Not correct CellColNum in FirstCell of SubCol

  • August 2, 2012

Hello everybody,

I try to find out in which column of a table my grafic is placed. I like to adjust each column width depending on the grafic and document size.

The code example at the end of this post just displays my problem.

The script is:

- parsing through all grafics

- checking if FrameParent is FO_SubCol

- putting the FirstCell of the SubCol in an object

- calculates the new widths of the column (the example does not include the whole code)

- using the Cell.CellColNum to find the index (vcounter) for the column width in Tbl.TblColWidths

- setting the new TblColWidths

The problem:

vcounter is always=0, although the grafic is in the second or third column

I expected

0 for column 1

1 for column 2

2 for column 3

Where is my misunderstandig of the  SubCol, Cell objects?

Best Regards

hetshjd

var vGraphic =app.ActiveDoc.FirstGraphicInDoc;

while(vGraphic.ObjectValid()){   

      vTextLocObj = new TextLoc (vGraphic.FrameParent , 0);

     if(vTextLocObj.obj.InTextObj!=null){

           if(vTextLocObj.obj.InTextObj.type==Constants.FO_SubCol)

           {          

              vSubCol= vTextLocObj.obj.InTextObj;

             vCell=vSubCol.FirstCell;

              vTbl=vCell.CellRow.RowTbl;

              if(vTbl.TblNumCols<=1){

                  vColWidth=55* docobj.ViewDisplayUnits;

              }      

              else{

                 vColWidth=(130/vTbl.TblNumCols) * docobj.ViewDisplayUnits;                 

              }

            vCounter=vCell.CellColNum;

            vWidths=vTbl.TblColWidths;

            vWidths[vCounter]=vColWidth;

            vTbl.TblColWidths=vWidths;

            }

       }

   vGraphic =vGraphic.NextGraphicInDoc;

}

Hi Russ, Hi Rick,

thanks for your replies. A lot of strange things with this cell and SubCol object in ExtendScript.

I also recognize "if the table has a title, the oCell object will actually be the "cell" containing the table title".

Also if the graphic is in the second column, the oCell contains the table title of the first column.

Rick, regarding to your suggestions:

- if I navigate through the table cells, I have first to figure out, if there is a grafic in the cell to resize, then resize the grafic and then resize the column.

I like the grafic approach, because its shorter, but for this I have to know in which column the grafic is in.

- if I navigate to the grafics and get only the cell object (without the SubCol), I'll not know which column of the table I have to resize

I did it in Framesript and it works.

Loop While(vGraphic)

   If vGraphic.ObjectName ='Inset'

     

      Set vTextLocObj = vGraphic.FrameParent.TextLoc;

         If vTextLocObj.InTextObj.ObjectName = 'Cell'

            Set vTbl = vTextLocObj.InTextObj.CellTbl;

            Set vTblWidth = vTbl.TblWidth;

            If vTbl.TblNumCols<=1

                 vColWidth=55* ActiveDoc.ViewDisplayUnits;

               Else

                 vColWidth=(130/vTbl.TblNumCols) * ActiveDoc.ViewDisplayUnits);                 

            endif

 

           

            Set vCounter=(vTextLocObj.InTextObj.CellColNum)+1;

            Set vWidths=vTbl.TblColWidths;

            Replace Member Number(vCounter) In(vWidths) With(vColWidth);

            Set vTbl.TblColWidths=vWidths;

 

        

         endif     

   endif

   Set vGraphic =vGraphic.NextGraphicInDoc;

endloop

I'll try the find a solution with the "navigate through the table cells" approch. But it would be nice if there is a solution for the "navigate through the graphic approach")

Hi bjoern,

If you want to iterate based on graphics, perhaps you might consider a different approach that doesn't involve the FirstCell property. I think that the CellColNum property is OK... it's the FirstCell property that isn't working or we just don't understand how it works.

Here is a little function I ran to verify that CellColNum does work OK, as long as the cell object is valid. I don't know if this methodology will work in your case, but perhaps it will give you some ideas.

function graphicTableTest()

{

    var doc = app.ActiveDoc;

    var graphic = doc.FirstGraphicInDoc;

   

    //iterate through all the graphics in the doc

    while(typeof(graphic)!="undefined")

    {

        //for this test, we only care about imported files

        if(graphic.type == Constants.FO_Inset)

        {

            //get the frame parent. If it's an anchored frame, then we want to

            //find out if it's in a table cell or not.

            var aframe = graphic.FrameParent;

           

            if(aframe.type == Constants.FO_AFrame)

            {

                //get the InTextObj of the paragraph that contains the frame anchor

                var subcol = aframe.TextLoc.obj.InTextObj;

               

                //if it is a table cell, report the column

                if(subcol.type == Constants.FO_Cell)

                {

                    alert("Graphic '" + graphic.InsetFile + "' is in a table, column " + subcol.CellColNum);

                }

                //otherwise, just report

                else

                {

                    alert("Graphic '" + graphic.InsetFile + "' is not in a table");

                }

            }

        }

        graphic = graphic.NextGraphicInDoc;

    }

}

Hi hetshjd,

I got to messing around with this and I'm just as confused as you are. The FirstCell property appears to return a cell object, but it doesn't seem to be a valid object. None of the properties seem to work, including CellColNum. If you try the NextCell property to step across the columns, it continues to return additional cell objects that behave the same.

For example, here's some code I ran, where InTextObj is a subcolumn:

cell = tl.obj.InTextObj.FirstCell;

i = 0;

while(typeof(cell)!= "undefined" && i < 1000)

{

    i++;

    cell = cell.NextCellInRow;

}

alert(i);

...that loop runs straight to 1000

Sorry, I didn't finish that before clicking Post.

So, the object returned by FirstCell seems to be bogus. Furthermore, if you do this:

alert(cell.id);

...you get zero, which implies a bogus object.  Furthermore, I did this with the FDK:

  cellId = F_ApiGetId(docId, subcolId, FP_FirstCell);

....and got a zero for the object handle.

So, I think that FirstCell is not what we think it is, or it is unreliable, or something. I think we need somebody to explain this property to us.

Sorry that I couldn't find the answer, but I wanted to at least report what I discovered.

It is interesting that this property appears valid with FrameScript. If I insert a table on the first page of a blank FrameMaker 10 document, and click in the paragraph containing the table anchor, I can run this:

Set oPgf = TextSelection.Begin.Object;

Set oSubCol = oPgf.InTextObj;

Set oCell = oSubCol.FirstCell;

oCell is a valid object; I can query its properties, display its text, etc. However, if the table has a title, the oCell object will actually be the "cell" containing the table title (which is strange).

I don't think the FirstCell property of the SubCol is what you want to use any way. Why not just start with the table object itself and navigate through the cells? Here is how it would be in FrameScript with the selected table, but you can adapt this to ExtendScript:

Set oDoc = ActiveDoc;

Set oTbl = oDoc.SelectedTbl;

Set oCell = oTbl.FirstRowInTbl.FirstCellInRow;

Loop While(oCell)

  // See if the cell contains an anchored frame.

  Get TextList InObject(oCell.FirstPgf) FrameAnchor NewVar(tTextList);

  If tTextList.Count > 0

    // Do something here.

  EndIf

  Set oCell = oCell.NextCellInTbl;

EndLoop

Or, if you want to start with a graphic object, do something like this.

// Get the anchored frame containing the graphic.

Set oAFrame = oGraphic.FrameParent;

// See if the anchored frame is in table cell.

If oAFrame.TextLoc.InTextObj.ObjectName = 'Cell'

  Set oCell = oAFrame.TextLoc.InTextObj;

  // Do something here.

EndIf
