Slot Declaration rare problem to resolve[SOLVED]
Hi.
I am finishing to code custom MainWindow class:
mainwindow.h file:
- #ifndef MAINWINDOW_H
- #define MAINWINDOW_H
- #include <QMainWindow>
- #include <QFileDialog>
- #include "qwt_plot_canvas.h"
- #include "lib/wfdb.h"
- #include "lib/ecgmap.h"
- #include "curvedata.h"
- #include "qwt_plot_grid.h"
- //temporary
- #include <QDebug>
- namespace Ui {
- class MainWindow;
- }
- {
- Q_OBJECT
- public:
- ~MainWindow();
- private:
- void init_plot();
- void process();
- public slots:
- void LoadData();
- private:
- Ui::MainWindow *ui;
- CurveData *cvData_in;
- CurveData *cvData_out;
- QwtPlotCurve *qwtpltcrv_in;
- QwtPlotCurve *qwtpltcrv_out;
- int lp[LP_SIZE];
- char *db_name;
- };
- #endif // MAINWINDOW_H
the slot LoadData is definde in mainwindow.cpp file as:
void MainWindow::LoadData()
{
…
}
as well as another functions:
but when compiling as usual using
Qt 4.8.0 for Desktop – MinGW ( Qt SDK ), Mingw as GCC for windows targets
Compile output contains next notification about slot declaration:
In file included from main.cpp:2:
mainwindow.h:26: error: expected ‘:’ before ‘slots’
mainwindow.h:27: error: expected primary-expression before ‘void’
mainwindow.h:27: error: ISO C++ forbids declaration of ‘slots’ with no type
mainwindow.h:27: error: expected ‘;’ before ‘void’
Would somebody help me / point out why such problem?
How to resolve and to get succesfull compilation?
Thnaks in advance,
Paul

What happens when you don’t use the public slots notation, but Q_SLOTS?
does qmake run successfully?
—Thank you.The code after replacing public slots notation to Q_SLOTS compiled and run successfully.That is because of includes of QWT in the project I guess with high likelihood and having a reason.
Solved.
