Control multiple program instances - open multiple files problem
Hello. This shouldn't be an unusual problem, but I cannot find anything about it at google or at other search machine.
So, I've made an application using C++ and QtCreator. I 've made a new mime type for application's project files.
My system (ubuntu 10.10), when I right click a file and I choose "Open With 'Default Application'" the it runs
Code:
default_application path/to/the/selected/file1
So, if you select multiple files and select "Open With 'Default Application'" the system will call
So, this is a big problem for me, because I handle the concurrent processes from inside the program, so when another instance of the program is running, a warning message is appeared. So, each application's call will recognize the others as currently running applications and so it'll show the message. I'll end up with 3 Messages saying that another process of the program is running --_--'
My application handles multiple URLs this way:
How can I make my code handle all these multiple instances at the same time? Everything I've tried fails, because everything I've tried requires a check from the first instance called, which is too slow and other instances come app and all together are warning about concurrent processes of the same program
So, how can I fix this? is it system depended, or can I do something with the code?

RUN-MAILCAP(1) Run Mailcap Programs RUN-MAILCAP(1)NAME
run-mailcap, view, see, edit, compose, print - execute programs via entries in the mailcap file
SYNOPSIS
run-mailcap --action=ACTION [--option[=value]] [MIME-TYPE:[ENCODING:]]FILE [...]
The see, edit, compose and print versions are just aliases that default to the view, edit, compose, and print actions (respectively).
DESCRIPTION
run-mailcap (or any of its aliases) will use the given action to process each mime-type/file in turn. Each file is specified as its mime-
type, its encoding (e.g. compression), and filename together, separated by colons. If the mime-type is omitted, an attempt to determine
the type is made by trying to match the file's extension with those in the mime.types files. If the encoding is omitted, it will also be
determined from the file's extensions. Currently supported encodings are gzip (.gz), bzip (.bz), bzip2 (.bz2), and compress (.Z). A file-
name of "-" can be used to mean "standard input", but then a mime-type must be specified.
Both the user's files (~/.mailcap; ~/.mime.types) and the system files (/etc/mailcap; /etc/mime.types) are searched in turn for informa-
tion.
EXAMPLES
see picture.jpg
print output.ps.gz
compose text/html:index.htm
extract-mail-attachment msg.txt | see image/tiff:gzip:-
OPTIONS
All options are in the form --<opt>=<value>.
--action=<action>
Performs the specified action on the files. Valid actions are view, cat (uses only "copiousoutput" rules and sends output to STD-
OUT) , compose, composetyped, edit and print. If no action is specified, the action will be determined by how the program was
called.
--debug
Turns on extra information to find out what is happening.
--nopager
Ignores any "copiousoutput" directive and sends output to STDOUT.
--norun
Displays the found command without actually executing it.
