The implementation is up to you. But I do not want to change the steema units every time I (or my colleague) installed a newer version.

Is it planned to make the checkbox more convenient?

Thank you for the fix. It works for the last line. But unfortunately the header lines are now shifted slightly right.
You can see this with my example program.

Here is my example:

I used this example to colorize the header, but now unfortunately the header lines of the last visible column (left and right) are not drawn:

To make it working I did the following points (if somebody is interested): TFMXTeeGrid.TryChangeEditorData function GetEditorText if IEditor is TCheckBox then begin if TCheckBox(IEditor).IsChecked then result:='True' else result:='False'; end Draw a hook (not a cross) in TShapePainter.Check Assign T...

Is there any way to set the grid horizontal scrollbar height?

Thank you, now it is working

I changed the code as you suggested. But the method isn't used by the example program. Do I have to change anything else?

Here is my example.

The effect isn't visible with your example. But with modification to LineSeries I got the issue:

I have a TeeChart at one panel and a TeeGrid at another panel. If the chart has a legend with shadow, the grid column headers are drawn with shadow color background! There should not be a connection.

Thank you for the code, it works fine!

Hello, is it possible to draw the crossing points of the axes grid lines only?

In TSeriesPointer.DrawPointer case psSmallDot Pixels[PX,PY] is filled with Brush.Color. This isn't sufficient for FMX -> nothing is drawn.
