-
- In addition to sending button pressed and button released events, ControlButton objects can allow your application code to change the colour of the LED behind the corresponding physical button on a BLOCKS device.
-
- An array of pointers to the available %ControlButton objects can be obtained from the Block::getButtons method of a Block---see the @ref discovering_blocks section for details of how to obtain a %Block object.
- Once you have a %ControlButton, the functions involving the LED are ControlButton::hasLight and ControlButton::setLightColour, which are descriptively named.
- A code snippet showing how to turn all the available buttons of a %Block red is shown below.
- @code{.cpp}
- void setAllButtonsRed (Block& block)
- {
- for (auto button : block->getButtons())
- if (button->hasLight())
- button->setLightColour (Colours::red);
- }
- @endcode
