So I have to make a simple program in C using GTK for my class. So pretty much a window with 2 buttons, and an exit button below them. Then a popup asking if the user is sure if he wants to exit.
My problem is when I'm compiling, I don't understand why I am getting these errors or how to fix them. Please help me :).
For compiling I use: cc main.c -o win `pkg-config --clfags --libs gtk+-2.0`
(win:2654): Gtk-CRITICAL **: IA__gtk_container_add: assertion `GTK_IS_WIDGET (widget)' failed
(win:2654): Gtk-CRITICAL **: IA__gtk_table_attach: assertion `GTK_IS_TABLE (table)' failed
(win:2654): Gtk-CRITICAL **: IA__gtk_table_attach: assertion `GTK_IS_TABLE (table)' failed
(win:2654): Gtk-CRITICAL **: IA__gtk_widget_show: assertion `GTK_IS_WIDGET (widget)' failed
Code
Code:
#include <gtk/gtk.h>
void day(GtkWidget* w, gpointer data)
{
g_print("The sun comes out during the day.\n");
}
void night(GtkWidget*w, gpointer data)
{
g_print("The moon comes out during the night.\n");
}
gint delete_event(GtkWidget* w, GdkEvent* e, gpointer data)
{
g_print("Please use exit button\n");
return TRUE;
}
void destroy(GtkWidget* w, gpointer data)
{
gtk_main_quit();
}
int main(int argc, char** argv)
{
GtkWidget* win;
GtkWidget* button;
GtkWidget* table;
//////////Window//////////
