Bug 48450

Created attachment 72219 [details] Adding the TouchAdjusts extension in the Platform Plugin.

Comment on attachment 72219 [details] Adding the TouchAdjusts extension in the Platform Plugin. I like to have this more like the Haptics. Thus call the Extension for Touch, and just make the plugin implement something like: class QWebTouchInteraction : public QObject { enum PaddingDirection { ... } virtual int hitTestPaddingForTouch(const PaddingDirection) const = 0; } I dislike the Adjust* and the setHitTestPadding is unneeded.

Btw, nice to have you back hacking on webkit!

Nice! When you change the platform plugin interface, please also change the version string.

I'll add a private QObject* m_extension variable and delete it in the plugin destructor. Other suggestion?

I'll add a private QObject* m_extension variable and delete it in the plugin destructor. Other suggestion? The user of the plugin should responsible for destroying the TouchInteraction object. createExtension caller should be the owner of the returned object.

Pedralho, please go for what luiz suggested. Other than that, looks good to me.

> > if (direction == PaddingDirection::Up) > return 15; > return 8; I think that something like this would make for a better, more clear example. Anyways, that is the whole point of an example - to be simple and easy to follow and understand.

I'm just thinking out loud... maybe others have comments. TouchInteraction is a better name but it is also the class name, then it conflicts. Suggestions?
