I am an old goat for what concerns Delphi, but I am an abolute beginner re FPC.

One simple question:

is there around any (free or commercial) grid component like TProfGrid (www.profgrid.com) for FPC ?

Or (still better) which chances are that the code of TProfGrid would compile with FPC ?

Thank you

Duilio Foschi

Or (still better) which chances are that the code of TProfGrid would compile with FPC ?

chances are very high, since FPC supports delphi dialect
{$ifdef fpc}{$mode delphi}{$h+}{$endif}

you also need to learn about LCL (Lazarus analog of delphi VCL library) and Lazarus itself.

just start from this wiki page: http://wiki.lazarus.freepascal.org/

No, chances are very low. It's a component which will most-probably depend on several vcl-internals with which the FCL is incompatible. Because the FCL has to deal with several widgetsets and OS'es. While Delphi's vcl is windows-only.

Chances depend on how component is actually implemented. I guess it's very bad practise to make any component to be hardly bound to vcl-internal. It's risky, because vcl-intercals can change (and did change) from one version delphi to another.

I've had to port a couple of components myself, it was not too hard.

If component is windows dependant, then LCL provides replacment for most common WinAPI functions.

Dmitry,

what is LCL ?

A research in the net brought 'Le Crédit Lyonnais', but I doubt that this is the correct anser :)

Thank you

LCL stands for Lazarus Component Library, see this page for more details http://wiki.lazarus.freepascal.org/Lazarus_Documentation

If you want to create a delphi-like visual component, it's very probable, that you're going to use LCL and Lazarus IDE. lazarus.freepascal.org

Thanks,
Dmitry

wow! There is a whole world to explore !

Thank you

:-) And it doesn't stop there... you even have a choice of GUI toolkits you can use with Free Pascal. LCL is not the only one, there are custom written toolkits as well - all implemented in Object Pascal.

Hi

I have had a good time with FoxLib Gui, calling from Ruby. Why is that there isnt an integration of Fox in Lazarus/Fpc ?

I don't know FoxLib. Is that a custom drawn toolkit or a wrapper for other toolkits like GTK, Win32 etc? If it's the latter, then Lazarus LCL already talks (wraps) the main GUI toolkits like Qt, GTK1 & GTK2, Win32 etc... Lazarus doesn't need a wrapper for a wrapper toolkit (hence the reason wxWidgets is not supported).

Custom drawn with a Windows 2000 look on all platforms.

Because no-one has made a widgetset based on it. This is also the first request ever.

Given that it is written in C++ - and that is always a pain - this will not be an easy task either.

Hi

Well, I don't think its a wrapper because i did use it without gtk installed.

Plz have a look at http://www.fox-toolkit.org/.

Do you have a link to FoxLib? A quick google search did not reveal a obvious choice.

As for the Windows 2000 look. I am planning on implementing the LCL-fpGUI widgetset during 2009. fpGUI will have a built-in Win2000 look (including a few others), so hopefully that will fill that requirement. ;-)

I'm always interested in other custom drawn toolkits. It's normally a great inspiration for features I can possibly add to fpGUI Toolkit.

You mean its just another one out there?

I have used the Ruby wrappers of this called FxRuby on Arm-linux boards. Aint crashed or given a problem. But the calender widget was missing till Foxlib 1.6. Otherwise neat stuff.

C++ ought to be good aint it? Even Firefox RDBMS was written in C++?

Thanks for the link, I'll take a look. As Michael said, we haven't seen anybody request support for Fox Toolkit in Lazarus yet.

Could you please check ?

I restarted the firewall. Please try again. I've had other users connect to the news server this morning (web and nntp interface), so it should work. I can access it from our company network as well.

Oops! I meant Firebird RDBMS, not Firefox!

Yes, but the interface API is accessible in plain C.

It would be suicide for Firebird to change that to C++.
