#include <gtk/gtk.h>

//GdkRGBA rgba_color; //gtk3.0
GdkColor rgb_color; //gtk2.0

typedef GtkWidget *PGtkWidget;
int main (int argc, char* argv[])
{
        PGtkWidget window, button, vbox;

        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), 300, 300);

        button = gtk_button_new_with_label("Hello world!");

        //背景色设定
        //gdk_color_parse("blue", &rgb_color); //gtk2.0
        //gdk_rgba_parse(&rgba_color, "blue"); //gtk3.0
        //gtk_widget_modify_bg(button, GTK_STATE_NORMAL, &rgb_color);//gtk2.0
        //gtk_widget_override_background_color(button, GTK_STATE_NORMAL, &rgba_color);//gtk3.0

        //前景色设定
        gdk_color_parse("red", &rgb_color);//gtk2.0
        //gdk_rgba_parse(&rgba_color, "blue"); //gtk3.0
        gtk_widget_modify_fg(button, GTK_STATE_NORMAL, &rgb_color);//gtk2.0
        //gtk_widget_override_color(button, GTK_STATE_NORMAL, &rgba_color);//gtk3.0

        vbox = gtk_vbox_new(TRUE, 0);//gtk2.0
        //vbox = gtk_box_new(GTK_ORIENTATION_VERTICAL, 0);//gtk3.0
        gtk_box_pack_start(GTK_BOX(vbox), button, FALSE, FALSE, 0);
        gtk_container_add(GTK_CONTAINER(window), vbox);

        g_signal_connect(window, "delete_event", gtk_main_quit, NULL);
        gtk_widget_show_all(window);
        gtk_main();
        return 0;
}

终端里输入:

gcc -Wall -o color_button color_button.c $gtk2

其中gtk2是我为了方便而自定义的一个环境变量，具体内容大家懂的，不废话。
