I would like to associate my program with several file extensions programatically.
Everything I've been finding online is how a user would set a file association, does anyone know how to do this progormatically (bash, C++, etc)?
I would mostly like to get this to work with Gnome, but KDE would be nice as well.
Is it possible to do the following in C/C++ in Linux:Without direct linking (my program should NOT depend on Qt or GTK), display a GTK or Qt based file dialog.The behaviour should be something like this when my program runs, when you want to open a file:The program scans whether you have Qt installed. If so, it somehow manages to link itself to Qt (e.g. dynamically loading the .so file) and display its file dialog and get the path from it. If Qt wasn't found, it tries the same with GTK. If that also wasn't found, it displays a less powerful replacement dialog instead (better than nothing).
Or is there any other simple way in Linux to get a standard file dialog somehow (similar to when compiling for Windows you can very easily get its standard file dialog, no matter what version of Windows, in your code, even if your program doesn't use any other Windows GUI at all).
How do I change the default file associations in F15/gnome 3? My system is currently set to open .tex files with emacs. But I prefer TeXworks, and while TeXworks shows up in the "Open With" menu, it would be convenient if double-clicking on a tex file opened it in TeXworks. In gnome2, the "Open with-->Other application" option let me select the default program associated with a particular type of file, but this functionality seems to be gone in Gnome 3. Do I have to edit some config file?

Yesterday on my laptop I minimized Konqueror file browser and did something else for 10 minutes. When I went back to Konqueror no files would open; any file type asked for an app to use.
I found even in KDE settings/file associations everything had disappeared. No file type any longer has an app associated with it. Worse, if I assign one it doesn't 'take'. I haven't deleted anything or installed/updated anything, and I restored ~/kde/share/apps and ~/kde/share/config from backups but no joy.
I figure I may have a corrupted or missing data file, but which one?
I've edited the default file list association; sudo gedit/etc/gnome/defaults.list replacing all the totem.desktop with vlc.desktop (ctrl+H). however I don't understand how but VLC opens only certain files such as .flac, .wmv but not .mp3, .avi
View 9 Replies View RelatedI would like to change some of the file associations. for example, I like to exaile and every time I click on a mp3 I end up 'pulling' up totem the movie player. I have seen in the past but do not use this feature that much so have forgotten.
View 1 Replies View RelatedI know Dolphin/Konqueror is the manager of choice while in KDE, but I prefer Nautilus, mostly because I'm used to it. If I launch either a pure Openbox or Gnome session, Nautilus works perfectly fine. If I launch a KDE or KDE/Openbox session, Nautilus seems to 'forget' all the file associations for... well, pretty much everything. Thumbnail image previews and the mouse-over playing of audio files also seems to have stopped working, though these I can live without.
I looked into how Openbox handles it, and it seems to be that it launches 'Gnome services' to allow it, but I've not found exactly what those are, or how to launch them within KDE to fix Nautilus.
This is on Debian Lenny, with the KDE 4.3 repository containing the backport for Lenny enabled.
For some time (I don't remember exactly how long/since when, maybe since I switched to i3 window manager?) I have the problem from title.
Chromium browser uses completely different programs to open files than file browser (thunar). And most of the time thunar has associations I want. For example thunar opens PDFs with iceweasel, and chromium opens them with GIMP (!), note that I have never changed this king of settings. Until I changed it today chromium also used Baobab (I didn't even know it existed before I saw it) to open directories ("show file in directory" for downloaded files).
I know how to change for a single file type (at least for browser), but is there some way to set all file types to something sensible and keep both, browser and thunar in sync without doing all of that manually? Or at least revert it all to default?
Debian version: latest "testing" version. (I use testing because I really need up to date versions of a lot of programs)...
When using firefox to open a file attachment in web mail the update configuration runs but next time the same box appears to select which program to use , in firefox preferences / applications there is no way to add a new file association for a new filetype eg .doc or .xls ....!
I tried switching off suse integration with firefox but it made no difference .if anyone has a fix for for this i can save myself a lot of time .
Firefox version 3.5.9
open suse 11.2

I'm curious how file association management is implemented in Linux. Where is the related information stored? How do I modify it (I'm interested in non-KDE-based ways; I know there's a system configuration page for that in KDE)?
View 2 Replies View RelatedI am unable to double-click a file of a given type, e.g. .pdf, and have it open in the appropriate application. While some file types have the correct associations, others do not, and I am unable to assign apps for some file types.
An example is Adobe portable document files ending in .pdf. If I right-click on a .pdf in Nautilus, and select "Open with," I get a dialog containing two tabs. One lists applications already associated with that file type, which at present is blank. The other tab seems as if it should allow me to assign an application to that file type, but when I click it, the dialog simply closes suddenly, as if crashing.
What is going on here, and how do I fix it?
(Ubuntu 9.10 64-bit)
i initially installed ubuntu, working with gnome for a while. i now migrated to kde as i like it better. however, the kde session still has lots of the "old" file associations set as they are in gnome...
some examples? text files open in gedit, instead of kate pdfs open in "document viewer" instead of okular double clicking zip folder opens the "archiver" (gnome?), extracting an archive from the archiver and then pressing the "open folder" dialog after extracting has finished, opens nautilus (although dophin is the default program for inodes). etc.
i'm aware of the possibility to edit file associations, however thats a tedious thingy to do, if you want to get it complete... furthermore, the file association edit dialog has the "defaults" button disabled, hence my questions:
is there any way to "restore" the kde default file associations, just as i would have installed kubuntu initially? i don't want to reinstall just because of this.
I have my default text files (also source codes etc.) associated with gedit (checked with ubuntu tweak).However, nautilus tries it to open with some "notepad" - dunno what it is I don't even have such a program. Files are OK, opening them directly from gedit or vim is fine.Some weird things:- nautilus correctly displays gedit icon- I have dualboot system with windows 7 and notepad command looks like it came from "there"- when I click on open with -> gedit, file is correctly open. However this option is not remembered by nautilus (even though I checked it as always open with ...)- nautilus (after clicking on open with) also suggest to use some "iexplore" command, I totally don't have idea where that came from Any suggestions? I really don't feel like using another file manager, but opening text files is pretty elementeray action and should work properly
View 9 Replies View RelatedI recently upgraded to Fedora 15 and am super-happy with it. Unfortunately, I have a minor issue that I haven't yet figured out how to fix: I can't change the default applications or the file type associations. For instance, I'd like to set Chromium as my default browser. When I first login, I tell it to set itself as default. But after I end my session and log back it, Firefox is back to being the default browser.
I have the same issues when trying to change what applications open filetypes. .rtf files have been opening in Wordpad in Wine. When I try to change it to Writer through the "Open with" dialog, it retains the change for that session but resets after I log out. I actually ended up having to uninstall Calibre because it was opening .odt files instead of LibreOffice and I couldn't change it permanently.
How do i change file type associations? i looked but i don't see anything...i'm having that problem where google chrome won't stya set as default and i fixed it in fedora by changing the file associations manually :-)

