How to detect overflowed text?

Question

Hello,

I'd like to programatically detect overflowed text (ie. text which is not visible in its entirety). In reference guide I found that it should work be obtaining FP_Overflowed property of FO_SubCol, but it doesn't work for me. Here's sample document:

How can I detect it properly?

Thank you.

Hi Stanislav...I've used the following code to detect an overflow .. F_ObjHandleT pageId = F_ApiGetId(FV_SessionId, docId, FP_FirstBodyPageInDoc); while (pageId) { F_ObjHandleT pageFrameId = F_ApiGetId(docId, pageId, FP_PageFrame); F_ObjHandleT frameId = F_ApiGetId(docId, pageFrameId, FP_FirstGraphicInFrame); F_ObjHandleT subcolId = F_ApiGetId(docId, frameId, FP_LastSubCol); F_Printf(NULL, "pageFrameId %d; frameId %d; subcolId %d
", pageFrameId, frameId, subcolId); if (F_ApiGetInt(docId, subcolId, FP_Overflowed) == True) { // do something } pageId = F_ApiGetId(docId, pageId, FP_PageNext); }When I run this on your file, it appears that your small overflowed textframe has no subcols, thus no place to check for the FP_Overflowed property. I'm not sure exactly why there would be no subcols (an Esc,g,o shows that it has one column .. ??).Good luck,...scott
