The object model for the C1Report component
is largely based on the Microsoft Access model, except that Access has different
types of controls (label control, textbox control, line control, and so on),
while C1Report
has a single Field object
with properties that can make it look like a label, textbox, line, picture,
subreport, and so on.
The following table lists all objects, along with their
main properties and methods (note that C1Report uses
twips for all measurements. One twip is 1/20 point, so 72 points =
1440 twips = 1 inch):
