Hi guys!

The idea is that you can configure the binary widget to select only certain file types.

maybe in the attributes of the xml:  
field name = “my\_binary\_field” file\_accept = “pdf”

or

file\_accept = “jpg, png”

I think it is the proper place as it is more a experience improvement than a validation constraint.

I would simply use the attribute `accept` with the same syntax as [the HTML input](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file#accept) because [Gtk as similar feature](https://developer.gnome.org/gtk3/stable/GtkFileFilter.html#gtk-file-filter-add-mime-type) (but it will need to distinct also from [pattern](https://developer.gnome.org/gtk3/stable/GtkFileFilter.html#gtk-file-filter-add-pattern).

hi ced!  
okay,  
in html it would be accepted more direct and combinable, using these types:  
[unique\_file\_type\_specifiers](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file#unique_file_type_specifiers)

in the xml of the view form it would be:  
accept = “. pdf, .doc”  
accept = “image / \* ,. pdf”  
accept = “. doc, .docx, application / msword, application / vnd.openxmlformats-officedocument.wordprocessingml.document”

and in gtk would you have to choose a single method internally? MIME type string?  
a loop that checks the string
