Trying to display image using function WB_BITMAP_SHOW

[wesleynz]

I've created a simple program to display an initial image like the one we see in SE80. I also noticed it uses a function called WB_BITMAP_SHOW, so I created a FORM 'z_image' calling the same function. I uploaded an image using SE78 and tried to call the image as follows:

  CALL FUNCTION 'WB_BITMAP_SHOW'
    EXPORTING
      image_name      = 'IMG_PEDIDO'
*     container       = 
*     PARENT          = ''
*      stretch_picture = 'X'.
* IMPORTING
*   IMAGE_CONTROL          =
*   CUSTOM_CONTAINER       = 

The 'custom_control_1' is the area where image is supposed to appear, but nothing appears even trying different ways. What am I doing wrong? Thank you in advance.

You have to pass either CONTAINER (name) or PARENT (instance) to the FM so it will be able to use those to create/use container for the picture, or don't use the FM and directly call classes such as CL_GUI_PICTURE and CL_GUI_CUSTOM_CONTAINER which are well documented.)
