Layout

Classes
struct	owl::TLayoutConstraint
	TLayoutConstraint is a structure that defines a relationship (a layout constraint) between an edge or size of one window and an edge or size of one of the window's siblings or its parent. More...
struct	owl::TEdgeConstraint
	TEdgeConstraint adds member functions that set edge (but not size) constraints. More...
struct	owl::TEdgeOrSizeConstraint
struct	owl::TEdgeOrWidthConstraint
struct	owl::TEdgeOrHeightConstraint
class	owl::TLayoutMetrics
	When specifying the layout metrics for a window, four layout constraints are needed. More...
class	owl::TLayoutWindow
	Derived from TWindow, TLayoutWindow provides functionality for defining the layout metrics for a window. More...

Macros
#define	lmParent   nullptr
	Use to represent the parent in layout metrics.

Enumerations
enum	owl::TEdge { owl::lmLeft , owl::lmTop , owl::lmRight , owl::lmBottom , owl::lmCenter }
	The TEdge enum describes the following constants that define the boundaries of a window: More...
enum	owl::TWidthHeight { owl::lmWidth = lmCenter + 1 , owl::lmHeight }
	Used by the TLayoutConstraint struct, TWidthHeight enumerates the values that control the width (lmWidth) and height (lmHeight) of the window. More...

	Used by the TLayoutConstraint struct, TRelationship specifies the relationship between the edges and sizes of one window and the edges and sizes of another window (which can be a parent or sibling). More...

Enumeration Type Documentation

TEdge

enum owl::TEdge

The TEdge enum describes the following constants that define the boundaries of a window:

Enumerator
lmLeft	The left edge of the window.
lmTop	The top edge of the window.
lmRight	The right edge of the window.
lmBottom	The bottom edge of the window.
lmCenter	The center of the window. The object that owns the constraint, such as TLayoutMetrics, determines whether the center of the window is the vertical center or the horizontal center.

Definition at line 35 of file layoutco.h.

TMeasurementUnits

enum owl::TMeasurementUnits

Used by the TLayoutConstraint struct, TMeasurementUnits enumerates the measurement units (lmPixels or lmLayoutUnits) that control the dimension of the window.

These can be either pixels or layout units that are obtained by dividing the font height into eight vertical and eight horizontal segments.

Note

To set the font, to which lmLayoutUnits are relative, you should call SetWindowFont. Otherwise, TLayoutWindow will use the obsolete SYSTEM_FONT to calculate the units.

Enumerator
lmPixels
lmLayoutUnits

TRelationship

enum owl::TRelationship

Used by the TLayoutConstraint struct, TRelationship specifies the relationship between the edges and sizes of one window and the edges and sizes of another window (which can be a parent or sibling).

These relationships can be specified as either the same value as the sibling or parent window (lmAsIs), an absolute value (lmAbsolute), a percent of one of the windows (lmPercentOf), a value that is either added above (lmAbove) or left (lmLeftOf) of one of the windows, or a value that is subtracted from below (lmBelow) or right (lmRightOf) of one of the windows.

Enumerator
lmAsIs
lmPercentOf
lmAbove
lmLeftOf
lmBelow
lmRightOf
lmSameAs
lmAbsolute

TWidthHeight

enum owl::TWidthHeight

Used by the TLayoutConstraint struct, TWidthHeight enumerates the values that control the width (lmWidth) and height (lmHeight) of the window.

Enumerator
lmWidth
lmHeight
