| Color | A color expression that defines the node's foreground color. |
Use the ForeColor property to specify the node's foreground color. Use the ForeColorNode property to define the default foreground color for nodes. Use the ClearForeColor method to clear the node's foreground color. Use the ForeColor property to specify the control's foreground.
The following VB sample changes the background and foreground color for the selected node:
Private Sub ChartView1_Select(ByVal OldNode As EXORGCHARTLibCtl.INode, ByVal NewNode As EXORGCHARTLibCtl.INode)
If Not (OldNode Is Nothing) Then
With OldNode
.ClearBackColor
.ClearForeColor
End With
End If
With NewNode
.ForeColor = vbWhite
.BackColor = vbBlue
End With
End Sub
The following C++ sample changes the background and foreground color for the selected node:
void OnSelectChartview1(LPDISPATCH OldNode, LPDISPATCH NewNode)
{
CNode oldNode( OldNode ); oldNode.m_bAutoRelease = FALSE;
CNode newNode( NewNode ); newNode.m_bAutoRelease = FALSE;
if ( oldNode.m_lpDispatch != NULL )
{
oldNode.ClearBackColor();
oldNode.ClearForeColor();
}
newNode.SetBackColor( RGB(0,0,128) );
newNode.SetForeColor( RGB(255,255,255) );
}
The following VB.NET sample changes the background and foreground color for the selected node:
Private Sub AxChartView1_SelectEvent(ByVal sender As System.Object, ByVal e As AxEXORGCHARTLib._IChartViewEvents_SelectEvent) Handles AxChartView1.SelectEvent
If Not (e.oldNode Is Nothing) Then
With e.oldNode
.ClearBackColor()
.ClearForeColor()
End With
End If
With e.newNode
.ForeColor = ToUInt32(Color.White)
.BackColor = ToUInt32(Color.Blue)
End With
End Sub
where the ToUInt32 function converts a Color expression to OLE_COLOR,
Shared Function ToUInt32(ByVal c As Color) As UInt32
Dim i As Long
i = c.R
i = i + 256 * c.G
i = i + 256 * 256 * c.B
ToUInt32 = Convert.ToUInt32(i)
End Function
The following C# sample changes the background and foreground color for the selected node:
private void axChartView1_SelectEvent(object sender, AxEXORGCHARTLib._IChartViewEvents_SelectEvent e)
{
if ( e.oldNode != null )
{
e.oldNode.ClearBackColor();
e.oldNode.ClearForeColor();
}
e.newNode.BackColor = ToUInt32(Color.Blue);
e.newNode.ForeColor = ToUInt32(Color.White);
}
where the ToUInt32 function converts a Color expression to OLE_COLOR,
private UInt32 ToUInt32(Color c)
{
long i;
i = c.R;
i = i + 256 * c.G;
i = i + 256 * 256 * c.B;
return Convert.ToUInt32(i);
}
The following VFP sample changes the background and foreground color for the selected node:
*** ActiveX Control Event ***
LPARAMETERS oldnode, newnode
If !isnull(oldnode)
With oldnode
.ClearBackColor
.ClearForeColor
EndWith
EndIf
With newnode
.ForeColor = RGB(255,255,255)
.BackColor = RGB(0,0,128)
EndWith
