Detailed Description

Abstract base class for EmbAJAXOptionSelect.

Member Function Documentation

◆ selectedOption()

uint8_t EmbAJAXOptionSelectBase::selectedOption ( ) const
Returns
the index of the currently selected option

◆ selectOption()

void EmbAJAXOptionSelectBase::selectOption ( uint8_t  num)

Select the option specified by index.

◆ updateFromDriverArg()

void EmbAJAXOptionSelectBase::updateFromDriverArg ( const char *  argname)
overridevirtual

override this in your derived class to allow updates to be propagated from client to server (if wanted). The implementation need not call setChanged().

Reimplemented from EmbAJAXElement.

◆ value()

const char * EmbAJAXOptionSelectBase::value ( uint8_t  which = EmbAJAXBase::Value) const
overridevirtual

const char representation of the current server side value. Must be implemented in derived class. This base class handles visibility and enabledness, only. Do call the base implementation for any "which" that is not handled in your derived class.

Reimplemented from EmbAJAXElement.

◆ valueProperty()

const char * EmbAJAXOptionSelectBase::valueProperty ( uint8_t  which = EmbAJAXBase::Value) const
overridevirtual

The JS property that will have to be set on the client. Must be implemented in derived class. This base class handles visibility and enabledness, only. Do call the base implementation for any "which" that is not handled in your derived class.

Reimplemented from EmbAJAXElement.
