Description
Hi,
I have a simple Slot,
void sendImage(cv::Mat &imgMat, QImage &imgQImage);
Project compiles on both Mingw and Visual Studio but when i try to build for Android, i get "error: no matching function for call to imageReader::sendImage(cv::Mat&, QImage)" error. (Signal emitting works as expected in Visual Studio/Mingw and no warning in stdout) I tried removing cv::Mat but nothing changed.
Project compiles on both Mingw and Visual Studio but when i try to build for Android, i get "error: no matching function for call to imageReader::sendImage(cv::Mat&, QImage)" error.
I tested my pro file on different project, try clean/run qmake/clean/rebuild, remove cv::Mat from signal but nothing worked.
Here is my Slot
#ifndef READERMANAGERQMLINTERFACE_H #define READERMANAGERQMLINTERFACE_H #include <QObject> #include <QDebug> #include "readermanager.h" class ReaderManagerQMLInterface : public QObject { Q_OBJECT public: explicit ReaderManagerQMLInterface(QObject *parent = 0); ~ReaderManagerQMLInterface(); readerManager rManager; private: signals: void reqIm(); public slots: void sendImage(QImage &imgQImage); //cv::mat removed }; #endif // READERMANAGERQMLINTERFACE_H
and signal;
#ifndef IMAGEREADER_H #define IMAGEREADER_H #include <QObject> #include <QImage> #include <QDebug> #include <QThread> #include <QDir> #include <QFile> class imageReader : public QObject { Q_OBJECT public: explicit imageReader(QObject *parent = 0); ~imageReader(); imgHelpers imHelpers; signals: void sendImage(QImage &imgQImage);//cv::mat removed public slots: void requestImage(); void setFrame(int frameID); void loadImage(QString fileName); }
I tried connecting these two with old and new syntax;
QObject::connect(this->rManager.imreader, SIGNAL(sendImage(QImage&)), this, SLOT(sendImage(QImage&)) ); connect(this->rManager.imreader, &imageReader::sendImage, this, &MainWindow::sendImage );
Is it a moc related bug or am i missing something?
