Accessing LazReport Components by code

[essence-ciel]

Hello,
Sorry for my bad English. I'm not familiar with the forums, excuse me too.

I'm trying to access frReport (LazReport) components programmatically from a Lazarus form (Settings form).

In order to find the components, I used this code:

Code: Pascal  [Select][+][-]

1. for I := 0 to frReport1.ComponentCount -1 do
2.       if (frReport1.Components[I] is TGroupHeader) then
3.             frReport1.GroupHeader1.Visible := CheckBox3.Checked;

     

But it's impossible to display/hide the frReport GroupHeader. Ditto for changing the color of the associated Memo.

How can I retrieve the component and modify it by code, please?

Windows 11, Lazarus 3.4, Sqlite 3.46.1

You can solve this in several ways:
1. use parameters that can be used in the script for each band / memo
2. use the events OnBeginBand (for the band) and OnEnterRect (for the memo)
3. create reports dynamically using the lrCodeReport component - an example can be found in the directory: "{LazarusDir}\components\lazreport\source\addons\lrcodereport\sample\"   
 
The first two points are in the attached example

Hi,
Thanks a lot. I'll study code and apply it.
Best regards,
