Member Function Documentation

clone()

virtual InteractionEvent * inviwo::InteractionEvent::clone ( ) const

overridepure virtual

Implements inviwo::Event.

setToolTip()

void inviwo::InteractionEvent::setToolTip

(

std::string_view

tooltip

)

const

Display a tool tip using the optionally set tool tip callback. If no tool tip callback is set, the function does nothing. The supported formation depends on the used back end, but simple html is usually supported. Calling the function with an empty sting will hide any existing tool tip.

setToolTipCallback()

void inviwo::InteractionEvent::setToolTipCallback

(

ToolTipCallback

callback

)

Set a tool tip call back function. The function should display a tool tip with the given string at the position of the event. This function is usually called by the originating event canvas, and not any regular user code.

showContextMenu()

void inviwo::InteractionEvent::showContextMenu	(	std::span< ContextMenuEntry >	entries,
		ContextMenuCategories	categories = ContextMenuCategory::Callback )

Show a context menu at the current mouse position. The custom menu entries are added before any other default actions based on categories. When any of the custom menu actions in the entries is triggered, a ContexMenuEvent with the corresponding entry ID will be propagated through the processor network.

Parameters

entries	list of custom menu items
categories	determines which menu actions should be included in the context menu
