Mouse wheel scrolling rate is very slow in Split Transactions dialog

[tactilis]

MMEX version:

• 1.6.1
• 1.6.2 Alpha

Operating System:

• Windows
• Mac OSX
• Linux

Description of the bug

Using the mouse wheel to scroll the Split Transactions dialog is very slow compared to scrolling in all other parts of MMEX and in all other applications I use.

Reproduction

Reproduction steps:

1. Add sufficient rows on the Split Transactions dialog to require scrolling to view them all.
2. Scroll up or down using the mouse wheel. Observe that the scrolling rate is unexpectedly and unreasonably slow.

For comparison, here are two screen recordings:

1. Scrolling in the Split Transaction dialog; firstly using the scroll bar and then using the mouse wheel, spinning it as fast as possible.
2. Scrolling in the Organize Categories dialog using the mouse wheel.

I can't reproduce that lag under MacOS or Win11. E.g on Win11

OK. Interesting.

What setting do you have for Lines to scroll at a time please?

As you can see, I have it set to 3, which is perfect for other apps and for other scrolling in MMEX - but not for Spilt Transactions. This video demonstrates the effect of turning the mouse wheel one 'notch' at a time. The scroll step on this particular dialog is tiny; it takes 12 wheel 'notches' to scroll one complete Split row.

I observe the same 12 steps to scroll one Split row if I use may laptop's trackpad instead of the mouse or if I use a different brand of mouse.

If I increase Lines to scroll at a time to, say 40, then close and restart MMEX, the Spilt Transactions dialog scrolls at a more reasonable rate (but is a bit jerky due to the larger steps) - but everywhere else scrolls too fast.

My settings are identical to yours.

Yes, same for me if I scroll notch-by-notch.

See if above change helps.

SetScrollRate(6, 6);

Perfect. That makes scrolling comfortable.

Not that I ever have transactions with lots of splits - but we've seen that some people do, so this should help them.

The MMEX Options dialog has the same slow scroll rate. Scrolling is often needed in that dialog if View | Font size is set to Large or Huge.

Could the same SetScrollRate fix be applied please?

Thanks. All good now:

• Split Transactions
• Options
• Custom Fields
