GTK 2 gtk_widget_add_accelerator错误：“GDK_Z”未声明

Question

我试图为GTK菜单项分配一个加速器：

group = gtk_accel_group_new();

item = gtk_image_menu_item_new_from_stock(GTK_STOCK_UNDO, group);

gtk_widget_add_accelerator(item, "activate", group, GDK_Z, GDK_CONTROL_MASK, GTK_ACCEL_VISIBLE);

但是，当我编译时，我会得到以下错误：

./src/main.c:171:55: error: ‘GDK_Z’ undeclared (first use in this function)
   gtk_widget_add_accelerator(item, "activate", group, GDK_Z, GDK_CONTROL_MASK, GTK_ACCEL_VISIBLE);
                                                       ^

这是pkg-config --cflags gtk+-2.0的输出

-pthread -I/usr/include/gtk-2.0 -I/usr/lib/x86_64-linux-gnu/gtk-2.0/include -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/libpng12 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng12 -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/freetype2

如何使GDK_Z标识符对我的程序可用？

Answer 1

你没有包括gdkkeysyms.h

#include <gdk/gdkkeysyms.h>

其中包含您的程序所需的GDK_Z。
