Bug 32163 – Provide a choose-file signal to allow implementing a custom file chooser

• Status: RESOLVED
• Resolution: WONTFIX
• Component: WebKitGTK

[Christian Dywan]

I would like to implement my own file chooser in Midori. For instance to preset the default folder with the last folder used in other file choosers in the application. I'm thinking of "choose-file" with a const gchar* default_filename and returning a gchar*. If the signal is not handled, it should just do the same that is done now.

Implement WebKitFileChooser and choose-file

So I implemented a choose-file signal. It passes a WebKitFileChooser object that has a select-multiple property and a uris GSList* property.

I'm not sure whether the object's name is ideal. I couldn't think of a better name. I'm open to suggestions if someone has a different idea.

It seems WebCore can't handle URIs, or at least the internal interface only expects local filenames. So the patch works but will fail if remote files are selected. I'm not sure if the current code would support that.

Updated, to include the new files.

Note to myself: I need to fix the documentation header, and add g_return*if_fail to public functions.

I'd also need such a signal for Browse, the Sugar browser (http://git.sugarlabs.org/projects/browse).

Afaik, file pickers aren't supposed to target remote URIs anyway. If the feature is needed, you'd have to download the remote URI yourself and pass a local file to the browser, to pass on to the server.

I've reviewed the patch and thinking from the p.o.v. of Python, the API looks alright.

I hope this will get merged as soon as possible.

Updated patch, added missing return_if_fail and changed uris to filenames because that's what is actually supported and useful.

This really needs a proper review by folks knowledgeable in GTK.  Some of the style errors look bogus, but some of them look like they should be addressed.  I'm going to mark this R- for now to remove it from the queue, but please feel encouraged to upload a new version of the paper.  You should probably find one of the gtk folks on IRC and ask them to take a look at your patch.

Cb = ?  I don't understand this abbreviation.

The wk1 API is about to be removed, and the wk2 API supports this use-case, so I think this bug is obsolete.
