Sending values from DSP 2 GUI

This is a small addition to Jeff his online documentation on how to send (float) values from DSP to GUI.
In the SDK there is also an example, but I wanted to place it here for easy reference.


.xml file:

<Parameters>
<Parameter id="0" name="" datatype="float"/>
</Parameters>

<Audio>
<Pin id="0" name="Value In" direction="in" datatype="float"/>
<Pin id="1" name="Value Out" direction="out" datatype="float" parameterId="0" private="true"/>
</Audio>

<GUI>
<Pin id="0" name="Value In" direction="in" datatype="float" parameterId="0" private="true"/>
<Pin id="1" name="Value Out" direction="out" datatype="float"/>
</GUI>

DSP .h file:

private:
FloatInPin pinValueIn;
FloatOutPin pinValueOut;


DSP .cpp file:

dsp2gui::dsp2gui( IMpUnknown* host ) : MpBase( host )
{
// Register pins.
initializePin( 0, pinValueIn );
initializePin( 1, pinValueOut );
}

void dsp2gui::subProcess( int bufferOffset, int sampleFrames )
{
// get pointers to in/output buffers.
for( int s = sampleFrames; s > 0; --s )
{
}
}

void dsp2gui::onSetPins(void)
{
// Check which pins are updated.
if( pinValueIn.isUpdated() )
{
   pinValueOut = pinValueIn;
}

// Set processing method.
SET_PROCESS(&dsp2gui::subProcess);
}


GUI .h file:

private:
void onSetValueIn();
void onSetValueOut();

FloatGuiPin pinValueIn;
FloatGuiPin pinValueOut;

GUI .cpp file:

dsp2guiGui::dsp2guiGui( IMpUnknown* host ) : MpGuiBase(host)
{
// initialise pins.
pinValueIn.initialize( this, 0, static_cast<MpGuiBaseMemberPtr>(&dsp2guiGui::onSetValueIn) );
pinValueOut.initialize( this, 1, static_cast<MpGuiBaseMemberPtr>(&dsp2guiGui::onSetValueOut) );
}

// handle pin updates.
void dsp2guiGui::onSetValueIn()
{
// pinValueIn changed
pinValueOut = pinValueIn;
}

void dsp2guiGui::onSetValueOut()
{
}
