How to detect overflowed text?

Report · Sep 18, 2008

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\n", 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,
