Bug 54633 – [Gtk] webkit_web_view_popup_menu_handler should call SelectionController::localCaretRect

• Component: HTML Editing
• Status: RESOLVED FIXED

[Ryosuke Niwa]

webkit_web_view_popup_menu_handler currently obtains selection start's coordinates by manually accessing selection start's renderer.  But it should instead call SelectionController::localCaretRect.

[Xan Lopez]

The a11y code uses boundsForVisiblePositionRange to get the text extents, Ryosuke says that's likely wrong too. CCing Mario.

Ryosuke, Xan asked me to ping you for the review for this issue.

You must be using an old checkout.  Position::node() no longer exists.  What you want to do here is probably selection->selection()->isNonOrphanedCaretOrRange() since when start() or end() is orphaned, meaning that they're detached from the document, it doesn't make sense to query the firstRectForRange on that selection.

firstRange() will return 0 if selection->isNone().  You probably need to check this condition above as well (fortunately, if isNonOrphanedCaretOrRange returns true, then isNone is false so the suggested change above will fix this as well).

I can't review these changes.  Xan or someone else should do.

This patch was written before the change to ::node, I think. Made the fix you suggested here.

Sorry for the delayed response.  I didn't realize you had uploaded a new patch.  The editing part of the change looks good to me.

Don't you want to avoid doing this check when caret navigation is on?

[Ryosuke Niwa]

Xan, can you review GTK part of it so that Martin can land this patch?

I will change this to "Never let the context menu touch the very edge of the view."
