TeeChart Pro beta for Lazarus 1.0.10 LCL

Full sources included.

This beta version compiles fine with Lazarus 1.0.10 (teechart.lpk package, in "Delphi" mode), and can be  also installed in the ide for design-time support. (Uninstalling TAChart package to avoid class name conflicts).

Some important bugs are present, specially at the design-time/runtime editor dialogs, that I hope to fix soon but I'm stuck on some issues that work fine with VCL.

Thanks - good to see more support for Lazarus!

Thanks for making this package available. What's the license for using?

Initially, I failed to install teechart.lpk into Laz 1.0.10 / fpc 2.6.2 and into Laz-trunk / fpc 2.6.2, both Win32. The compiler complains in function NumberOfProcessors, unit TeeClustering, about PAfficinity being a QWORD, but expecting a LongWord. After changing this, the package compiles and runs fine.

Code: [Select]

function NumberOfProcessors:Integer;
{$IFDEF MSWINDOWS}
var t : Integer;
    PAffinity,
//    SAffinity: {$IFDEF D16}NativeUInt{$ELSE}{$IFDEF LCL}QWORD{$ELSE}DWORD{$ENDIF}{$ENDIF};
    SAffinity: {$IFDEF D16}NativeUInt{$ELSE}{$IFDEF LCL}LongWord{$ELSE}DWORD{$ENDIF}{$ENDIF};
    {$IFNDEF D16}

Thanks for the fix !

I've added an ifdef to make it compatible with both 64 and 32 bits:

{$IFDEF CPU64}QWORD{$ELSE}LongWord{$ENDIF}

I'll add a "License.txt" file in next coming beta builds, with a similar text than:

People contributing as beta-testers will get free licenses for the final release version.
(email me at david@steema.com if you wish access to the beta forums at our web site)

If under IFDEF, simply write PTRUINT. More recent FPC versions (iirc 2.4.2+) also add the Delphi NativeUint alias to the native ptruint though.

Uninstalling TAChart package to avoid class name conflicts

To the architects of Lazarus and FPC: Why is this necessary? In my opinion, the IDE has all information to distinguish between the TChart from the teechart and the TChart from the TAChart package.

Afaik only one can be registered for streaming.

Is there a fundamental reason for that? Would it be possible to use a fully qualified name, like, e.g., chart.TChart.pas (for TeeChart) and tagraph.TChart (for TAChart)?

[teechart]

The problem are lfm forms. If there is a "TChart" component inside an lfm, the IDE cannot guess which one is it (if both were installed at the component palette at the same time).

It could do the guess by parsing the pas "uses" clause before loading the form, though.

Delphi compatibility. Moreover, only since D2010 you can get the unit a class is in afaik. Before that there was only .ClassName()

Would it be possible to use a fully qualified name, like, e.g., chart.TChart.pas (for TeeChart) and tagraph.TChart (for TAChart)?

Not short term, and it would be incompatible.

New update uploaded, compatible with 1.0.12
 Still some errors at editor dialogs, some have been fixed
Runtime functionality is quite good.

I don't find any link

Your link says that the beta test has finished; therefore I suppose that the component is only available to registered users again.
