qcheckbox SLOT doesnot get called on clicked

Pradeep Kumar

HI,

Have u provided macro Q_OBJECT.?
And the function to be called, SLOT , is it under public /private SLOT() section, ?

And as @dream_captain said , can u provide the code.

Thanks,

Sumit

This function was working previously.
I tried both the ways: Signal and slots and also through ui (right click and go to slot).
The below code is not as it is in my workspace. i had added the important info regarding Qcheckbox

code::
some.hpp

#include <QWidget>
#include "common/abs_includes.hpp"
#include "core/abs_va_ucf_handler.hpp"
#include <QtWidgets/QDialog>
#include "qdialog.h"
#include <QtWidgets/qwidget.h>
#include "QtWidgets/QMessageBox"
#include "QtWidgets/qcombobox.h"
#include  "QtWidgets/qformlayout.h"
#include "QtWidgets/qspinbox.h"
#include "QtWidgets/qradiobutton.h"
#include "qstandarditemmodel.h"
#include "userinterface/qcombocheckbox.hpp"
#include "qlineedit.h"
#include "qcheckbox.h"
#include "qtextstream.h"
#include "qgroupbox.h"
#include "qlabel.h"


class CAbsDptUIFilterPanel : public QWidget
{
    Q_OBJECT
public: 
     some functions

private slots:
 void on_checkBox_showGallery_clicked();

   void onCheckBoxShowGalleryClicked(bool f_bool);
}

something.cpp
void CAbsDptUIFilterPanel::on_checkBox_showGallery_clicked()
{
    m_showGallerySamples = ui->checkBox_showGallery->isChecked();
}

void CAbsDptUIFilterPanel::onCheckBoxShowGalleryClicked(bool f_bool)
{
    m_showGallerySamples = f_bool;
}

I had noticed that moc file for this this file is not getting generated.

Can u clean , run qmake and build it.

Thanks,

Sumit

@Pradeep-Kumar tried many times

Pradeep Kumar

Can u delete the build folder then compile once again,

Thanks,

does some functions contain a constructor? if so, can you show it?
Basically, slots are not magically connected, you have to call QObject::connect in the constructor (or let uic take care of connections based by name)

@Sumit ,

Where is your connect statement for 2nd slot.

    m_mainWindow->addDockWidget(Qt::LeftDockWidgetArea, m_FilterPanelHolder_p);

    connect(ui->checkBox_showGallery,SIGNAL(clicked(bool)), this,SLOT(onCheckBoxShowGalleryClicked(bool)));
