Detailed Description

This interface should be implemented by accessible objects that represent a value. Examples are spinner, slider, dial and scroll bar.

Instead of forcing the user to deal with the individual parts of the widgets, this interface gives an easier approach to the kind of widget it represents.

Usually this interface is implemented by classes that also implement QAccessibleInterface .

IAccessible2 Specification

class PySide2.QtGui.QAccessibleValueInterface
PySide2.QtGui.QAccessibleValueInterface.currentValue()
Return type

object

Returns the current value of the widget. This is usually a double or int.

PySide2.QtGui.QAccessibleValueInterface.maximumValue()
Return type

object

Returns the maximum value this object accepts.

PySide2.QtGui.QAccessibleValueInterface.minimumStepSize()
Return type

object

Returns the minimum step size for the accessible. This is the smalles increment that makes sense when changing the value. When programatically changing the value it should always be a multiple of the minimum step size.

Some tools use this value even when the setCurrentValue does not perform any action. Progress bars for example are read-only but should return their range divided by 100.

PySide2.QtGui.QAccessibleValueInterface.minimumValue()
Return type

object

Returns the minimum value this object accepts.

PySide2.QtGui.QAccessibleValueInterface.setCurrentValue(value)
Parameters

value – object

Sets the value . If the desired value is out of the range of permissible values, this call will be ignored.
