Qt中splitter的使用

QSplitter *splitter1=new QSplitter(Qt::Horizontal);

QTreeWidget *treeWidget=new QTreeWidget;

treeWidget->setColumnCount(1);

QString Header="Folders";

treeWidget->setHeaderLabel(Header);

QStringList first;

first<<"Mail";

QTreeWidgetItem *firstRoot=new QTreeWidgetItem(treeWidget,first);

QStringList second1;

second1<<"Inbox";

QTreeWidgetItem *secondRoot1=new QTreeWidgetItem(firstRoot,second1);

QStringList second2;

second2<<"Outbox";

QTreeWidgetItem *secondRoot2=new QTreeWidgetItem(firstRoot,second2);

QStringList second3;

second3<<"Sent";

QTreeWidgetItem *secondRoot3=new QTreeWidgetItem(firstRoot,second3);

QStringList second4;

second4<<"Trash";

QTreeWidgetItem *secondRoot4=new QTreeWidgetItem(firstRoot,second4);

QTreeWidget *treeWidget2=new QTreeWidget;

QTextEdit *edit1=new QTextEdit;

edit1->setText("The First");

QTextEdit *edit2=new QTextEdit;

edit2->setText("The Second");

QSplitter *splitter=new QSplitter(Qt::Vertical);

splitter->addWidget(treeWidget2);

splitter->addWidget(edit1);

splitter->addWidget(edit2);

splitter1->addWidget(treeWidget);

splitter1->addWidget(splitter);

splitter1->show();
