Hello!
I’m watching a scrolling in standard combobox and see same behavior (several items are scrolled by one mousewheel tick) in your Exe. What is difference there?

Sorry, I did not point out the problem clearly:

When You click in a TComboBox and move the mouse-wheel a single tick, the selected item of the TComboBox changes to the next one in the list (ItemIndex changes by +/- 1).
When You do the same with a TsComboBox, ItemIndex changes by +/- n.
I did some further testing an found out, that n seems to depend on the number of Parents of the TsCombobox.

I modified the demo and placed several combo boxes on different parents:
TForm->TsCombobox: ItemIndex changes by 2
TForm->TsPanel->TsCombobox: ItemIndex changes by 3
TForm->TsPanel->TsGroupBox->TsCombobox: ItemIndex changes by 4
All TCombobox: ItemIndex always changes by 1

The TsComboBox of the MegaDemo behaves the same way as the TComboBoxes in my demo.

I used AC 16.17 with Dlphi XE3 Update 2 on a Windows 20H2 for testing.

Thank you for a project. Could you give me the Exe file also, please?
Can’t say why, but I have another behavior of the program after compiling.
I want to compare them.

Thank You looking into it!

Attached are two compiled exe, one with “Debug”, one with “Release” configuration as set up in the demo.
Not sure wich one suits Your needs.
