Combobox with bitmaps

[TimStone]

I've searched all over for this, and of course I've experimented without success.

I want to have a combobox where the dropdown includes a bitmap for each line.

The docs say to create an array of items, and an array of bitmaps ( which do reside in the RESOURCES file ). I've done that. It then seems to say the bitmap will display next to the corresponding item array ( ie. bitmap 4 in the array of bitmaps should load to item 4 of the drop down list ).

I've looked everywhere for a sample but can't find it ( docs, online docs, forum, etc. ).

Can anyone provide a sample ? Thanks.

Hello Tim,



Samples : Ownerdra.prg
( Bitmaps from Disk and resource )

REDEFINE COMBOBOX oCbx1 VAR cItem2 ;
ID 120 OF oDlg ;
ITEMS { "Drive A:", "Drive C:", "Ram Drive", "Net Drive" } ;
BITMAPS { "..\bitmaps\fdrive.bmp",;
"..\bitmaps\hdrive.bmp",; // from Disk
"Arrow",; // from Resource
"..\bitmaps\netdrive.bmp" }

Best Regards

How do you have the control in the .rc file ?

I am using:
REDEFINE COMBOBOX oCB2 VAR cAptClr ;
ID 4065 OF oCalDlg ;
ITEMS { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10" } ;
BITMAPS { "CJ01","CJ02", "CJ03", "CJ04", "CJ05", "CJ06", "CJ07", ;
"CJ08","CJ09", "CJ10" } ;
MESSAGE "Enter the technician, or service area, for this appointment"

And:
CONTROL "", 4065, "ComboBox", CBS_DROPDOWNLIST | CBS_OWNERDRAWFIXED | WS_TABSTOP, 300, 30, 80, 100

My bitmaps are 10 x 10 Solid color squares.

They won't show up ...

Thanks.

I think the issue is with my bitmaps. I will work with them today. Initially I had 10x10 and they didn't display. Then I tried 16x16 but I wanted them larger so I went to 16 x 32 ( wide ) and they didn't work. I did get a 16x16 to display. The space is being provided for them.

Thanks

Tim,

my Tests using 16x16, 24x24 and 24x32
It seems, only 16 x 16 is possible.
I changed the Font, to force the Rowheight to be bigger,
but the Bmp is resized as well.
Maybe it is possible, to delete BMP-resizing ( keeping the original BMP-Size ? )
I think to adjust the Row-height to the BMP ( in case BMP-height >= Font-height, like in xBrowse )
it would be a better Solution.
I will have a look at the Class Combobox.



Best Regards

I had tried 8 bit and even they didn't work. It would appear 16x16 Alpha does work, so I'm resetting them to that and hopefully this will be done. I use Axialis for my icons and bitmaps so it really is very easy to make changes.

Thanks.
