Slot doesn't seem to work

[waynew]

A pushbutton, pbSave, in the StnInfoDialog form needs to call the slot insertInfo in the stninfodialog.cpp passing the value of the form field 'call'
Here is the code:

#include "stninfodialog.h"
#include "ui_stninfodialog.h"
#include "makestndb.h"
#include "insertstninfo.h"
#include <QDebug>
 
StnInfoDialog::StnInfoDialog(QWidget *parent) :
    QDialog(parent),
    m_ui(new Ui::StnInfoDialog)
{
    m_ui->setupUi(this);
 
    connect(m_ui->pbSave, SIGNAL(clicked(bool)),
     this, SLOT(insertInfo(m_ui->call->text())));
   }
}
 
void StnInfoDialog::insertInfo(QString mycall)
{
       InsertStnInfo insert;
       insert.insertStnInfo(mycall); 
}

#include "stninfodialog.h"
#include "ui_stninfodialog.h"
#include "makestndb.h"
#include "insertstninfo.h"
#include <QDebug>

StnInfoDialog::StnInfoDialog(QWidget *parent) :
    QDialog(parent),
    m_ui(new Ui::StnInfoDialog)
{
    m_ui->setupUi(this);

    connect(m_ui->pbSave, SIGNAL(clicked(bool)),
     this, SLOT(insertInfo(m_ui->call->text())));
   }
}

void StnInfoDialog::insertInfo(QString mycall)
{
       InsertStnInfo insert;
       insert.insertStnInfo(mycall); 
}

To copy to clipboard, switch view to plain text mode 

Problem is, the slot never gets called when pbSave is clicked.
Can someone please show me what I am doing wrong?

connect(m_ui->pbSave, 
    SIGNAL(clicked(bool)), this,
    SLOT(insertInfo(m_ui->call->text())));

connect(m_ui->pbSave, 
    SIGNAL(clicked(bool)), this,
    SLOT(insertInfo(m_ui->call->text())));

To copy to clipboard, switch view to plain text mode 

Try this:

connect( m_ui->pbSave, 
    SIGNAL( clicked() ), this,
    SLOT( insertInfo( ) ) );

connect( m_ui->pbSave, 
    SIGNAL( clicked() ), this,
    SLOT( insertInfo( ) ) );

To copy to clipboard, switch view to plain text mode 

You can't submit a parameter with insertInfo(). You could create your own signal, but may be a private variable will do the job.

Tnx gboelter - got it working ok now by eliminating the parameter and getting the form field value while in insertinfo, then passing it to the insert database method.

From Qt Doc:

Note that the signal and slots parameters must not contain any variable names, only the type.

The signature of a signal must match the signature of the receiving slot. (In fact a slot may have a shorter signature than the signal it receives because it can ignore extra arguments.

So:

use only type: Qstring, int and not QString dummy or int Bignumber, only QString or int.
If u can use the same number of parameters too.


Hope this help
