Qt实现360安全卫士主界面（中央窗体）

中央窗口可以分为左右两部分，左半边由QWidget实现，包含三个QLabel,一个QPushButton,QLabel主要用来显示图片，文本信息，还有一个按钮负责“立即体验”。

右半边由QSplitter实现分割窗口，每个QWidget又包含不同的组件。

整体部分由QSplitter将左半边的QWidget与右半边的QSplitter分割，分割线均不可拖动。

小技巧：

当一次需要创建多个按钮时，我们可以通过容器QStringList将图片路径写入

eg:

QStringList string_list;string_list << ":/contentWidget/recovery" << ":/contentWidget/moblie" << ":/contentWidget/game_box" << ":/contentWidget/desktop"<< ":/contentWidget/net_repair" << ":/contentWidget/auto_run" << ":/contentWidget/net_speed" << ":/contentWidget/net_pretext"<< ":/contentWidget/first_add";

button_list.at(0)->setText(tr("recovery"));button_list.at(1)->setText(tr("mobile"));button_list.at(2)->setText(tr("game box"));button_list.at(3)->setText(tr("desktop"));button_list.at(4)->setText(tr("net repair"));button_list.at(5)->setText(tr("auto run"));button_list.at(6)->setText(tr("net speed"));button_list.at(7)->setText(tr("net pretext"));button_list.at(8)->setText(tr("first add"));