I've found little to no documentation about it.
View 1 Replies View RelatedOn Ubuntu 11.04, I have a need to use gnome-open from another application to open files in assigned applications. I think I understand how mime types are given in /usr/share/mime. I understand how default application associations are done in /usr/share/gnome/applications/defaults.list. I understand how update-desktop-database is used to maintain defaults.list. I know how to specify file associations (open with) from Nautilus. I understand how ~/.local/share/applications and ~/.local/share/mime override the system settings. I get all that.
What I don't understand is why the command gnome-open or double-clicking a file in nautilus, for certain file types (e.g. PDF), generates an error message:
Quote:
Could not display "<whatever file>". The location is not a folder.
The occurrences of application/pdf in the different applicable files all point to evince as the associated application.
By the way, mimeopen does work. What is the relationship between mimeopen and gnome-open? Manual pages for these commands are not helpful in understanding their operation.
In addition, I might throw in one other question. In the various .desktop files, I see that some application commands are enclosed in single quotes, but never the file name identifier, %f. If dealing with file/directory names with spaces in them, it would seem that quoting the '%f' would be important.
For the past few days my file associations have gone for a toss. For example : an icon on the desktop to open eclipse says eclipse.desktop and doesn't show the eclipse image when i right click a .bz2 file it doesn't show the extract here option for text files, a small bit of the text is showing outside the icon where it usually shows inside The same problems are present in nautilus as well as the desktop.
Need some quick help to reset these to the default.
Have attached a screenshot to show the issue.
Only "Favourites", "Run Command" and "Leave" is shown on the classic KDE menu, same thing when switching to Launcher Menu Style. Missing Applications and everything else. File associations is not working. Double clicking any type of file it asks to install the program and the known applications menu is empty.
I tried to add a new user, same problem with that. I also noticed that when running Chrome it asks to be the default web browser each time even when I say yes.
I have not been messing with anything, I suspect it happened during a update, but I got the exact same repositories on 2 other x64 machines where there is no problem.
I'm using KDE 4.6.0 from the factory repository.

I have a USB modem and a large C++ application that needs to detect whether that device is present or not. I was hoping to get advice for what the best method to do so would be. The only solution I've thought of is to parse the output of lsusb and look for the vendor and product ID of my device, but that seems a little hack-ish and inefficient. Is there a command or program that I can provide it a vendor/product ID for a USB device and it can tell me whether or not such a device is present in the system? Or another, better way to detect the device than parsing the lsusb output that I've been thinking

I do not have Gtk::Settings and I have looked in ~/.gconf/desktop/gnome/ but I do not have an interface folder and none of the others I opened have any font details.

I have a default installation of Ubuntu 10.4 with Unity running on top of Gnome. (I think this is correct. I certainly can get Nautilus running quite easily and as I mentioned earlier I have ~/.gconf/desktop/gnome/ folders).
The brief is to get the application working on the default installation so I cannot install anything but the target machine I am using has got 'gconftool'.
I need to generate pdf documents programmatically using Ruby. i.e. I don't want a GUI interface but an API interface. The bulk of my document is text but there are images included as well. I've looked at this thread: [URL] and it's 2 main recommendations PDFEdit and ImageMagik. PDFEdit has scripting available but I can't get my head round how to call this using Ruby. ImageMagik has a number of Ruby wrappers and is the kind of thing I want but as far as I can tell it only deals with Images and my stuff is mainly text.
View 1 Replies View RelatedI am writing an application that has a web service client on a Windows PC that needs to call a web service on a Linux server. In order to create the client, I need to be able to programmatically read the WSDL on the server and use it to create the client. I'm using the web tools in MyEclipse to build the client.
The Linux server is running Red Hat, I believe, with ssh enabled. I can connect from Linux to Windows with no problem, but I can't reach the Linux box from Windows. I get one of three errors when I try: no path to host, connection reset, or unknown error number, depending on the port I use. I've googled for an answer, but haven't found anything yet.Is there some way to add the Windows IP to a permission file on the Linux machine so it will be recognized when it queries for the WSDL?
I wonder if there's a way to capture the same information I can get from nethogs to a file. All I need it per process (rather than per interface) what is the sent/received traffic.
