Qt4 Gossip: QSplitter

#include <QApplication>
#include <QSplitter>
#include <QTextEdit>

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);
   
    QSplitter *splitter = new QSplitter(Qt::Horizontal);
    splitter->setWindowTitle("QSplitter");
    splitter->addWidget(new QTextEdit);
    splitter->addWidget(new QTextEdit);
    splitter->addWidget(new QTextEdit);

    splitter->show();
    
    return app.exec();
}

直接來看執行畫面：



利用QSplitter的嵌套，可以組合出更複雜的畫面切割方式，例如：

#include <QApplication>
#include <QSplitter>
#include <QTextEdit>
#include <QListWidget>
#include <QLabel>

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);

    QListWidget *listWidget = new QListWidget;
    listWidget->insertItem(0, new QListWidgetItem(
                   QIcon("caterpillar_head.jpg"), "caterpillar"));
    listWidget->insertItem(1, new QListWidgetItem(
                   QIcon("momor_head.jpg"), "momor"));
    listWidget->insertItem(2, new QListWidgetItem(
                   QIcon("bush_head.jpg"), "bush"));
    listWidget->insertItem(3, new QListWidgetItem(
                   QIcon("bee_head.jpg"), "bee"));

    
    QSplitter *splitter1 = new QSplitter(Qt::Horizontal);
    splitter1->setWindowTitle("QSplitter");
    
    QSplitter *splitter2 = new QSplitter(Qt::Vertical);
    splitter1->addWidget(listWidget);
    splitter1->addWidget(splitter2);
    
    splitter2->addWidget(
       new QLabel("<h1><font color=blue>Hello!World!</font></h1>"));
    splitter2->addWidget(new QTextEdit);

    splitter1->show();
    
    return app.exec();
}

這個程式先將畫面進行水平切割，然後在右邊的切割中再進行垂直切割，所完成的畫面切割如下所示：
