Run QT GUI application on startup - user-interface

I am working on BeagleBone Black(Debian 3.8.13 running on it). I want to run QT GUI application on startup(show GUI on screen just after login).
I am able to run console applications on startup by editing rc.local file in /etc/ directory and placing executable in /bin/ directory. But it didn't work for GUI applications.
I have searched for it also but couldn't make much out of it.
I want to know how it is to be done.

How to build an installer for a python application for Mac

I have created a python application and can install it perfectly fine on Windows. I run pyinstaller to generate the executable, and then use NSIS to create an actual installer. I run the installer and it installs the application to my Program Files folder and gives me a nice desktop shortcut, etc.
What is the process to do the same for Mac? Essentially, I want to give my user a single file. When they run the file, it installs my program and any necessary libraries, and let's them launch it with a single click. I believe on Mac this is done with a .dmg or a .pkg file. What software/tools do I need to generate such a file? Do I need to restructure the project in anyway to create this?
For more info, pyinstaller creates a folder 'dist' which contains the unix executable of the application, and copies of python and any required libraries.
Note that I do not want to use the onefile option for pyinstaller because it would take a while to unpack everything each time the program is ran.

macos OS X equivalent of Linux .desktop file

I have developed a set of shell scripts that work on Windows and Linux and would like to distribute them for macos 10.4 and following. (They are to help language development workers in minority languages keep their software up-to-date. You can read about the project at lingtransoft LangTran.)
I make the Windows installer with Inno Setup and the .deb file for Linux with EPM. I have been able to make a .pkg installer by running EPM on a Mac, and it installs the shell scripts to the right place, and they work properly when I run them from a Terminal window, but I would like to provide clickable icons. If I can work out the macos/OS X equivalent of a Linux .desktop file, I should be able to get the EPM package maker to install the launcher files in the right place.
For Linux, EPM will package my hand-crafted .desktop files and install them in the right place for them to appear in the menu. (Here is one of the .desktop files:
[Desktop Entry]
Name=LangTranUpdate
X-GNOME-FullName=LangTran Update Script
GenericName=Software Distribution System updater
Comment=For updating a local software repository
Path=/usr/local/langtran
Exec=/usr/local/langtran/LangTranUpdate.sh
Icon=/usr/local/langtran/Progs/LangTran-icon.ico
Terminal=true
Type=Application
Categories=Network
StartupWMClass=gpodder
)
The script needs to run in the folder /usr/local/langtran because it looks for other files in the same place, so the "Path" key is set to that. The Windows shortcut files work the same way.
Since macos doesn't have a START button to open a menu tree, I would like the installer to put clickable objects on the desktop so the user can drag them to the Dock if desired.
So my question is: How do I make the macos/OSX equivalent of a Linux .desktop file or a Windows shortcut?

run executable in current directory mac

I write an GUI application in QT running in MAC SIERRA OS the work of this GUI is to execute some scripts and edit some that are located in the directory that the app exists!!
When i run the app from the QT IDE environment the app finds all the scripts and files which are included in the directory and it works as it has to work!
If now I try to run the app just double clicking it in the file explorer(finder in Mac) then the app can't find any script and file that need to find!!
The reason is that when I double click in the app the app is executed always in the "/" directory or in "Users/username" directory and IT IS NOT executed in the directory that it exists!!
Is there some way to change that behavior in this OS???
P.S:the same code works excellent in UBUNTU OS

Mac OS install application and run a script on startup

I'm looking for a way to package my application with the added requirement that I need to add a python script to always run on startup.
What I've been trying so far is having a .pkg that installs the .app into the applications folder and adds the python script (wrapped in a .plist launch daemon) to the user's LaunchAgents folder.
I've tried a lot of different things, but for whatever reason the python script runs fine on the command line and just doesn't work when running through launchctrl. I could go into what the problems were, but I feel that would make more sense as a separate question.
I am wondering if I should be using a different approach to achieve my goal of installing the app in Applications and having a python script run on boot. Is there a more standard solution that I am missing perhaps? Thanks.

Cocoa application won't run because Contents/MacOS/Application is not a Unix Executable

My application runs fine on my system, and also on several others.
However, some people can't run the application because the file in /Contents/MacOS/ApplicationName is not a Unix executable file.
Inputting the following line in the terminal forces the application to be executable, and solves the problem:
chmod +x ApplicationName
Obviously this is a very hacky way around the problem, and I don't want to tell users to enter chmod to run my application. What am I doing wrong? Why is it appearing as a Unix executable file on some systems, but not others? It could be a permissions issue...
at the moment, i transfer the app via dropbox to a client
Dropbox has problems with OS X metadata and permissions. Archive the application first (from the Finder context menu) and put the zip file into Dropbox.
