我试图使用杂乱-gtk。我写了一小段代码，创建一个gtk窗口，里面有一个杂乱的舞台。我尝试在舞台上获得鼠标按钮按下事件，但没有任何东西。gtk中的杂乱舞台不能处理舞台鼠标按下事件
下面是代码：当我点击舞台
#include <clutter/clutter.h>
#include <clutter-gtk/clutter-gtk.h>
#include <glib.h>
#include <stdlib.h>
#include <stdio.h>
/*gcc 3_clutter_app_clickable_text_in_gtk.c -o 3_clutter_app_clickable_text_in_gtk `pkg-config clutter-1.0 clutter-gtk-1.0 glib --cflags --libs`*/
/*mouse clic handler*/
void on_stage_button_press(ClutterStage *stage, ClutterEvent *event, gpointer data)
{
printf("ok\n");
}
int main(int argc, char *argv[])
{
if (gtk_clutter_init(&argc, &argv) != CLUTTER_INIT_SUCCESS)
return EXIT_FAILURE;
/*create the window*/
GtkWidget *window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_window_set_default_size (GTK_WINDOW (window), 640, 480);
/*destroy from window close all*/
g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
/*vertical box, 0 spacing*/
GtkWidget * box = gtk_box_new(GTK_ORIENTATION_VERTICAL,0);
/*add box in the window*/
gtk_container_add(GTK_CONTAINER(window), box);
/*create the cutter widget*/
GtkWidget *clutter_widget = gtk_clutter_embed_new();
gtk_widget_set_size_request (clutter_widget, 200, 200);
ClutterActor *stage = gtk_clutter_embed_get_stage (GTK_CLUTTER_EMBED(clutter_widget));
clutter_stage_set_use_alpha(CLUTTER_STAGE(stage), TRUE);
ClutterColor stage_color ;
GString * bg_color = g_string_new("#555753ff");
clutter_color_from_string(&stage_color,bg_color->str);
clutter_actor_set_background_color(stage, &stage_color);
/*add the cutter widget in the box expand and fill are TRUE and spacing is 0*/
gtk_box_pack_start (GTK_BOX (box), clutter_widget, TRUE, TRUE, 0);
/*create line text*/
ClutterColor text_color;
GString * fg_color = g_string_new("#00000055");
clutter_color_from_string(&text_color, fg_color->str);
ClutterActor *some_text = clutter_text_new_full("Sans 24", "Hello, world", &text_color);
clutter_actor_set_size(some_text, 256, 128);
clutter_actor_set_position(some_text, 128, 128);
clutter_actor_add_child(CLUTTER_ACTOR(stage), some_text);
clutter_text_set_editable(CLUTTER_TEXT(some_text), TRUE);
/*define clic event*/
g_signal_connect(stage, "button-press-event", G_CALLBACK(on_stage_button_press), NULL);
/* Show the window and all its widgets: */
gtk_widget_show_all (GTK_WIDGET (window));
/* Start the main loop, so we can respond to events: */
gtk_main();
return EXIT_SUCCESS;
}
什么也没有发生。我做了一些测试，我可以在主窗口上处理clutter_widget上的click事件，但不能直接在杂乱的舞台上处理。
此代码从http://www.openismus.com/documents/clutter_tutorial/0.9/docs/tutorial/html/sec-stage-widget.html修改一个。在这篇文章中，作者直接在舞台上连接信号，但这个例子是针对杂波0.9的，并且当杂波v> 1.0时不再编译。
关于我在做什么的错误？
编辑
我已经取得了一些测试与“按键事件”，它的处理方式。所以这个问题似乎来自舞台的事件面具。
有没有人知道如何改变舞台的事件掩码以强制舞台对鼠标事件作出反应？
