Use system-consistent icon sizing.

[RokeJulianLockhart]

The current iconography is unnecessarily large:

• Could this be related to #63?
• Does it involve a High DPI desktop or a normal one?

[digitaltrails]

In #63 I added a setting to try and help adjust icons appropriately according to DPI. However, I've never be sure if what I've done is the right approach.

It now occurs to me that the choice of icon sizes might be more accurately determined by interrogating the default font size in use.

I've had to play similar games in the past. To detect a dark/light theme I create some text in a QLabel and test the relationship between the text and background colors. In this instance could extract a QLabel's font size (in a relevant metric) and base icon sizes around that.

@digitaltrails, https://www.infobyip.com/detectmonitordpi.php states 96×96 DPI. I use a 1440p monitor.

"After" at https://github.com/digitaltrails/vdu_controls/issues/63#issuecomment-1734675375 is (more like) what I expected.

In the settings dialog, try turning off the adjust for dpi setting (it will prompt to restart the app).

I think the following code might be returning True:

def is_high_dpi() -> bool:
    return adjust_for_dpi and QApplication.primaryScreen().physicalDotsPerInch() >= 160

I'll have to add some logging to see for sure.

I've not been able to locate it, @digitaltrails. Could you screenshot the window you refer to?

[RokeJulianLockhart]

@digitaltrails, mine is different – that option is absent.

[digitaltrails]

Oh, it's a new option in v.12.0, you'd need to probably download the vdu_controls.py from github and replace the version you're using - or wait for the distribution to catch up.

I thought I'd released in in v1.11, but no v1.12 only got released yesterday.
