XBrowse Multi Line Cell With Different Fonts

[David Williams]

Hi All

I'm trying to show a calendar type browse where within each cell, I have 3 lines of text. I want to show the second line in a larger font with the first and third line smaller.

Any suggestions?

TIA David

Hello David,

please have a look at /samples/Testxbr6.prg

The above sample shows usage of oCol:bPaintText.

This offers total flexibility to the programmer and he can paint any cell in his own way.

There is another feature where two or more columns can be painted in a single cell.
By specifying something like
oBrw:aCols[ 1 ]:SetColsAsRows( 1, 2, 3 ), contents of columns 1,2,3 are painted as 3 rows in column 1 and columns 2 and 3 are not displayed. We can specify different fonts, colors, alignment, etc to these columns as usual, except that they are painted under one another as subrows of the cell instead of showing in adjacent columns.

Here is an example. Please compile and run as it is.

Code: Select all | Expand

function MultiLineCells

   local oDlg, oBrw, aFont[ 3 ]
   local aData    := Array( 4, 12 )
   local n,i,j

   n  := 1
   for i := 1 to 4
      for j := 1 to 10 step 3
         aData[ i, j ]     := NToCDOW( ( n - 1 ) % 7 + 1 )
         aData[ i, j + 1 ] := n
         aData[ i, j + 2 ] := "Some details that may take more than one line"
         n++
      next
   next

   DEFINE FONT aFont[ 1 ] NAME "TAHOMA"  SIZE 0,-16 BOLD
   DEFINE FONT aFont[ 2 ] NAME "IMPACT"  SIZE 0,-34
   DEFINE FONT aFont[ 3 ] NAME "TIMES ROMAN" SIZE 0,-12 ITALIC

   DEFINE DIALOG oDlg SIZE 700,500 PIXEL
   @ 10,10 XBROWSE oBrw SIZE -10,-10 PIXEL OF oDlg DATASOURCE aData AUTOCOLS ;
      LINES NOBORDER

   WITH OBJECT oBrw
      :nWidths    := 150
      :nRowHeight := 100
      for i := 1 to 10 STEP 3
         WITH OBJECT :aCols[ i ]
            :oDataFont     := aFont[ 1 ]
            :nDataStrAlign := AL_CENTER
         END
         WITH OBJECT :aCols[ i + 1 ]
            :oDataFont     := aFont[ 2 ]
            :nDataStrAlign := AL_CENTER
            :bClrStd       := { || { CLR_HRED, CLR_WHITE } }
         END
         WITH OBJECT :aCols[ i + 2 ]
            :oDataFont     := aFont[ 3 ]
            :nDataLines    := 2
         END
         :aCols[ i ]:SetColsAsRows( i, i + 1, i + 2 )
      next
      //
      :CreateFromCode()
   END

   ACTIVATE DIALOG oDlg CENTERED
   AEval( aFont, { |o| o:End() } )

return nil
 

To understand the concept better, please insert this code just after preparing the array

Code: Select all | Expand

XBROWSER aData

The raw array data looks like this.


Now let us apply formatting to the columns. Every 3rd columns has the same formatting.
For this just comment the line of code in the above sample

Code: Select all | Expand

//         :aCols[ i ]:SetColsAsRows( i, i + 1, i + 2 )
 

Without this line, each column is displayed side by side.


Now let us paint cols 2 and 3 under col-1. cols 5 and 6 under col 4 and so on.
This is done by restoring the line

Code: Select all | Expand

         :aCols[ i ]:SetColsAsRows( i, i + 1, i + 2 )

Now the final outcome is what we see in the first screen-shot

Hallo Otto

Rao's sample runs fine with FWH1307 but not with FWH1203 - there are many changes in xbrowse.prg...

[Otto]

Hello Anton,
thank you. You are right. With the new Fivewin Version this sample is working fine.
Best regards,
Otto

[David Williams]

Thanks Everyone,

Roa, your sample works perfect and helps me a lot with understanding the power of XBrowse.

Thanks again
David

With these changes in version 12.03 I managed to work:

Code: Select all | Expand

METHOD PaintData( nRow, nCol, nHeight, lHighLite, lSelected, nOrder, nPaintRow ) CLASS TXBrwColumn

.../...

   if Empty( ::nDataHeight )
      ::nDataHeight  := ::DataHeight()
   endif

   nDataHeight    := If( Empty( ::aRows ), nHeight, ::nDataHeight )
   ::PaintCell( nRow, nCol, nDataHeight, lHighLite, lSelected, nOrder, nPaintRow )

   if ! Empty( ::aRows )
      for n := 2 to Len( ::aRows )

         .../...

         nDataHeight    := If( n == Len( ::aRows ), nHeight, oCol:nDataHeight )
         if Empty( nDataHeight )
            if Empty( oCol:nDataHeight )
               oCol:nDataHeight := oCol:DataHeight()
            endif
            nDataHeight := oCol:nDataHeight
         endif
         oCol:PaintCell( nRow, nCol, nDataHeight, lHighLite, lSelected, nOrder, nPaintRow )
      next n

   endif

return nil

Dear Mr. Rao,
can you please Show me how to get the right values from a dblClick.
Thanks in advance
Otto


Brw:bLDblClick := { |nKey| msginfo( ) }

[nageswaragunupudi]

Dear Mr Otto

I do not clearly understand what are the right values you want to know. Can you please explain clearly?

oBrw:bLDClick := { |nRow, nCol, nFlags, oBrw| <func>( nRow,nCol,nFlags,oBrw )}
oCol:bLDClickData := { |nRow, nCol, nFlags, oBrw| <func>( nRow,nCol,nFlags,oCol )}

[Otto]

Dear Mr. Rao,
I tried:
oBrw:bLDblClick := { |nKey| msginfo( oBrw:aCols[ 1 ]:Value ) }
But this gives me always the value of the first column.
I would need the value of the column the user clicks.
Thanks in advance
Otto

[Rick Lipkin]

Otto

I asked a similar question and Rao suggested using this ..

Code: Select all | Expand

cText := oLbx:SelectedCol():Value
 

This will give you the text within the cell clicked.

Otto, not sure if you're looking for:

Code: Select all | Expand

      :bLDblClick       := { | nRow, nCol, nFlag | MsgInfo( oBrw:aCols[ oBrw:MouseColPos( nCol ) ]:Value ) }
 

[nageswaragunupudi]

Mr Otto

Mr Rick's suggestion is correct.

oBrw:bLDClick := { || MsgInfo( oBrw:SelectedCol():Value ) }

Mr Navarro

Your solution can give wrong results in some cases.
MouseColPos( nCol ) gives you the number of visible column in the window. There could be some hidden columns or columns to the left of the visible area.

We should take oBrw:ColAtPos( MouseColPos( nCol ) )
Instead we better take oBrw:SelectedCol().

[cnavarro]

Mr. Rao thank you very much for your explanations and arguments
