Bug 43530 – LyX won't display symbols in math functions properly (such as Omega, pi, etc.), after upgrading Qt to 3.3.1 from 3.3.0-r1.

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description James Ravn 2004-03-02 15:13:41 UTC]

This is reproducible in both LyX 1.3.3 and LyX 1.3.4.  Other versions have not been tested.  After upgrading to Qt 3.3.1 from Qt 3.3.0-r1, any special symbol within a math function is not displayed properly. For example, the Omega symbol gets replaced with a dash and pi gets replaced with a '1/2' character.  Downgrading to 3.3.0-r1 fixes the problem.

Reproducible: Always
Steps to Reproduce:
1.emerge x11-libs/qt-3.3.1
2.USE="qt" emerge app-office/lyx-1.3.3 OR emerge app-office/lyx-1.3.4
3.try adding a math symbol, aka \Omega into a LyX math function. it won't be displayed properly!
4.emerge -C x11-libs/qt-3.3.1 && emerge x11-libs/qt-3.3.0-r1
5.try adding a math symbol into LyX now. it works.

Actual Results:  
First the math symbols don't display properly (qt 3.3.1), then they do (qt
3.3.0-r1).

Expected Results:  
Math symbols should be displayed properly in Qt 3.3.1 w/ LyX qt-frontend.

caleb: do you have any idea about it?

[Comment 2 Caleb Tennis (RETIRED) 2004-05-07 12:05:15 UTC]

Not sure.  Font handling in qt 3.3 has been changed.  it may be worthwhile to try out 3.3.2 and see if the problem has been fixed there.

Thanks. I'll give it a try then. Will report about it tomorrow ;)

[Comment 4 Mamoru KOMACHI (RETIRED) 2004-05-08 00:55:45 UTC]

Right. Thanks for the hint. This problem is fixed in qt-3.3.2. I
tried lyx-1.3.4 with several versions of toolkits.

symbols are rendered correctly: xforms-1.0, qt-3.3.0-r1, qt-3.3.2
symbols are not rendered correctly: qt-3.2.3-r1, qt-3.3.1-r1

James, please upgrade qt to 3.3.2 and see if the problem is fixed.
