File Explorer

Browse the filesystem through an LVGL widget.

File explorer with quick access

Open a file explorer on the active screen and log the selected path.

lv_file_explorer_create builds a full-screen browser, lv_file_explorer_set_sort sorts entries by LV_EXPLORER_SORT_KIND, and lv_file_explorer_open_dir opens the platform root ("C:C:/" on Win32 or "A:/" on the lv_fs Linux driver). When LV_FILE_EXPLORER_QUICK_ACCESS is enabled, HOME, VIDEO, PICTURES, MUSIC, DOCS, and FS shortcuts are registered. An LV_EVENT_ALL callback prints the current path and the selected file name on every LV_EVENT_VALUE_CHANGED.

Quick access toggle and sort control

File explorer with a header button to hide quick access and a dropdown to change sort mode.

Adds a checkable button and a dropdown into the file explorer's header (lv_file_explorer_get_header). Toggling the button adds or removes LV_OBJ_FLAG_HIDDEN on the quick access panel returned by lv_file_explorer_get_quick_access_area. The dropdown switches between LV_EXPLORER_SORT_NONE and LV_EXPLORER_SORT_KIND via lv_file_explorer_set_sort. A separate LV_EVENT_ALL handler logs the current path and selected file name.

Custom file explorer sort

Apply a 3-way quicksort over the file table after each directory load.

The file explorer is created with LV_EXPLORER_SORT_NONE so that default sorting stays out of the way. On LV_EVENT_READY, lv_file_explorer_get_file_table returns the underlying table and a static 3-way quicksort reorders rows by the kind column. LV_EVENT_VALUE_CHANGED still logs the current path and selected file name.
