Select horizontal orientation when true; vertical otherwise. Default

TRUE.

BOOL; initialize, set and get.

Getter normalizes to TRUE/FALSE. Runtime setting immediately

recalculates knob dimensions using font and application preferences,

invalidates caches and requests a full redraw. Perform it with valid

setup/connection state; it does not itself request parent relayout.

Construction stores the flag without that runtime calculation.

Obsolete name with the same attribute ID as MUIA_Numeric_Value.

Available in the header only when MUI_OBSOLETE is enabled. Same type and

access as Numeric_Value.

Use MUIA_Numeric_Value in new code. There is no separate Slider state or

conversion for this alias; inherited Numeric behavior and limitations

apply.

Obsolete name with the same attribute ID as MUIA_Numeric_Max.

Available in the header only when MUI_OBSOLETE is enabled. Same type and

access as Numeric_Max.

Use MUIA_Numeric_Max in new code. There is no separate Slider state or

conversion for this alias; inherited Numeric behavior and limitations

apply.

Obsolete name with the same attribute ID as MUIA_Numeric_Min.

Available in the header only when MUI_OBSOLETE is enabled. Same type and

access as Numeric_Min.

Use MUIA_Numeric_Min in new code. There is no separate Slider state or

conversion for this alias; inherited Numeric behavior and limitations

apply.

Suppress drawing the text inside the knob. Default FALSE.

BOOL; initialize only. No local getter or runtime setter.

Value changes and notifications continue normally. Knob dimensions are

still calculated by formatting the selected value range. Quiet does not

mean release-only updates or notification suppression.

Obsolete name with the same attribute ID as MUIA_Numeric_Reverse.

Available in the header only when MUI_OBSOLETE is enabled. Same type and

access as Numeric_Reverse.

Use MUIA_Numeric_Reverse in new code. There is no separate Slider state

or conversion for this alias; inherited Numeric behavior and limitations

apply.

Numeric.mui

Display Numeric Value with a custom drawn knob and optional text.

Default orientation is horizontal; Quiet defaults FALSE. Construction

prepends SliderBack, Knob font and Slider frame before caller tags. This

class is a Numeric subclass and does not own a Prop child or native

proportional gadget.

Setup calls Numeric, prepares a knob background image and calculates

knob dimensions, then registers a mouse handler. Cleanup releases the

background and removes the handler before Numeric Cleanup. Show shows

the prepared image and returns one regardless of superclass result; Hide

hides it and invalidates the cached position. Dispose frees owned copied

display text, then Numeric. Complete Hide/Cleanup first.

Knob sizing calls Stringify for every value from Min to Max. If the

computed span exceeds MUI_MAXMAX it instead scans zero through

MUI_MAXMAX, which can miss wide strings for the real range.

CheckAllSizes is ignored by this scan. Signed span/loop arithmetic is

unchecked; a maximum at LONG_MAX can overflow the loop increment.

Draw maps Value to pixel offset and caches both offset and a copied

Stringify result. Text-copy allocation is unchecked before strlen. Setup

does not turn knob-background preparation failure into FALSE. Mouse

handling requires geometry established by drawing and a nonnegative

travel length.

A non-shift click on the knob starts dragging and sets Pressed. A

background click changes Value by one with Reverse honored. A later

non-SELECTDOWN button event ends a pressed drag. Mouse moves map offset

through ScaleToValue on a zero-based scale and use the Numeric setter

directly to preserve pixel offset. Notifications remain enabled even in

Quiet mode.

Slider HandleEvent handles mouse events only and does not delegate to

Numeric. Numeric Setup separately installs its raw-key handler with the

Numeric class. Keep normal event registration intact; direct calls to

Slider HandleEvent are not a substitute for that handler.

Value/Min/Max/Format setters invalidate cached position/text, but only

orientation setting explicitly recalculates knob dimensions after Setup.

Thus live format/bound changes can leave stale measured knob size

despite Numeric requesting parent relayout. Reverse alone does not

invalidate the position cache. Quiet hides text only; it does not reduce

the knob-size scan or suppress notifications.
