[Question/Feature Request]: Drop Down Arrows sizing query

[MattH-Work]

With the latest February 2025 toolkit, drop down arrows have changed

Originally

Now

What is the reason?
Can they be modified?

Hi @MattH-Work

Please see #1211. The reason was that the older type did not resize with the controls, or adjusted with theme colours, as it was a png image. Yes you can now adjust the colours.

"Yes you can now adjust the colours"
Could you give me a quick hint on how to do this?

Is there a way to make the triangle a little more subtle ( i.e smaller )

Hi @MattH-Work

While you can't change the size (yet), the colours use the same colour property as the text.

@Smurf-IV Is this the same for KComboBoxes?

I think so (I think I did them all apart from the up / downers)

Please revert to the original (smaller) arrow or use a more subtle one like the one in WinForms controls. This one is very distracting 😅

@Smurf-IV Is there a way to make them smaller? I don't think that we should revert back to using images, as this would cause issues for DPI scaling.

Yes, Currently based on 2/3 height, as this seemed to be the best when the font is large.
(Note: even win 11 arrows are fatter !)

Agreed: Amongst other things

@Smurf-IV

Where is the drop-down drawing located?

Testing the colors in a KCustomPaletteBase, the arrow's appearance becomes smaller if you set color1 to the same as the button's background, you only need to do this for all states (normal, pressed, tracking...).

@lesandrog
That makes sense, because colr1 is the outer outline colour. so if it the same as the background it would "appear" to be smaller
