Owner draw issues with ListIconGadgets
Posted: Sat Nov 14, 2009 1:37 pm
Hm,
I've some problems implementing a callback to show bars in the last four columns of a listicongadget -- additionally ther should be a color marker in one of the cells. But this (red) background color will be seen also within the last 4 columns
and there's also another issue, because not all of the rows will show the bars 
Here's the code - you may have a look at it:
