Preferences: disable scrolling when hovering comboboxes

[ronso0]

When scrolling through preferences pages it's inevitable that the cursor hovers a combobox. Unfortunately this can cause the combobox setting to change without the user noticing, like choosing an audio device.

Let's disable the scroll capabilty of comboboxes in the preferences ui files. Maybe <FocusPolicy>Qt::StrongFocus</FocusPolicy> is sufficient already.

Any objections to ignore the scroll event on comboboxes?
If there are none I'll try to fix this.

I would only want this for the Sound Hardware page. I stumble over this fairly frequently. On other pages I'd like my scroll wheel to work as normal.

[ronso0 (ronso0)]

yeah, we need this only where
1) the pref page is long = likely to be scrolled to show hidden options
and
2) comboboxes span almost the entire width of the pref page
3) comboboxes control high-impact options (sound settings)

looks like this is true only for the sound hardware page.

So this is just a quick hack. The real problem is that the Sound Hardware page is way too long.

Exactly. No scrolling, no problem :)

We could also split all sound settings into tabs:
General | Output | Input

Hints & Diagnositics could go to the General tab, may then both Output and Input don't need to be scrolled anymore.

For 2.3 let's stick with the quick hack of disabling scrolling comboboxes in DlgPrefSound. If you want to redesign it, that's a bigger project than simply moving Hints & Diagnostics to a new tab.
