This code places an Elementary file selector button widget on a window, along with some other checkboxes and a text entry. Those are there just as knobs on the file selector button's state and to display information from it.
Here's how we instantiate it:
ic = elm_icon_add(win); elm_icon_standard_set(ic, "file"); evas_object_size_hint_aspect_set(ic, EVAS_ASPECT_CONTROL_VERTICAL, 1, 1); /* file selector button */ fs_bt = elm_fileselector_button_add(win); elm_fileselector_path_set(fs_bt, "/tmp"); elm_object_text_set(fs_bt, "Select a file"); elm_object_part_content_set(fs_bt, "icon", ic); elm_box_pack_end(vbox, fs_bt); evas_object_show(fs_bt);
Note that we set on it both icon and label decorations. It's set to list the contents of the "/tmp"
directory, too, with elm_fileselector_button_path_set(). What follows are checkboxes to exercise some of its API functions:
ck = elm_check_add(win); elm_object_text_set(ck, "editable selection"); elm_check_state_set(ck, elm_fileselector_is_save_get(fs_bt)); evas_object_smart_callback_add(ck, "changed", _current_sel_toggle, fs_bt); elm_box_pack_end(hbox, ck); evas_object_show(ck); ck = elm_check_add(win); elm_object_text_set(ck, "\"inwin\" mode"); elm_check_state_set(ck, elm_fileselector_button_inwin_mode_get(fs_bt)); evas_object_smart_callback_add(ck, "changed", _inwin_mode_toggle, fs_bt); elm_box_pack_end(hbox, ck); evas_object_show(ck); ck = elm_check_add(win); elm_object_text_set(ck, "folders only"); elm_check_state_set(ck, elm_fileselector_folder_only_get(fs_bt)); evas_object_smart_callback_add(ck, "changed", _folder_only_toggle, fs_bt); elm_box_pack_end(hbox, ck); evas_object_show(ck); ck = elm_check_add(win); elm_object_text_set(ck, "expandable"); elm_check_state_set(ck, elm_fileselector_expandable_get(fs_bt)); evas_object_smart_callback_add(ck, "changed", _expandable_toggle, fs_bt); elm_box_pack_end(hbox, ck); evas_object_show(ck); lb = elm_label_add(win); elm_object_text_set(lb, "Last selection:"); elm_box_pack_end(vbox, lb); evas_object_show(lb); en = elm_entry_add(win); elm_entry_line_wrap_set(en, EINA_FALSE); elm_entry_editable_set(en, EINA_FALSE); evas_object_smart_callback_add(fs_bt, "file,chosen", _file_chosen, en); elm_box_pack_end(vbox, en); evas_object_show(en);
The checkboxes will toggle whether the file selector button's internal file selector:
- must have an editable text entry for file names (thus, be in "save dialog mode")
- is to be raised as an "inner window" (note it's the default behavior) or as a dedicated window
- is to populate its view with folders only
- is to expand its folders, in its view, in place, and not repainting it entirely just with the contents of a sole directory.
The entry labeled "Last selection"
will exercise the "file,chosen"
smart event coming from the file selector button:
static void /* hook on the sole smart callback */ _file_chosen(void *data, Evas_Object *obj EINA_UNUSED, void *event_info) { Evas_Object *entry = data; const char *file = event_info; if (file) { elm_object_text_set(entry, file); printf("File chosen: %s\n", file); } else printf("File selection canceled.\n"); } /* toggle inwin mode */
Whenever you dismiss or acknowledges the file selector, after it's raised, the event_info
string will contain the last selection on it (if any was made).
