在GtkBuilder XML的GtkDialog中使用预定义的响应ID？ [英] Using a predefined response ID in a GtkDialog in a GtkBuilder XML?
问题描述
有没有办法在 GtkDialog 中使用预定义的响应（例如， GTK_RESPONSE_OK ），编码ID？ Glade默认生成带有0的XML，并给我一个数字输入。虽然我想我可以输入-5，这似乎打破了一个常数点。
Is there any way to use a predefined response (e.g., GTK_RESPONSE_OK) in a GtkDialog, without hard-coding the ID? Glade generates XML with "0" there by default, and gives me a numeric entry. While I suppose I could enter -5, that seems to defeat the point of having a constant.
Glade XML看起来像这样：
The Glade XML looks like this:
<action-widgets>
<action-widget response="0">cancel-button</action-widget>
<action-widget response="0">connect-button</action-widget>
</action-widgets>
即使文档中的例子：
<action-widgets>
<action-widget response="3">button_ok</action-widget>
<action-widget response="-5">button_cancel</action-widget>
</action-widgets>
（这有点搞笑，因为它们使用-5（ GTK_RESPONSE_OK ）for < button_cancel ...）
(Which is a bit hilarious, given that they're using -5 (GTK_RESPONSE_OK) for "button_cancel"…)
推荐答案
从GTK 3.12开始，您可以使用nck-names作为响应。
Since GTK 3.12 you can use nck-names for the response.

gtkdialog: Allow specifying response IDs by nick in <action-widgets>
This makes it a lot more convenient for developers, as they don't
have to look up the numeric value of response IDs.
所以您现在可以做
so you can now do
<action-widgets>
<action-widget response="ok">button_ok</action-widget>
<action-widget response="cancel">button_cancel</action-widget>
</action-widgets>
