It was never in the window. It can be found in the context menu (right-mouse-button menu).

[Oliver (schrodingersgat)]

I'm fairly confident it was - at least prior to the large refactor that has happened since the 5.x release.

I used to use this feature all the time - it was handy to be able to zoom using the mouse wheel while aligning a 3D model with a footprint.

[Jeff Young (jeyjey)]

@Oliver, mousewheel zoom is different. That's controlled by Preferences > Common > Use touchpad to pan. (You want it to be off for mousewheel or touchpad zooming; on for mousewheel or touchpad panning.)

Hi Oliver-

I think perhaps you are thinking of the 3d viewer.

Here's an image from 2016 (http://kicad-pcb.org/img/post/footprint_3dpreview.png). It looks pretty much like what I see on 5.0.1-dev

[Oliver (schrodingersgat)]

Here's what it looks like for me:

In this window, mouse-wheel-zoom does not work independent of the state of the "use touchpad to pan" setting.

[Seth Hillbrand (sethh)]

Yes, that looks like the current setting. Does the wheel do anything for you? When I have touchpad to pan enabled, the wheel moves it up/down and I need to use Control+Wheel to zoom in/out. When the option is disabled, mine zooms without ctrl.

Maybe a windows issue? Anyone else on Windows seeing this?

[Oliver (schrodingersgat)]

The scroll-wheel does nothing, and it is not altered by the "use touchpad to pan" setting.

I confirm (at least on W7) the mouse wheel behavior is broken in 3D preview panel:

in 5.01 it is OK: mouse wheel = zoom in/out mouse wheel + Ctrl/Shift = Pan.

in 6.0 it is broken: mouse wheel does not work.

Moreover when opening the footprint dialog 3D tab, mouse wheel + Ctrl/Shift do something, but once an other widget has the focus, the 3D preview panel never get the focus when clicking on it and ignore all mouse wheel commands.

[Jeff Young (jeyjey)]

Ah crap. This sounds like a result of the steals focus bug.

In 5.0 when you click in a textctrl in the 3D preview in the Footprint Properties dialog and then move the mouse over the 3D canvas, the focus is lost from the textctrl. I fixed that by having the canvas not steal focus on mouse enter, but probably at the expense of this.

Is there some (straight-forward) way to have the dialog pass the wheel/touchpad events on to the 3D view?

[Wayne Stambaugh (stambaughw)]

I am not having this issue. Does the 3D model view mouse zoom behavior work correctly after clicking on (selecting) the view panel? I saw a similar issue with the footprint viewer in the symbol chooser dialog a long time ago. It doesn't do this any more. I'm not sure what changed although I did replace my mouse and bluetooth adaptor so maybe it's driver related.

[jean-pierre charras (jp-charras)]

On my W7 install, when left clicking on the 3D model panel preview, it never get the focus, so the mouse wheel and hotkeys never work.
(the other widgets that has the focus always receives the mouse wheel and key events)

However, some mouse events are working: right button click (the context menu is shown), and left and middle buttons drag works.

[Oliver (schrodingersgat)]

Jeff,

From a user perspective if the mouse is over the 3D model I would expect that a scroll wheel event would zoom the model, rather than changing the values in the most recently selected entry box. So it does sound like a focus issue as you say.

[jean-pierre charras (jp-charras)]

Looks like this is a Windows specific issue.
