代码如下初始化时：--------------------------------------------------------------------------------------------------------------------------------- PlayerButton::PlayerButton(QWidget *parent) : QWidget(parent) { #if 1 m_pHLayout_7 = new QHBoxLayout; m_pPlayButton = new QPushButton( this ); //播放、暂停 //m_pPauseButton = new QPushButton( this ); //暂停 m_pStopButton = new QPushButton( this ); //停止 m_pBackwardButton = new QPushButton( this ); //后退 m_pForwardButton = new QPushButton( this ); //快进 m_pCloseFileButton = new QPushButton( this ); //关闭 #endif //设置按钮图片和去焦点虚框 this->addButtonImages(m_pPlayButton,":/images/image/pause.png",QSize(38,38)); this->addButtonImages(m_pStopButton,":/images/image/stop.png",QSize(38,38)); this->addButtonImages(m_pBackwardButton,":/images/image/backward.png",QSize(38,38)); this->addButtonImages(m_pForwardButton,":/images/image/step.png",QSize(38,38)); this->addButtonImages(m_pCloseFileButton,":/images/image/openfile.png",QSize(38,38)); this->addButtonImages(m_pNextButton,":/images/image/next.png",QSize(38,38)); m_Playing=true; m_pLabelTiming = new QLabel(STR_PLAYER_TIME,this); //播放时间 QFont font1; font1.setBold(true); //加粗 font1.setPixelSize(23); m_pLabelTiming->setFont(font1); //设置控件的位置和大小 int xpos = 8+20; m_pPlayButton->setGeometry(xpos,gScreenH-LowHigh-6-15,45,45); xpos += 51; m_pNextButton->setGeometry(xpos,gScreenH-LowHigh-6-15,45,45); xpos += 51; m_pStopButton->setGeometry(xpos,gScreenH-LowHigh-6-15,45,45); xpos += 51; m_pBackwardButton->setGeometry(xpos,gScreenH-LowHigh-6-15,45,45); xpos += 51; m_pForwardButton->setGeometry(xpos,gScreenH-LowHigh-6-15,45,45); xpos += 51; m_pCloseFileButton->setGeometry(xpos,gScreenH-LowHigh-6-15,45,45); #if 1 connect( m_pNextButton, &QPushButton::clicked, this,&PlayerButton::nextplayButton); connect( m_pPlayButton, &QPushButton::clicked, this,&PlayerButton::playButton); //connect( m_pPauseButton, &QPushButton::clicked, this,&Dialog::pauseButton ); //安装事件过滤器，用于响应按键的显示 m_pNextButton->installEventFilter(this); m_pPlayButton->installEventFilter(this); m_pStopButton->installEventFilter(this); m_pBackwardButton->installEventFilter(this); m_pForwardButton->installEventFilter(this); m_pCloseFileButton->installEventFilter(this); } 添加按钮图片代码 //添加按钮图片 void PlayerButton::addButtonImages(QPushButton *button,const QString path,QSize size) { QIcon icon( path ); button->setIcon(icon); button->setIconSize(size); //隐藏边界 button->setFlat(true); //设置按钮自定义没有焦点虚框风格 button->setStyle(new noFocusStyle()); qDebug()<<"PlayerButton::addButtonImages"<<endl; }//添加图片结束隐藏窗口 void PlayerButton::timehiden() { qDebug()<<"jindutiao hiden"<<endl; this->setHidden(true); this->update(); this->show(); this->setHidden(true); } 显示图片（在这里出问题，显示之后红框没了） void PlayerButton::setlayoutvisible() { this->setHidden(false); this->update(); this->show(); }
