Hi,
I'm trying to embed the Microsoft MapPoint 2004 ActiveX control into a
SWT application.
I modified the sample application that comes with the introductory
article by IBM about SWT support of ActiveX/OLE controls in order to use
tha MapPoint 2004 control in place of the PDF reader.
I was able to instanciate the control, have it load a map and display
itself in the application frame.
However, unlike the other controls I've tested, it looks like the
control fails to get the focus, and, as a result, it does not receive
any mouse events.
Just to add more information, I've also tested this ActiveX control by
writing a MFC and a VB application, both of which work fine.
In order to make things clearer , I've written a simpler application
that basically loads and displays the control, and prints the focus
status to standard output (please see attached file, SWTSample.java).
As you can see the control site object never gets the focus, while the
OLE frame does. The source file also contains a few lines of
commented-out code that use the Internet Explorer control, which you can
uncomment to check the overall application and see the expected
behaviour (in this case both the frame and the site object get the focus).
I'm using Eclipse 3.1 RC2, Microsoft MapPoint 2004 European edition on
MS Windows 2000 and Sun's JDK 1.5.0_02 for Windows.
I have checked the forums and bugzilla, and looked for a hint on the Web
but I could not find any solution.
Is it a common problem, or a bug? How can I solve it? Is the test
application OK or should I change/add anything to make it work?
Thank you in advance.
Best regards,
Marcello Atzeni
