Hi James & Max - here's how to enable Mac trackpad multi-touch navigation in the node editor when the next MoI beta is out. These are all in the file main.js

Inside LGraphCanvas.prototype.bindEvents add this:

	this._trackpadgesture_callback = this.bindFunction(this.trackpadHandler, this);
	canvas.addEventListener("trackpadgesture", this._trackpadgesture_callback, true);

Inside LGraphCanvas.prototype.unbindEvents add this:

	this.canvas.removeEventListener("trackpadggesture", this.trackpadHandler );

Then add this function:

LGraphCanvas.prototype.trackpadHandler = function(e)
{
	if(!this.graph || !this.allow_dragcanvas || this.selection_mode) return;

	if ( e.gestureType == 'Zoom' )
	{
		// Pinch gesture.

		var speed = 2.0;

		var factor = 1.0 + (e.scaleFactor * speed);
		var newscale = this.scale * factor;

		if ( newscale > 0.0 )
		{
			this.adjustMouseEvent(e);

			this.setZoom( newscale, [ e.localX, e.localY ] );
			this.graph.sendActionToCanvas("setDirty",[true,true]);
		}	
	}
	else if ( e.gestureType == 'Scroll' )
	{
		// 2 fingers scroll gesture.

		// If Ctrl is down, return without calling event.preventDefault() so
		// a mouse wheel event will be triggered.
		if ( e.ctrlKey )
			return;

		var speed = 1.0;
		
		this.offset[0] += (e.deltaX * speed) / this.scale;
		this.offset[1] += (e.deltaY * speed) / this.scale;
		this.graph.sendActionToCanvas("setDirty",[true,true]);

		// Note: don't set this.canvas_moved = true; like right mouse drag uses because
		// it's used to disable context menus if the right mouse was dragged instead
		// of clicked. If we set it here it makes context menus hard to launch.
	}
	else if ( e.gestureType == 'SmartZoom' )
	{
		// 2 finger double tap, use for zoom extents / reset view.

		// TODO

	}
	
	e.preventDefault();
}

Hi Michael,

thank you! I'll add this code to the next version of Nodeeditor.

P.S. Today I bought a trackpad, so I will add full support of multitouch navigation.

Nodeeditor 1.0 release candidate 2

Added: Multiple start parameters support (example: moi://appdata/nodeeditor/index.html?scheme=Light&somethingelse=123)
Added: You can open second Nodeeditor window by pressing Alt + New button
Added: Nodeeditor doesn't flush clipboard data on window close
Added: Initial Trackpad support (New zoom engine should work fine with all v3/v4 MoI versions. Also I made changes in Knob and Slider nodes. Let's hope I didn't break anything ;))
Added: Some visual improvements

French version with the French lang.js with quasi all "deviant" ELephant ! :)

Can you detail the open second Nodeeditor window by pressing "Alt + New button" ?

Say I have N shortcut for the first window Editor : what is "Alt + New Buton" ? ( a new shortcut ? ...

My first ShortCut for N is
moi.ui.createDialog( 'nodeeditor/index.html', 'resizeable,defaultWidth:680,defaultHeight:420', moi.ui.mainWindow )

what is the second ?

say i have B for second same ShortCut
moi.ui.createDialog( 'nodeeditor/index.html', 'resizeable,defaultWidth:680,defaultHeight:420', moi.ui.mainWindow )

Say first window open by N

Press B or Alt + B gives nothing! :)

WOW!!!

Thank you very much Max!!

I'll try it soon.

Ciao!

Great stuff Max,

Zoom functions much better now with trackpad.

Thanks for your continued development
James

P.S. Double tap to zoom to extents is the last piece in the puzzle

---

Hi James,

As Michael wrote above, he will add a trackpad gestures support to the next MoI beta.
Then I'll add pinch/zoom, two-finger scroll, double tap gestures to Nodeeditor.

Hi Max,
I'm getting this type of display on my Surface Pro 4 of latest nodeeditor.
I don't think this is correct and maybe a resolution issue ?

Hi Barry

Yes, it's HiDPI mode issue.
Yesterday I also noticed this bug when I run MoI v4+Win7 on my Mac using a virtualization software. So I can reproduce it.
In the same time it works good on Win10.

About the second button for the nodeeditor ?
http://moi3d.com/forum/index.php?webtag=MOI&msg=7713.794

---

Hi Pilou,

press Alt button on keyboard and click on "New"/"Nouveau" button on screen (upper left corner of NE window)

---

Perfect! Works like a charm!
Bravo!

---

Hi Barry
I fixed this bug. Here is updated version: http://moi.maxsm.net/nodeeditor/nodeeditor.v.1.0.rc2b.2018.02.11.zip

---

About the "Second Window"

I am wrong or seems we can Open any number of new windows of the NE ?

---

Another small update:
Added: mac trackpad gestures support
Added: macros directory (put often-used macros to this directory)

Hi Max,
thanks works great.

Hi Max

Thank you for the update:

> Added: mac trackpad gestures support

Pinching to zoom works just as it should! Great work.

However double finger, double tap does not "zoom to extents" as expected.
Rather it zooms to mid-size, but does not centre on the canvas.

Nevertheless it is a vast improvement
Thanks again

James

I'll change the double-tap zoom logic in the next release.

nodeeditor.v.1.0.rc3 (I hope this one will be last before v1.0 release)
http://moi.maxsm.net/files/nodeeditor/nodeeditor.v.1.0.rc3.2018.03.09.zip

Fixed a couple of bugs.
Also I clean all waste from NE files.
Updated translation file.

Pilou, I removed french translations of all obsolete and unofficial nodes. Later I will help you to make an extension for unofficial nodes.
Right now I need your help with translation. Could you check an attached file, and add translations for all words marked with "?"

---

sure! ;)
