Detect selected row with force touch watchkit

Is it possible to detect selected row index with force touch? Did force touch in tableView current row is highlighted. But i can't take info about him when context menu appears. TableView method -didSelectRowAtIndex: not called with this event.
The only thing you can handle programmatically with the Force Touch is the Context Menu and this menu is associated with a specific controller, more information you will find following the link.
About the row highlighting: When you start tapping the system doesn't know what the real action is - the regular touch or the force one. So it is starting to highlight a specific area and only later find out what was the action.

for example displaying a div on that position and doing an action.
please give me help.

You could use hover jQuery function:
$(selector).hover( handlerIn(eventObject), handlerOut(eventObject) )
it takes 2 parameters:
1). Function which called on mouse goes in element
2). Function which called on mouse goes out element
In the first parameter you could show div, and hide it in the second one.

What is the proper name for a multibutton?

I'm trying to design a UI in Qt and I can't find anywhere in the designer a button which can be "droped down" like combobox. What I mean by that is that I would like to have this button with his "default" option choosen so if I like it I would have to just click on it but if I would like to choose different option I would be able to clik the little arrow on the right side of this button and then pick option suitable for me at that moment.
You're looking for a QToolButton that has a set of actions or a menu set on it. From the documentation, the QToolButton::ToolButtonPopupMode...
Describes how a menu should be popped up for tool buttons that has a menu set or contains a list of actions.
Of it's values, the two that I see most frequently are DelayedPopup:
After pressing and holding the tool button down for a certain amount of time (the timeout is style dependant, see QStyle::SH_ToolButton_PopupDelay), the menu is displayed. A typical application example is the "back" button in some web browsers's tool bars. If the user clicks it, the browser simply browses back to the previous page. If the user presses and holds the button down for a while, the tool button shows a menu containing the current history list
And MenuButtonPopup:
In this mode the tool button displays a special arrow to indicate that a menu is present. The menu is displayed when the arrow part of the button is pressed.
