Hi all I found no evidence of fontconfig not being working properly in my system. so I've made a small test instead of setting font family to null string I've set it to a bogus name. f.setFamily( "BOUGUSTRASHFAMILY" ); // no family name, forcing Qt to find an appropriate font by itself and in x01c example as there are four plots i edited the source to add the plfont(1); before plot 1, plfont(2); before plot 2, plfont(3); before plot 3, plfont(4); before plot 4, I also get erase the esc text sequence that put title always in Roman. The results are what one would expected.
Hi António: I agree, that one-line change seems to have solved all qt device driver issues on your platform. So I tried the equivalent here, and it solves some less obvious Qt issues here for examples 23 and 24 that have been around for quite a while. So congratulations on finding a solution to a PLplot qt device driver bug that has apparently been around since the very first development of that device! I commited a small variation (I added commentary and I replaced your bogus family name because it was [barely] conceivable a valid font might adopt that family name) of your fix as of plplot-5.14.0-8-gdb9d90d0b. So please test that commit (by using git checkout plplot-5.14.0-8-gdb9d90d0b before building PLplot from the git version) to make sure it answers all your qt device needs (other than character size). @Everybody: This fix is pretty crucial for our qt device driver because it appears to fix all long-standing font problems (including character alignment for António) for that device driver. Therefore, I intend to release 5.14.1 with this fix and any other critical fixes that show up in the next few weeks. More about the git process I should use to create a bug-fix release (such as the proposed 5.14.1) in my next post. Alan __________________________ Alan W.
