Member Function Documentation

getGuiScale()

fge::Vector2f const & fge::GuiElement::getGuiScale ( ) const

inlinenodiscardinherited

Get the scale of the element.

Returns

The scale of the element

getPriority()

fge::GuiElement::Priority fge::GuiElement::getPriority ( ) const

inlinenodiscardinherited

Get the priority of the element.

Returns

The priority of the element

isRecursive()

bool fge::GuiElementRecursive::isRecursive ( ) const

inlinefinalvirtual

Check if this GuiElement is recursive.

A gui element is recursive if it handle others GuiElements.

Returns

true if it is recursive, false otherwise

Reimplemented from fge::GuiElement.

onGuiVerify()

virtual void fge::GuiElement::onGuiVerify ( fge::Event const & evt, SDL_EventType evtType, fge::GuiElementContext & context )

pure virtualinherited

Function called to verify if the element is hovered by the mouse.

This function should call verifyPriority to verify the priority of the element. If the priority is higher than the given element, the function should replace the provided pointer reference element with the element itself.

Parameters

evt	An fge::Event
evtType	The type of the SDL event called
context	The GuiElement context

Implemented in fge::GuiElementArray, fge::GuiElementDefault, and fge::GuiElementRectangle.

setGuiScale()

void fge::GuiElement::setGuiScale ( fge::Vector2f const & scale )

inlineinherited

Set the scale of the element.

Parameters

scale

The scale of the element

setPriority()

void fge::GuiElement::setPriority ( fge::GuiElement::Priority priority ) const

inlineinherited

Set the priority of the element.

The priority value can be used with the scene DepthPlan.

Parameters

priority

The priority of the element

verifyPriority()

bool fge::GuiElement::verifyPriority ( fge::GuiElement * element ) const

inlinenodiscardinherited

Verify if the priority of the element is higher than the given element.

If the provided element is null, the function will assume that the element is the highest priority.

Parameters

element

The element to compare with

Returns

true if the priority of the element is higher than the given element, false otherwise
