<div>I'm probably in over my head here. Don't
know how to check whether <span style="font-family:monospace">(Py)Qt</span>
is compiled with freetype.<br>
<br>
Following the instructions at the bottom of the page, I did put the <span style="font-family:monospace">qt.conf</span> file shown in the
directory where <span style="font-family:monospace">python.exe</span>
resides [probably wouldn't ultimately be the optimal location for it,
but that is what <span style="font-family:monospace">QCoreApplication.applicationDirPath()</span>
returns, and it seemed the easiest thing to try first].<br>
<br>
That didn't appear to change the behavior ...<br>
<br>
At one point awhile back, I did try to make a push to migrate my code to
<span style="font-family:monospace">Qt6</span>, but there was one
piece of code I never could get to work properly. So I abandoned the
effort. :-<<br>

Thanks again!<br>

Greetings again!<br>
<br>
This is perhaps a bit of an esoteric question.<br>
<br>
I am using <span style="font-family:monospace">QFontDatabase</span>
and <span style="font-family:monospace">QFont</span> to query and
manipulate some display fonts. On my system, there are some font
family/variant combinations that have pretty long names. Several in the
<span style="font-style:italic">Bahnschrift</span> family, for
instance -- <span style="font-style:italic">Bahnschrift SemiBold
SemiCondensed,
Bahnschrift SemiLight SemiCondensed, </span>and so on.<span style="font-style:italic"></span><span style="font-style:italic"></span><br>
<br>
The Windows font settings app lists these with their full names. Also,
if I query the <span style="font-family:monospace">.ttf</span> file
directly:<br>
<br>
<span style="font-family:monospace"> path =
r'C:\Windows\fonts\bahnschrift.ttf'</span><span style="font-family:monospace"><br>
</span><span style="font-family:monospace"> font =
ttLib.TTFont(path)</span><span style="font-family:monospace"><br>
</span><span style="font-family:monospace"> for instance in
font["fvar"].instances:</span><span style="font-family:monospace"><br>
</span><span style="font-family:monospace"> style =
font["name"].getName(instance.subfamilyNameID, 3, 1, 0x409)</span><span style="font-family:monospace"><br>
</span><span style="font-family:monospace"> print(style)</span><span style="font-family:monospace"><br>
</span><br>
I get the full names.<br>
<br>
However, if I get a list of font families using <span style="font-family:monospace">QFontDatabase().families()</span>, the
names that are returned are truncated to (oddly) 31 characters. So, for
example, <span style="font-style:italic">Bahnschrift SemiBold
SemiConden, Bahnschrift SemiLight SemiConde, </span>and the like.<br>
<br>
And indeed, if I want to create a <span style="font-family:monospace">QFont</span>
object for these, I seem to need to use the truncated names:<br>
<br>
<span style="font-family:monospace">QFont('Bahnschrift SemiBold
SemiConden')</span><span style="font-family:monospace"> # These
work<br>
</span><span style="font-family:monospace">QFont('Bahnschrift
SemiLight Semi</span><span style="font-family:monospace">Conde')</span><span style="font-family:monospace"><br>
</span><br>
<span style="font-family:monospace"><span style="font-family:monospace">QFont('Bahnschrift SemiBold SemiCondensed') # These do
not</span><span style="font-family:monospace"><br>
</span><span style="font-family:monospace">QFont('Bahnschrift
SemiLight Semi</span><span style="font-family:monospace">Condensed')</span><span style="font-family:monospace"><br>
</span></span><br>
Not a <span style="font-family:monospace"><span style="font-style:italic">huge</span></span> deal, but it's a little difficult, because
the names PyQt seems to recognize aren't the ones I'd want to present to
the user (nor ones I would have thought to use, but for the fact that <span style="font-family:monospace">QFontDatabase(</span><span style="font-family:monospace">).families()</span> gave them to me that
way). Any thoughts as to why?<br>
<br>
Thanks again, as always!<br>
<br>
