4 Get border parameters
5 Read async button state
6 Get selected async button
Provided by 3DIcons
Get border number
Entry
R0 = 0
R1 -> icon block
Exit
R0 = border number, or -1 if the icon has no 3D border
Returns the number of the 3D border of the specified icon. -1 is returned if the icon has no 3D border.
Get border width
Entry
R0 = 1
R2 = border number (0-6)
Exit
R0 = width in OS units, or 0 if R2 did not contain a valid border number
Returns the width of the 3D border outside the icon‘s bounding box. 0 is returned if an invalid border type is specified.
Get bounding box in registers
Entry
R0 = 2
R1 -> icon block
Exit
R2 = XMin
R3 = YMin
R4 = XMax
R5 = YMax
Returns the bounding box of the icon, including the 3D border if present.
Get bounding box in block
Entry
R0 = 3
R1 -> pointer to icon block
R2 -> pointer to 16-byte block to receive bounding box
Exit
R2 + 0 = XMin
R2 + 4 = YMin
R2 + 8 = XMax
R2 + 12 = YMax
Returns the bounding box of the icon, including the 3D border if present.
Get border parameters
Entry
R0 = 4
R1 -> icon block
Exit
R0 = slabbed-out colour + slabbed-in colour * 16 or -1 for bad validation
R2 = border-1 colour + border-2 colour * 16
R3 = channel colour + slabbing time * 16
Returns the parameters of the border command, substituting defaults for unspecified parameters.
Read async button state
Entry
R0 = 5
R2 = window handle
R3 = icon handle
Exit
R0 = current state of icon (0 for popped out, 1 for popped in)
Get selected async button
Entry
R0 = 6
R2 = window handle
R3 = ESG group
Exit
R0 = Async icon number that is popped in, or -1 for none
Checks the specified window and returns which icon in the ESG is currently popped in using the async list.
