QT VS C++ 2005, QPushButton NOT FIRING!!!!!

[harleyskater]

I am new to qt and I am trying to build a new project with QT. I have a nice GUI built in my login form and everything is compiling great until I try to connect my button to a function using signals and slots.

First I tried to use the QT editor. I would use the slots and signals editor and I couldn't figure out how to get it to my functions in my .cpp then I tried to do it outside of the editor by adding the connect button to my cpp and my header. I can get it to compile but i get an error saying "irst-chance exception at 0x670e98d8 in TheWGE.exe: 0xC0000005: Access violation reading location 0xffffffff.
Unhandled exception at 0x670e98d8 in TheWGE.exe: 0xC0000005: Access violation reading location 0xffffffff. BREAK OR CONTINUE"

this is my thewge.cpp

#include "thewge.h"
#include <QtGui/QApplication>
#include <QSignalMapper>
#include <QPushButton>
 
TheWGE::TheWGE(QWidget *parent, Qt::WFlags flags)
	: QMainWindow(parent, flags)
{
 
	ui.setupUi(this);
 
	QObject::connect(LoginBtn, SIGNAL(clicked()), this, SLOT(accept()));
 
}
 
TheWGE::~TheWGE()
{
    //delete usrLineEdit;  
    //delete pwdLineEdit;
} 
 
void TheWGE::readSettings()
{
        //Set Focus to the right place
 
      /*  if (ui.usrLineEdit->text().trimmed().isEmpty() ) {
                ui.usrLineEdit->setFocus();
        } else {
                ui.pwdLineEdit->setFocus();
        } */
 
}
 
void TheWGE::accept()
{
//readSettings();
}

#include "thewge.h"
#include <QtGui/QApplication>
#include <QSignalMapper>
#include <QPushButton>

TheWGE::TheWGE(QWidget *parent, Qt::WFlags flags)
	: QMainWindow(parent, flags)
{

	ui.setupUi(this);

	QObject::connect(LoginBtn, SIGNAL(clicked()), this, SLOT(accept()));

}

TheWGE::~TheWGE()
{
    //delete usrLineEdit;  
    //delete pwdLineEdit;
} 

void TheWGE::readSettings()
{
        //Set Focus to the right place

      /*  if (ui.usrLineEdit->text().trimmed().isEmpty() ) {
                ui.usrLineEdit->setFocus();
        } else {
                ui.pwdLineEdit->setFocus();
        } */

}

void TheWGE::accept()
{
//readSettings();
}

First: No need to SHOUT

Second, usrLineEdit, pwdLineEdit & LoginBtn don't seem to be initialised, so you will get an access violation.

Third, why not connect to controls in the ui class?

[harleyskater]

Haha sorry about the yelling :P

I think I have them initialized, I am in MSVS 2005 and I have the qt Addin. I will show my .ui and the header it generates, that header is where I think everything is being initailized.

I thought by including the ui header and adding the slot would connect the 2 together. Its a new concept to me! if I am connecting controls or linking them but this is how I would think I would do that. The ui header is generated, so I could copy the code from there and paste it into a new file and add more info in there. I tried adding the connect using this from the UI header and it doesn't fire, like so.

QObject::connect(LoginBtn, SIGNAL(clicked()), LoginBtn, SLOT(accept()));

Thanks for your help!

[squidge]

What I don't understand is that you have LoginBtn defined in both Ui_TheWGEClass and TheWGE. They are initialised by setupui() in Ui_TheWGEClass, but you are using the ones in TheWGE which seems puzzling. Why not just use the ones in Ui_TheWGEClass?

[harleyskater]

I am new to QT and after not getting my button to fire, I tried lots of things!

where should I put this:

QObject::connect(LoginBtn, SIGNAL(clicked()), LoginBtn, SLOT(accept()));

and I doubt it should be button to button, but I am not sure how to point it to the class holding the function

[squidge]

Have you tried :

QObject::connect(ui->LoginBtn, SIGNAL(clicked()), this, SLOT(accept()));

QObject::connect(ui->LoginBtn, SIGNAL(clicked()), this, SLOT(accept()));

[harleyskater]

yes I have tried that before, My attempt before was like this, I tried again and I got this set of errors. Though in my first attempt it was without the ui->LoginBtn, it was just LoginBtn

Why are you modifying ui_thewge.h? That file is automatically generated so you will loose your changes! Do not edit that file!

LOL, all of my posts on this thread have said that I don't know where to put the connect statement, it would be much easier if you just told me where it belongs

[wysota]

Your problem has nothing to do with Qt, you know. It's pure lack of C++ skills. Sorry for being blunt but then you didn't have to SHOUT(!) in the first place and you could have used proper tags in your posts

[harleyskater]

i've already built this, in managed code with .net forms in C++, but I want to get away from that with QT so my program will be more secure. I've only been programming C++ for a year, im no pro but Its not that I don't know C++. why can I put 6 posts in 1 thread with all my code asking why a button isn't firing and still have not gotten any real advice?
