Supply the Popimage receiver for external-list double-click acceptance.

Initialize only, borrowed Object pointer; default NULL. No local setter

or getter.

For All/Image configurations, a non-NULL originator receives a queued

private MUIM_Popimage_CloseWindow(TRUE) through the application when the

external list emits DoubleClick. It must be a compatible live Popimage

with an existing editor window and remain alive until queued execution

completes. No lifetime reference, compatibility check or queue

cancellation is provided. Other page choices do not use this pointer for

automatic acceptance.

Load editor controls or generate the specification for the active page.

Initialize, set and get in this AROS implementation, despite the header

get-only annotation. Input is a readable specification string; NULL is

treated as 0:128. No input string ownership is transferred.

The last constructor Spec tag is used; Set processes each Spec in tag

order. Input is applied to controls rather than retained verbatim. With

no input, 0:128 is applied; on Pen configuration the existing Penadjust

default remains m5 and Get yields 2:m5. Unsupported prefix/configuration

combinations are not validated; follow the class input restrictions.

Get frees the previous generated string before allocating a new one and

reports TRUE even if allocation fails or no valid selection exists, then

returning literal 0:128 as fallback. Every returned pointer is borrowed:

do not free or modify it, and copy it before another Get or disposal.

Set does not itself free the last getter buffer, but synchronous

notifications can cause another Get.

Pattern output is 0:index+128; vector output is 1:index; color is 2:

plus Penadjust output; external is 3:relative-directory/filename; bitmap

is 5: plus string contents; gradient is the current generated 7:/8:

string. Get is not a lossless serialization of the original input. User

control changes do not automatically emit Imageadjust_Spec

notifications; explicit Set forwards its original tags through Register.

Choose the set and order of editor pages.

Initialize only, LONG. Default MUIV_Imageadjust_Type_All (0). Other

declared values are Image (1), Background (2) and Pen (3). No local

setter or getter.

All: Pattern, Vector, Color, External, Bitmap, Gradient. Image: Pattern,

Vector, Color, External. Background: Pattern, Color, Bitmap, Gradient.

Pen: Color. Supply one of these values; there is no default construction

branch for unknown values and already-created components have no

complete failure cleanup on that path. Keep active-page selection within

the constructed page range: Spec Get indexes its fixed mapping without

an independent bounds check.

Register.mui

Edit an image specification through register pages selected at

construction. All provides Pattern, Vector, Color, External, Bitmap and

Gradient. Image provides Pattern, Vector, Color and External. Background

provides Pattern, Color, Bitmap and Gradient. Pen provides only Color.

These are editor configurations, not a promise that every input

specification can be converted in each configuration.

The class owns Group/Register children, external-entry copies and a

generated getter string. Dispose frees that string, delegates child

disposal and returns zero. Hooks and child callbacks rely on the

instance remaining alive. Originator is borrowed. Normal child lifecycle

and deferred requester/popup callbacks must complete before disposal.

There are eighteen patterns and twenty-four vector choices. Selecting

one deselects the previous tracked choice. With no tracked choice, Get

falls back to 0:128. The color page delegates to Penadjust; the external

page enumerates files below IMAGES:Zune/ when page three is selected,

clearing the old list first. Enumeration is synchronous and recursive,

with no input pumping, depth/cycle bound or complete error status.

Bitmap acknowledgement or Popasl Active FALSE refreshes its preview only

for a nonempty filename. The preview uses a 255-byte buffer including

the 5: prefix and can truncate long paths. Get instead builds from the

string contents and can differ from that preview. A Workbench AppMessage

uses only its first argument and assumes one exists; successful

NameFromLock/AddPart updates preview and string without selecting the

Bitmap page.

Gradient controls select scaled 7: or tiled 8:, angle zero through 179

and two color endpoints. The buttons labelled Vertical and Horizontal

set zero and ninety respectively. Loading a gradient reduces endpoint

channels to eight-bit values and expands each byte back to 32 bits; it

is not a lossless 32-bit roundtrip. Swap exchanges endpoint colors and

refreshes the preview.

Spec input must be a valid string with the prefix and content

appropriate for the available controls. The setter switches on the first

byte and reads from byte two without generally validating the colon or

length. Unknown prefixes leave controls unchanged; 6: parses a number

but implements no selection. Numeric conversions for

pattern/vector/config are unchecked. Passing a prefix for an absent page

is not a supported conversion: several branches use fixed page indices

or missing controls.

For a 2: color input, Penadjust copies a complete 32-byte MUI_PenSpec

starting at input+2. Provide that much readable storage, not merely a

short terminated string. For 3:/4: external input, matching uses a

relative directory/filename; an input with no path separator can

underflow the directory comparison length. Use a valid relative path

with a separator. Output for external selections always uses 3:,

including an input originally using 4:.

External entries copy directory and filename into the List pool, but

allocation failure for either string is not rolled back. Enumeration

ignores many errors and insertion failures and can leave a partial list.

Names ending exactly .mf1 or .mb1 are excluded; other files are not

validated as images. Display labels strip recognized lowercase .mf0,

.mb0, .mbr and .image suffixes. Directory recursion follows the ExAll

type classification without resolving soft-link targets or detecting

cycles.
