background colors in ppviewer

rbuser

Hi,

i have a problem running a report in the ppviewer component.

If i run it from the designer it show the colors correctly.
If i run it to show it on the screen from inside the tppviewer component
the colors are black and white.

I alternate font and background color in the detail after generate like
this:

if kleurteller = 1 then
begin
Detail.Background1.brush.color:=rgb(255,255,255);
dbtMedewerkerNaam.Font.color:=greenfontcolor;
end
else
begin
Detail.Background1.brush.color:=greenfontcolor;
dbtMedewerkerNaam.Font.color:=rgb(255,255,255);
kleurteller:=0;
end;

Both the font color and the background color are rendert to black and
white..

i use version 14.06 with delphi xe2

Any help is apreciated!!!

Kind regards

Ruud

Extra information. An image on the same page does keep its colors.

Hi Ruud,

If you would like to alternate the detail band color, I suggest using
the BackgroundColor1 and BackgroundColor2 properties rather than
manually changing the BackgroundColor1 property in the AfterGenerate event.

As for the font color, I suggest using the BeforePrint event of the
detail band to modify the font color. Something like the following...

if (ppReport1.DetailBand.Count mod 2 = 1) then
ppLabel1.Font.Color := clGreen
else
ppLabel1.Font.Color := clBlack;

Hi Nico,

thanks for the quick response

It seems the problem is not in the assigning of the colors to the font
or background.

I use the GlobalOnCreate event to initialize the colorvariables.
If i move that to the AFtergenerate as well everything works fine.

Is the GlobalOnCreate never triggered if a report is run in tppviewer?

Regards Ruud

Hi Ruud,

Thanks for the clarification. For future reference, please let us know
that you are using RAP or post RAP questions in the RAP newsgroup. I
originally thought you were writing your code in Delphi .

When calling PrintToDevices (as you likely are to show the report in the
TppViewer), the InitializeParameters routine is not automatically called
which in turn fires the GlobalOnCreate event in RAP. You will need to
make the call manually if you require this functionality.

if ppReport1.InitializeParameters then
ppReport1.PrintToDevices;

Hi Nico,

thanks for you information.

Actualy i just call loadreport (ppReportExplorer.LoadReport) and then
call the refresh function on the viewer component.

Sorry i did not mention RAP. (I was in kind of a stressfull situation
installing this to run on a big T.v. in a can-tine. A lot of people
commenting on the lack of colors.)

I was lucky to find the work arround and will fixs it in the program
next week.

Regards

Ruud
