Description LeeP 2016-05-08 07:48:08 UTC 
After installing Kubuntu 16.04 LTS.
I attempted to change the font size for my KMail Message List and found that when I selected custom font and then selected KMail > Settings > Appearance > ticked Use custom fonts >  "Message List - Unread Messages" the font sizes were grayed out and not selectable. Also the same for "Message List - Important Messages", "Message List - Action Item Messages". All the "Quoted Text" settings. 

Reproducible: Always

Steps to Reproduce:
1.NA
2.NA
3.NA

Actual Results:  
NA

Expected Results:  
I should of been able to change the size of the font.

I have  the same problem with KDE 5.2.0:

Kmail Settings/Configure Kmail/Appearance/Fonts/Message List
(using Custom Fonts) will not change font size

Steps to Reproduce:

1. In Kmail, select Settings/Configure Kmail/Appearance/Fonts/Message List
(using Custom Fonts)

2. Try to change font size (various fonts)

3.  Hit Apply, OK

4. Message List font size has not changed.

  N.B. No problem changing Message Body font size.

I downgraded to kubutu 15.10 which has KDE 5.4.2 & Kmail version 4:15.08.2-0ubuntu1. It works fine.
Comment 4 Jordan Pilat 2016-05-24 15:18:25 UTC 
This happens for me as well, running KMail 5.1.3
Comment 5 Maurice Batey 2016-11-07 17:31:03 UTC 
Problem still there in KMail 5.3.0.
Comment 6 Gerd Fleischer 2016-12-08 17:14:09 UTC 
Same here with KMail 5.3.0 on OpenSuse Leap 42.2.
Comment 7 CnZhx 2016-12-19 21:57:02 UTC 
Same here with KMail 5.4.0 on openSUSE Tumbleweed.
Comment 8 Gerd Fleischer 2017-01-14 11:33:41 UTC 
Created attachment 103409 [details]
use custom font if checked
Comment 9 Gerd Fleischer 2017-01-14 11:34:31 UTC 
IMHO the problem is in themedelegate.cpp

void ThemeDelegate::generalFontChanged()
always uses system font.

Attached patch seems to fix it.
Comment 10 Maurice Batey 2017-01-14 11:57:54 UTC 
> use custom font if checked

  Problem occurred when using Custom Fonts

> Attached patch seems to fix it.

  Great news!  
Which version of Kmail will that fix be in, please?

Apply patch from Gerd Fleischer

Use custom font in KMail Messagelist if checked,
currently the systemfont is always used.

Anyone know which version of Kmail this will be applied to, please?
Comment 13 Christoph Feck 2017-02-09 22:56:10 UTC 
KMail 5.4.2, as part of KDE Applications 16.12.2 released today.
Comment 14 Maurice Batey 2017-02-10 11:31:29 UTC 
Many thanks, Christoph!
Comment 15 Maurice Batey 2017-03-12 17:33:12 UTC 
I can confirm that Kmail 5.4.3 - newly arrived in the repository for Linux Mageia-6 today - has removed this problem.
Comment 16 lnxusr 2017-04-25 16:46:10 UTC 
This is a problem for me again, Kmail 5.2.3, newly installed Kubuntu 17.04
