示例1: render

{
MultiColumnList* w = (MultiColumnList*)d_window;
const ListHeader* header = w->getListHeader();
const Scrollbar* vertScrollbar = w->getVertScrollbar();
const Scrollbar* horzScrollbar = w->getHorzScrollbar();
// render general stuff before we handle the items
cacheListboxBaseImagery();
//
// Render list items
//
Vector3f itemPos;
Sizef itemSize;
Rectf itemClipper, itemRect;
// calculate position of area we have to render into
Rectf itemsArea(getListRenderArea());
// set up initial positional details for items
itemPos.d_y = itemsArea.top() - vertScrollbar->getScrollPosition();
itemPos.d_z = 0.0f;
const float alpha = w->getEffectiveAlpha();
// loop through the items
for (uint i = 0; i < w->getRowCount(); ++i)
{
// set initial x position for this row.
itemPos.d_x = itemsArea.left() - horzScrollbar->getScrollPosition();
// calculate height for this row.
itemSize.d_height = w->getHighestRowItemHeight(i);
// loop through the columns in this row
