- (Hash) ParseSingleDesktopFile(file)

Parses the a .desktop file it gets as a parameter without trying to use already cached information or agent to access all desktop files. This is optimized version to be used for rapid start of modules. Desktop file is placed in a special directory (/usr/share/applications/YaST2). Parameter file is relative to that directory without “.desktop” suffix. Warning: There are no desktop files in inst-sys.

// Opens /usr/share/applications/YaST2/lan.desktop map<string,string> description = Desktop::ParseSingleDesktopFile (“lan”); Wizard::SetDialogTitle (description:_(“None));

Parameters:

  • file (String)

    desktop file name

Returns:

  • (Hash)

    filled with data, or nil
