Description:

PtNumeric is a parent class for all numeric widgets. It creates a PtText widget and arrows to let you interact with the widget. It also creates some of the base functionality of numeric widgets.

New resources:

Pt_ARG_NUMERIC_FLAGS

Flags that control the widget's appearance and behavior; any combination of:

Pt_NUMERIC_AUTO_HIGHLIGHT

Autohighlight text when selected.

Pt_NUMERIC_ENABLE_UPDOWN

Display the up/down buttons.

Pt_NUMERIC_HEXADECIMAL

Display the value as a hexadecimal number (applies only to PtNumericInteger).

Pt_NUMERIC_USE_SEPARATORS

Insert comma separators in values (e.g. 1,000).

Pt_NUMERIC_WRAP

Wrap numbers from minimum to maximum and from maximum to minimum.

Pt_ARG_NUMERIC_PREFIX

A prefix string to be added to all entered values.

Pt_ARG_NUMERIC_SPACING

The spacing, in pixels, between the text field and the up/down buttons.

Pt_ARG_NUMERIC_SUFFIX

A suffix string to be added to all entered values.

Pt_ARG_NUMERIC_UPDOWN_WIDTH

The width, in pixels, of the PtScrollbar widget.

Exported subordinate children:

Unless the resources are already defined in PtNumeric, the PtNumeric class uses the resources of its exported subordinate child, PtScrollbar.

The PtNumeric class “inherits” all the resources of its exported subordinate child. Where PtNumeric and its exported subordinate child both define resources having the same name, the resource defined in PtNumeric takes precedence.

Inherited resources:

If the widget modifies an inherited resource, the “Default override” column indicates the new value. This modification affects any subclasses of the widget.
