Bug 103412

I could confirm it is very difficult to get the menu of "font color" and "background color" in conditional formatting.

To reproduce:
Open a database-file.
Goto reports and create a report without assistant.
Create a textfield without connection to any table.
Goto Format > Conditional Formatting
Try to choose "font color" or "background color" from a palette.
Most of the trials won't work. I had luck when pointing to the upper right corner of the button.

My system: OpenSUSE 42.1 64bit rpm Linux, LO 5.2.2.2

Have tested a little bit more.
Works right with LO 5.0.5.2
Fails since LO 5.1.*
So a regression.

The GUI changed with the same version. Could be it is a special LO KDE-bug. I will see this later.

Have tested this with
Version: 5.3.0.0.alpha1
Build ID: f4ca1573fcf445164c068c1046ab5d084e1b005f
CPU Threads: 4; OS Version: Linux 4.1; UI Render: default; VCL: kde4; 
Locale: de-DE (de_DE.UTF-8); Calc: group

First I doesn't install the KDE-integration package. Then I opened a report, marked a textfield and satated 
Format > Conditional Formatting
I could choose "Font Color" and "Background Color" without any problem.

Then I installed KDE-integration. The icon-style changed to Breeze.
With this installation I couldn't choose "Font Color" and "Background Color".

This bug seems to be a special KDE-integration bug and is independent of the version of LO.

Created attachment 128185 [details]
Database with only a report and an empty textbox.

Open the attached database.
Open the report for editing.
Mark the textbox.
Open Format > Condition Formatting.
Try to choose Background-Color or Font-Color.
Won't work, if KDE-integration is installed under
OpenSUSE 42.1 64bit rpm Linux KDE Plasma Version 5.5.5, specially tested here with the first 5.3.0.0.alpha1
Build ID: f4ca1573fcf445164c068c1046ab5d084e1b005f

Works with this version, if KDE-integration isn't installed.

On pc Debian x86-64 with kde4 rendering on master sources updated today or with LO Debian package 5.3.4, I don't reproduce this.

Robert/Matteo: could you give it a try with a recent LO version?

Julien: I'm sorry, but I don't use Ubuntu anymore, so I won't be able to test it.

Could confirm it is working now with
Version: 5.3.5.1
Build-ID: 020db1aa8142e57290f8a21e4df31185392d0e38
CPU-Threads: 4; BS-Version: Linux 4.4; UI-Render: Standard; VCL: kde4; Layout-Engine: neu;

(OpenSUSE 42.2 64bit rpm Linux)

Set this one to RESOLVED and WORKSFORME.
