problems

[IRON_MAN]

I´m doing 2 buttons one disabled the other one. To do that I have done the following that:

button.h

#ifndef BUTTONS_H
 #define BUTTONS_H
 
 #include <QWidget>
 #include <QBuffer>
 
 
 class QPushButton;
 
 class buttons: public QWidget
 {
     Q_OBJECT
 public:
	 buttons(QWidget *parent = 0);
 
private slots:
      void blocked();
 
 };
 
 #endif

#ifndef BUTTONS_H
 #define BUTTONS_H

 #include <QWidget>
 #include <QBuffer>


 class QPushButton;

 class buttons: public QWidget
 {
     Q_OBJECT
 public:
	 buttons(QWidget *parent = 0);

private slots:
      void blocked();

 };

 #endif

buttons.cpp

QPushButton *deshabilitar = new QPushButton(tr("deshabilitar"), this);
connect(deshabilitar, SIGNAL(clicked()),this, SLOT(blocked()));
 
QPushButton *Button7= new QPushButton(tr("Button7"), this);
 
void buttons:: blocked( )
 {
	    Button7.setDisabled(true);
 }

QPushButton *deshabilitar = new QPushButton(tr("deshabilitar"), this);
connect(deshabilitar, SIGNAL(clicked()),this, SLOT(blocked()));

QPushButton *Button7= new QPushButton(tr("Button7"), this);

void buttons:: blocked( )
 {
	    Button7.setDisabled(true);
 }

Why am I having problems?

make Button7 a member of buttons class.

how??? I have done like this but it doesn´t work.

#include <QtGui>
 #include <QPushButton>
 #include <QPixmap>
 #include <QIcon>
 
 #include "buttons.h"
 
 buttons::buttons(QWidget *parent)
     : QWidget(parent)
 {
 
 
QPushButton *deshabilitar = new QPushButton(tr("deshabilitar"), this);
connect(deshabilitar, SIGNAL(clicked()),this, SLOT(blocked()));
 
QPushButton *Button7= new QPushButton(tr("Button7"), this);
 
void buttons:: blocked( )
{
Button7.setDisabled(true);
}
}

#include <QtGui>
 #include <QPushButton>
 #include <QPixmap>
 #include <QIcon>

 #include "buttons.h"

 buttons::buttons(QWidget *parent)
     : QWidget(parent)
 {


QPushButton *deshabilitar = new QPushButton(tr("deshabilitar"), this);
connect(deshabilitar, SIGNAL(clicked()),this, SLOT(blocked()));

QPushButton *Button7= new QPushButton(tr("Button7"), this);

void buttons:: blocked( )
{
Button7.setDisabled(true);
}
}

class buttons: public QWidget
{
Q_OBJECT
public:
buttons(QWidget *parent = 0);
 
private slots:
void blocked();
 
//LOOK HERE
QPushButton *Button7;
 
 
};
 
#endif
 
buttons.cpp
 
QPushButton *deshabilitar = new QPushButton(tr("deshabilitar"), this);
connect(deshabilitar, SIGNAL(clicked()),this, SLOT(blocked()));
 
//LOOK HERE
//QPushButton *Button7= new QPushButton(tr("Button7"), this);
Button7= new QPushButton(tr("Button7"), this);
 
void buttons:: blocked( )
{
//FINALLY  LOOK HERE
//Button7.setDisabled(true);
Button7->setDisabled(true);
}

class buttons: public QWidget
{
Q_OBJECT
public:
buttons(QWidget *parent = 0);

private slots:
void blocked();

//LOOK HERE
QPushButton *Button7;


};

#endif

buttons.cpp

QPushButton *deshabilitar = new QPushButton(tr("deshabilitar"), this);
connect(deshabilitar, SIGNAL(clicked()),this, SLOT(blocked()));

//LOOK HERE
//QPushButton *Button7= new QPushButton(tr("Button7"), this);
Button7= new QPushButton(tr("Button7"), this);

void buttons:: blocked( )
{
//FINALLY  LOOK HERE
//Button7.setDisabled(true);
Button7->setDisabled(true);
}

make other buttons the member as well

[IRON_MAN]

it doesn't work

I take these errors:


a function-definition is not allowed here before '{' token botoiak.cpp btns 140 C/C++ Problem
make: *** [debug] Error 2 btns 0 C/C++ Problem
make[1]: *** [tmp/obj/debug_shared/botoiak.o] Error 1 btns 0 C/C++ Problem

[nish]

change this section to

private slots:
void blocked();
 
private://PUT THIS LINE
//LOOK HERE
QPushButton *Button7;

private slots:
void blocked();
 
private://PUT THIS LINE
//LOOK HERE
QPushButton *Button7;

hey.. are you doing all the code in the buttons contstructor?

[IRON_MAN]

sorry but I don't get it:

botoiak.h

#ifndef BOTOIAK_H
 #define BOTOIAK_H
 
#include <QtGui/QWidget>
 
 class botoiak : public QWidget
 {
     Q_OBJECT
 
 public:
	 botoiak(QWidget *parent = 0);
 
private slots:
      void blocked();
 
private:
      QPushButton *Button7;
 
 };
 
 #endif

#ifndef BOTOIAK_H
 #define BOTOIAK_H

#include <QtGui/QWidget>

 class botoiak : public QWidget
 {
     Q_OBJECT

 public:
	 botoiak(QWidget *parent = 0);

holy cow!!! you are inserting a slot defination inside the constructor...

botoiak.cpp
 
#include <QtGui>
#include <QPushButton>
#include <QPixmap>
#include <QIcon>
#include <QApplication>
#include "botoiak.h"
 
botoiak::botoiak(QWidget *parent)
: QWidget(parent)
{
 
QPushButton *habilitar = new QPushButton(tr("habilitar"), this);
 
QPushButton *deshabilitar = new QPushButton(tr("deshabilitar"), this);
connect(deshabilitar, SIGNAL(clicked()),this, SLOT(blocked()));
 
 
Button7= new QPushButton(tr("Button7"), this);
 
 
 
 
// setWindowTitle(tr("Botoiak"));
//resize(400,400);
}
 
//Move it here
void botoiak:: blocked( )
{
Button7->setDisabled(true);
}

botoiak.cpp

#include <QtGui>
#include <QPushButton>
#include <QPixmap>
#include <QIcon>
#include <QApplication>
#include "botoiak.h"

botoiak::botoiak(QWidget *parent)
: QWidget(parent)
{

QPushButton *habilitar = new QPushButton(tr("habilitar"), this);

QPushButton *deshabilitar = new QPushButton(tr("deshabilitar"), this);
connect(deshabilitar, SIGNAL(clicked()),this, SLOT(blocked()));


Button7= new QPushButton(tr("Button7"), this);




// setWindowTitle(tr("Botoiak"));
//resize(400,400);
}

//Move it here
void botoiak:: blocked( )
{
Button7->setDisabled(true);
}

thank you!! that was my big problem. Now it works.

[nish]

thx to god... if you have asked one more question i would have died.

[Lykurg]

if you could please use the [ CODE ] tags for further post, because then one could read your code better. Second you could simply use:

connect(deshabilitar, SIGNAL(clicked(bool)), Button7, SLOT(setEnabled(bool)));

connect(deshabilitar, SIGNAL(clicked(bool)), Button7, SLOT(setEnabled(bool)));

assuming you button is not checkable.
