## Detailed Description

This is an abstract class which serves as a base class for numeric properties, like wxIntProperty, wxUIntProperty, wxFloatProperty.

Supported special attributes:

- wxPG_ATTR_MIN, wxPG_ATTR_MAX: Specify acceptable value range.
- wxPG_ATTR_SPINCTRL_STEP: How much number changes when SpinCtrl editor button is pressed (or up/down on keyboard).
- wxPG_ATTR_SPINCTRL_WRAP: Specify if value modified with SpinCtrl editor wraps at Min/Max.
- wxPG_ATTR_SPINCTRL_MOTION: Specify if value can also by changed with SpinCtrl editor by moving mouse when left mouse button is being pressed.

## Constructor & Destructor Documentation

## ◆ wxNumericProperty()

wxNumericProperty::wxNumericProperty | ( | const wxString & | label,
|  | const wxString & | name
| ) |  |
| protected

Constructor is protected because wxNumericProperty is only a base class for other numeric property classes.

## Member Function Documentation

## ◆ AddSpinStepValue()

virtual wxVariant wxNumericProperty::AddSpinStepValue | ( | long | stepScale | ) | const
| pure virtual

Returns what would be the new value of the property after adding SpinCtrl editor step to the current value.

Current value range and wrapping (if enabled) are taken into account. This member has to be implemented in derived properties.

Parameters

  stepScale | SpinCtrl editor step is first multiplied by this factor and next added to the current value.

Returns
  Value which property would have after adding SpinCtrl editor step.

Remarks
  Current property value is not changed.

Implemented in wxFloatProperty, wxUIntProperty, and wxIntProperty.

## ◆ DoSetAttribute()

virtual bool wxNumericProperty::DoSetAttribute | ( | const wxString & | name,
|  | wxVariant & | value
| ) |  |
| virtual

Reimplement this member function to add special handling for attributes of this property.

Returns
  Return false to have the attribute automatically stored in m_attributes. Default implementation simply does that and nothing else.

Remarks
  To actually set property attribute values from the application, use wxPGProperty::SetAttribute() instead.

Reimplemented from wxPGProperty.

Reimplemented in wxFloatProperty, and wxUIntProperty.

## ◆ UseSpinMotion()

bool wxNumericProperty::UseSpinMotion | ( |  | ) | const

Return true if value can be changed with SpinCtrl editor by moving the mouse.
