477590 - [Mac] Search widgets look wrong in RTL mode

Status: VERIFIED FIXED

(Core :: Widget: Cocoa, defect)

Attachment: Screenshot of searchfield in RTL mode

See bug 450800 comment 41 and 43: In RTL mode, both the search icon and the cancel button are on the left.
We should either draw the search icon at the logical start or lock the cancel button at the right.

The former would be the ideal fix. The latter would be workaround, and while it would make the search field look balanced, I'm not sure if a cancel/clear button at the logical start makes sense interaction-wise.

Similar things can also be seen for rtl locales on Windows. The clear icon isn't shown at all. Markus, shall I better file a new bug on that? I think so because we are using a native widget on OS X.

Markus, would you have time to fix it for FF3.1?

This patch implements the former approach.  I haven't tested it myself though.  Could someone with a Mac please test it?

That patch is wrong in several ways. You're adding the padding on the wrong side; the search icon is internally still drawn on the left. And you're flipping the whole textbox, including the clear icon and the text content.

How come?  The right padding should be -moz-padding-end and the left padding should be -moz-padding-start, right?

> the search icon is internally still drawn on the left.

Hmm, does scaleX(-1) affect the paddings as well?  I was assuming that it doesn't...

Oops.  That should be corrected by specifying scaleX(1) on the textbox-input-box hbox, right?

It takes the whole thing and draws it mirrored.

textbox-input-box is right, but scaleX(1) would be a no-op.

Ehsan, may I take this bug? Sorry that I didn't get to it earlier.
I'm working on a patch that doesn't need additional CSS styles and instead mirrors the control in nsNativeThemeCocoa.mm.

I haven't tested it on 10.4, but this should be relatively complete.

Sure, what you're doing is much better. :-)

Attachment: screenshot with patch

With the patch, all controls that we draw with NSCells will be mirrored for RTL frames, even dropdowns and checkboxes. Is that the right thing to do?

Probably not.  I'm not familiar with RTL conventions on Mac, but at least on Linux and Windows, some controls are mirrored in this way (like drop-downs for example), but things like checkboxes do not get mirrored.

I think you need to check what other RTL apps on Mac do...

I have no idea how to do that. I've tried selecting different RTL languages in the System International preferences, but that didn't change anything, probably because those languages aren't supported by any app that I tested. And AFAICT there's no RTL language among the ones that Mac OS X supports natively:

Yehuda, you've done Mac RTL stuff before, can you help us out?

This is correct. Apple does not supply out-of-the-box support for RTL languages. Support for Hebrew is developed and distributed separately by iDigital - the local Apple distributor. There might be similar packages for Arabic and Farsi.

I never installed this package because: 
A. It looks like a Beta - with many elements still drawn the wrong way. (e.g. the folders on the left in Mail and Finder as seen in this screen-shot: http://skitch.com/ziv_kitaro/i16i/1)
B. I'm too used to the LTR layout.

From looking at the screen-shots around the net, it looks like some of the controls are mirrored and some are not. Ehsan is right about the checkbox. It looks wrong when mirrored.

Sure. Let me know if you need anything else.

Indeed, see http://www.emiratesmac.com/forums/blog/5090-arabic-leopard-out.html for Arabic.

IB3 on 10.5 supposedly supports a RTL pop-up button widget, but I've never been able to coax it into appearing, so I assume no native apps are using it (Mellel, at least, does not appear to, though I think it still supports 10.4, anyway).

IMO, the pop-up button and combobox controls probably make the most sense to flip, since right-aligned text flush up against the blue endcap just looks "wrong" to me (regular buttons you flip, of course, but since they're symmetrical, they're not noticeable).  But my rule has generally been "what does Mellel do?" ;)

Based on the comments posted here, I think we need a new patch which doesn't flip checkboxes but continues to flip drop-downs.

Tryserver told me that the searchfield-mirrored-when-rtl.xul test fails on both Windows and Linux, so I've enabled it only for Mac.

You need to update your tree and merge in textbox.css.

We should probably take this on branch, because of the rtl improvements and because it makes it easier for themes to use -moz-appearance: searchfield, which has been introduced in beta 3.

The search icon in the search bar is still a bit mis-aligned. I'll file a new bug on this issue.
