I installed gtk on ubuntu with command sudo apt-get install libgtk-3-dev
then I copied code into vi editor
I copied the following code for helloworld in GTK which gives compile error
#include <gtk/gtk.h>
/* this is a callback function. the data arguments are ignored in this example..
* More on callbacks below. */
void hello (GtkWidget *widget, gpointer *data)
{
g_print ("Hello World\n");
}
/* another callback */
void destroy (GtkWidget *widget, gpointer *data)
{
gtk_main_quit ();
}
int main (int argc, char *argv[])
{
/* GtkWidget is the storage type for widgets */
GtkWidget *window;
GtkWidget *button;
/* this is called in all GTK applications. arguments are parsed from
* the command line and are returned to the application. */
gtk_init (&argc, &argv);
/* create a new window */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
/* when the window is given the "destroy" signal (this can be given
* by the application, or the window manager, the function destroy
* will be called as defined above. The data passed to the callback
* function is NULL and is ignored in the callback. */
gtk_signal_connect (GTK_OBJECT (window), "destroy",
GTK_SIGNAL_FUNC (destroy), NULL);
/* sets the border width of the window. */
gtk_container_border_width (GTK_CONTAINER (window), 10);
/* creates a new button with the label "Hello World". */
button = gtk_button_new_with_label ("Hello World");
/* When the button receives the "clicked" signal, it will call the
* function hello() passing it NULL as it's argument. The hello() function is
* defined above. */
gtk_signal_connect (GTK_OBJECT (button), "clicked",
GTK_SIGNAL_FUNC (hello), NULL);
/* This will cause the window to be destroyed by calling
* gtk_widget_destroy(window) when "clicked. Again, the destroy
* signal could come from here, or the window manager. */
gtk_signal_connect_object (GTK_OBJECT (button), "clicked",
GTK_SIGNAL_FUNC (gtk_widget_destroy),
GTK_OBJECT (window));
/* this packs the button into the window (a gtk container). */
gtk_container_add (GTK_CONTAINER (window), button);
/* the final step is to display this newly created widget... */
gtk_widget_show (button);
/* and the window */
gtk_widget_show (window);
/* all GTK applications must have a gtk_main(). Control ends here
* and waits for an event to occur (like a key press or mouse event). */
gtk_main ();
return 0;
}
then I compiled with
gcc -Wall -g HelloWorld.c -o hello_world -L/usr/X11R6/lib -lglib -lgdk -lgtk -lX11 -lXext -lm
it gives compile error
- HelloWorld.c:4:25: fatal error: gtk/gtk.h: No such file or directory #include
where locate gtk.h gives /home/user/linux-3.13.0/tools/perf/ui/gtk/gtk.h
I would like to use gtk for trvelling from one GPS co-ordinate to another using shortest path. Is it possible? what about gtkmap API? Where can I find more details and examples?
