Inheritance problem

[jpn]

It should be "SIGNAL(currentIndexChanged())" and "SLOT(typeChanged())". Notice upper case.

Good!

I've forgot it!
It's building right now, but when I run the program I have this output at shell:

hudson@brevleq:~/.projetos/CLP$ CLP
Object::connect: No such signal ComboView::QComboBox::currentIndexChanged()
Object::connect: No such signal ComboView::QComboBox::currentIndexChanged()
Object::connect: No such signal ComboView::QComboBox::currentIndexChanged()
Object::connect: No such signal ComboView::QComboBox::currentIndexChanged()

Object::connect: No such signal ComboView::QComboBox::currentIndexChanged()
Object::connect: No such signal ComboView::QComboBox::currentIndexChanged()

I wanna use QComboBox Signal, can I?? How?? Should I reimplement currentIndexChanged()??

Please post your updated connect() statement. It probably contains SIGNAL(QComboBox::currentIndexChanged()) instead of SIGNAL(currentIndexChanged()).

#include "ComboView.h"
 
ComboView::ComboView(QWidget *parent):QComboBox(parent){
	addItem("Constante",PortaEntrada::CONSTANT);
	addItem("Triangular",PortaEntrada::TRIANGULAR);
	addItem("Quadratica",PortaEntrada::QUADRATIC);
	connect(this,SIGNAL(currentIndexChanged(&int)),this,SLOT(typeChanged()));
}
 
void ComboView::typeChanged(void){
	controller->setProperty(currentIndex());
}

#include "ComboView.h"

ComboView::ComboView(QWidget *parent):QComboBox(parent){
	addItem("Constante",PortaEntrada::CONSTANT);
	addItem("Triangular",PortaEntrada::TRIANGULAR);
	addItem("Quadratica",PortaEntrada::QUADRATIC);
	connect(this,SIGNAL(currentIndexChanged(&int)),this,SLOT(typeChanged()));
}

void ComboView::typeChanged(void){
	controller->setProperty(currentIndex());
}

connect(this,SIGNAL(currentIndexChanged(&int)),thi s,SLOT(typeChanged()));

should be

connect(this,SIGNAL(currentIndexChanged(int)),this,SLOT(typeChanged()));

parent class have no currentIndexChanged signal, i think
