c - 库存 GTK 按钮不显示？

Question

我在 CodeBlocks (Windows 7) 中使用 GTK，并尝试创建 gtk_button_new_from_stock 所以我使用了以下代码:

#include <stdlib.h>
#include <gtk.h>

int main(int argc, char **argv)
{
    GtkWidget* Window=NULL ,  *Btn = NULL;

    gtk_init(&argc, &argv);
    Window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_default_size(GTK_WINDOW(Window), 320 ,200);


    g_signal_connect(G_OBJECT(Window), "destroy", G_CALLBACK(gtk_main_quit),    NULL);


    Btn = gtk_button_new_from_stock(GTK_STOCK_QUIT);
    g_signal_connect(G_OBJECT(Btn), "clicked", G_CALLBACK(gtk_main_quit), NULL);
    gtk_container_add(GTK_CONTAINER(Window), Btn);

    gtk_widget_show_all(Window);

    gtk_main();
    return EXIT_SUCCESS;
}

问题是:该按钮不显示图像。还有其他方法可以创建带有图像的按钮吗？

Answer 1

使用GTK_ICON_SIZE_BUTTON设置图像的大小:

GtkWidget *button;
GtkWidget *image;

button = gtk_button_new();
image = gtk_image_new_from_stock(GTK_STOCK_QUIT, GTK_ICON_SIZE_BUTTON);
gtk_button_set_image(GTK_BUTTON(button), image);
