[Lazarus] GUI frontend to a console application
Hi, This is probably more related to unix systems... Has anybody got a small sample application, some documentation or is a sample included in Lazarus that shows how to go about writing a GUI frontend to a console application? For our company I want to implement a GUI app to help them setup a few basic things on a Linux system and interact with some console apps. Our users are NOT tech-savy, so I need a GUI to help them along. Any idea how I go about this?

What then is your technical problem? For example, Linux has many GUI frontends for programs like makeiso, burncd, cdrecord, cvs, mpg123 etc... These frontends most probably collect the options and then call the backends with the appropriate command line. Or they use the application libraries directly, without starting the console programs. In this case the command line argument evaluation has to be moved to the GUI frontend, which finally calls the same procedures as the main procedure of the console application does. For easy maintenance the console programs can be changed to use a shared library, which then can be used by every frontend. The shared libraries then should not do any console output, eventually output to stdout or stderr must be caught by the frontend, or the handles must be redirected/piped to the frontend. I never separated existing applications into shared libraries, so I don't know about the best solution for console output. When every output ends up in a few unique procedures, these procedures can be replaced by callback functions, provided by the frontend and installed during initialization of the shared library.

Add a TSimpleIPCClient to your console app, so that it can send message to its paired up TSimpleIPCServer which is hosted on the GUI frontend. This way, your console app can speak to your GUI frontend app. Be sure to read an argument as your IPCServerName, so it knows which IPCServer to talk to. On your GUI frontend, use a thread to read messages from the IPCServer continuously. If you want to execute multiple console apps simultaneously, use TProcess to execute your console apps with poWaiting and poUsePipes turned off (so that it returns control to your app immediately) and use a TSimpleIPCServer to listen to the TSimpleIPCClient from your console app. In the long run you should have a multi-threaded process-manager that handles a collection of TProcess and TSimpleIPCServer. I have chopped up all my big apps into small console apps and frontends. So, my apps can all run with or without a GUI. So my big app is now a package of console apps and a frontend, sort of like how Linux works. A rough model of my process-manager: ** TIPCServerThread = class (TThread) public IPCServer: TSimpleIPCServer;//For listening to the IPCClient of the console app end; TIPCProcess = class (TCollectionItem) public Process: TProcess;//For executing the console app (Execute without waiting) IPCServerThread: TIPCServerThread;//Listens and update status of this process property Status; property Progress; property MaxProgress; property Errors; //Note: the console app will receive an IPCServerName as a argument so it knows // which IPCServer to talk to. end; TIPCProcessList = class (TCollection)//For handling a collection of TIPCProcess. TIPCProcessManager = class(TComponent) //For complex mangement of processes like executing events when a particular process completes. //or a timer for polling the processlist for status to be displayed or actions to be taken. ** This allows me to add features to my app easier as debugging my new console app is easier than debugging the monolithic app (most of my console apps handles long-loopy functions). Also you take advantage of multi-core processors instantly as the OS will do it for you like as though you open multiple programs, you don't need to spend time tweaking your threads to consume or force-feed them to a paticular core.
