Scrolled window problem

[prashanth km <prashanth_km22 yahoo com>]

hi all,

           I am using GTK2.0 for my application. i have a list box which i want to scroll. i used scrolled window (viewport)for that. but its not working.

my code is like this,

 

 

int main (int argc, char *argv[])

{

/* GtkWidget is the storage type for widgets */

GtkWidget *window;

GtkWidget *listbox;

GtkWidget *item;

GtkWidget *vbox;

GtkWidget *vbox1;

GtkWidget *scroll;

GtkWidget *button;

GtkWidget *frame;

GtkWidget *label;

gint i = 0, j = 0;

gchar *p[100];

DIR *dp;

stopFlg = 0;

MpengineStatus mpStatus_s;

struct dirent *ep;

/* This is the Window color code (blue) */

GdkColor col = {0, 0x0000, 0x0000, 0xffff};

GtkStyle *style;

pthread_t athread;

pthread_t bthread;

pthread_t cthread;

MpengineRet mpengine_ret;

/* Opening mediafiles directory and copied to Buffer */

dp = opendir ("./mediafiles");

if (dp != NULL) {

while (ep = readdir (dp)) {

//puts (ep->d_name);

p[i] = (char *)malloc (50);

strcpy (p[i], ep->d_name);

i++;

}

}

else

perror ("could not open directory\n");

/* calling MPEngine */

call_mpengine_open();

/* This is initialization of GTK */

gtk_init (&argc, &argv);

gtk_rc_parse ("pkm");

/* Creating new Window, setting title and size */

window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

gtk_window_set_title (GTK_WINDOW (window), "PlayList");

gtk_window_set_default_size (GTK_WINDOW (window), 320, 240);

gtk_widget_set_usize (window, 320, 240);

gtk_widget_set_size_request (window, 320, 240);

gtk_widget_set_name (window, "main_window");

/* Creating Listbox (playlist) & setting selection mode */

listbox = gtk_list_new ();

gtk_widget_set_name (listbox, "playlist");

gtk_list_set_selection_mode (GTK_LIST (listbox), GTK_SELECTION_BROWSE);

vbox = gtk_vbox_new (FALSE, 0);

scroll = gtk_scrolled_window_new (NULL, NULL);

frame = gtk_frame_new (NULL);

label = gtk_label_new ("Press S17 To Exit");

gtk_widget_set_name (label, "exit_label");

gtk_container_add (GTK_CONTAINER (frame), label);

gtk_label_set_markup (GTK_LABEL (label), "<b>Press S17 To Exit</b>");

j = i;

/* Adding files to the Listbox */

for (i = 2; i < j; i++) {

item = gtk_list_item_new_with_label (p[i]);

gtk_container_add (GTK_CONTAINER (listbox), item);

gtk_signal_connect (GTK_OBJECT (item), "toggle",

GTK_SIGNAL_FUNC (mpengine_opensource), p[i]);

gtk_signal_connect (GTK_OBJECT (item), "toggle",

GTK_SIGNAL_FUNC (listitem_selected), p[i]);

}

/* These are the signals */

gtk_signal_connect (GTK_OBJECT (window), "delete_event",

GTK_SIGNAL_FUNC (gtk_main_quit), NULL);

/*style = gtk_widget_get_style (window) ;

style->bg[GTK_STATE_NORMAL] = col;

gtk_widget_set_style (window, style);*/

gtk_scrolled_window_add_with_viewport (GTK_SCROLLED_WINDOW (scroll), listbox);

gtk_container_add (GTK_CONTAINER (vbox), scroll);

//gtk_box_pack_start (GTK_BOX (vbox), scroll,TRUE, TRUE, 0);

//gtk_box_pack_start (GTK_BOX (vbox), listbox, FALSE, TRUE, 0);

gtk_box_pack_start (GTK_BOX (vbox), frame, FALSE, TRUE, 0);

gtk_widget_set_usize (vbox, 320, 240);

GTK_POLICY_NEVER, GTK_POLICY_AUTOMATIC);

//gtk_scrolled_window_add_with_viewport (GTK_SCROLLED_WINDOW (scroll), listbox);

gtk_scrolled_window_set_shadow_type (GTK_SCROLLED_WINDOW (scroll), GTK_SHADOW_OUT);

/*button = gtk_button_new_with_label ("Close");

gtk_container_add (GTK_CONTAINER (vbox), button);

GTK_WIDGET_SET_FLAGS (button, GTK_CAN_DEFAULT);

gtk_box_pack_start (GTK_BOX(GTK_DIALOG (window)->action_area),button, TRUE, TRUE, 0);*/

gtk_container_add (GTK_CONTAINER (window), vbox);

/* Showing all widgets at the end */

gtk_widget_show_all (window).
