[SOLVED] shared variable causing problem

[habbas33]

Hi i am new to object oriented programming and dont know how to get rid of this problem. here I intent to make three animation plots

@
subwindow_movie *child_Movie = new subwindow_movie;

child_Movie->setGeometry(20,100,620,560);

child_Movie->setplot(0);

child_Movie->show();

subwindow_movie *child_Movie1 = new subwindow_movie;
child_Movie1->setGeometry(680,100,620,560);
child_Movie1->setplot(1);
child_Movie1->show();


subwindow_movie *child_Movie2 = new subwindow_movie;

child_Movie2->setGeometry(325,350,620,560);

child_Movie2->setplot(2);

child_Movie2->show();

@

but the problem is that they all share same value of setplot i,e when the third subwindow_movie is created child_movie0 and child_movie1 both setplot values become 2; how to get rid of that... below is the set value funxtion inside the class

@
#include "subwindow_movie.h"

#include "ui_subwindow_movie.h"

#include "plot.h"

#include <qapplication.h>

#include <qmainwindow.h>

int movie;

subwindow_movie::subwindow_movie(QWidget *parent) :

QDialog(parent),

ui(new Ui::subwindow_movie)

{

ui->setupUi(this);

}

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

void subwindow_movie::setplot(int value)

{
if (value ==0)

 {   d_plot0 = new Plot( this );

     movie=0;}

 else if (value ==1)

 {   d_plot1 = new Plot( this );

     movie=1;}

 else if (value ==2)

 {   d_plot2 = new Plot( this );

     movie=2;}

}

void subwindow_movie::on_movie_slider_valueChanged(int value)

{
if (movie ==0)

{  d_plot0->setAlpha(value);

   }
else if (movie ==1)

{  d_plot1->setAlpha(value);

}
else if (movie ==2)

{  d_plot2->setAlpha(value);

}

}
@

the real problem is "int movie " which changes for with new child_movie

[edit: added missing coding tags @ SGaist]

solved using member variable for int movie instead of global
