總結一些常用表的用法
QListWidget的用法
void TableWidget::initListWidget()
{
//插入方法1
ui->listWidget->addItem("Program Files");
//插入方法2
QListWidgetItem* pInsertItem = new QListWidgetItem();
pInsertItem->setText("Program Files(x64)");
ui->listWidget->insertItem(1,pInsertItem);
ui->listWidget->insertItem(2,"Program Files(x64)副本");
ui->listWidget->insertItems(3,QStringList()<<
QStringLiteral("Program Files(x64)副本1")<<
QStringLiteral("Program Files(x64)副本2"));
//插入方法3
ui->listWidget->addItem("ProgramData");
QListWidgetItem* pAdditem = new QListWidgetItem();
pAdditem->setText("ProgramData副本");
ui->listWidget->addItem(pAdditem);
ui->listWidget->addItems(QStringList()
<< QStringLiteral("ProgramData副本1")
<< QStringLiteral("ProgramData副本2")
<< QStringLiteral("ProgramData副本3"));
//設置圖標
pInsertItem->setIcon(QIcon(":/image/folder.ico"));
pAdditem->setIcon(QIcon(":/image/folder.ico"));
//設置勾選狀態
pInsertItem->setCheckState(Qt::Checked);
pAdditem->setCheckState(Qt::Unchecked);

QListView的用法

pItem->setText("Program Files(x64)");
pItem->setIcon(QIcon(":/image/folder.ico"));
pItem->setCheckState(Qt::Checked);
