I find that I write a lot of code within my classes to keep properties in sync with each other. I've read about Events in Classes, but have not been able to wrap my head around how to make them work for what I'm looking for. I could use some advice here.
For example, in this one I always want to keep myColor
up to date with any change whatsoever in any or all of the Red
, Green
or Blue
properties.
Class myColors
Private Property Red As Byte
Private Property Green As Byte
Private Property Blue As Byte
Private Property myColor As Color
Sub New()
myColor = Color.FromArgb(0, 0, 0)
End Sub
Sub ChangeRed(ByVal r As Byte)
Red = r
myColor = Color.FromArgb(Red, Green, Blue)
End Sub
Sub ChangeBlue(ByVal b As Byte)
Blue = b
myColor = Color.FromArgb(Red, Green, Blue)
End Sub
End Class
If one or more of those changes, I want myColor
to be updated. Easy enough as above, but is there a way to work with events that would automatically do this so I don't have to put myColor = Color.FromArgb(Red, Green, Blue)
in every sub routine?
