Pendisplay.mui

Display a pen as a draggable button that opens a Penadjust window when

Pressed becomes FALSE. It inherits Pendisplay color attributes and their

ownership, reference and notification behavior. Constructor defaults

include ButtonFrame, inner spacing four, button background, RelVerify

input mode and Draggable TRUE, followed by caller tags.

MUIA_Window_Title is consumed at construction as a borrowed popup-title

pointer, default NULL. This is not a local set/get attribute: changing

that tag later does not update the saved title. Keep the string valid

for every popup creation. Pen state remains in the inherited Pendisplay

specification.

Opening lazily creates a window containing Penadjust and localized

OK/Cancel buttons, adds it to the application and opens it. An existing

popup is reused without resampling the current pen. Creation/open

failure is not reported by the internal open method, which returns one;

failed opening closes the created window with cancellation.

OK reads the editor specification, copies it into Pendisplay and

disposes the popup. Cancel or the window close request discards edits.

Button and close-request notifications enqueue the internal close method

through Application_PushMethod. Hide and DisconnectParent close/dispose

an existing popup without committing edits before delegating to the

superclass.

Use a live application connection and keep this object alive until its

queued close calls have run. The private close method assumes an

existing popup and does not guard repeated or stale calls. Hide clears

wnd but leaves the penadjust pointer stale; no independent queue

cancellation occurs here. Do not invoke internal window methods as

public API. There is no local Dispose override to replace normal

Hide/DisconnectParent ordering.

Opening obtains the inherited Spec without checking getter success

before constructing Penadjust. Any Reference must therefore be live and

provide a valid full specification. With Reference attached, OK changes

hidden local Pendisplay state; it does not change the referenced object

or override redirected getters.
