示例1: cacheSectionMinSizes
void RDHeaderView::cacheSectionMinSizes()
{
m_sectionMinSizes.resize(count());
m_sectionMinSizesTotal = 0;
for(int i = 0; i < m_sectionMinSizes.count(); i++)
{
int sz = 0;
// see if we can fetch the column/row size hint from the item view
QAbstractItemView *view = qobject_cast<QAbstractItemView *>(parent());
if(view)
{
if(orientation() == Qt::Horizontal)
sz = view->sizeHintForColumn(i);
else
sz = view->sizeHintForRow(i);
}
// also include the size for the header as another minimum
if(orientation() == Qt::Horizontal)
sz = qMax(sz, sectionSizeFromContents(i).width());
else
sz = qMax(sz, sectionSizeFromContents(i).height());
// finally respect the minimum section size specified
sz = qMax(sz, minimumSectionSize());
// update the minimum size for this section and count the total which we'll need
m_sectionMinSizes[i] = sz;
m_sectionMinSizesTotal += m_sectionMinSizes[i];
}

void UIHostNetworkManagerWidget::sltAdjustTreeWidget()
{
/* Get the tree-widget abstract interface: */

/* Propose suitable width hints for non-important columns: */
