Linux窗口程序设计,Qt4精彩实例分析,以循序渐进的方式介绍Qt4开发及其实例子,第一部分

#include <QtGui>

int main(int argc, char *argv[])

    QApplication app(argc, argv);

    tree.setSelectionMode(QAbstractItemView::MultiSelection);    
    list.setSelectionModel(tree.selectionModel());

    QObject::connect(&tree,SIGNAL(doubleClicked(QModelIndex)),&list,SLOT(setRootIndex(QModelIndex)));
    QObject::connect(&tree,SIGNAL(doubleClicked(QModelIndex)),&table,SLOT(setRootIndex(QModelIndex)));
