QT stackwidget控件支持上下，左右手势滑动，触摸屏
一.使用示例代码
包含fingerswipegesture和slidingstackedwidget两个类，使用如下：
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QLabel>MainWindow::MainWindow(QWidget *parent): QMainWindow(parent), ui(new Ui::MainWindow)
{ui->setupUi(this);setAttribute(Qt::WA_AcceptTouchEvents);connect(ui->stackedWidget, SIGNAL(fingerGesture(SlidingStackedWidget::SlideDirection)),this, SLOT(onFingerGesture(SlidingStackedWidget::SlideDirection)));
}void MainWindow::onFingerGesture(SlidingStackedWidget::SlideDirection direction)
{if (direction == SlidingStackedWidget::LeftToRight)ui->stackedWidget->slideInIdx(1);else if (direction == SlidingStackedWidget::RightToLeft)ui->stackedWidget->slideInIdx(0);
}MainWindow::~MainWindow()
{delete ui;
