How to render a component a certain color

Dear all,

I have written my own custom implementation of the ValueList component. While I can get the component to display balloons when there is an error the color of the component doesn't change to match that of the ballons e.g red for error, yellow for warning.

How can I render the component so that it is either yellow or red?

Many thanks!

Do you mean that the color changes like the param Font which turns yellow when warning,red when error?

Hi Panda,

In your attributes, you must override the AllowMessageBalloon property and return true. This will allow the messaging widget to draw balloons if there are warnings/errors on your component.

In order to change the colour of the component to reflect the current messaging state, the correct GH_Palette enum must be selected prior to drawing the capsule. This is the code that GH_Component uses to determine what palette to draw the capsule in:

Dim palette As GH_Palette = GH_CapsuleRenderEngine.GetImpliedPalette(Owner)
If (palette = GH_Palette.Normal) AndAlso (Not Owner.IsPreviewCapable) Then
palette = GH_Palette.Hidden
End If
Dim capsule As GH_Capsule = GH_Capsule.CreateCapsule(Bounds, palette)
