• Status: RESOLVED FIXED

[Mario Sanchez Prada]

We need to get rid of Pango/Gail dependency, and this is one of the functionalities we would need to fix.

Patch proposal for this use case. Additional tests are not needed since we are replacing and old implementation, and so this functionality is tested by the testWebkitAtkGetTextAtOffset*() family of functions inside testatk.c

This is the right one. Seriously.

This new patch avoids defining that function for the EFL platform

Not sure I understand why this is still behind an #ifdef is the code can be shared now. Here's the compilation problem on EFL, I think:

I just kept them there not to break EFL behaviour (even if so far it's just "being not implemented"), but I'm currently talking to EFL guys to see what it's best. Probably sharing it, as you mentioned.

In any case, another open question is whether we should move WebCore/accessibility to WebCore/platform/accessibility since, after all, a11y layer is pretty much a platform dependent thing.

Here's the compilation problem on EFL, I think:

Argh! I should rebase my local branch it seems, to pick Edu's patch.

/mnt/eflews/git/webkit/Source/WebCore/accessibility/atk/WebKitAccessibleInterfaceText.cpp:578:15: error: 'gchar* webkitAccessibleTextGetChar(AtkText*, gint, GetTextRelativePosition, gint*, gint*)' defined but not used [-Werror=unused-function]

That's what this last patch should have fixed.

I talked to EFL guys and they do not see any problem in sharing this implementation, now it's free from Pango/Gail stuff, so here it's the patch.

About the other bits (moving stuff into WebCore/platform), I'll send an email about that to discuss it properly.

Please use visiblePosition here for the variable name.
