| re: How do I prevent appearance inheritance?
In the Paint Event:
Private Sub uc3DPanel_Paint(ByVal sender As Object, ByVal e As
System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
Dim rec As Rectangle = New Rectangle(3, 3, Me.Width - 6,
Me.Height - 6)
Dim myBrush As Brush = New Drawing2D.LinearGradientBrush(rec,
GradientColor1, GradientColor2, GradientT)
Select Case miDrawstyle
Case 1
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.Bump)
Case 2
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.Etched)
Case 3
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.Flat)
Case 4
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.Raised)
Case 5
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.RaisedInner)
Case 6
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.RaisedOuter)
Case 7
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.Sunken)
Case 8
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.SunkenInner)
Case 9
ControlPaint.DrawBorder3D(e.Graphics, ClientRectangle,
Border3DStyle.SunkenOuter)
End Select
If UseGradients = True Then
e.Graphics.FillRectangle(myBrush, rec)
End If
myBrush = Nothing
End Sub
I solved the inheritance problem (kind of) by drawing the gradient
last. If I draw the gradient first and then apply the border, every
control placed in the panel has that border. I also had to reduce the
area drawn by the gradient because it would erase the border.
However, it's a nifty accidental feature cause at 3 pixels or more, it
retains the border and allows the true BackColor to come through as a
seondary inside border.
The only real problem left is that in design view, if you change a
color, the change doesn't appear. I have to switch to code view then
back to design to see the change. Don't know why or where to begin
with that one.
I'll post the entire source if I can get this figured out. I'd still
like to know how to disable visual inheritance tho.
