In some apps (uwp?) three fingers to drag doesn't work

[k-kruglov]

I suppose it might be related to these apps being UWP, I've tried with Unigram (telegram client) and RSS tracker https://apps.microsoft.com/store/detail/rss-tracker/9N85PV1RJD6V?hl=en-us&gl=US or system settings app.

In all of them the standard text selection works (click + drag), when your app provided 3 fingers to drag doesn't.

Surface Book 1, windows 11.

p.s.

As also a mac user, I nearly started crying when I found out about your app on Reddit. I'm so used to this accessibility feature on macs, and switching to Windows was painful every time.

For moving and pressing the left click, I use the function mouse_event from user32.dll, which effectively do not work in UWP applications.

I'll have to update the code a bit to make it work with UWP apps, using input injection.

Thanks for the report !

Sounds that this is possible after all, which is great!

Can confirm that this does not work on multitasking view. I suppose it's because of the same reason?

I'm afraid I will not be able to update this app anymore.

I developed it in three days when I had a Windows laptop, but I don't have it anymore, and I figured out I had no wireless trackpad at home.

I hope someone will be able to fork this app to add the UWP support and fix some other bugs. Thank you !

FYI: Some of apps' windows are also not able to be dragged.

• Microsoft PowerPoint
• Slack

Hi @k-kruglov, @MasaYan24, @lynnrinkui, I used this project as inspiration to write my own version, if you feel like, please try my version which I believe fixes all the issues you mention. https://github.com/gurinderhans/threefingerdrag

@ClementGre, this is an amazing project, if you choose to, you can incorporate the fixes into your project :)

Hi, I just got a Windows laptop to work again on this project.

Thank you @gurinderhans, your app is amazing and fixes a lot of issues. I inspired myself of your code to fix issues in ThreeFingersDragOnWindows. I do will not copy all of your code, but I'll try to fix these issues by looking at your code.

For this issue, I can't reproduce the bug on PowerPoint or in the system preferences, but I do can in the Win + Tab menu.

I was able to fix this issue by using input injection, from user32.dll (just like @gurinderhans did) :

For moving and pressing the left click, I use the function mouse_event from user32.dll, which effectively do not work in UWP applications.

I'll have to update the code a bit to make it work with UWP apps, using input injection.

Then I guess this issue will not be present in the next release !

The program works fine on most UWP apps, such as

Microsoft Store and Microsoft PowerPoint

But on Windows 11 22631.3672, I can't drag files in File Explorer I hope someone will fix this problem.

Hi @michaelliunsky, can you reproduce the issue with TFDOW started with elevated privilege (as administrator)?

Hi @michaelliunsky, can you reproduce the issue with TFDOW started with elevated privilege (as administrator)?

I solved the problem by accident by turning off my antivirus software. I think it may be the anti-virus software that blocks the normal operation of the program.
