Description sdc.blanco 2020-02-05 12:47:10 UTC
There is no transparency control in the "font effects" tab for Writer Paragraph Style and Character Style dialogs.

In Writer, Format>Character-Font Effects tab has a transparency control.

For the other modules (Calc, Draw, Impress), all "font effects" tab (also for styles) have a transparency control.

Bug or not?

I believe https://gerrit.libreoffice.org/plugins/gitiles/core/+diff/6d6e80435fd7f71342c429a67759a7b7b280cc55%5E%21 does what you ask for, does it?
Comment 2 Miklos Vajna 2020-02-18 11:19:48 UTC
Ah, confirmed, direct formatting has it, the Style versions don't. Could be added, indeed.
Comment 3 Heiko Tietze 2020-02-19 12:40:18 UTC
Cool stuff. But please follow the guidelines for property dialogs https://wiki.documentfoundation.org/Design/Guidelines/PropertyDialog (labels are left-aligned -> https://gerrit.libreoffice.org/c/core/+/89017). 

No need for input from UX, character dialog is done, paragraph style missing.

@Miklos - I was going to try, but I cannot figure out why it is not already being shown.  

- assume Paragraph Style and Character Style also use effectpage.ui
- which is controlled with cui/source/tabpages/chardlg.cxx  
- where the relevant place to hide the transparency controls is: 


- assume problem is that "Paragraph Style" and "Character Style" are not passing the needed flag 

- but cannot see where the flags for Paragraph and Character Style are defined. 
Do you happen to have information about that?
Comment 5 Miklos Vajna 2020-02-21 08:51:34 UTC
Not off the top of my head; the usual approach is to put a breakpoint to the place where the chardlg is created (perhaps the SvxCharEffectsPage ctor) and then see the backtrace in the debugger. I hope that will give you the place where you indeed probably just need to opt in by specifying SVX_ENABLE_CHAR_TRANSPARENCY.
