[Gambas-user] Tooltip help using HTML.

Sat Jan 25 17:32:56 CET 2014

Hi Sam

It looks like you didn't close your second td of each row properly... I 
guess try it first with valid html...

Dim sHTML AS String

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

      gvEvents.Tooltip = sHTML

I would also be in the habit of wrapping the alignment and padding 
params in double-quotes, but perhaps that's getting too picky...and as 
you say, it doesn't seem to make much difference...

   Dim sHTML As String

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

Another thing to watch for is that your data might cause some odd 
effects if you have non-html-safe characters.

Kind regards,
Caveat
