[Tracking Requested - why for this release]: Search keyword feature is broken due to regression Steps to Reproduce: 1. Open RTL languages Firefox 2. Open about:preferences#search 3. Try to input/edit keyword Actual Results: Small input box appeared. But Unable to enter text. Expected Results: The input box should have a adequate width, should be able to enter text
ehsan, is this something you might look at? Or can you suggest someone who may have time to fix this? A fairly minor regression.

Sure, I'll see what I can do.
Alice0775, if you resize the window (change window width e.g.), does the text box become editable so you can enter some text? I am trying to determine if there a way to workaround this issue or not. Thanks!

Looks like I screwed up the width calculation in bug 140759...

Comment on attachment 8657227 [details] [diff] [review] Fix the width calculation of the textbox for editable XUL tree cells in RTL mode Review of attachment 8657227 [details] [diff] [review]: ----------------------------------------------------------------- ::: toolkit/content/widgets/tree.xml @@ +369,5 @@ > // in LTR mode, and left side of the cell in RTL mode. > var left, widthdiff; > if (style.direction == "rtl") { > left = cellRect.x; > + widthdiff = cellRect.x - textRect.x; I don't fully understand this. Is the X component always calculated from the top-left of the screen? That's what I see with: data:text/html,<body dir=rtl><div id="d"style="background:yellow;position:absolute; left:100px; top:100px; width:100px; height:100px;"></div></body> then running, `document.getElementById("d").getBoxQuads()` If that's the case, the widthdiff here for LTR is calculating the difference between the start of the cell and the start of the textbox. However for RTL, we would want to calculate cellRect.x + cellRect.width - textRect.x + textRect.width, which is apparently the same misunderstanding that you originally had. Can you explain why that doesn't work?

Here is a sample cell in LTR: +------------------------------------+ | | | Cell text | | | +------------------------------------+ ^..............textRect............^ ^...............cellRect.............^ Here, textRect.x - cellRect.x gives you the number of pixels that you need to subtract from cellRect.width so that the textbox's left side aligns with the left side of the cell text. Here is the same cell in RTL mode: +------------------------------------+ | | | Cell text | | | +------------------------------------+ ^..............textRect............^ ^...............cellRect.............^ I hope this picture makes it clear why cellRect.x + cellRect.width - textRect.x + textRect.width is wrong. You may ask yourself why is it that we just use one code path for computing widthdiff? The answer is that the width of the text rect is actually not computed exactly, and we guesstimate it based on the remaining width, whereas we compute our paddings properly(!), so in effect we would actually need to increase the width of the text box otherwise the rightmost text part (for example the "xt" in the RTL case above) would show from behind the textbox, so the RTL code path is designed to give you a negative number, hence increasing the width. See nsTreeBodyFrame::GetCoordsForCellItem() for the broken way in which we compute these dimensions if you're curious about the details.

Comment on attachment 8657227 [details] [diff] [review] Fix the width calculation of the textbox for editable XUL tree cells in RTL mode Approval Request Comment [Feature/regressing bug #]: This is a bit complicated. This is a bug in the XUL tree widget, which was technically introduced in bug 140759, since that is where that code was written, but before that bug XUL trees had no RTL support at all. What has made this bug visible in the new in-content preferences which is the only place in the Firefox UI where we are using this code, so this has been broken in RTL locales since the search settings was moved to the in-content preferences in bug 1106559 since Firefox 35. [User impact if declined]: See comment 0, the UI looks broken in RTL mode, and it makes editing search keyboards difficult. [Describe test coverage new/current, TreeHerder]: Tested manually. [Risks and why]: This should be very low risk. [String/UUID change made/needed]: None.
