Parameters:

  | id,: | Id to search for.
  | searchchildren,: | Set this to true, if also children of this element may contain the element with the searched id and they should be searched too.

Note that the root element is the size of the screen, so doing so (with an on-screen point) will always return the root element if no other element is above it at that point.

Parameters:

Returns:
  The topmost GUI element at that point, or 0 if there are no candidate elements at this point.

References ToolTipText.

EGUI_ELEMENT_TYPE irr::gui::IGUIElement::getType | ( |  | ) | const`[inline]`

Returns the type of the gui element.

This is needed for the .NET wrapper but will be used later for serializing and deserializing. If you wrote your own GUIElements, you need to set the type for your element as first parameter in the constructor of IGUIElement. For own (=unknown) elements, simply use EGUIET_ELEMENT as type

Definition at line 681 of file IGUIElement.h.

References Type.

virtual const c8* irr::gui::IGUIElement::getTypeName | ( |  | ) | const`[inline, virtual]`

Returns the type name of the gui element.

This is needed serializing elements. For serializing your own elements, override this function and return your own type name which is created by your IGUIElementFactory

Definition at line 704 of file IGUIElement.h.

References irr::gui::GUIElementTypeNames, and Type.

virtual bool irr::gui::IGUIElement::hasType | ( | EGUI_ELEMENT_TYPE | type | ) | const`[inline, virtual]`

Returns true if the gui element supports the given type.

This is mostly used to check if you can cast a gui element to the class that goes with the type. Most gui elements will only support their own type, but if you derive your own classes from interfaces you can overload this function and add a check for the type of the base-class additionally. This allows for checks comparable to the dynamic_cast of c++ with enabled rtti. Note that you can't do that by calling BaseClass::hasType(type), but you have to do an explicit comparison check, because otherwise the base class usually just checks for the membervariable Type which contains the type of your derived class.

virtual bool irr::gui::IGUIElement::isEnabled | ( |  | ) | const`[inline, virtual]`

bool irr::gui::IGUIElement::isMyChild | ( | IGUIElement * | child | ) | const`[inline]`

Parameters:

  | child,: | The child element to check

References _IRR_IMPLEMENT_MANAGED_MARSHALLING_BUGFIX, and Parent.

bool irr::gui::IGUIElement::isNotClipped | ( |  | ) | const`[inline]`

Returns:
  true if the element is not clipped by its parent's clipping rectangle.

Definition at line 163 of file IGUIElement.h.

References NoClip.

virtual bool irr::gui::IGUIElement::isPointInside | ( | const core::position2d< s32 > & | point | ) | const`[inline, virtual]`
