Good Day!

I'm new to Lazarus and would like to know how I can display a PDF in a Form ...

Thank you!

Also for a simpler example and more up-to date version of the bindings mentioned in that thread:

Can I ask a related question please. Is there an /efficient/ way of opening a PDF at a given section or page+fraction? Area of application is tagging lines of code with references to hardware manuals, some of which might be ancient bitmaps, and at present I'm resigned to pre-processing each PDF into a database of PNG images.

Malcolm,

Reading this thread I went to the link. It seems this is a POS system. Since I'm thinking about writing a POS system myself I downloaded firepos and I tried to compile it. But I'm having dependency problems, fpgui related. I have a development system (odroid arm-linux) that has lazarus 1.1 and fpc 2.7.1 (both some svn downloads). I also have fpgui 1.0. I tried to set the path's to include that fpgui in firepos, or the fpgui in the firepos tree, but both fail because some (different) units are not found.
Could you provide some guide how to setup lazarus to compile firepos ?

Thanks in advance,

Koenraad Lelong

Thank you *very* much Koenraad for mentioning that this project uses fpGUI. I didn't find any docs at the site but I hope to study the code more ASAP. It is very interesting to see a fpGUI program set up for use with a touchscreen! I've started down that path myself.

It seems to be setup to use Lazarus? I didn't think fpGUI support in Lazarus was very complete but maybe things have been improved recently?

Anyway, I hope to add a link to the project to these 2 fpGUI sites: http://www.turbocontrol.com/easyfpgui.htm
http://www.ctrlterm.com/
Those site show how easy it is to compile fpGUI programs.

Paul,

The code is managed with Lazarus, I think. The GUI is made with fpgui-designer or what's it called ?

Koenraad

Koenraad is correct, the module that uses fpgui was designed using the uidesigner application that comes with fpgui. All the other coding was then done using Lazarus.

You'll notice there are no release packages :) This is mainly because I haven't got around to trying to set up the applications on a bare system to work out what is missing and what an installer or install script needs to provide. I think you'll probably need some sample data, as I think some of the SQL queries will fail if they find empty tables. Just warning you that this could be a bit frustrating ;)

Anyway, I suspect that I know what the fpgui problems are. I have modified a few units to provide a little functionality that Graeme appeared to have started on but not completed, and also enable me to have a TPanel with a Borderstyle of bsNone - offhand I can't remember why I needed this but details of all changes (I hope) and all modified units are in the fpgui subdirectory of trunk. They are from fpgui-0.8: I have not yet had time to try fpgui-1.0 and see if they clash with any changes.

If you use fpgui 0.8 and overwrite the modified units with the ones from the FirePos repo I think it will probably compile, although you may need to add a few paths in Project->Options. Only the Sales Terminal module uses fpgui - the others use the LCL. You will need LNetbase for all modules.

It has been developed using Lazarus 1.0 and FPC 2.6.0

I hope you find it useful.
