Hi,
At design time the jListView shows with separating lines between
items, but at runtime the items come indistinct. The event
OnDrawItemBackground may have helped to set-up an alternated
background colour but it only colours the text background and not the
whole item...
To circumvent that problem I thought of drawing lines (or alternated
background) using a JCanvas with onAfterDispatchDraw event, but I've
no idea how to process !
Could someone inspire me ?
Thanks.

Hi, zebu1er!

Can you put here some draft picture showing what you want to achieve?

Here are the attachments :
- natural : How it looks at execution time
- event-colored : How it looked using the event OnDrawItemBackground
- line-separated : How it may look according the component Lazarus
toolbar icon
- alternate-colored : How I hoped the OnDrawItemBackground to behave

You can also use "lvItems.SetDrawAlphaBackground(0);" to define the
color of the transparency and adjust it if desired or set it to 0
which will be the same as the desired color but will lose the
functionality of the OnClick and OnLongClick visual feedback.

Nice feature  Next, maybe about adding a text item with a pattern.
Like this one maybe?
