QWebPage::inputMethodQuery(Qt::ImAnchorPosition) returns the start index (renderTextControl->selectionStart()) of a selection inside an input field instead of the anchor position. To be specific: In Webkit, the START and END indices always correspond to the left and right edges of a selection irrespective of the current cursor direction. The bug is that the current implementation of QWebPage::inputMethodQuery() assumes incorrectly that the anchor position is the START index and that the current cursor position always corresponds to the END index. 222675 1 rajiv.ramanasankaran 2010-05-07 15:58:19 -0700 I am working on a patch for submission. 224596 2 jesus 2010-05-12 07:28:06 -0700 (In reply to comment #1) > I am working on a patch for submission.

Thanks! Just to clarify: I am working on a patch (including the fix and auto-tests) for submission. 226592 4 56206 rajiv.ramanasankaran 2010-05-16 19:47:14 -0700 Created attachment 56206 Prosposed patch to fix the return values for Qt::ImCursorPosition and Qt::ImAnchorPosition in QWebPage::inputMethodQuery() when the Editor doesn't have a composition.

Funny, tst_qwebpage has: //Set selection with negative length inputAttributes << QInputMethodEvent::Attribute(QInputMethodEvent::Selection, 6, -5, QVariant()); QInputMethodEvent eventSelection3("",inputAttributes); page->event(&eventSelection3); //ImAnchorPosition variant = page->inputMethodQuery(Qt::ImAnchorPosition); anchorPosition = variant.toInt(); QCOMPARE(anchorPosition, 1); //ImCursorPosition variant = page->inputMethodQuery(Qt::ImCursorPosition); cursorPosition = variant.toInt(); QCOMPARE(cursorPosition, 6); which would suggest the opposite to me, but I don't know too much about input methods. 226894 8 rajiv.ramanasankaran 2010-05-17 14:17:23 -0700 (In reply to comment #7) > (In reply to comment #6) > > (In reply to comment #5) > > > So is it not solvable when in Composition mode?

This test case causes the Editor to go into composistion mode and therefore QWebPage::inputMethodQuery() returns the correct values. I don't know whether it is supposed to go into composition mode in this case or not (And that is the concern I raised in an email to you last week since this test case was part of your commit #58218). The test case I am fixing is when the editor is not in composition mode and is different than this. 227487 9 56206 hausmann 2010-05-18 13:58:17 -0700 Comment on attachment 56206 Prosposed patch to fix the return values for Qt::ImCursorPosition and Qt::ImAnchorPosition in QWebPage::inputMethodQuery() when the Editor doesn't have a composition. r=me 228358 10 56206 commit-queue 2010-05-20 06:57:12 -0700 Comment on attachment 56206 Prosposed patch to fix the return values for Qt::ImCursorPosition and Qt::ImAnchorPosition in QWebPage::inputMethodQuery() when the Editor doesn't have a composition.
