前面已经说了很多用法了，下面主要说说绑定键盘，设置Icon图片。

绑定键盘快捷键

实现四个按钮，可以使用wsad来控制另一个按钮的上下左右的移动。

#include "widget.h"
#include "ui_widget.h"

Widget::Widget(QWidget *parent)
    : QWidget(parent)
    , ui(new Ui::Widget)
{
    ui->setupUi(this);

    QIcon icon(":/koumo.png");
    this->setWindowIcon(icon);

    ui->pushButton_target->setIcon(icon);
    ui->pushButton_target->setIconSize(QSize(120, 120));

    ui->pushButton_up->setShortcut(Qt::CTRL + Qt::Key_W);
    ui->pushButton_down->setShortcut(Qt::Key_S);
    ui->pushButton_left->setShortcut(Qt::Key_A);
    ui->pushButton_right->setShortcut(Qt::Key_D);
}

Widget::~Widget()
{
    delete ui;
}

void Widget::on_pushButton_up_clicked()
{
    QRect rect =  ui->pushButton_target->geometry();
    ui->pushButton_target->setGeometry(rect.x(), rect.y() - 5, rect.width(), rect.height());
}
void Widget::on_pushButton_down_clicked()
{
    QRect rect =  ui->pushButton_target->geometry();
    ui->pushButton_target->setGeometry(rect.x(), rect.y() + 5, rect.width(), rect.height());
}
void Widget::on_pushButton_left_clicked()
{
    QRect rect =  ui->pushButton_target->geometry();
    ui->pushButton_target->setGeometry(rect.x() - 5, rect.y(), rect.width(), rect.height());
}
void Widget::on_pushButton_right_clicked()
{
    QRect rect =  ui->pushButton_target->geometry();
    ui->pushButton_target->setGeometry(rect.x() + 5, rect.y(), rect.width(), rect.height());
}
