[Solved] [C++,Gtkmm2] custom FileFilter

linux-ka · 2013-08-22 13:14:39

Hi,

could some help me to understand how to create my own FileFitler entry?

The documentation just mentions the prototype of the function :

void Gtk::FileFilter::add_custom ( FileFilterFlags needed, const SlotCustom& slot 	)

But honestly, it doesn't help me much. Maybe there is some code sniplet out there demonstrating the application of this function. Unfortunatelly, I did not find anything on my way through the internet :-\

I would be glad, if someone could help me!!!

Cheers,

L-K

Hey!

In advance: I am not very familiar with GTK and any of the smilarly named projects, but I felt like looking into it and found out a little that might just help you further

First of all, code that uses this function is indeed hard to find. But there seem to be a lot of wrappers for this UI toolkit in other languages.
Lots of sites show that the way for adding a custom FileFilter is just making an instance of one, assigning it a name and pattern
and passing that to the file selection dialog.
I have found the Vala gtkmm documentation to have a very good example for this.

Hopefully this helps

Thanks n0stradamus,

this somehow explains at least a bit what kind of parameter is expected, but it also lacks of examples....I guess I will ask on the Gtkmm page directly and post the solution later on (if there will be one)...

Alright, I hope that you'll find it out.
If you do so, why don't you post your findings here, so that at least one hit on google will be useful?

You are so right :-)

Since I was interested in setting a filter for specific file extensions (which are not covered by mime-types), I got the following repsonse via mailing-list; for the ease of application simply set the filter via

add_pattern("*.dat")

or any extension you might need. This works pretty good :-)
