我尝试用gnome-builder编写GUI程序,并尝试使用Glade进行布局。我在Programmer's Notes上做了一个教程。
#include <gtk/gtk.h>
int main(int argc, char *argv[]){
GError *err = NULL;
GtkBuilder *builder;
GtkWidget *window;
gtk_init(&argc, &argv);
builder = gtk_builder_new();
gtk_builder_add_from_file (builder, "window_main.ui", &err);
if (err != NULL) {
fprintf (stderr, "Unable to read file: %s\n", err->message);
g_error_free(err);
return 1;
}
window = GTK_WIDGET(gtk_builder_get_object(builder, "window_main"));
if (window == NULL || !GTK_IS_WINDOW(window)) {
fprintf (stderr, "Unable to get window. (window == NULL || window != GtkWindow)\n");
return 1;
}
gtk_builder_connect_signals(builder, NULL);
g_object_unref(builder);
gtk_widget_show(window);
gtk_main();
return 0;
}
void on_window_main_destroy(GtkWidget *widget, gpointer user_data){
gtk_main_quit();
}
<?xml version=1.0 encoding="UFT-8"?>

.glade文件位于src / direction中,就像.c文件一样。
当我运行代码时,返回以下错误消息
Unable to read file: Failed to open file “./window_main.ui”: No such file or directory
我不知道应该把林间空档文件放在哪里,因为当我编译自己的时候
gcc main.c -Wall 'pkg-config --cflags --libs gtk+-3.0' -export-dynamic
并使用./a.out
运行它,窗口打开时没有任何错误。
答案 0 :(得分:3)
正如评论区域TingPing所述,最好的方法是将其包含在GResource中。在您的情况下,资源规范XML将类似于
<?xml version="1.0" encoding="UTF-8"?>
<gresources>
<gresource prefix="/main">
<file>window_main.ui</file>
</gresource>
</gresources>
您使用gtk_builder_new_from_resource()
加载资源,例如
GtkBuilder *builder = gtk_builder_new_from_resource("/main/window_main.ui");
