Problem with view on LCDNumber

[Danny Fan]

Hi All,
I start to learn the QT but I have some problem with an example that I'm try to develop.

This is the part of the code

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "QIntegerForSize"
#include "QTimer"
#include "QLabel"
#include "QString"
#include "mainwindow.h"
 
int a;
int c;
bool b;
 
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}
 
 
MainWindow::~MainWindow()
{
    delete ui;
}
 
void MainWindow::GreenUnoClick()
{
    if (b != true)
    {
        a = (a*10) + 1;
    }
    else
    {
        c = ui->lcdNumber->intValue();
        a = 1;
    }
 
    b = true;
    ui->lcdNumber->display(a);
    QTimer *timer = new QTimer(this);
    connect(timer, SIGNAL(timeout()), this, SLOT(AddValueLCD()));
    timer->setSingleShot(true);
    timer->start(5000);
 
}
 
void MainWindow::AddValueLCD()
{
    c = c + a;
    ui->lcdNumber->display(c);
}

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "QIntegerForSize"
#include "QTimer"
#include "QLabel"
#include "QString"
#include "mainwindow.h"

int a;
int c;
bool b;

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}


MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::GreenUnoClick()
{
    if (b != true)
    {
        a = (a*10) + 1;
    }
    else
    {
        c = ui->lcdNumber->intValue();
        a = 1;
    }

    b = true;
    ui->lcdNumber->display(a);
    QTimer *timer = new QTimer(this);
    connect(timer, SIGNAL(timeout()), this, SLOT(AddValueLCD()));
    timer->setSingleShot(true);
    timer->start(5000);

}

void MainWindow::AddValueLCD()
{
    c = c + a;
    ui->lcdNumber->display(c);
}

What I want do but is :
1st
When I press two time the button 1 in this case it write on the LCD "11" and not 1.
2nd
When the timer end it add to my start number not original + 1 + 1 but original + 1.

Somebody have the possibility to help me ?

Thank s in advance.
