Question

在我的GUI中，我有一个listview，我想在其中更改单元格的值。我已经尝试了所有内容，每次调用lv_modify()时它都会返回0，这意味着出现了错误 - 这也意味着更改无法完成......

这是我的示例脚本 - 您应该能够像这样运行它。右键单击任何listview控件中的项目，然后尝试编辑文本。消息框报告变量。

我哪里错了？

[更新]

尽管在lv_modify之前调用'gui，mainui：listview，％current_listview％'，但看起来对默认列表视图的访问仍然丢失。但是lv_modify如果没有在ListViewEditorACCEPT子中调用，则可以正常工作。

Answer 1

啊！诀窍是将线程操作重置回主GUI。当我们打开第二个GUI窗口时，它接管了线程操作。

这是ListViewEditorACCEPT sub。

的尾端

;Reset the thread operation to the main GUI
gui, mainui:default

;Now reset the default listview
gui, mainui:listview, %current_listview%

无法更新listview
