How to get coordinates of table cell in a multi column text frame

Hi All,

 

I am using following code to get the table coordinate as it shown in the info panel.

 

InterfacePtr<ITextStoryThread> storyThread(txtModel->QueryStoryThread(startPos + 1));
if(storyThread){
GridAddress gridAdd;
ParcelKey parcelKey;
 
InterfacePtr<ICellContent> cellcontentp(storyThread, UseDefaultIID());
if(cellcontentp){
gridAdd = cellcontentp->GetGridAddress();
parcelKey = cellcontentp->GetNthParcelKey(0);
}
else {
break;
}
 
InterfacePtr<ITableLayout> tableLayout(tableModel, UseDefaultIID());
if(tableLayout){
ITableLayout::frame_iterator begframeIter = tableLayout->begin_frame_iterator();
ITableLayout::frame_iterator endframeIter = tableLayout->end_frame_iterator();
 
// Having problem in getting ITableFrame directly from the startPos
// So iterate over the table frames to find which one contains the address of our cell content
for(;begframeIter != endframeIter; ++begframeIter){
InterfacePtr<ITableFrame> tableFrame(begframeIter->QueryFrame());
if(tableFrame){
CellParcelAddr cpa(gridAdd, parcelKey);
if(tableFrame->Contains(cpa)){
GridID gridID(cellcontentp->GetGridID());
GridAddress gridAddress(cellcontentp->GetGridAddress());
 
// Till here, the point seems to be right, we need to convert to table and then to frame coords i guess
// InterfacePtr<ITableGeometry> tableGeo(tableModel, UseDefaultIID());
// PMRect cellRect = tableGeo->GetCellBounds(gridAddress);
PMRect cellRect = tableFrame->GetCellBounds(gridAddress);
int32 xPos = cellRect.Left();
int32 yPos = cellRect.Bottom() - cellRect.Height();
}
}
}
}
}
 
Can some suggest a good approach to get the x,y coordinate of table cell in multi column frame.

 

Regards,

Alam

Correct answer Pickory

This should give you the rect relative to parent frame. Seems to work with tables within tables.

 

How you arrive at storythreadp and key is up to you.

 

As Dirk mentioned you will have to consider indents and others.

 

                InterfacePtr<ICellContent> cellcontentp(storythreadp, UseDefaultIID());

                if ( cellcontentp )

.... .... ...

                    PMRect cr = cellcontentp->GetCellPathBounds ( key );

                    PMMatrix m = cellcontentp->GetParcelToFrameMatrix ( key );

                    m.Transform ( &cr );

... ... ...

    Hi Pictory,

     

    Thanks for info yes the above code works

    After transform api, I checked PMRect cr for left, top, bottom and right

    and it gives the cell x,y position but not the x,y position of start of text in each cell.

    And I further used following code to get the x,y position from the start of text in each cell

    InterfacePtr<ITableModel>tableModel(tableFrame->QueryModel());

    if(!tableModel){

    break;

    }

    // Getting cell inset

    InterfacePtr<ITableAttrAccessor> attrAccessor(tableModel, UseDefaultIID());

    if (!attrAccessor)

    break;

     

            InterfacePtr<ITableAttrRealNumber> parentLeftInsetNumber(attrAccessor->QueryCellAttribute(gridAddress, kCellAttrLeftInsetBoss, IID_ITABLEATTRREALNUMBER), UseDefaultIID());

            PMReal parentLeftInset = parentLeftInsetNumber->Get();

    Look at IWaxLine

     

                            InterfacePtr<ITableModel> tableModel(cellcontentp->GetTableModel(), UseDefaultIID());

                            if ( !tableModel )

                                break;

                            InterfacePtr<ITableAttrAccessor> attrAccessor(tableModel, UseDefaultIID());

                            if ( !attrAccessor )

                                break;

                            InterfacePtr<ITableAttrRealNumber> leftInset((ITableAttrRealNumber*)attrAccessor->QueryCellAttribute

                                                                         (cellcontentp->GetGridAddress(), kCellAttrLeftInsetBoss, IID_ITABLEATTRREALNUMBER));

                            PMReal leftInsetValue = 0;

                            if (leftInset != nil) {

                                leftInsetValue = leftInset->Get();

                            }

    Not sure whether it is relevant, but I iterate the cells straight from ITableModel.

    Using QueryCellContentBoss() I likely end up at the same ICellContent as your cellcontentp.

    To the parcel via GetNthParcelKey.

    GetParcelToFrameMatrix looks promising (growing tx).

    There could be better ways, I've covered only few interfaces.

     

    Of course you should also handle overset, graphics cells etc.

      Btw, the parcel's GetParcelFrameUID() is the matching kFrameItemBoss (text column) within the kMultiColumnItemBoss (actual text frame) if you prefer to compute on coordinates.

      Hi Dirk,

      I could get the ITableFrame from api GetParcelFrameUID and if I use GetCellBounds() then it return same top, left for first column in each row whereas left of 2nd and 3rd row should be different.

      Let me know the next step that I should follow

      Have a look at the transforms in ITableFrame.h.

       

      virtual PMMatrix GetToFrameMatrix() const = 0;

      Hi @alam_84 ,

      search the InDesign forum, recently we had a solution for this:
