it seems there are still issues:
1. where did you get this service from? at least this is completely new to me
[sample code attached], and AFAIK there is no com.sun.star.drawing.ColorTable
in the API reference.
2. Could you make your changes in the color palette persist after your object
dies?
Try the following:
Sub Main
Dim oColorTable as Object
oColorTable = CreateUnoService("com.sun.star.drawing.ColorTable")
Dim sNewName$, bHas as Boolean
sNewName = "My New Color"
If NOT oColorTable.hasByName(sNewName) Then
oColorTable.insertByName(sNewName, RGB(0,124,197))
bHas = oColorTable.hasByName(sNewName)
End If
End Sub
The first time you run the macro, the condition evaluates to false, so you
insert a new color and bHas returns true, saying this went OK.
The second time you run the macro, the condition should evaluate to true, as
you already inserted a new color with that name; but this is not the case,
changes are not made persistent.
This is because the implementation of SvxUnoColorTable
http://svn.services.openoffice.org/opengrok/xref/DEV300_m42/svx/source/unodraw/unoctabl.cxx
misses the point that changes to the XColorTable must be saved for them to
really take place... well, at least this is what the color tab page does
invoking XColorTable::Save().
