[danimo]

Our custom painting code is not RTL aware (this is with incomplete farsi translations enabled):

Also, I am not sure where the opening braces come from and why the closing brace is missing, but this may be a bug in the Farsi translations.

@danimo, @ogoffart What are the steps to reproduce the issue?

[ogoffart]

change the language to arabic or farsi and observe that everything is fine and reverted.

One can also simulate RTL language using the -reverse command line option

[Dianafg76]

@ogoffart What are all the commands to simulate RTL language?

[Dianafg76]

@ogoffart If i open the terminal and writing ./owncloud -reverse I see is as before (all the elements and all the text is left aligned)
Desktop v ownCloud-2.1.1.3022-nightly20160111.pkg

OS X: The progressbar is underlapping the [...] button and also going too far left even outside the window.
Let's try to fix this together.

[ogoffart]

So on windows it should now work. But on mac there is a problem in how the QMacStyle draw the progressbar in right to left. So it's now a platform specific issue

[guruz]

We concluded that on OS X this must be a problem with the QStyleOptionProgressBarV2 Qt OS X style (since it works when specifying -style fusion on OS X) when activating RTL.

I'd say progress bar is ok but the arrows are broken

[TheOneRing]

activity view is does not apply rtl

[TheOneRing]

The indicator pointing right is a Qt mac upstream bug, windows and fusion display it correctly

I think it would be better like this

Icons are being reversed and also the braces are from the other side (For Arabic or Persian language)

Thx for your feedback. The arrows are a mac bug in the framework we use. And the strings are probably better when using Arabic. But I can imagine our Arabic /Persian translations are pretty incomplete...
