Hi all
I thought I'd give some feedback regarding some recent postings. I had a
table of countries displayed in a grid and I wanted to display a map on
the same form and have the fiill color of the countries change as the
grid row changed. I was looking for a solution to work with a map in
SVG format (although I had the same map in Visio VSS and was prepared to
use that).
Whilst I was still struggling to find an SVG solution, I worked with
Visio and had this in the AfterRowColCange of the grid:
THISFORM.oleControl1.Document.Pages(1).Shapes(TRIM(curShapes.ShapeID)).Cells("FillForegnd").ResultIU
= 4
Works great EXCEPT it was taking 10-11 seconds for the map to be updated
on the form as I moved from row to row !!
Anyway I finally found this
http://esvg.ultimodule.com/bin/esvg/templates/splash.asp?NC=1689X
which is exactly what I needed to work with the SVG from VFP. This is
what I put in the AfterRowColChange
WITH THISFORM.oleControl1
IF NOT EMPTY(THISFORM.LastNode)
loElement = .Document.GetElementByID(THISFORM.LastNode)
loElement.setAttribute("fill", THISFORM.LastNodeColor)
ENDIF
loElement = .Document.GetElementByID(TRIM(curShapes.ShapeID))
THISFORM.LastNode = TRIM(curShapes.ShapeID)
THISFORM.LastNodeColor = loElement.GetAttribute("fill")
loElement.SetAttribute("fill", "green")
ENDWITH
It is blindingly fast - you can hold the downarrow key and the map is
updated as fast as you can go through the grid. Amazing !
Hope somebody might find this useful
Cheers
Paul Newton
