ColumnList clipping problem [message #46429]

I'm trying to draw an outline around the active item in a ColumnList. I'm drawing outlines and not using background color because the ColumnList is meant to never be focused. That's why I added a LineEdit in the sample, to take the focus away.

When the cursor is on the first item, it is drawn correctly.

Any other line, the last line of pixels is clipped from the item.

PS: How do you disable the drag and drop column resizing?

PS2: Years ago, when I used U++, there was some method of getting the system colors, for highlights, shadows and stuff. I can't find it anymore.

Found them by accident: they start with S.

Nevermind.

The problem was that I was passing in right and bottom, not width and height.

One more question: does the style field in the display have support for telling me if the item is drawn in that popup that shows up when the calculated size is greater than the element?
