Questions about xBBROWSE-Cell-Bitmaps in design-mode.

[ukoenig]

Hello,

I have some questions about Cell-Bitmaps
in design-mode.

I start with a empty browse.



Next, i send a Bitmap to xbrowse.
The cell-height is not adjusted.
Refresh, update doesn't help



When I close the dialog und reopen it.
The cell-height is ok.



Now, i can fill the browser with different bitmaps.
When the end of the browser is reached,
is it possible, to clear the bmp-array ?

Code: Select all  Expand view

If we go through the present code, xbrowse calculates the row height on the basis of bitmap heights only at the time of initialization. If we set any bitmap when the xbrowse is already open that height is not readjusted.

We do not know if FWH is planning to recalculate ( in the coming version) the row height if we add a bitmap at runtime.

But what we can do is, when we add a bitmap when the browse is running, we can also reset the oBrw:nRowHeight to fit the new bitmap height and Refresh. This will work

Code: Select all  Expand view

oCol:AddBmpFile( cbmpfilename )
nHeight := ATail( oCol:aBitmaps )[ 2 ]
if oBrw:nRowHeight < nHeight  - 2
   oBrw:nRowHeight := nHeight + 2
endif
oBrw:Refresh()

Hello

I checked still another version
At first i look, if the user wants to test a cellbitmap
When yes, i get the height of the testbitmap.
It works as well, but with a new test
all row-heights have the size of the new test-bitmap.
The bitmaps from the test before, are still in the array.
I think, the best way how to do it is,
to clear the bmp-array before i start to test a new bitmap.
I still have to check the sample from Mr. nageswaragunupudi
// ---------------------------------------------------------------

Code: Select all  Expand view


FUNCTION xBNEWF1(oLbx1,oLbx2,xBFont1,xBFont2)
local nBmpHeight, oBmp, cBMP
......
......
IF !empty(e_BRBMP)  //  there is a cell-Bitmap
   cBMP := ALLTRIM(e_BRBMP) + ".BMP"    // User-selection
   DEFINE BITMAP oBmp FILE cBmp
   nBmpHeight := oBmp:nHeight
   oBmp:End()
ENDIF
......
......
for n = 1 to 3   // 3 Cols
  ......
  ......
   IF !empty(cBMP)
      oCol := oLbx1:aCols[ 1 ]:AddBmpFile(cBMP)
      oLbx1:aCols[ 1 ]:bBmpData := {|| oLbx1:nArrayAt }
      oLbx1:nRowHeight := nBmpHeight  // The test-bitmap
   ELSE
     oLbx1:aCols[ 1 ]:bBmpData := NIL 
   ENDIF
next
.......

I am not sure, but can you try this?
Whenever you make such changes, call oBrw:Adjust() and then oBrw:Refresh()

Hello NagesWaraRao,
this is a little off topic but do you think xBrowser could have variable row high depending
on the content of the row. I mean every row you see maybe another high.

Hello,

I added just one line.
Before i start, to fill <Col 1 > with bitmaps the user selected,
I set the bitmap-arraylist to 0
( oLbx1:Adjust() i checked, there was no difference )

ASIZE( oLbx1:aCols[1]:aBitmaps,0)

Now every time, the user wants to test a bitmap,
he starts with a clean browser.
The Cell-hight is allways adjusted to the bitmap-height.

Regards

Uwe
