Hey all.

I am working on this application in C with GTK, i wouldt like to add scrollbars to the text view. but i have no idear how to do this. i have searched on google but can't find anything to get me in the right direction.

Heres the code.
----------------------------------------------------------------------------------------
#include <gtk/gtk.h>

update_statusbar(GtkTextBuffer *buffer,
GtkStatusbar *statusbar)
{
gchar *msg;
gint row, col;
GtkTextIter iter;

gtk_statusbar_pop(statusbar, 0);

gtk_text_buffer_get_iter_at_mark(buffer,
&iter, gtk_text_buffer_get_insert(buffer));

row = gtk_text_iter_get_line(&iter);
col = gtk_text_iter_get_line_offset(&iter);

msg = g_strdup_printf("Col %d Ln %d", col+1, row+1);

gtk_statusbar_push(statusbar, 0, msg);

g_free(msg);
}

static void
mark_set_callback(GtkTextBuffer *buffer,
const GtkTextIter *new_location, GtkTextMark *mark,
gpointer data)
{
update_statusbar(buffer, GTK_STATUSBAR(data));
}

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

GtkWidget *window;
GtkWidget *vbox;

GtkWidget *toolbar;
GtkWidget *view;
GtkWidget *statusbar;
GtkToolItem *open;
GtkToolItem *new;
GtkToolItem *find;
GtkToolItem *save;
GtkTextBuffer *buffer;

gtk_init(&argc, &argv);

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_window_set_default_size(GTK_WINDOW(window), 800, 600);
gtk_window_set_title(GTK_WINDOW(window), "Escriba");

vbox = gtk_vbox_new(FALSE, 0);
gtk_container_add(GTK_CONTAINER(window), vbox);

toolbar = gtk_toolbar_new();
gtk_toolbar_set_style(GTK_TOOLBAR(toolbar), GTK_TOOLBAR_ICONS);

find = gtk_tool_button_new_from_stock(GTK_STOCK_FIND);
gtk_toolbar_insert(GTK_TOOLBAR(toolbar), find, 0);

save = gtk_tool_button_new_from_stock(GTK_STOCK_SAVE);
gtk_toolbar_insert(GTK_TOOLBAR(toolbar), save, 0);

open = gtk_tool_button_new_from_stock(GTK_STOCK_OPEN);
gtk_toolbar_insert(GTK_TOOLBAR(toolbar), open, 0);

new = gtk_tool_button_new_from_stock(GTK_STOCK_NEW);
gtk_toolbar_insert(GTK_TOOLBAR(toolbar), new, 0);

gtk_box_pack_start(GTK_BOX(vbox), toolbar, FALSE, FALSE, 3);

view = gtk_text_view_new();
gtk_box_pack_start(GTK_BOX(vbox), view, TRUE, TRUE, 5);
gtk_widget_grab_focus(view);

buffer = gtk_text_view_get_buffer(GTK_TEXT_VIEW(view));

statusbar = gtk_statusbar_new();
gtk_box_pack_start(GTK_BOX(vbox), statusbar, FALSE, FALSE, 0);

g_signal_connect(buffer, "changed",
G_CALLBACK(update_statusbar), statusbar);

g_signal_connect_object(buffer, "mark_set",
G_CALLBACK(mark_set_callback), statusbar, 0);

g_signal_connect_swapped(G_OBJECT(window), "destroy",
G_CALLBACK(gtk_main_quit), NULL);

gtk_widget_show_all(window);

update_statusbar(buffer, GTK_STATUSBAR (statusbar));

gtk_main();

return 0;
}
------------------------------------------------------------------------------------------

Any help is greatly appriciated.

Hi,

Add your vbox into scroll window.
as like:

Code: (C)

GtkWidget* scrolledwin;
scrolledwin = gtk_scrolled_window_new(NULL,NULL);
gtk_container_set_border_width(GTK_CONTAINER(scrolledwin), 0);
gtk_widget_set_size_request(scrolledwin, 800, 600);
gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(scrolledwin),GTK_POLICY_NEVER,GTK_POLICY_AUTOMATIC);
gtk_widget_show(scrolledwin);
gtk_container_add(GTK_CONTAINER(scrolledwin), vbox);
gtk_container_add(GTK_CONTAINER(window), scrolledwin);

Hope this code could be helpful for you.

Hi madsovenielsen:

Is pretty easy, keep your documentation open to see details about unknown APIs.
Also, try to learn more code basics
