49 use create a wx.LayoutContstraints instance and use the individual contstraints
50 that it contains.

52 Constraints are initially set to have the relationship wx.Unconstrained, which
53 means that their values should be calculated by looking at known constraints.

55 The Edge specifies the type of edge or dimension of a window.

57 Edges
58
59 wx.Left The left edge.
60 wx.Top The top edge.
61 wx.Right The right edge.
62 wx.Bottom The bottom edge.
63 wx.CentreX The x-coordinate of the centre of the window.
64 wx.CentreY The y-coordinate of the centre of the window.
65
66
67 The Relationship specifies the relationship that this edge or dimension has
68 with another specified edge or dimension. Normally, the user doesn't use these
69 directly because functions such as Below and RightOf are a convenience for
70 using the more general Set function.
71
72 Relationships
73
74 wx.Unconstrained The edge or dimension is unconstrained
75 (the default for edges.)
76 wx.AsIs The edge or dimension is to be taken from the current
77 window position or size (the default for dimensions.)
78 wx.Above The edge should be above another edge.
79 wx.Below The edge should be below another edge.
80 wx.LeftOf The edge should be to the left of another edge.
81 wx.RightOf The edge should be to the right of another edge.
82 wx.SameAs The edge or dimension should be the same as another edge
83 or dimension.
84 wx.PercentOf The edge or dimension should be a percentage of another
85 edge or dimension.
86 wx.Absolute The edge or dimension should be a given absolute value.

215 Objects of this class can be associated with a window to define its layout
216 constraints, with respect to siblings or its parent.
217
218 The class consists of the following eight constraints of class
219 wx.IndividualLayoutConstraint, some or all of which should be accessed
220 directly to set the appropriate constraints.
221
222 * left: represents the left hand edge of the window
223 * right: represents the right hand edge of the window
224 * top: represents the top edge of the window
225 * bottom: represents the bottom edge of the window
226 * width: represents the width of the window
227 * height: represents the height of the window
228 * centreX: represents the horizontal centre point of the window
229 * centreY: represents the vertical centre point of the window
230
231 Most constraints are initially set to have the relationship wxUnconstrained,
232 which means that their values should be calculated by looking at known
233 constraints. The exceptions are width and height, which are set to wxAsIs to
234 ensure that if the user does not specify a constraint, the existing width and
235 height will be used, to be compatible with panel items which often have take a
236 default size. If the constraint is wxAsIs, the dimension will not be changed.
