Changing the width of a rectangle inside an event (onbefore print)

[sergiomaster]

Hello,

i'am trying to change the with of a rectangle like this

function rectangle1_onbeforeprint(self: Travecontrol)
var
w : Double;
begin
w := 3.50;
self.width := W;
end;

but , at my (bad) surprize , the result of my width is 3 not 3.5 as
expected . i tried 3.45 , 3.65 etc ...

it seems that Self.width is taking only the fixed part of the number,
but with is an extended no ?

how can i circumvenate this ???

thanks

what is the width at desgintime? Is it 3? So maybe assigning size at runtime
(at least within this event) doesn't work.
If it is not 3 at design time try writing "self.width := 365/100;" in code.
Coding float values this way helped me in many circumstances.

(No at design time it was 5)

thanks for your reply , your tip "self.width := 365/100;" just work fine

Hello SergioMaster,

In general you should always avoid just assigning heights/widths/etc as raw
numbers. Instead you should use the conversion functions e.g. XI2U, YI2U,
etc. This will allow RAVE to make the necessary conversions for you.

Hi sergiomaster,

If w refers to the width. Simply change your code to something like w :=
rp.XI2U( 3.5 );

This will ensure that 3.5 is treated as 3.5 inches.
The 'rp' refers to the TBaseReport component

Hello Trevor,

OP referes to Rave scripting language. XI2U is not available there, is it?

Hello Klaus,

It is available even in the scripting language.
