I assume you are talking about a preview image, such as the star shape shown here:

See the sample scripts lm_star.lua or lm_polygon.lua for details.

As I understand it, you need to add a mesh preview in your dialog definition:

Code: Select all

	d.preview = MOHO.MeshPreview(200, 200)
	l:AddChild(d.preview)

Add an update function that redraws your shape in the preview:

Code: Select all

function LM_PolygonDialog:UpdatePreview()
	local mesh = self.preview:Mesh()
	mesh:Clear()

	local numPoints = self.numPoints:IntValue()
	numPoints = LM.Clamp(numPoints, 3, 20)

	LM_Polygon:BuildPolygon(mesh, numPoints)
	self.preview:CreateShape(true)
	self.preview:Refresh()
end

and call the update function at the appropriate times (when updating widgets, handling messages, etc.):

Code: Select all

		self:UpdatePreview()

Regards, Myles.
