QCustomPlot plot clicked problem
I want to receive an information that plot was clicked using QCustomPlot. I tried this:
connect(ui->customPlot, SIGNAL(plottableClicked(QCPAbstractPlottable*,int,QMouseEvent*)), this, SLOT(plotClicked(QCPAbstractPlottable*,int,QMouseEvent*)));
but it did not work. The problem is that when I click on a plot, the slot is not executing.
Assuming the signal and slot is all working, it is probably a typing error in your connect statement. You can check the return value of connect. It will tell, if there is a problem with the connection. Also you should see an error message on the terminal output (or the application output window, when started in creator).
You could use also functor-based connect. This would show you already during compile time typing issues.
Furthermore, QCustumPlot is a library based on Qt and you need to contact the publisher of the library for details there.
You should try qDebug() "con1:"<< connect(ui->customPlot, xxx)
and see if it says true.
The syntax seems valid
Also check that whatever class, the "this" is , has Q_OBJECT macro. in the .h file.
connect returns true. This class has Q_OBJECT macro in the .h file.
Ok, maybe it just dont emit the signal.
You could try
and see if their
connect(ui->customPlot, SIGNAL(plottableClick(QCPAbstractPlottable*,int,QMouseEvent*)), this, SLOT(graphClicked(QCPAbstractPlottable*,int)));
No, it doesn't.
Well maybe there is something with our installation of it. Normally the samples works.
Have you tried their forum ? ( if any)
I found another way: I used signal mousePressed and ckeck if the plot is select by selected() function.
