Problem with a Combobox
Posted: Fri Feb 15, 2019 09:11 AM

I have an array of 3 items : name,image,struttura

AaDd(alist_temp,{ alltrim(SZ->NAME),alltrim(SZ->IMAGE), alltrim(SZ->struttura) })

and for show a combo I made

@ 53, 55 COMBOBOX aGet[5] VAR nServizio ITEMS ArrTranspose( aServizi )[ 1] ;
OF oDlg SIZE 100, 120 PIXEL FONT oFont WHEN aGet[2]:nOption=2 .or. aGet[2]:nOption=3
BITMAPS ArrTranspose( aservizi )[ 2]

But it show this

Probable not read the image is into aServizi /2field

I have the images on .\images\servizi

Combobox supports bmp files only. Not png files.

You can convert PNG to BMP for the combobox-usage

viewtopic.php?f=3&t=35547&p=211638&hilit=TransformBitmap#p211638

hBmp := FW_ReadImage( nil, "Lock.png" )[ 1 ]
hNew := FW_TransformBitmap( hBmp, NIL, 0.08 ) // resize for combobox usage
FW_SaveImage( hNew, "Lock.bmp" ) // to be used

regards
Uwe

Since 1995 ( the first release of FW 1.9 )

i work with FW.

If you have any questions about special functions, maybe i can help.

Uwe,
This thing is very interesting. I store files in an archive but it is managed by the user and the files can be of various types.
Generally, the end user could load png or even gif, jpg and Bmp.
How can I check if the files are png or are these functions good for any format?
and then I could create temporary images and then delete them every time?

aTest

Code (fw): Select all Collapse

aElementiBmp:={ }  //new array
cFoldertemp:=".\bitmaps\mini\"
For n= 1 to Len(aElementi)  //on aElementi there are a fields where I save file img

                   Converti_Immagine_Bmp(ArrTranspose( aElementi )[ 3],cFolderTemp,"temp_"+alltrim(str(n)))

aadd(aElementiBmp,"temp_"+alltrim(str(n)))

next
//-------------------------------------------------------------------------------------//
Function Converti_Immagine_Bmp(cFile,cFolderTemp,cNewName)
   Local ext:=".Bmp"
   Local nResize:=0.08
   Local hBmp := FW_ReadImage( nil, cFile )[ 1 ]
   Local hNew := FW_TransformBitmap( hBmp, NIL, nResize ) // resize for combobox usage
     FW_SaveImage( hNew, cFolderTemp+cNewName+ext )
 Return   cFolderTemp+cNewName+ext

this is the result (probable error )

I check and I saw I have only 4 images original

1 png of 312x315
2 png 135X132
3 png 165x161
4 png 363X350

why I have 4 smaller bmp ?
and if you see good there is black back ( transparent is not converted to white)

But on the combo I have this . This conversion could work if we could only convert all the images in the same format
