alternatingRowColor

[wirasto]

I tried make a custom style for my treeview with QProxyStyle. But I'm lost alternatingRowColor function. How to keep it ? Or make a new alternatingRowColor ?
Well, I tried set the alternatingrowcolor with stylesheet too. But still not working.. :cryi

What class is QProxyStyle ??
You do alternate colors in paint event of items. You can check -

if(row % 2 == 0)
   // use color1
else
  // use color2

if(row % 2 == 0)
   // use color1
else
  // use color2

I tried like that. But I have 3 column, and PE_PanelItemViewRow PE_PanelItemViewItem will set every cell, not every row.

QProxyStyle, check in qtdoc

Looking in the source directory, and selecting a style at random, one finds:

if (newStyle && view && (vopt = qstyleoption_cast<const QStyleOptionViewItemV4 *>(option))) {
                bool selected = vopt->state & QStyle::State_Selected;
                bool hover = vopt->state & QStyle::State_MouseOver;
                bool active = vopt->state & QStyle::State_Active;
 
                if (vopt->features & QStyleOptionViewItemV2::Alternate)
                    painter->fillRect(vopt->rect, vopt->palette.alternateBase());

if (newStyle && view && (vopt = qstyleoption_cast<const QStyleOptionViewItemV4 *>(option))) {
                bool selected = vopt->state & QStyle::State_Selected;
                bool hover = vopt->state & QStyle::State_MouseOver;
                bool active = vopt->state & QStyle::State_Active;

                if (vopt->features & QStyleOptionViewItemV2::Alternate)
                    painter->fillRect(vopt->rect, vopt->palette.alternateBase());

I can't convert QStyleOptionViewItem to QStyleOptionViewItemV4 ?

vopt = qstyleoption_cast<const QStyleOptionViewItemV4 *>(option);

vopt = qstyleoption_cast<const QStyleOptionViewItemV4 *>(option);

my option variable is QStyleOptionViewItem. Btw, I tried in paint function on my custom delegate.
