問題描述

目前我經常使用 FileChooser 并且我沒有在 文檔.小部件很棒，但是如果有人想刷新顯示的文件，則需要從當前目錄移動以刷新文件.

Currently I'm working with FileChooser a lot and I didn't find any mention of refreshing the widget in the docs. The widget is awesome, but if someone wants to refresh shown files, a movement from current directory is necessary to refresh files.

問題是當你有一個 single 目錄作為 rootpath 并且里面只有文件時，因此不可能進行這樣的移動.

The problem is when you have a single directory as a rootpath and inside are only files, therefore no such movement is possible.

我的問題是如何刷新小部件，如果我想避免任何浪費的刪除/添加 FileChooser 并盡可能縮短 FileChooser 非常嵌套在 kv 文件中.

My question was how to refresh the widget if I want to avoid any wasteful removing/adding of FileChooser and do it as short as possible for a FileChooser that is very nested in a kv file.

推薦答案

我搜索了 filechooser.py 找到了 code 在目錄之間的每次移動時觸發.考慮到 FileChooserIconView 和 FileChooserListView 繼承自 FileChooserController 的事實，對函數的訪問很簡單，不需要額外的導入.

After I searched filechooser.py I found the code which is triggered on each movement between directories. Giving the fact the FileChooserIconView and FileChooserListView inherit from FileChooserController, the access to the function is simple and no additional imports are required.

假設我們有 filechooser = FileChooserIconView():

filechooser._update_files() 運行良好，當 FileChooser 嵌套在某處時，使用 id

filechooser._update_files() works well and when is FileChooser nested somewhere, it's easy to access it with id

如需更多調整，Clock.schedule_interval(filechooser._update_files, t) 可能會對您在合理時間內更新目錄內容有所幫助.

For more tweaks Clock.schedule_interval(filechooser._update_files, t) may be helpful where you can update your directory content within a reasonable time.

(我在這里添加它，因為我沒有發現它，但是它可能對某人有用.)

(I add it here, because I found no mention of it, however it may be useful to someone.)
