Detailed Description

Base Class for all rendering tree objects.

Definition at line 146 of file render_object.h.

Member Enumeration Documentation

◆ CaretFlags

enum khtml::RenderObject::CaretFlags

Flags which influence the appearance and position.

Parameters
CFOverrideinput overrides existing character, caret should be cover the whole character
CFOutsidecoordinates are to be interpreted outside of the render object
CFOutsideEndcoordinates are to be interpreted at the outside end of the render object (only valid if CFOutside is also set)

Definition at line 1301 of file render_object.h.

Member Function Documentation

◆ caretMaxOffset()

long RenderObject::caretMaxOffset ( ) const
virtual

returns the highest possible value the caret offset may have to still point to a valid position.

Returns 0 by default, as generic elements are considered to have no width.

Definition at line 3018 of file render_object.cpp.

◆ caretMinOffset()

long RenderObject::caretMinOffset ( ) const
virtual

returns the lowest possible value the caret offset may have to still point to a valid position.

Returns 0 by default.

Definition at line 3013 of file render_object.cpp.

◆ caretPos()

void RenderObject::caretPos ( int  offset,
int  flags,
int &  _x,
int &  _y,
int &  width,
int &  height 
) const
virtual

Returns the content coordinates of the caret within this render object.

Parameters
offsetzero-based offset determining position within the render object.
flagscombination of enum CaretFlags
_xreturns the left coordinate
_yreturns the top coordinate
widthreturns the caret's width
heightreturns the caret's height

Definition at line 2400 of file render_object.cpp.

◆ container()

RenderObject * RenderObject::container ( ) const

returns the object containing this one.

can be different from parent for positioned elements

Definition at line 2463 of file render_object.cpp.

◆ effectiveHeight()

int khtml::RenderObject::effectiveHeight ( ) const
inline

Returns the height that is effectively considered when contemplating the object as a whole – usually the overflow height, or the height if clipped.

Definition at line 1083 of file render_object.h.

◆ effectiveWidth()

int khtml::RenderObject::effectiveWidth ( ) const
inline

Returns the width that is effectively considered when contemplating the object as a whole – usually the overflow width, or the width if clipped.

Definition at line 1092 of file render_object.h.

◆ effectiveXPos()

int khtml::RenderObject::effectiveXPos ( ) const
inline

the position of the object from where it begins drawing, including its negative overflow

Definition at line 1016 of file render_object.h.

◆ effectiveYPos()

int khtml::RenderObject::effectiveYPos ( ) const
inline

the position of the object from where it begins drawing, including its negative overflow

Definition at line 1024 of file render_object.h.

◆ inlineXPos()

virtual int khtml::RenderObject::inlineXPos ( ) const
inlinevirtual

Leftmost coordinate of this inline element relative to containing block.

Always zero for non-inline elements.

Definition at line 1032 of file render_object.h.

◆ inlineYPos()

virtual int khtml::RenderObject::inlineYPos ( ) const
inlinevirtual

Topmost coordinate of this inline element relative to containing block.

Always zero for non-inline elements.
