Hi raster, hi all.
I'm working on the elementary version of edje_editor and I need to write
some new widgets.
I started with the File Selector widget because it is also mentioned in the
elementary TODO ;)
Attached you can find the first patch that add the new widget and a new test
page.
I have also posted the patch at: http://pastebin.com/m1396006
...for fast reading, or in the case I have problems with attachment ;)
I try to make it more 'elementary' as I can: It fit well also on small
screen!
a screenshot is at: http://imagebin.ca/view/t8ZiuW.html
The current API: Evas_Object *elm_fileselector_add(Evas_Object *parent);
const char* elm_fileselector_selected_get(Evas_Object *obj);
void elm_fileselector_path_set(Evas_Object *obj, const char *path)
void elm_fileselector_expandable_set(Evas_Object *obj, Eina_Bool
expand);
I have some questions:
* Should the file elm_fileselector.c be named elc_ instead of elm_ ?? elc_
means complex? and what means els_?
* In the fileselector widget I show the subwidgets on elm_fileselector_add
(like in elc_notepad.c). Is this right? or is better to show/hide
all subs in the obj SHOW/HIDE smartcallback ?? so that we can corretcly
use evas_object_show/hide(fileselector)
And this is the todo for the widget
+/*
+ * TODO
+ * userdefined icon/label callback
+ * show/hide/add buttons ???
+ * need a background ???
+ * save mode (you can type a name somewhere)
+ * show/Hide hidden files
+ * double click to choose a file
+ * find a way to 'sort directory first'
+ * multiselection
+ * write docs
+ */
What do you think? some suggestions?
Hope you like it.
