UltimateListCtrl with a custom renderer should probably do the trick. I believe the demo has something similar.

Hi Andrea,
I've looked at the UltimateListCtrl demo, and have Googled it a bit, but I see no examples in which a =single= item can have multiple colors, as in my black-and-red and black-and-green examples below.
I need to be able to present, in a list control, vocabulary items which contain specific character strings, with those character strings highlighted.
You've created a lot of very useful controls. If what I need does not yet exist, might you be able to create what's needed? Presumably as a mod to UltimateListControl, or a mix-in, rather than a new control.

There is, in the demo. If you look at the UltimateReportDemo.py, there are a few lines of code like:
randomRenderer = random.randint(0, 2)
if randomRenderer == 2:
# set some custom renderers...
klass = UltimateRenderer_1(self)
renderers[index] = klass
self.list.SetItemCustomRenderer(index, 3, klass)
elif randomRenderer == 1:
klass = UltimateRenderer_2(self)
self.list.SetItemCustomRenderer(index, 3, klass)
else:
klass = UltimateRenderer_3()
self.list.SetItemCustomRenderer(index, 3, klass)
UltimateRenderer_2 is the class you want. Looking at how that class implements its DrawSubItem method:
def DrawSubItem(self, dc, rect, line, highlighted, enabled):
dc.SetBackgroundMode(wx.SOLID)
dc.SetBrush(wx.Brush(wx.BLACK, wx.SOLID))
dc.SetPen(wx.TRANSPARENT_PEN)
dc.DrawRectangleRect(rect)
dc.SetBackgroundMode(wx.TRANSPARENT) dc.SetFont(self.randomFont)
colours = [wx.RED, wx.WHITE, wx.GREEN, wx.NamedColour(“SKY BLUE”)]
w, h = dc.GetTextExtent(“Hg”)
x = rect.x + 1
y = rect.y + rect.height/2 - h/2
for ch in self.text:
dc.SetTextForeground(random.choice(colours))
dc.DrawText(ch, x, y)
w, h = dc.GetTextExtent(ch)
x = x + w
if x > rect.right - 5:
break
You can easily see that, for each character in the string “self.text” it chooses a random color and draws that letter. I believe it would be quite easy to modify that class to do what you want.

</details>Thank you very much, Andrea! The copy of the UltimateListCtrl demo I have is quite old, and the super-helpful code you've just cited is not part of it. I'd like to install the current demo package on my new 64-bit machine, but I haven't yet figure out how to do so. Rightly or wrongly, I'm afraid to try running the 32-bit installer, wxPython3.0-win32-docs-demos.exe, the only installer listed at Redirecting... . Is my "fear" unfounded?

Thank you very much, Andrea! The copy of the UltimateListCtrl demo I have

It is. The 32-bit installer for the demo works without issues on any
Windows architecture. As Mike (and quite a few others) said, the installer
simply creates a few folders in the path you choose and copies there the
demo files (which are Python files). No risk whatsoever.
Andrea.
