如何禁用 GTK3 中的按钮

Question

Windows API has a function called EnableWindow that disables controls so user can't interact with them any more.

Is there an equivalent for GTK3 or GTK3++?

Answer 1

gtk_widget_set_sensitive (widget, FALSE);

请注意，如果您需要检查小部件是否敏感， gtk_widget_get_sensitive()返回使用上述函数设置的值，而gtk_widget_is_sensitive()会告诉您小部件是否真的敏感——这也受父小部件敏感性的影响。

Answer 2

For specific control, I think you can use "set_sensitive":

var button = new Gtk.Button.with_label("Hello");

button.set_sensitive(false); // true to enable the button
