AutomationPeer.GetClickablePointCore method

Provides the peer's behavior when a Microsoft UI Automation client calls GetClickablePoint or an equivalent UI Automation client API.

Syntax


Protected Overridable Function GetClickablePointCore() As Point

Parameters

This method has no parameters.

Return value

Type: Point

A point within the clickable area of the element.

Remarks

The base implementation returns a default Point (coordinates 0,0). Peers that represent items defer to the container. ScrollBarAutomationPeer and SliderAutomationPeer both have behavior that can't adequately express one point for the purposes of GetClickablePoint scenarios, so these return a Point where the coordinate values are Double.NaN.

Note  Visual C++ component extensions (C++/CX) doesn't have a constant for NaN, it uses a value, which appears as "-1.#IND" followed by zeros. Automation clients using languages other than C# or C++/CX may see NaN represented in a different form.
