函数使用_24.QTableView函数使用,右击菜单实现

QTableView view(this);
QStandardItemModel model(this);
model.setHorizontalHeaderItem(0,new QStandardItem("Name"));
model.setHorizontalHeaderItem(1,new QStandardItem("Sex"));
model.setHorizontalHeaderItem(2,new QStandardItem("Age"));
model.horizontalHeaderItem(0)->setFont(QFont("Helvetica",20,50)); //设置标题字体
model.setVerticalHeaderItem(0,new QStandardItem("No.1"));
model.setVerticalHeaderItem(1,new QStandardItem("No.2"));
model.setVerticalHeaderItem(2,new QStandardItem("No.3"));
QPixmap pix(":user.png");
pix =pix.scaled(24,24,Qt::KeepAspectRatio);
QStandardItem *itemA=new QStandardItem();
itemA->setData(pix,Qt::DecorationRole); //设置条目图标
itemA->setData("A",Qt::DisplayRole);
itemA->setData("A:tooltip",Qt::ToolTipRole);
itemA->setData(QFont("宋体",12,QFont::Bold,true),Qt::FontRole); //设置条目字体
itemA->setData(Qt::AlignCenter,Qt::TextAlignmentRole); //设置条目中心对齐
QLinearGradient linearGradient(0,0,100,20);
linearGradient.setColorAt(0.2, Qt::white);
linearGradient.setColorAt(0.6, Qt::green);
linearGradient.setColorAt(1.0, Qt::black);
itemA->setData(QBrush(linearGradient),Qt::BackgroundRole); //设置条目背景色(为渐变色)
model.setItem(0,0,itemA);
model.setItem(0,1,new QStandardItem("B"));
model.setItem(1,0,new QStandardItem("C"));
model.item(0,1)->setTextAlignment(Qt::AlignCenter); //设置条目居中对齐
model.sort(0,Qt::DescendingOrder);

 view.sortByColumn(0);

view.setSortingEnabled(true);

 view.setAutoScroll

view->horizontalHeader()->setHighlightSections(false);

view.horizontalHeader()->setResizeMode(QHeaderView::Fixed);
view.verticalHeader()->setResizeMode(QHeaderView::Fixed);

 view.setSelectionMode(QAbstractItemView::NoSelection);

 view.verticalHeader()->hide();

view.setSelectionMode(QAbstractItemView::SingleSelection);

//设置选择模式,表示只能选中单个

 view.setSelectionBehavior(QAbstractItemView::SelectRows);

                      //设置选择行为,表示只能选择一行(也可以设置为列,或者单个Item项目)

view.setEditTriggers(QAbstractItemView::NoEditTriggers);
view.horizontalHeader()->setVisible(false);
view.verticalHeader()->setVisible(false);
view.setShowGrid(false);
view.setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
view.setColumnWidth(0,50); //设置column0(第1列)的宽度为50
view.setRowHeight(0,30); //设置row0(第1行)的高度为30
view.resizeRowsToContents(); //更据当前内容自动调整行距
view.resizeColumnsToContents(); //更据当前内容自动调整列距

 view.setFocusPolicy(Qt::NoFocus);
