GTK - 多个对象信号连接

Question

我的 gtk 程序中有很多按钮，它们具有相同的回调函数。如何避免重复。例如：

g_signal_connect(G_OBJECT(button1), "clicked", G_CALLBACK(button_clicked), data);
g_signal_connect(G_OBJECT(button2), "clicked", G_CALLBACK(button_clicked), data);
g_signal_connect(G_OBJECT(button3), "clicked", G_CALLBACK(button_clicked), data);
g_signal_connect(G_OBJECT(button4), "clicked", G_CALLBACK(button_clicked), data);

然后做这样的事情

g_signal_connect(G_OBJECT(four_buttons), "clicked", G_CALLBACK(button_clicked), data);

我该怎么做？提前致谢

Answer 1

使用循环：

GtkButton *buttons[] = { button1, button2, button3, button4 };
for (int index = 0; index < 4; index++)
    g_signal_connect(G_OBJECT(buttons[index]), "clicked", G_CALLBACK(button_clicked), data);
