More about variables

rbuser

Hi, i have a variable in the summary band of a report, i also have one
in the group footer.
When is the OnCalc event triggered? If i trace the application this
event is fired a lot of times.
How does it exactly works?
thanks

The goal of the Variable is that you can use it to perform calculations
and not have to know how RB is internally handling things.

However, if you want to know more about the events you can check out the
Events section of the RBuilder\Demos\Reports\Demo.dpr project. You can
use the same techniques shown in the example in your own reports.
Another technique would be to modify your Delphi library path from
RBuilder\Lib to RBuilder\Source, compile your project with debug info.
Put a break in your OnCalc code and then check the call stack....
