Xailer & OZ Software

Jose,
I have noticed that when importing an ActiveX control not all the methods,
properties and events are listed in the source file. For example when
importing the MapObjectsLT2 component the method Refresh() method is not
mentioned in the .prg file. However, calling this method does not seem to be
a problem, although calling Refresh() does not have any effect. Is this a
problem in Xailer or is the component not 100% oke?
In the case of the Scalebar object I noticed that many properties are not
listed. I have to admit that in the case of the scalebar object Delphi also
has a problem creating a type lib.
Regards,
Stephan

Well, TOcx inherites from TControl, so all TControl members are also in
TOcx, and Refresh() is one of them.
ITOH, Xailer's IDE just build all properties, methods and events from the
component's typelib. If the typelib is ok, then Xailer generates a complete
class, but if the typelib isn't complete, there is no way to do it. Although
sometimes there are some properties or methods which identifier conflicts
with a reserved id (that is, ambient properties or so). Then, those members
are not shown.

I'm affraid that there are many ActiveX components which are not properly
built.

Thanks Jose.
So could this means that calling the Refresh() method not necessarely calls
the MapObjectsLT2.Refresh() method?

Actually, I can't see that method in the component's typelib, so I belive
that the Xailer's one is called.
To be sure if this method belongs to the component, you may try this:
::oMap:Ocx:Invoke( "Refresh" )
if the method doesn't exists, then an error arise.

::oMap:Ocx:Invoke( "Refresh" ) doesn't crash th application, but it has no
effect. Actually the same happen with a Delphi application, so maybe it
something in the OCX that is not oke. With VB6 it works fine, but that's a
different story I guess.
How can I address properties that do not appear in the generate code in
Xailer?

Jose,
Can ::oLegend:SetMapSource(::oMap) be replaced with
::oLegend:Ocx:Invoke("SetMapSource", ::oMap)??
It doesn't crash, but it also does not have an effect.
BTW,
I got the scalebar working using ::oScaleBar:Ocx:Invoke( "Refresh" )
instead of ::oScaleBar:Refresh()
I am getting close with the MapViewer!
