c - g_signal_connect 鼠标右键单击？

Question

我得到的代码适用于鼠标左键单击按钮，但我将如何使用它来获取鼠标右键单击信号:

g_signal_connect(G_OBJECT(button), "clicked", G_CALLBACK(button-action), NULL);

Answer 1

监听任何鼠标点击的简单方法是这样的:

g_signal_connect(
    G_OBJECT(button)
    "button-press-event",
    G_CALLBACK(btn_press_callback),
    NULL
);

然后，对于回调函数:

gboolean btn_press_callback(GtkWidget *btn, GdkEventButton *event, gpointer userdata)
{
    if (event->type == GDK_BUTTON_PRESS  &&  event->button == 3)
    {//3 is right mouse btn
        //do stuff
        return true;//or false
    }
    if (event->type == GDK_BUTTON_PRESS  &&  event->button == 1)
    {//1 is left mouse btn
    }
}

等等... More info here .

一些示例，使用 GTK+-2 但仍然有用，can be found here .
