Detailed Description

template<typename T>
class pongasoft::VST::GUI::Params::DefaultEditorImpl< T >

Default implementation of the editor interface.

Simply delegates the calls to the parameter while maintaining an initial value (for rollback()) and state (already completed).

Private API

This is part of the internal/private API of Jamba and should not be used directly.

Member Function Documentation

commit()

tresult commit ( )

inlineoverridevirtual

Commits all the changes applied to the parameter.

Note

If commit() or rollback() has already been called this method does nothing.

Implements IGUIParameter::Editor.

rollback()

tresult rollback ( )

inlineoverridevirtual

Rollback all the changes that were made to this parameter (since this editor was created).

Note

If commit() or rollback() has already been called this method does nothing.

Implements IGUIParameter::Editor.

setValue()

tresult setValue ( T const &  iValue )

inlineoverridevirtual

Unconditionaly sets the value of the parameter to the value provided.

Parameters

iValue

the value to set

Returns

kResultOk if successful

Implements ITGUIParameter< T >::ITEditor.

updateValue()

bool updateValue ( T const &  iValue )

inlineoverridevirtual

First check if the value provided (iValue) is different from the current value and if that is the case then updates it to the new value.

Note

If the type T does not provide a way to compare the value, then this call will delegate to setValue(ParamType const &) and return true.

Parameters

iValue

the value to update

Returns

true if the value was updated

Implements ITGUIParameter< T >::ITEditor.
