Detailed Description

Represents a 2D grid of LEDs on a block device.

Constructor & Destructor Documentation

LEDGrid()

juce::LEDGrid::LEDGrid

(

Block &

)

~LEDGrid()

virtual juce::LEDGrid::~LEDGrid ( )

virtual

Destructor.

Member Function Documentation

getNumColumns()

virtual int juce::LEDGrid::getNumColumns ( ) const

pure virtual

Returns the number of columns in the LED grid.

getNumRows()

virtual int juce::LEDGrid::getNumRows ( ) const

pure virtual

Returns the number of rows in the LED grid.

setProgram()

virtual juce::Result juce::LEDGrid::setProgram ( Program *  )

pure virtual

Sets the Program to run on this LEDGrid.

The supplied Program's lifetime will be managed by this class, so do not use the Program in other places in your code.

getProgram()

virtual Program* juce::LEDGrid::getProgram ( ) const

pure virtual

Returns a pointer to the currently loaded program.

sendProgramEvent()

virtual void juce::LEDGrid::sendProgramEvent ( const ProgramEventMessage &  )

pure virtual

Sends a message to the currently loaded program.

To receive the message the program must provide a function called handleMessage with the following form:

void handleMessage (int param1, int param2)
{
    // Do something with the two integer parameters that the app has sent...
}

setDataByte()

virtual void juce::LEDGrid::setDataByte ( size_t  offset, uint8  value  )

pure virtual

Sets a single byte on the heap.

setDataBytes()

virtual void juce::LEDGrid::setDataBytes ( size_t  offset, const void *  data, size_t  num  )

pure virtual

Sets multiple bytes on the heap.

setDataBits()

virtual void juce::LEDGrid::setDataBits ( uint32  startBit, uint32  numBits, uint32  value  )

pure virtual

Sets multiple bits on the heap.

getDataByte()

virtual uint8 juce::LEDGrid::getDataByte ( size_t  offset )

pure virtual

Gets a byte from the heap.

setRenderer()

void juce::LEDGrid::setRenderer ( Renderer *  newRenderer )

noexcept

Set the visualiser that will create visuals for this block (nullptr for none).

Note that the LEDGrid will NOT take ownership of this object, so the caller must ensure that it doesn't get deleted while in use here.

getRenderer()

Renderer* juce::LEDGrid::getRenderer ( ) const

noexcept

Returns the visualiser currently attached to this block (nullptr for none).

Member Data Documentation

block

Block& juce::LEDGrid::block

The device that this LEDGrid belongs to.
