c++ - open file folder in the directory -

-

I want my C ++ application to implement the functionality of "open file folders" like my Firefox and download manager . This is the code that I have come up with. 

  int file :: openTempFile (std :: string temp_file_dir) {std :: string file_path = temp_file_dir + "/"; File_path = file_path + this- & gt; Additional_info; // If you already have a temporary file, delete it // if (temporary_file! = "") {//: TODO: open temporary file stack // // when app deinit we remove those // (Temporary_file.c_str ()); } / * Write temporary file * / file * fp = fopen (file_path.c_str (), "w"); If returned (fp == NULL) wrong; Filitt (m_data, 1, m_size, fp); Fclose (fp); // Now open it using Netlus / Four * Permalink [] = {strdup ("nautilus"), strdup (file_path.c_str ())}; Int pid; If ((pid = fork ()) == -1) Pillar ("Kanka Fail"); If (pd == 0) {int a = execvp ("notilis", permliext); Printf ("exevp failed to load temporary file"); } Temporary_file = file_path; Return TRUE; }

But instead of a Nautilus window, it opens up 3 windows.What is the reason for any idea? And instead of showing it, how can Nautilus open "dialogue" on the directory?

When opening a folder, I will call xdg-open Opens the specified folder with the specified desktop manager for.

When I am running KDE , then to display it dolphin calls , and xfce4 It invokes thunar , because it is the preferred file manager according to my settings. I do not want to use notilis because the interface is different from my favorite app, widgets In terms of style, other applications do not look consistent - and 'T group my taskbar There is only one.

It also uses different preferences for my default open-in settings, and struggles with my workflow.

Additionally, Nautilus is not necessarily guaranteed on my system, for example, on some of my older systems, where I have encountered On the custom Jeju system, where I am compelled by RAM or HDD space, only me to emerge D twm and xfce4 , hence the Nautilus is not present.

As far as Nautilus-specific behavior is concerned, I have similar problems with Nautilus, which creates a desktop on initial invitations (as I ran the twm 

  Application options: -C, - Check self-test trials. Set up quick. Show version of version --version -g, --geometry = geometry Create initial window with given geometry -w, --new-window Always open a new window to browse a specified URI- n, --no-default-window Clearly specified URI To create Windows only - no-desktop desktop should never be managed (g settings ignore priority). --force-desktop Always manage the desktop (ignore GSettings preferences) -k, - Skip some Nautilus -s, - Select the specified URI in the original folder. Unfortunately, I can not help you use the "Open with ..." dialog, especially  Nautilus , though

code> Xdg-open A file is specified when the default application will be used. Probably the voting configuration (which can be in one of the many cascading override locations within the mimeapps.list file: User-Desktop, User, Sysadmin-Desktop, Sysadmin, Default-Desktop, and Default ).

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
