[webkit-dev] how to write layout test to test mouse wheeling on document

Webkit now supports horizontal scrolling for pages with left overflow. But it has a bug in cross-platform that the backward mouse wheel does not work (you can not scroll backward below (0,0)). https://bugs.webkit.org/show_bug.cgi?id=50370 I tested the fix posted in the above bug, and I can manuall

I've seen the following assertion failure when I start Safari (in debug mode on my local build). I do not think it is related to my local change. And I've just deleted the "WebKitBuild" directory and rebuild. Anyone has any idea on what might be wrong here? Thanks, Xiaomei ASSERTION FAILED: !(si

[webkit-dev] [JavaScript] How to find a word user moused over

Hello, I am trying to write a JavaScript to find the word user moused over. FireFox supports event.rangeOffset, which is the *character* offset the cursor is at within the element. Given English word, using this offset, I can find the previous and next spaces and know the word under the cursor. B

[webkit-dev] JavaScript question: how to find out the position of a tooltip relative to the document body in a zoomed and scrolled page

I am trying to display a tooltip under the mouse when mouse stays at a position long enough. I am using "absolute" positioning, set the tooltip as the child of the document.body, and set the style.left and style.top as event.clientX + document.body.scrollLeft and event.clientY + documentbody.scroll

[webkit-dev] propose an API to return Range in etc. form control nodes (similar functionality as document.caretRangeFromPoint)

One use case is to show a tooltip of the word's definition in your accept-language when you mouse over the word in a page. It needs to 1. convert the mouse position to character offset within a node (by Document.caretRangeFromPoint()),

[webkit-dev] how to achieve similar behavior as event.rangeParent and event.rangeOffset in FireFox.

I am using caretRangeFromPoint to convert mouse position to the character position within an element. I am trying to use it to achieve the same behavior as event.rangeParent and event.rangeOffset in FireFox. So I think it should return different results if hit test on a text node or the text node's

Re: [webkit-dev] propose an API to return Range in etc. form control nodes (similar functionality as document.caretRangeFromPoint)

offset within the under mouse, 'offsetKind' is "control", what is the value of 'containingNode"? Is it itself or its shadowAncestorNode? Thanks, Xiaomei On Mon, Oct 12, 2009 at 1:50 PM, Maciej Stachowiak wrote: > > On Oct 12, 2009, at 1:08 AM, Anne van Kesteren

Re: [webkit-dev] propose an API to return Range in etc. form control nodes (similar functionality as document.caretRangeFromPoint)

t of view, I think we probably need to have a convenience method for converting a Range, and it probably should not give null for a control position. We would need both the node and the offset for further processing. Thanks, Xiaomei On Fri, Oct 16, 2009 at 10:39 AM, Maciej Stachowiak wrote: >
