Hi Paul,
here is a simple example that should cover both of your recent questions.
It sets a checkbox as a renderer/editor and in keeps the selection
background.
You must set the correct selection background in you renderer code.
To do this you use the "isSelected" argument of the renderer method. It
indicates
whether the currently rendered cell is selected or not.
Hope this helps.
Greetings,
Daniel

Subject: [ULC-developer] ULCTable - Cell renderers
Hello
I am using the ULCTables quite extensively within our application. I need to
format the cells according to database types (chars, numbers, dates,
checkboxes etc). I do this by setting the cell renderes and it works well.
The only problem is, as soon as I set the cell renderers I loose the row
selection! The user can still select rows but there is no record indicator
(coloured row) when selected. This is also the case for column selection. Do
you have any ideas what I should do to get the selection colour back?
Paul Harrison
