Re: Access current row/columns cells

The "Sender" parameter in the OnClickedHeader event is the column that is under the mouse xy position, you can use it to determine the column index, name etc. For example: procedure TFormGridCharts.TeeGrid1ClickedHeader(Sender: TObject); begin Caption:=Sender.ClassName; if Sender is TColumn then Cap...

There is already an example using Master-detail datasets (not TeeBI) :

Re: Form42 Example

Hi oflor Automatic embedded "live" charts inside grid cells is planned for next release (v1.5 maybe).

Re: C++ Faults when a TChartListBox is used in a DLL.

I've just tested the project with "XE5 Update 2" and it works fine, the AV exception does not raise. Attached the project opened and saved with "XE5 Update 2". I've added Dependency from Exe to DLL so the IDE will recompile both projects when changing something in the DLL project. I've added another...

Re: C++ Faults when a TChartListBox is used in a DLL.

I've submitted a new issue to our bugs database to keep this problem alive:

http://bugs.teechart.net/show_bug.cgi?id=522

Still can't identify the exact cause. I'd like to try to reproduce the problem without using any TChart module, just using the GDI+ units to check if the problem is there.

Re: Drawing bitmap on Windows

There are several usages of ScanLine already in FireMonkey TTeeCanvas, of course. I've changed the example using scanline, same (ok) results, see below. TeeCanvas StretchDraw simply passes the bitmap to FireMonkey's DrawBitmap method, there is nothing changed: procedure TTeeCanvas3D.StretchDraw(cons...

Re: Can I only export active series to a text file.

A new property in TSeriesData class has been introduced to allow exporting only a selected list of Series. http://bugs.teechart.net/show_bug.cgi?id=243 This wish has been implemented, at the base class TSeriesData (TeeStore.pas unit), so all derived export format classes now have a new property (an ...

Hi Atmapuri

Just did the attached test project and it looks fine to me (both with high and low stretch blending modes).

Re: C++ Faults when a TChartListBox is used in a DLL.

I've been doing more testing. I think I got it to work, but the solution is not yet clear to me. What I did was to include the Delphi units to the exe project (VCLTee.Chart, VCLTee.TeeProcs, VCLTee.TeEngine) and then build it. What might happen I guess is the units get compiled to *.obj in a differe...

Re: C++ Faults when a TChartListBox is used in a DLL.

>>It appears that you have some type of code that is either new or left over that deals specifically with a DLL file. You're right. I was wrong. It happens the TChartListBox unit uses other units that in the end they are using the GDIPAPI. Yes, I can reproduce the exception with your test case. I'm ...

Re: C++ Faults when a TChartListBox is used in a DLL.

There's one thing you can try just to see if the exception is not raised. First, set any chart to *not* use GDI+ canvas (chart editor dialog -> 3D -> Render -> GDI) Then, change this registry value to be an empty blank string: HKEY_CURRENT_USER\Software\Steema Software\TeeChart Pro\Editor -> Default...
