Hi All,

This is Sowmya Bandalli, I am trying to develop GUI for N800, I have created 5 colorbuttons and 5 labels in the hbox,but the problem is with the width,the GUI I developed is occupying the whole screen, So I want to reduce the width, I am very new in this field,So can someone help me with this, Thanks for all your help.

Best,
Sowmya

I am attaching the code which I have written.

#include <gtk/gtk.h>

static void color_changed (GtkColorButton*, GtkWidget*);
int i;

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

{
GtkWidget *window, *button, *label, *hbox;
GdkColor color;
int i;

gtk_init(&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_window_set_title (GTK_WINDOW (window), "Color Button");
gtk_container_set_border_width (GTK_CONTAINER (window), 10);
gdk_color_parse("#0065535", &color);
button = gtk_color_button_new_with_color (&color);
gtk_color_button_set_title (GTK_COLOR_BUTTON (button), "Select a Color");
hbox = gtk_hbox_new (FALSE, 3);

for(i=0; i<5; i++)
{
label = gtk_label_new ("mote1!");
gtk_widget_modify_fg(label, GTK_STATE_NORMAL, &color);
g_signal_connect (G_OBJECT (button), "color_set",G_CALLBACK (color_changed), (gpointer) label);
/*hbox = gtk_hbox_new (FALSE, 2);*/
gtk_box_pack_start_defaults (GTK_BOX (hbox), button);
gtk_box_pack_start_defaults (GTK_BOX (hbox), label);
button = gtk_color_button_new_with_color (&color);
gtk_color_button_set_title (GTK_COLOR_BUTTON (button), "Select a Color");
}

/*label = gtk_label_new ("mote1!");
gtk_widget_modify_fg(label, GTK_STATE_NORMAL, &color);
g_signal_connect (G_OBJECT (button), "color_set",G_CALLBACK (color_changed), (gpointer) label);
hbox = gtk_hbox_new (FALSE, 800);
gtk_box_pack_start_defaults (GTK_BOX (hbox), button);
gtk_box_pack_start_defaults (GTK_BOX (hbox), label);
button = gtk_color_button_new_with_color (&color);
gtk_color_button_set_title (GTK_COLOR_BUTTON (button), "Select a Color");

label = gtk_label_new ("mote1!");
gtk_widget_modify_fg(label, GTK_STATE_NORMAL, &color);
g_signal_connect (G_OBJECT (button), "color_set",G_CALLBACK (color_changed), (gpointer) label);
hbox = gtk_hbox_new (FALSE, 2);
gtk_box_pack_start_defaults (GTK_BOX (hbox), button);
gtk_box_pack_start_defaults (GTK_BOX (hbox), label);
button = gtk_color_button_new_with_color (&color);
gtk_color_button_set_title (GTK_COLOR_BUTTON (button), "Select a Color");*/

gtk_container_add (GTK_CONTAINER (window), hbox);
gtk_widget_show_all (window);

gtk_main();
return 0;

}

static void
color_changed (GtkColorButton *button, GtkWidget *label)
{
GdkColor color;
gtk_color_button_get_color (button,&color);
gtk_widget_modify_fg (label, GTK_STATE_NORMAL, &color);
}

Sizing in GTK+ generally does not use fixed sizes. This allows applications to accommodate all different types of fonts, sizes, themes, languages, etc. If it is really too large, you have a few options. One is to add a blank label as a third column in the table and set only that column to expand. Another option is to place it into a GtkAlignment widget, which allows proportional sizing.

You should really use a table rather than an hbox so that all of the labels are in the left column and the color buttons are in the right column. This is a cleaner design and more closely follows the GNOME Human Interface Guidelines.
