Set/Change Dialog Image

[BJ]

I know the basics of displaying an image in a dialog, but Is it possible to make a button in the dialog or an outside macro change the path of the specified image so that the image will change?

Function dialog_image
Trigger F12     

Code:

;\Dialog_Editor

str dd=
;BEGIN DIALOG
;0 "" 0x90C80AC8 0x0 0 0 248 152 "Set Image"
;3 Static 0x5400000E 0x0 16 16 96 96 ""

;END DIALOG
;DIALOG EDITOR: "" 0x2040500 "*" "" "" ""

str controls = "3 4"
str sb3 sb4
sb3 = "$desktop$\img\1.png"
sb4 = "$desktop$\img\2.png"
if(!ShowDialog(dd &sub.DlgProc &controls)) ret


#sub DlgProc

Update:

I found the dlg_button_images function in the archive. Is there a way to make this work with the static bitmap that can be used in the dialog?

Function StaticControlSetImage

Code:

Copy      Help

;/
function hwnd [$imageFile] [hbitmap]

;Displays image in a static control in a dialog.

;hwnd - static control handle.
;imageFile - image file. Can be bmp, png, gif, jpg. The function uses <help>LoadPictureFile</help>. If not used, can be "".
;hbitmap - bitmap handle. Can be used instead of imageFile. The caller can delete it immediately (this function copies it). If omitted or 0, the function uses imageFile.

;REMARKS
;If the control has style SS_REALSIZEIMAGE, resizes it to display whole image.
;Unlike STM_SETIMAGE, correctly displays alpha bitmaps.


if(hbitmap) hbitmap=CopyImage(hbitmap IMAGE_BITMAP 0 0 0)
else hbitmap=LoadPictureFile(imageFile); if(hbitmap=0) end "LoadPictureFile failed"

type __SICSB4249 __MemBmp'mb wid hei

__SICSB4249* p=+GetProp(hwnd "__SICSB4249")
if(!p) SetWindowSubclass(hwnd &sub.SubclassProc 1 p._new)

p.mb.Attach(hbitmap)

BITMAP b; GetObject p.mb.bm sizeof(BITMAP) &b
