    this->createTaskListTableContextMenu();
    this->createSmallWindow();

    this->taskThreadInfoTreeWidget->setMaximumWidth(120);

    this->mainSplitter = new QSplitter(Qt::Vertical,this);
    this->bottomSplitter = new QSplitter();
    QHBoxLayout *hBoxLayout = new QHBoxLayout(this->bottomSplitter);
    hBoxLayout->addWidget(this->taskThreadInfoTreeWidget);
    hBoxLayout->addWidget(this->taskThreadInfoDetailTableWidget);

    QVBoxLayout *vBoxLayout = new QVBoxLayout(this->mainSplitter);
    vBoxLayout->addWidget(this->taskListTable);
    vBoxLayout->addWidget(this->bottomSplitter);
