Hide Scrollbars of InfiniteCanvas control or display thumb at the middle #4834

Open minesworld opened 1 year ago

Describe the bug

As the scrollbars visibility is set to "Auto" they might be visible for those use who told Windows via its Preferences to do so.

In that case the thumbs are always shown left and top - even after scrolling...

This is plain wrong. Either hide it by

<ScrollViewer x:Name="InfiniteCanvasScrollViewer" Grid.Row="1" HorizontalScrollBarVisibility="Hidden" HorizontalScrollMode="Enabled" VerticalScrollBarVisibility="Hidden" VerticalScrollMode="Enabled" ZoomMode="Enabled">

or rework the infinite scrolling logic so that after a scroll by using a scrollbar the thumbs are always repositioned in the middle.

Regression

7.1.2

Reproducible in sample app?

[X] This bug can be reproduced in the sample app.

Steps to reproduce

Set the scrollbar visibility in Windows to show always...

Expected behavior

Either

no scrollbars

thumbs after scrolling in the middle.

Two " load thoughts":

what is really needed is a WinUI2/3 "inifinte" ScrollBar . Whose thumb sits in the middle and moving it scrolls in the direction accellerating at the speed determined by the offset from the middle...
an InkCanvas & Toolbar in WinUI3 ... ASAP

Maybe the members of the Community Toolkit have a "shorter way" to the responsible people at Microsoft. Its a SHAME that THIS is "under consideration" https://portal.productboard.com/winappsdk/1-windows-app-sdk/c/31-inking-controls

WTF??

Now some rant (don't care about political correctnes): I bet MS is wondering why those Forms & WPF apps still don't use WinUI. Maybe they should have first targeted the UWP guys. Those were those who took the chance to make some money on the Microsoft Store AND distribute NEW KINDS of Apps using PEN input - but "payed" for that not having the full Desktop API and (even more important for me) C# & .Net language features...

With the Windows App SDK we have now that with a usable GUI instead of that Forms/WPF F*** - but NO INK! So NO new Kinds of Apps possible without doing Microsoft work...

Thats quite a recipe for success...

PS: the first Surface Studio presentation was THE reason for me after 25 years of being a "Die hard" Mac-Fanboy to buy a Surface Pro to test (!!) Windows. Now you will get my beloved Surface Studio 2 only from my cold hands... BEST computer EVER. And I had "a few" - "Hell froze over" for me: don't need Mac anymore as the Studio IS the iMac Apple never wanted to sell me.

PPS: I'm currently developing such a kind of new App. "Made for Surface"...
