New User - Window Snapping Issues

Avatar from Gravatar.com

Hi,

New user here using Windows 10, Display Fusion Pro 9.7, single 49" monitor.

I have splits setup and working OK. When I drag a window to a different split, it maximizes to that split's size.

I am trying to figure out how to get window snapping working, as outlined here: https://www.displayfusion.com/Features/WindowSnapping/

I have tried toggling the Windows snapping features on/off (in Settings -> Multitasking). This has no impact.

All I am able to do when dragging a window is have it maximize the split. I cannot get it to either snap to a monitor edge, or snap alongside another application.

Ive tried reading various threads here, but none seem to help.
Hope someone can help here.

Thanks,

Dominic

Is it this case that snapping only works within the active split?

It seems snapping works if I try to snap a window to something in the same split, but as soon as I move that window to a different split, all I can do is either maximize the window to that new split, or simply move it (maintaining its current size using the modifier key).

Is this the intended functionality?
Thanks

If you're holding the Shift key while you're dragging the window, it should snap even if you drag it to another split. There is a small catch though. You need to press and hold Shift before you start dragging. If you don't, it starts the "maximized window dragging" feature which overrides window snapping.

Hi Keith,

Im afraid I am not able to get this to work at all.
I've tried both of the following with no success:
    For a window maximized in a split, hold shift, click, and drag window to another split.
    For a window maximized in a split, click (but do not move mouse), hold shift, and drag window to another split.
Either way, the window does not snap in the new split.

Am I doing something wrong?
Thanks

I wonder if maybe we're getting our wires crossed here.

By snapping, do you mean snapping the window into alignment with the edge of a monitor or the edge of an application?

Or do you mean snapping like Windows Aero Snapping where the window resizes to half the screen?

I mean the former: snapping the window into alignment with the edge of a monitor or the edge of an application.

When I stay with a single split, all snapping works perfectly. I can drag an application to the edge of the monitor or application, and it aligns without issue.

However, when I am dragging an application from one split to another, I cannot get that application to snap to a monitor edge or application (I tried all the permutations of holding shift that I previously outlined). I have to drag the application to the new split, release, and then drag again for snapping to work.

Does that help clarify things?

Thanks for your help here.

Ok the Settings > Window Snapping tab, what's the "Snapping Mode" option set to?

Set to always snap windows.

I think I might have stumbled across some behaviors that might help narrow down what is going on.

Lets say I open a fresh instance of Notepad. It launches in windowed mode (i.e. not fully maximized). Everything snaps perfectly: I can drag it anywhere in the existing split or a different split, and it snaps to monitor edges or other application windows. Perfect!

However, I now maximize Notepad to take up the full split. When I try to drag the maximized application to another Split (all in a single mouse stroke), no snapping occurs at all (regardless of how I hold the shift key, as you outlined earlier). Perhaps this is the intended behavior? Will snapping only occur when I drag a non-maximized window?

Here's where things get tricky to describe.

When I drag the maximized application to another split in either of the following 2 ways, snapping continues to work perfectly:
    hold shift, click, and drag window to another split.
    click (but do not move mouse), hold shift, and drag window to another split.
In both scenarios, Notepad is not maximizing itself in the new split (which is to be expected given the shift key is being held). I can continue to snap the Notepad app anywhere I choose.

When I drag the maximized application to another split, not touching the shift key at all, Notepad correctly maximizes to the new split. However, when I put Notepad back to windowed mode (i.e. not fully maximized), it will never snap to any monitor edge or other application no matter what I do.

Something about dragging a currently maximized window from one split and keeping it maximized in the destination split, causes all snapping to fail once that application is put back into windowed mode. The only way I can fix this and regain snapping functionality is by closing and reopening the app.

I've spent quite some time testing and writing this post, and have replicated this issue on 2 completely different machines.

Side note: unchecking Window Management -> Show monitor selector when dragging non-maximized windows to split monitors helped me identify this issue.

Hope this detail helps. Would be grateful if you could confirm my question in the 4th paragraph and let me know if you can replicate the snapping issue.

Good find! I can reproduce the same behaviour here now as well. I believe snapping should work when dragging a maximized window as well, assuming shift is held to prevent it from re-maximizing, but I will re-test this after we have the bug (where snapping breaks after a maximized drag) fixed up.

Thanks!

Hello,

This issue should be fixed up in the latest beta, available here: https://www.displayfusion.com/Download/Beta. Please let me know if you still run into any trouble after updating.

Thanks!

Re: the other question about snapping working when you're maximized dragging. I've checked with our developers and that is currently not expected to work, just due to the way we exclude snapping in some scenarios to prevent weird window moving issues. We will be looking in to a way to make it work though, so we'll be sure to post an updated if/when we do.

Thanks!

OK thanks guys!
Very impressed with the turnaround time on this.
I will try to download this weekend and test, but I'm sure you've fixed it, given you were able to replication my issue.

Very much look forward to future progress on snapping when dragging a maximized window. Think this would be very useful.

Thanks again.
