ConfigFrame, An easy way for to create Config Dialogs

[Edson]

I was tired of to write repetitive code, when writing configuration dialogs for move values from:

Control <-> Variable <-> INI File

So, I decided to create my own TFrame, for config Dialogs.

The idea was to have a TFrame class, with new methods, that make it easy to modify some variables of the App, and be able to save(restore) them to disk.

I thing this could be useful, so I share it:  https://github.com/t-edson/ConfigFrame

Edson, thanks for contributing such a useful ini-based configuration framework.

BTW who is Tito Hinostroza (I presume the spelling Tito Hinojoza in some comments is the same person)?

[Edson]

Well, I was looking for some code to do this work, but finally I decided to write the mine. I decided INI files because they are simple. I hope I'm not reinventing the wheel.

About the name, I am Tito Hinostroza (not Hinojosa). I use to sign with my name and last name on my code and docs.

You should consider using the TIControls because from my point of view the whole point is not to link a control to a config file but the data to the ini file. I'd rather see a Frame which auto-creates some TIControl according to its published props. But that's a point of view to think that the GUI just represents the data. Nice try anyway.

RTTI Controls, looks a good choice (just for linking properties to controls), but I've had problems working with them. I will investigate more. Thanks for the advice.

One of the objectives for of my work, was to easily read/write variables from/to disk. Even if these properties are not going to be visible, (associated to a control).

That's why I have included these methods:

Asoc_Int(ptrInt: pointer; etiq: string; defVal: integer);
Asoc_Bol(ptrBol: pointer; etiq: string; defVal: boolean);
Asoc_Str(ptrStr: pointer; etiq: string; defVal: string);
Asoc_StrList(ptrStrList: pointer; etiq: string);

They just register a variable for to be saved or read from disk. After register many variables, they are all saved to disk with a simple call to SavePropToFile().  The ini file is automatically created if it doesn't exist.

Moreover, this rutines included some range validation (for integers), and a default value, for the first time, they are read from disk.

ConfigFrame 0.3 released:

https://github.com/t-edson/ConfigFrame

It was improved the work with strings, and have been added associations for new controls.

ConfigFrame 0.4 released.

Improved the capture of errors on Config frames, and a new method added for to associate variables to TRadioGroup controls.

This library can solve the problem shown here:

Hello Edson!

Very useful unit. Thank you for sharing.

[Edson]

Hi Roland. You're welcome.

Like others of my libraries, this was the product of a necessity, when I was developing some Apps. I think it could be useful, that's why I shared it. Soon I will be publishing a project that use this unit.

I just have tested it on Windows, so I don't know if it's functional on Linux o Mac.

ConfigFrame 0.6 released.

Updated until Lazarus 1.4.2.
Now ConfigFrame it's a real Frame instead of a simple unit, like in previous versions.
