[Bug]: **Regression** KComboBox text is clipped; as height is incorrect.

[Smurf-IV]

Using April 2024 alpha:

Win 10 22H2 (Latest)

[Smurf-IV]

<PackageReference Include="Krypton.Toolkit.Canary" Version="80.22.11.325-beta" />:

[Smurf-IV]

I'm confused, With that much clipping, surely someone would have mentioned it as a show stopper before now !!?

[Smurf-IV]

It seems it's just the MessageBox Demo app (At the moment)

If I use the workaround mentioned here: #615
the Height is sorted, but the text is still clipped !!

[Smurf-IV]

This "Maybe" a clue.

• If I force a font into the StateCommon -> ComboBox -> Content
  • Then the size in the designer and the UI will be correct.

So the clue might be the designer (and at runtime) is picking up a null or small font for the height of the text area,
But when the text is actually drawn using the the them font, it is obviously "clipping out" due to "Not enough height"

Hi @giduac

Done, should this be for v85?

@Wagnerp
Not sure yet.

Testing this on alpha & the latest V80 release.
The results are slightly different. It's actually more prominent and/or better reproduceable in alpha atm.
Needs an extra hour of fiddling to have it all tested...

@Wagnerp,

V90 Fix (PR underway)
Itemheight is derived from Font.Height and in one accocasion (addresses in the code below) the ItemHeight = Font.Height -1
which causes the lower part of the text to become clipped.

// Working on Windows XP or earlier systems?
if (_osMajorVersion < 6)
{
	// Fudge by adding one to the font height, this gives the actual space used by the
	// combo box control to draw an individual item in the main part of the control
	ItemHeight = Font.Height + 1;
}
else
{
	// Vista performs differently depending of the use of themes...
	if (IsAppThemed)
	{
		// Fudge by subtracting 1, which ensure correct sizing of combo box main area
		//ItemHeight = Font.Height - 1;
		
		// #1455 - lower part of the text can become clipped with chars like g, y, p, etc.
		// when subtracting one from the font height. 
		ItemHeight = Font.Height;
	}
	else
	{
		// On under Vista without themes is the font height the actual height used
		// by the combo box for the space required for drawing the actual item
		ItemHeight = Font.Height;
	}
}
