CalendarPane lib_Rect commands/functions

Hello, I am sure I am missing something, but I can't get these functions or commands to work on the CalendarPane that I created. Thanks for any help.

Code: Select all
dispatch function "rt_Height( theRect )" to group "CalendarPane"
dispatch "rt_MoveTo @theRect" to group "CalendarPane" with "150", "118"
It says "unhandled" which means no matching handlers were found. I tried putting the function/commands in multiple locations in my stack as well.
Here is the excerpt from lib_Rect stack:
lib_Rect v.09
By David Beck
INSTRUCTIONS FOR USE
Make sure to add lib_Rect to your project and to execute the command:
start using stack "lib_Rect"
The you can use the following functions and commands:
rt_Left( theRect ) -- return left side of theRect
rt_Top( theRect ) -- return top side of theRect
rt_Right( theRect ) -- return right side of theRect
rt_Bottom( theRect ) -- return bottom side of theRect
rt_Width( theRect ) -- return width of theRect
rt_Height( theRect ) -- return height of theRect
rt_Make( theLeft, theTop, theRight, theBottom ) -- return "theLeft,theTop,theRight,theBottom"
rt_IsValid( theRect ) -- return true iff the rect has a non-negative width and height
rt_MoveTo @theRect, newLeft, newTop -- move theRect to newLeft, newTop
rt_Offset @theRect, deltaX, deltaY -- offset theRect by deltaX, deltaY
rt_Grow @theRect, growBy
rt_Intersection( rectA, rectB )
rt_Union( rectA, rectB )
rt_AlignAToB @rectA, rectB, direction -- align the center of rectA to the center of rectB
rt_AWouldFitInB( rectA, rectB )
rt_MoveAToBeWithinB @rectA, rectB

First off, if you "start using" lib_Rect then dispatching functions and commands to a group won't work because they aren't in the group.
Try
Code: Select all
dispatch function "rt_Height" with theRect
although you then have to decide what to do with the returned value
and
Code: Select all
dispatch "rt_MoveTo" with @theRect, 150, 118
However, since the functions you want to use are already in a library in use, I don't see an advantage in using dispatch:
Code: Select all
get rt_Height(theRect)
rt_MoveTo @theRect, 150, 118
should do the trick for you.

Thanks for helping mwieder. I did try as you suggested and got an error:
stack "testCalendar": execution error at line 30 (Operators -: error in right operand), char 1
from this function:
Code: Select all
function rt_Width theRect
return item 3 of theRect - item 1 of theRect
end rt_Width
Not sure what might be occurring.

What is the value of -> theRect in your script?

Hey Klaus, it is giving me the value of "theRect" which seems to be the issue I imagine.
On startup I do:
Code: Select all
start using stack "lib_Rect"
start using stack "lib_CalendarPane"
Thanks for any help

You know that you need to supply a VALID rect (= 4 numbers separated by COMMA)?

Thank you for replying. I thought the value of the Rect was supplied by the calendar pane stacks. I will try to study this further when I have time.
