How would I go about making it so that clicking the middle/wheel button on the mouse will enable the pan tool while the button is held down. (Like in AutoCAD, Map3D etc.)

Thanks,

Look for the OnMouseDown(e) and OnMouseUp(e) functions in ajaxmappane.templ

That's where all the action starts and ends.

Thanks for the reply.
I found the OnMouseDown(e) and OnMouseUp(e) functions in ajaxmappane.templ, I'm just not sure what to do with them. I'm still kind of new at this.

My Autodesk reseller is telling me it can't be done in the AJAX viewer (which is what I'm using, forgot to mention that). Does she know what she's talking about?

Thanks again,

I can't see why it could not be done.

You are basically reusing the pan behaviour which is already implemented in the AJAX viewer, you just now have to hook that behaviour to a middle mouse click and release.

Unfortuantely, I cannot show you how to implement it, because I haven't done it myself, but I do have a high-level knowledge of the internals of the AJAX viewer to tell you that such a thing is possible.

Also, resellers usually aren't programmers and/or technically minded ;-)

Jackie, you are starting to sound like Andrew D.

We are trying.

in the mousedown event, you have to check to see if it's the middle mouse button (these are different values for IE and FF...just google and you'll find this easy enough) then call the start pan function and on the mouseup, call the end pan function.

Hi all.  Was wondering if anyone had done this change successfully?  I'd really love to enable panning with mouse wheel.

many thanks

Would also like to know the solution

Hello,

Firstly, Thanks Jackie for telling everyone where to look, this was pretty easy, and I'm not great at Javascript

I tackled this, and here is what I've got working...

Looks like the placement is everything to make sure you check for middle before left/ right

In ajamappane.templ....

in OnMouseDown(e) before the check for Left Button Click, check for Middle Mouse

function OnMouseDown(e)
{
    if(!PopupMouseDown(e))
    {
        hidePopup(tbMenu);
        hidePopup(ctxMenu);
        hidePopup(infoMenu);
        parent.ForwardMouseDown(document, e);
    }
    else
        return false;

    if(!mapInit)
        return false;
        
// NEW CODE BLOCK START HERE
    if(e.which && e.which == 2) //2 is middle button in W3C/Netscape Which
	StartPanning(e);
    else if(e.button && e.button == 4) //for ie, middle button is 4
        StartPanning(e);
// END CODE BLOCK HERE FOR MIDDLE Mouse PANNING
		
     if(e.which && e.which != 1)
        return true;
    else if(e.button && e.button != 1)//for ie
        return true;

Then in OnMouseUp(e)

function OnMouseUp(e)
{       
    var x = e.clientX - mapPosX;
    var y = e.clientY;
    try
    {
        e.stopPropagation();
    }
    catch(ex)
    {
        e.cancelBubble = true;
    }

// NEW CODE ADDED HERE, BEFORE DIGITIZATION CHECK 
if(e.which && e.which == 2)   //2 is middle button
	 EndPanning(e);
    else if(e.button && e.button == 4)//for ie
       EndPanning(e);
// END NEW CODE 	   

    if(digitizing)
    {
        digitizer.MouseUp(e, x, y);
        return false;
        
    }
    
     if(isAlertShow)
        return;

I didn't test it out with other redlining or digitizing continuous commands.. ie pan will digitizing, but for my needs, just panning with the middle button adds a tonne of user experience if other things break.

Perfect!  does the trick, thankyou for posting.
