ofxPointer
Description
This frameworks adapts the W3C Pointer Event specification to work with openFrameworks. A compatibility layer for iOS / UITouch
includes support for high-frequency coalesced events, predicted events, event property updates, tilt, pressure and other advanced properties.
Features
Currently the openFrameworks pointer model separates touch and mouse events, making cross platform development a little tricky.
Simply put, ofxPointer
merges pointer, touch and pen input into a single extensible interface.
A typical program will now look like this:
All Platforms
#pragma once
#include "ofMain.h"
#include "ofxPointer.h"
class ofApp: public ofBaseApp
{
public:
void setup() override
{
// Register the pointer events.
ofx::RegisterPointerEvents(this);
}
void update() override
{
// Update
}
void draw() override
{
// Draw
}
void onPointerUp(ofx::PointerEventArgs& evt)
{
ofLogNotice("ofApp::onPointerUp") << evt;
}
void onPointerDown(ofx::PointerEventArgs& evt)
{
ofLogNotice("ofApp::onPointerDown") << evt;
}
void pointerMove(ofx::PointerEventArgs& evt)
{
ofLogNotice("ofApp::onPointerMove") << evt;
}
void onPointerCancel(ofx::PointerEventArgs& evt)
{
ofLogNotice("ofApp::onPointerCancel") << evt;
}
};
Or even more simply, like this:
#pragma once
#include "ofMain.h"
#include "ofxPointer.h"
class ofApp: public ofBaseApp
{
public:
void setup() override
{
// Register the pointer events.
ofx::RegisterPointerEvent(this);
}
void update() override
{
// Update
}
void draw() override
{
// Draw
}
// All pointer events are returned to a single callback.
void onPointerEvent(ofx::PointerEventArgs& evt)
{
ofLogNotice("ofApp::onPointerEvent") << evt;
}
};
iOS
iOS Currently supports all advanced UITouch
features including tiltX/Y, elevation, azimuth, precise location, pressure, predicted and coalesced events, estimated properties and estimated property updates. See the iOS examples for more.

Some past openFrameworks releases are supported via tagged versions, but only stable
and master
branches are actively supported.
