How to mark overflow

[ba77269862]

Hey,

I'd like to have a script that goes through the document and places a string in each paragraph or table that has overflow. Any ideas how I can achieve this?

Thanks.

Tables (Tbl) and Columns (SubCol) objects have an Overflowed property that will tell you if they are overflowed. I am not sure how to identify which paragraphs are actually overflowed, but it may involve seeing if their Y location is greater than the subcolumn (or text frame) height.

Thanks for the reply!

I've played around with this for a few hours now, I now feel like I asked the wrong question to begin with.

Instead of overflow, I think I need to determine whether pagination occurs. Say I have a table with 5 rows, 2 on one page and 3 on another; I'd like to place a marker after the 2nd row. I will then use that marker when publishing to HTML.

I was thinking of looping through all rows in all tables, and then comparing the pages of the rows of the same table to figure this out, but I can't seem to get page information from a row (or cell)

Afterwards, I will have to figure out a way to do this for paragraphs, but one step at a time...

Here is a general-purpose function for getting parent Page for an object. Once you get the Page object, you can test its Page.PageNum property.

function getPage (obj,doc) {
    var frame = 0, cell = 0;
    var objType = "", prop = 0;
    while (obj) {
        frame = obj;
        objType = obj.constructor.name;
        switch (objType) {
            case "SubCol" :
                obj = obj.ParentTextFrame;
                break;
            case "Tbl" :
                obj = obj.FirstRowInTbl.FirstCellInRow;
                break;
            case "Row" :
                obj = obj.FirstCellInRow;
                break;
            case "Cell" :
            case "Pgf" :
            case "AFrame" :
                obj = obj.InTextFrame;
                break;
            case "TextLine" :
            case "TextFrame" :
            case "UnanchoredFrame" :
            case "Arc" :
            case "Ellipse" :
            case "Group" :
            case "Inset" :
            case "Line" :
            case "Math" :
            case "Polygon" :
            case "Polyline" :
            case "Rectangle" :
            case "RoundRect" :
                if (obj.FrameParent.ObjectValid()) {
                    obj = obj.FrameParent;
                } else {
                    obj = 0;
                }
                break;
            case "XRef" :
                prop = doc.GetTextPropVal (obj.TextRange.beg, Constants.FP_InTextObj);
                var obj = prop.propVal.obj;
                break;            
            default:
                // Prevent endless loop if unknown object type is found.
                obj = 0;
                break;
        }
    }
    if (frame) {
        return frame.PageFramePage;
    } else {
        return 0;
    }
}
