範例
下列程式碼範例會建立 Chart,以及 MouseDown 事件的處理常式,當指標位於圖表上並按下滑鼠按鈕時,會在儲存格 D14 中顯示滑鼠指標的座標。
WithEvents MouseDownChart As Microsoft.Office.Tools.Excel.Chart
Private Sub DisplayMouseDown()
Me.Range("A1", "A5").Value2 = 22
Me.Range("B1", "B5").Value2 = 55
MouseDownChart = Me.Controls.AddChart(Me.Range("D2", "H12"), _
"MouseDownChart")
MouseDownChart.SetSourceData(Me.Range("A1", "B5"), _
Excel.XlRowCol.xlColumns)
MouseDownChart.ChartType = Excel.XlChartType.xl3DColumn
End Sub
Sub MouseDownChart_MouseDown(ByVal Button As Integer, _
ByVal Shift As Integer, ByVal x As Integer, _
ByVal y As Integer) Handles MouseDownChart.MouseDown
Me.Range("D14").Value2 = _
"The chart was clicked at coordinates " _
& x.ToString() & ", " & y.ToString()
End Sub
private void DisplayMouseDown()
{
this.Range["A1", "A5"].Value2 = 22;
this.Range["B1", "B5"].Value2 = 55;
Microsoft.Office.Tools.Excel.Chart chart1 =
this.Controls.AddChart(this.Range["D2", "H12"],
"chart1");
chart1.SetSourceData(this.Range["A1", "B5"],
Excel.XlRowCol.xlColumns);
chart1.ChartType = Excel.XlChartType.xl3DColumn;
chart1.MouseDown +=
new Excel.ChartEvents_MouseDownEventHandler(
chart1_MouseDown);
}
void chart1_MouseDown(int Button, int Shift, int x, int y)
{
this.Range["D14"].Value2 = "The chart was clicked at" +
" coordinates " + x.ToString() + ", " + y.ToString();
