Ok, so then in my case, I'd just inherit from QStyledItemDelegate and add a
function that allows me to pass in my QMap<myItem*, QColor> so that I can
adjust your calls of setColor() in paint() on the fly based on modelIndex.
Do you happen to have any pointers for customizing the drag and drop indicator?
In my case, the user can only reorder rows, so I'd like the drop indicator to
just be a thick line drawn in between rows, not a rectangle around an item/row.
I was playing around with a custom QProxyStyle set on the view class,
overloading drawPrimitive(QStyle::PrimitiveElement element, const QStyleOption
*option, QPainter *painter, const QWidget *widget) when the element is a
QStyle::PE_IndicatorItemViewItemDrop. I was able to have the indicator be just
a line, but I was struggling a little to determine when the indicator needs to
switch from being drawn above a row to below the row based on mouse pointer
position. I didn't spend a lot of time on it though, so I may just need to go
back and play with it some more.
Thanks!
