Missing reference to TeeChartControl and inheritance bug

rbuser

Settings:

Delphi 7, ReportBuilder 10.04, TeeChart5.03
----------------------------------------------------------------------------

I?m facing two problems after migrating from Delphi4-ReportBuilder5
To Delphi7-ReportBuilder10.04

The first strange behaviour appears when I drop a TeeChart component on my
ppReport.

If i open the ParentForm.dfm file, i can see that ppReport1, ppTeeChart1 and
ppTeeChartControl1 has been added to the form. Everything seems normal.
[ParentForm.dfm
object ppReport1: TppReport
object ppTeeChart1: TppTeeChart
object ppTeeChartControl1: TppTeeChartControl
end
end
end
]

But now, if I take a look at the ParentForm.pas file i surprisingly see
that there is no reference to the ppTeeChartControl1 object.
[ParentForm.pas
ppReport1: TppReport;
ppTeeChart1: TppTeeChart;
]

The question is:? Why is there no reference to ppTeeChartControl1 object
in the ParentForm.pas whereas it exists in the dfm" ?


This first problem triggers a second one when I try to inherit a ChildForm
from the above ParentForm.

If a try to do this, I can see in the ChildForm.dfm that both ppTeeChart1
and ppTeeChartControl1 exists (see below), but when I try to save this
ChildForm after a color modification in the ppTeeChartControl1 , Delphi
Claims that ppTeeChartControl1 was not found in the ancestor class.

inherited ppReport1: TppReport
inherited ppTeeChart1: TppTeeChart
inherited ppTeeChartControl1: TppTeeChartControl
Color = 16744703
end
end
end


Note that these two cases worked fines with ReportBuilder5 !


Any Help would be very appreciated,
B.

Hi Bruno,

This was a change we made a while back to better manage the TChart object
from the TppTeeChart. In order to change the color of the chart, you will
need to access the TppTeeChart.Chart property at runtime.

Hi Nico,

Thanks for your reply.

I understand how to access the chart properties in the parent form.
But i still have a problem with the childforms (derived forms). My
application is based on form inheritance, and delphi doesn't want to save
these childforms even if i don't change anything to the chart properties.

Hi Bruno,

I'm very sorry for the delay, my newsreader did not pick up you last post.
If possible, please send a minimal example of what you are trying to do
(including the form inheritance) in .zip format to
support@digital-metaphors.com and we will try to find a workaround/option
for you.
