Methods

Method	Description
IXRButtonBase::AddClickEventHandler	Attaches a delegate to the Click event for this button. When the Click event is raised by this button, this delegate will be invoked.
IXRButtonBase::GetClickMode	Retrieves a value that specifies the action that raises the Click event for this button control.
IXRButtonBase::GetIsFocused	Retrieves a value that indicates whether the button control has the UI focus.
IXRButtonBase::GetIsMouseOver	Retrieves a value that indicates whether the mouse pointer is located over this button control.
IXRButtonBase::GetIsPressed	Retrieves a value that indicates whether this button control is currently in a pressed state.
IXRButtonBase::RemoveClickEventHandler	Removes a delegate from the Click event for this button control.
IXRButtonBase::SetClickMode	Sets a value that specifies the action that raises the Click event for this button control.

Thread Safety

Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

You can attach a delegate to the Click event in order to handle the event raised when the user clicks an object derived from IXRButtonBase. To do this, use the IXRButtonBase::AddClickEventHandler method.

Note

You should use the Click event to detect a button click instead of using MouseLeftButtonDown or MouseLeftButtonUp.

When you create a class instance, use an IXRButtonBasePtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
