[英]C# Image RollOver
問候,即時通訊試圖在一個PictureBox集合上實現圖像翻轉,該PictureBox集合放置在tablelayoutpanel中,每個表格單元格中一個。
這是我的代碼:
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);
}
}
但結轉無效! 關於如何正確實現這一點的任何想法?
提前致謝。
下列:
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);
}
它會向右滾動圖像,但不顯示工具提示。 如果我在工具提示上聲明HomeCurrentPicBox而不是HomeTableLayoutPanel,則會顯示錯誤。
好吧不行,我認為。 我不得不更改工具提示的AutomaticDelay值。
感謝大家。
以下應該工作:
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";
}
編輯:請注意,我正在使用ImageLocation更改圖片,可以使用任何您喜歡的東西,可以使用'Image'屬性代替ImageLocation並根據需要為其分配圖像。
