Method Details

getAccessibleRole

public AccessibleRole getAccessibleRole()
Returns the role of this accessible object.
Overrides:
getAccessibleRole in interface Component.AccessibleAWTComponent
Returns:
the instance of AccessibleRole, which describes this object.

getAccessibleStateSet

public AccessibleStateSet getAccessibleStateSet()
Returns the state set of this accessible object.
Overrides:
getAccessibleStateSet in interface Component.AccessibleAWTComponent
Returns:
a set of AccessibleStates which represent the current state of the accessible object.

getAccessibleValue

public AccessibleValue getAccessibleValue()
Returns an implementation of the AccessibleValue interface for this accessible object. In this case, the current instance is simply returned (with a more appropriate type), as it also implements the accessible value as well as the context.
Overrides:
getAccessibleValue in interface AccessibleContext
Returns:
the accessible value associated with this context.

getCurrentAccessibleValue

public Number getCurrentAccessibleValue()
Returns the current value of this accessible object. In this case, this is the same as the value for the scrollbar, wrapped in an Integer object.
Specified by:
getCurrentAccessibleValue in interface AccessibleValue
Returns:
the numeric value of this scrollbar.

getMaximumAccessibleValue

public Number getMaximumAccessibleValue()
Returns the maximum acceptable accessible value used by this object. In this case, this is the same as the maximum value of the scrollbar, wrapped in an object.
Specified by:
getMaximumAccessibleValue in interface AccessibleValue
Returns:
the maximum value of this scrollbar.

getMinimumAccessibleValue

public Number getMinimumAccessibleValue()
Returns the minimum acceptable accessible value used by this object. In this case, this is the same as the minimum value of the scrollbar, wrapped in an object.
Specified by:
getMinimumAccessibleValue in interface AccessibleValue
Returns:
the minimum value of this scrollbar.

setCurrentAccessibleValue

public boolean setCurrentAccessibleValue(Number number)
Sets the current value of this accessible object to that supplied. In this case, the value of the scrollbar is set, and this method always returns true.
Specified by:
setCurrentAccessibleValue in interface AccessibleValue
Parameters:
number - the new accessible value.
Returns:
true if the value was set.
