Bug 130182 – [EFL][WK2] Restore cursor when moving mouse into webview

• Component: WebKit EFL
• Status: RESOLVED FIXED

[Ryuan Choi]

Now, ewebkit changed mouse cursor when the type of cursor is changed.

But ewebkit does not know whether other widgets such as elm_entry change the cursor.
So we should restore the cursor when mouser enters on webview not to show wrong cursor.

Why don't you follow the alphabetic order?

Fixed order.

If possible, I prefer not to keep a member variable for boolean flag. Can't we pass this true/false to updateCursor() as an argument ?

Hmm, is m_cursorIdentifier still an address ?

Unfortunately, we should save the state of cursor for the MOUSE_IN callback.

Right, I removed the comment.

It looks m_useCustomCursor is only used by updateCursor(). Could you let me know how is this used by the MOUSE_IN callback ?

Yes and EwkViewEventHandler<EVAS_CALLBACK_MOUSE_IN>::handleEvent() and setCursor() call updateCursor().

Although we can pass the true/false to updateCursor(), we should keep the any member variable to know which type of cursor(group or image) we will restore in the MOUSE_IN callback.

I can't find "EwkViewEventHandler<EVAS_CALLBACK_MOUSE_IN>::handleEvent()" in EwkView.cpp. Is it supported by WebKit EFL trunk now ? Please let me know where it is implemented.

I missed to see "EwkViewEventHandler<EVAS_CALLBACK_MOUSE_IN>::handleEvent()" in this patch. Sorry for noise.

LGTM now.

Trivial recommendation : How about using isNull() explicitly as below ?

!cursor.image()->isNull()
