一、所需工具软件
1. VS, Qt
2. C++
二、使用步骤
1.引入库
#include "MainWindow.h"
#include<iostream>
#include<qDebug>
#include<QFile>
#include <QBitmap>
#include <QPainter>
#include<QImage>
#include<QPixmap>
#include <QGraphicsScene>
#include <QGraphicsView>
#include <QPointF>
#include <QLineF>
2. 代码实现
代码如下:
.h*************************************
#pragma once
#include <QtWidgets/QMainWindow>
#include "ui_MainWindow.h"
#include <qDebug>
class MainWindow : public QMainWindow
{
Q_OBJECT
public:

protected:
private:
Ui::MainWindowClass ui;
private slots:
void OnSearch();
void mapBackGround();

void paintEvent(QPaintEvent* event);
void initStyleSheetMapButton();
void initStyleSheetButton();
void initStyleSheetLabel();
};
