[Gambas-user] Tooltip help using HTML.

Hi all,

   I'm having a problem with the tooltips.  It works fine with regular 
text but when I use HTML for a multi-line tooltip the results are not 
predictable.  Most of the time an extra blank line shows up at the 
bottom. Seems like it might be wrapping if the last line is shorter (yes 
shorter).

   A code example looks like :

Dim sHTML AS String

     sHTML &= "<html>"
     sHTML &= "<table cellpadding=1>"
     sHTML &= "<tr><td align=right>Note on</td><td align=left>G#/Ab</tr>
     sHTML &= "<tr><td align=right>Row</td><td align=left>44</tr>
     sHTML &= "<tr><td align=right>Velocity</td><td align=left>96</tr>
     sHTML &= "</table>"
     sHTML &= "</html>"

     gvEvents.Tooltip = sHTML

   It does not seem to matter if the "<html>" tag is included or not or 
if the attribute values are enclosed
in single or double quotes.  The table cells can have different colors 
or font sizes and works fine.  Just a
strange extra line at the bottom (not always).  Any idea?  I've tried 
numerous simple HTML snippets
that work fine and wonder if it is just the fact of the <table> inside.

   I've been developing a MIDI app using the ALSA API which works well 
but I'm surprised there is
not a wrapper already out there for Gambas, anyone already written one?

   The opaque structures and macros for hiding the actual implementation 
are a good design for C but not so nice for Gambas. I gave up on the 
timing callback thinking the callback cannot occur properly since they 
are on different threads. I have a separate player and a GUI that 
communicate via pipes, works good.

  Thanks for Gambas!  I come home from a day of Java abstract 
frameworks, inversion of control, more
and more bloat and just write stuff that is fun and actually works.
