I have seen many answers for the same Question, I have already gone through them but none them solved my problem, I am getting the error
QWidget::paintEngine: Should no longer be called QPainter::begin: Paint device returned engine == 0, type: 1 QPainter::end: Painter not active, aborted
I need to know, What is type : 1, and why this error showing,
My code is
iconwidget.h
class IconWigdet : public QAbstractButton{Q_OBJECTQRect *iconarea;QPainter p;QPixmap *icon; public:explicit IconWigdet(QRect *rectangle,QPixmap *tempicon);void paintEvent(QPaintEvent *); };iconwidget.cpp
IconWigdet::IconWigdet(QRect *rectangle,QPixmap *tempicon){iconarea = new QRect();*iconarea = *rectangle ;icon = new QPixmap(*tempicon);this->setGeometry(0,0,iconarea->width(),iconarea->height()+20);}void IconWigdet::paintEvent(QPaintEvent *){qDebug() << " PaintEvent ";p.begin(this);p.drawText(iconarea->x()+ 10,iconarea->height()+10, "name");p.drawPixmap ( *iconarea,*icon );p.end();}groupwidget.h
class GroupWidget: public QWidget{Q_OBJECTQGridLayout *groupLayout = new QGridLayout ;QRect *rect = new QRect( 0, 0, 100, 100);QPixmap *pimap = new QPixmap("../widgeticon/icons/ball.png");IconWigdet *icon = new IconWigdet(rect,pimap);public:GroupWidget();};groupwidget.cpp
GroupWidget::GroupWidget(){ groupLayout->addWidget(icon, 0, 1, 1, 1, 0);this->setLayout(groupLayout);icon->show();QPaintEvent *e;icon->paintEvent(e);}main.cpp
int main(int argc, char *argv[]){QApplication a(argc, argv);GroupWidget *Gw = new GroupWidget;Gw->show();return a.exec();}and the iconwidget class will work perfectly if the main function changed to
int main(int argc, char *argv[]){QApplication a(argc, argv);; QRect *rect = new QRect( 0, 0, 100, 100);QPixmap *pimap = new QPixmap("../widgeticon/icons/ball.png");IconWigdet *Iw = new IconWigdet(rect,pimap);Iw->show();return a.exec();}that means, If we use iconwidget class object in main function it is working, but it is not working when we do the same in groupwidget class,
Thanks in advance
