs e)
    {
        Point p = HomeTableLayoutPanel.PointToClient(Control.MousePosition);
        PictureBox HomeCurrentPicBox = (PictureBox)(HomeTableLayoutPanel.GetChildAtPoint(p));

        if (HomeCurrentPicBox == null)
            return;

        TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox);

        if (GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row) == Cell.cellState.Water)
        {
            HomeCurrentPicBox.Image = Properties.Resources.Scan;
            HomeCurrentPicBox.Refresh();

            gameFormToolTip.SetToolTip(HomeCurrentPicBox, GameModel.alphaCoords(HomeCurrentPosition.Column) + "," + HomeCurrentPosition.Row);

        }
    }

    private void PictureBox_MouseLeave(object sender, EventArgs e)
    {
        Point p = HomeTableLayoutPanel.PointToClient(Control.MousePosition);
        PictureBox HomeCurrentPicBox = (PictureBox)(HomeTableLayoutPanel.GetChildAtPoint(p));

        if (HomeCurrentPicBox == null)
            return;

        TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox);

        if (GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row) == Cell.cellState.Water)
        {
            HomeCurrentPicBox.Image = Properties.Resources.Water;
            HomeCurrentPicBox.Refresh();

            gameFormToolTip.SetToolTip(HomeCurrentPicBox, GameModel.alphaCoords(HomeCurrentPosition.Column) + "," + HomeCurrentPosition.Row);
        }
    }

但翻滚无效！关于如何正确实现这一点的任何想法？

提前感谢。

以下内容：

    private void PictureBox_MouseEnter(object sender, EventArgs e)
    {
        PictureBox HomeCurrentPicBox = ((PictureBox)(sender));
        HomeCurrentPicBox.Image = Properties.Resources.Scan;

        TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox);
        gameFormToolTip.SetToolTip(HomeTableLayoutPanel, GameModel.alphaCoords(HomeCurrentPosition.Column) + "," + HomeCurrentPosition.Row);
    }

    private void PictureBox_MouseLeave(object sender, EventArgs e)
    {
        PictureBox HomeCurrentPicBox = ((PictureBox)(sender));
        HomeCurrentPicBox.Image = Properties.Resources.Water;

        TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox);

        gameFormToolTip.SetToolTip(HomeTableLayoutPanel, GameModel.alphaCoords(HomeCurrentPosition.Column) + "," + HomeCurrentPosition.Row);
    }

它会对图像进行翻转，但不会显示工具提示。如果我在工具提示中声明HomeCurrentPicBox而不是HomeTableLayoutPanel它会错误地显示。

好吧，我认为不行。我不得不更改工具提示的AutomaticDelay值。

谢谢大家。

以下应该有效：

    private void pictureBox1_MouseEnter(object sender, EventArgs e)
    {
        ((PictureBox)sender).ImageLocation = "Resources/logo.png";
    }

    private void pictureBox1_MouseLeave(object sender, EventArgs e)
    {
        ((PictureBox)sender).ImageLocation = "Resources/logoonly.png";
    }

编辑：请注意，我使用ImageLocation更改图片，您可以使用任何您喜欢的内容，您可以使用“图像”属性而不是ImageLocation，并根据需要为其指定图像。
