49514 2010-11-14 14:03:38 -0800 [Gtk] atk_text_get_selection returns the wrong offsets after a link 2010-11-18 06:28:10 -0800 1 1 1 Unclassified WebKit Accessibility 528+ (Nightly build) PC Linux RESOLVED FIXED Gtk P2 Normal --- 25531 0 jdiggs webkit-unassigned abarth apinheiro eric mario webkit.review.bot xan.lopez oldest_to_newest 309105 0 73857 jdiggs 2010-11-14 14:03:38 -0800 Created attachment 73857 test case Steps to reproduce: 1. Load the test case in Epiphany and launch Accerciser. 2. For each paragraph: a. Select the word 'test' b. Select the paragraph in Accerciser's object tree. c. With the pargraph selected, get the first selection by typing 'acc.queryText().getSelection(0)' in the iPython console. Expected results: The startOffset and endOffset for the selection would be the same for each paragraph, because the word 'test' appears at the same character offsest in each paragraph. Actual results: The startOffset and endOffset for the selection in each paragraph is different, with offset 0 appearing to be the first character after the link: In [1]: acc.queryText().getSelection(0) Out[1]: (10, 14) In [2]: acc.queryText().getSelection(0) Out[2]: (6, 10) In [3]: acc.queryText().getSelection(0) Out[3]: (3, 7) In [4]: acc.queryText().getSelection(0) Out[4]: (1, 5) Impact: Orca incorrectly states that text is not selected when it is selected. In addition, it displays the wrong text as being selected on the braille display. 309106 1 jdiggs 2010-11-14 14:04:25 -0800 Note: I'm blocking bug 25531 as correctly indicating text selection is part of the basic functionality users will expect to have in Yelp 3.0. 309269 2 73892 mario 2010-11-15 07:09:12 -0800 Created attachment 73892 Patch proposal It looks we were not calculating the startOffset value properly, by taking into account the possibility of some embedded objects being present in the paragraph, previous to the currently selected text (my fault). The attached patch would fix this by checking the startOffset value more carefully. As the patch also fixes a bunch of not-properl-ended-comments (without '.'), I'm pasting here the so simple diff for simplicity of review: In getSelectionOffsetsForObject(), at AccessibilityObjectWrapperAtk.cpp: [...] Node* lastLeafNode = node->lastDescendant(); if (selRange->isPointInRange(lastLeafNode, lastOffsetInNode(lastLeafNode), ec)) nodeRangeEnd = lastPositionInNode(lastLeafNode); else nodeRangeEnd = selRange->endPosition(); - // Set values for start and end offsets + // Calculate position of the selected range inside the object. + Position parentFirstPosition = firstPositionInNode(node); + RefPtr<Range> rangeInParent = Range::create(node->document(), parentFirstPosition, nodeRangeStart); + + // Set values for start and end offsets. + startOffset = TextIterator::rangeLength(rangeInParent.get()); RefPtr<Range> nodeRange = Range::create(node->document(), nodeRangeStart, nodeRangeEnd); - startOffset = nodeRangeStart.offsetInContainerNode(); endOffset = startOffset + TextIterator::rangeLength(nodeRange.get()); [...] 310367 3 74131 mario 2010-11-17 10:31:40 -0800 Created attachment 74131 Patch proposal + Unit test Attaching a new patch adding the needed bits in an already existing test case to check this specific subcase (double checked that this new check fails without this patch, in case you wonder).
