I'm Having Trouble suppress a frame based on the copyfit of another frame

[sandig@customprinters.com]

I am trying to switch which frame contains copy, based on a copyfit.
If copy fits in Frame A ("textblock"), then Frame B ("textblocklong") is suppressed.
If copy does not fit in Frame A, then Frame A is suppressed and Frame B is used.
Copy will always fit in Frame B.

I cannot figure out to get this rule to put copy into Frame B("textblocklong") only when FrameA !Copyfit

It does manage to suppress frame B when copyfits
It does manage to suppress frame A when !copy does not fit
It does not manage to put content into Frame B when !copy does not fit

This novice needs some help with this rule.

if (FusionPro.Composition.CurrentFlow.name == "textblock")
{
if (!Copyfit(new MagnifyAttributes("text", 100, 100, 0, 0)))
FusionPro.Composition.CurrentFlow.content = "";
}else{

(FusionPro.Composition.CurrentFlow.name == "textblocklong")
FusionPro.Composition.CurrentFlow.content = "";
}

}

In the OnCopyfit callback rule, you can't modify the contents of any text frame, or suppress a frame, other than the one being currently processed.

What you can do, in OnRecordStart, is use the FusionProTextMeasure object to determine whether the text would fit into a particular frame, then set each frame's suppress property, or its text contents, as appropriate. This will work fine as long as the (smaller) frame doesn't wrap its text around any other frames.

Can you help me with that OnRecordStart text Measure rule to suppress the frame? I very novice here and do not know how to write that. How do you write the text measure to determine if copy does not fit in the frame?

var tm = new FusionProTextMeasure;
tm.useTags = true;
tm.CalculateTextExtent(Resource(BCText));
var tmWidth = tm.textWidth;

if (tmWidth > "XX??") //if text exceeds frame
{
FindTextFrame("textblock").suppress = true;
FindTextFrame("textblocklong").suppress = false;
}
else
{
FindTextFrame("textblock").suppress = false;
FindTextFrame("textblocklong").suppress = true;
}

Thanks for your help.

Something like this:

var smallFrame = FindTextFrame("textblock");
var largeFrame = FindTextFrame("textblocklong");

var TM = new FusionProTextMeasure;
TM.maxWidth = smallFrame.GetSettableTextWidth();   
var err = TM.CalculateTextExtent(Resource(BCText).content);
if (err && err != -1)
    throw "Error measuring text: " + TM.messages;
  
var fitsInSmallFrame = TM.textHeight < smallFrame.GetSettableTextHeight();
smallFrame.suppress = !fitsInSmallFrame;
largeFrame.suppress = fitsInSmallFrame;

I just don't know this stuff well enough and I don't know what to do.

I put in your wonderful rule, and it does not seem to understand the text measure. It always uses frame("textblock") and does not use frame("textblocklong") ever. file attached.
