1、CcTestVideoPlayer类 模拟播放器类继承QGraphicScene
1.1 CcTestVideoPlayer.h
#pragma once#include QGraphicsView
#include QGraphicsScene
#include QVariant
#include QSharedPointerclass CcTestVideoPlayer : public QGraphicsView
{Q_OBJECTpublic:CcTestVideoPlayer(QWidget *parent nullptr, QGraphicsScene* scene nullptr);~CcTestVideoPlayer(void);protected:void drawBackground(QPainter *painter, const QRectF rect)override;};1.2 CcTestVideoPlayer.cpp
#include CcTestVideoPlayer.h#include QLabel
#include QStyle
#include QPainter
#include QPaintEngine
#include QGraphicsProxyWidget
#include QMenu
#include QApplication
#include QTimerCcTestVideoPlayer::CcTestVideoPlayer(QWidget *parent, QGraphicsScene* scene): QGraphicsView(parent)
{if (scene){scene-setParent(this);}setScene(scene ? scene : new QGraphicsScene(this));auto widget new QWidget;widget-setStyleSheet(background:white;);widget-setFixedSize(QSize(300,420));scene-addWidget(widget)-setZValue(101);
}CcTestVideoPlayer::~CcTestVideoPlayer()
{}void CcTestVideoPlayer::drawBackground(QPainter *painter, const QRectF rect)
{QGraphicsView::drawBackground(painter, this-rect());painter-fillRect(geometry(), QBrush(#0c0b0f));
}2、CcTestVideoSurface 继承QGraphicsScene
2.1 CcTestVideoSurface.h
#pragma once#include QGraphicsScene
#include QObject
#include QLabelclass CcTestVideoSurface : public QGraphicsScene
{Q_OBJECTpublic:CcTestVideoSurface(QObject *parent Q_NULLPTR);virtual ~CcTestVideoSurface(void);void showTips();private:QLabel* m_tipsInfoLabel nullptr;QWidget* m_containter nullptr;
};2.2 CcTestVideoSurface.cpp
#include CcTestVideoSurface.h#include QGraphicsProxyWidget
#include QHBoxLayout
#include QVBoxLayoutCcTestVideoSurface::CcTestVideoSurface(QObject *parent): QGraphicsScene(parent)
{m_containter new QWidget();m_containter-setObjectName(QStringLiteral(tip_container));m_containter-setStyleSheet(#tip_container { background-color: transparent;});m_tipsInfoLabel new QLabel(nullptr);m_tipsInfoLabel-setFixedSize(120, 38);m_tipsInfoLabel-setObjectName(QStringLiteral(tip));m_tipsInfoLabel-setStyleSheet(#tip { background-color: rgba(10,132,254,0.6); border: none; border-radius: 15px; font-size:12px; color:#edf1fa;});m_tipsInfoLabel-setAlignment(Qt::AlignCenter);m_tipsInfoLabel-setText(测试悬浮在view);auto tipLayout new QHBoxLayout;tipLayout-setSpacing(0);tipLayout-setMargin(0);tipLayout-addStretch();tipLayout-addWidget(m_tipsInfoLabel);tipLayout-addStretch();auto layout new QVBoxLayout(m_containter);layout-setSpacing(0);layout-setMargin(0);layout-addStretch();layout-addLayout(tipLayout);layout-addSpacing(4);addWidget(m_containter)-setZValue(102);
}CcTestVideoSurface::~CcTestVideoSurface(void)
{}void CcTestVideoSurface::showTips()
{if (m_containter){m_containter-setVisible(true);}
}3、main.cpp
#include QApplication
#include QWidget
#include QDebug//cc-engine里面生成的动态库
#include CcDataManage.h
#include CcJsonTool.h#include cc-test/CcTestVideoPlayer.h
#include cc-test/CcTestVideoSurface.h//测试graphic viewvoid test_qJson()
{//TODO: qt json 简单使用测试auto cmd 1001;auto type 1;auto content 05:00;QVariantMap contentMap;contentMap[cmd] QString::number(cmd);QVariantMap dataMap;dataMap[type] type;dataMap[content] content;contentMap[data] dataMap;CcJsonTool jsonTool;auto str jsonTool.toJsonFromVariantMap(contentMap);qDebug() jsonStr: str;//jsonStrauto JsonStr {\cmd\:\1001\,\data\:{\content\:\05:00\,\type\:1}};if (jsonTool.parseJsonFromString(JsonStr)){qDebug() parse json str success;}else{qDebug() parse json str failed;}
}void test_dll_manage()
{CcDataManage data_manage;qDebug() Get Data From cc-engine dynamic library: data_manage.GetCurrentJsonData();
}int main(int argc, char *argv[])
{QApplication app(argc, argv);//Qt json 简单测试test_qJson();//一个项目多个子项目并且子项目是动态库调用测试test_dll_manage();//QGraphicView和QGraphicScene简单测试auto videoSurface new CcTestVideoSurface();videoSurface-showTips();auto graphicView new CcTestVideoPlayer(nullptr, new CcTestVideoSurface());graphicView-setFixedSize(QSize(520, 420));graphicView-show();// QWidget window;// window.resize(650, 350);// window.setWindowTitle(简单的cmake构建的Qt窗口程序);// window.show();return app.exec();
