Fixed: Scrolling on Windows 10 tablet problem

Post by Scroller » 04 Jun 2018 11:09

There is a problem with scrolling on a Windows 10 touch screen tablet in HxD 2:

Swiping up and down on the hex editor area does not scroll, instead it selects text rather than scrolling.

With HxD 1.7.7 on a Windows 10 touch screen tablet, swiping on the Hex editor area will correctly scroll as expected.

So this is a new problem with HxD 2.0rc

Thanks for the report. However I don't have Win10 tablet to test.

Probably it has something to do with the new support for touch in newer Delphi versions.

Usually, you have to double tap to select, maybe the double click setting in Windows is too low, so it seems as if there was a bug? It could also be that you ran HxD as admin. Some extended functions are not available then, depending on your mouse/touch/etc. driver.

Either way, I would need to add some extensive logging to HxD or do a remote debug session to fix this, as mentioned above.

Scrolling with a touchpad under Win8 works fine.

P.S.: Using a fake email for privacy is fine, but if you don't check it/or check this post, that doesn't make much sense for a bug report...

Fixed in the current development version.

It was indeed a bug in the new VCL of Delphi since touch support was introduced.
The bug can be reproduced with the Windows Simulator that gets installed by Visual Studio.

Code: Select all

C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Simulator\15.0\Microsoft.Windows.Simulator.exe
This allows to use the mouse to create touch gestures (single or two-finger touch). A user of DP confirmed that it fixes the bug also under Win10/Surface 3.
