13
14 A flex grid sizer is a sizer which lays out its children in a two-dimensional
15 table with all table fields in one row having the same
16 height and all fields in one column having the same width, but all
17 rows or all columns are not necessarily the same height or width as in
18 the \helpref{wxGridSizer}{wxgridsizer}.
19
20 Since wxWidgets 2.5.0, wxFlexGridSizer can also size items equally in one
21 direction but unequally ("flexibly") in the other. If the sizer is only
22 flexible in one direction (this can be changed using
23 \helpref{SetFlexibleDirection}{wxflexgridsizersetflexibledirection}),
24 it needs to be decided how the sizer should grow in the other ("non-flexible")
25 direction in order to fill the available space. The
26 \helpref{SetNonFlexibleGrowMode}{wxflexgridsizersetnonflexiblegrowmode} method
27 serves this purpose.

48
49 \func{}{wxFlexGridSizer}{\param{int }{cols}, \param{int }{vgap = 0}, \param{int }{hgap = 0}}
50
51 Constructor for a wxGridSizer. {\it rows} and {\it cols} determine the number of
52 columns and rows in the sizer - if either of the parameters is zero, it will be
53 calculated to form the total number of children in the sizer, thus making the
54 sizer grow dynamically. {\it vgap} and {\it hgap} define extra space between
55 all children.
56
57
58 \membersection{wxFlexGridSizer::AddGrowableCol}\label{wxflexgridsizeraddgrowablecol}
59
60 \func{void}{AddGrowableCol}{\param{size\_t }{idx}, \param{int }{proportion = $0$}}
61
62 Specifies that column {\it idx} (starting from zero) should be grown if
63 there is extra space available to the sizer.
64
65 The {\it proportion} parameter has the same meaning as the stretch factor for
66 the \helpref{sizers}{sizeroverview} except that if all proportions are $0$,
67 then all columns are resized equally (instead of not being resized at all).
68
69 \membersection{wxFlexGridSizer::AddGrowableRow}\label{wxflexgridsizeraddgrowablerow}
70
71 \func{void}{AddGrowableRow}{\param{size\_t }{idx}, \param{int }{proportion = $0$}}
72
73 Specifies that row idx (starting from zero) should be grown if there
74 is extra space available to the sizer.
75
76 See \helpref{AddGrowableCol}{wxflexgridsizeraddgrowablecol} for the description
77 of {\it proportion} parameter.
78
79 \membersection{wxFlexGridSizer::GetFlexibleDirection}\label{wxflexgridsizergetflexibledrection}
80
81 \constfunc{int}{GetFlexibleDirection}{\void}
82
83 Returns a wxOrientation value that specifies whether the sizer flexibly
84 resizes its columns, rows, or both (default).
85
86 \wxheading{Return value}
87
88 One of the following values:
89
90 \begin{twocollist}
91 \twocolitem{wxVERTICAL}{Rows are flexibly sized.}
92 \twocolitem{wxHORIZONTAL}{Columns are flexibly sized.}
93 \twocolitem{wxBOTH}{Both rows and columns are flexibly sized (this is the default value).}

101 \membersection{wxFlexGridSizer::GetNonFlexibleGrowMode}\label{wxflexgridsizergetnonflexiblegrowmode}
102
103 \constfunc{int}{GetNonFlexibleGrowMode}{\void}
104
105 Returns the value that specifies how the sizer grows in the "non-flexible"
106 direction if there is one.
107
108 \wxheading{Return value}
109
110 One of the following values:
111
112 \begin{twocollist}
113 \twocolitem{wxFLEX\_GROWMODE\_NONE}{Sizer doesn't grow in the non-flexible direction.}
114 \twocolitem{wxFLEX\_GROWMODE\_SPECIFIED}{Sizer honors growable columns/rows set with
115 \helpref{AddGrowableCol}{wxflexgridsizeraddgrowablecol} and
116 \helpref{AddGrowableRow}{wxflexgridsizeraddgrowablerow}.
117 In this case equal sizing applies to minimum sizes of columns or
118 rows (this is the default value).}
119 \twocolitem{wxFLEX\_GROWMODE\_ALL}{Sizer equally stretches all columns or rows
120 in the non-flexible direction, whether they are growable or not in the flexible
121 direction.}

130 \membersection{wxFlexGridSizer::RemoveGrowableCol}\label{wxflexgridsizerremovegrowablecol}
131
132 \func{void}{RemoveGrowableCol}{\param{size\_t }{idx}}
133
134 Specifies that column idx is no longer growable.
135
136
137 \membersection{wxFlexGridSizer::RemoveGrowableRow}\label{wxflexgridsizerremovegrowablerow}
138
139 \func{void}{RemoveGrowableRow}{\param{size\_t }{idx}}
140
141 Specifies that row idx is no longer growable.
142
143
144 \membersection{wxFlexGridSizer::SetFlexibleDirection}\label{wxflexgridsizersetflexibledirection}
145
146 \func{void}{SetFlexibleDirection}{\param{int }{direction}}
147
148 Specifies whether the sizer should flexibly resize its columns, rows, or
149 both. Argument {\tt direction} can be {\tt wxVERTICAL}, {\tt wxHORIZONTAL}
150 or {\tt wxBOTH} (which is the default value). Any other value is ignored. See
151 \helpref{GetFlexibleDirection()}{wxflexgridsizergetflexibledrection} for the
152 explanation of these values.
153
154 Note that this method does not trigger relayout.

157 \membersection{wxFlexGridSizer::SetNonFlexibleGrowMode}\label{wxflexgridsizersetnonflexiblegrowmode}
158
159 \func{void}{SetNonFlexibleGrowMode}{\param{wxFlexSizerGrowMode }{mode}}
160
161 Specifies how the sizer should grow in the non-flexible direction if
162 there is one (so
163 \helpref{SetFlexibleDirection()}{wxflexgridsizersetflexibledirection} must have
164 been called previously). Argument {\it mode} can be one of those documented in
165 \helpref{GetNonFlexibleGrowMode}{wxflexgridsizergetnonflexiblegrowmode}, please
166 see there for their explanation.
167
168 Note that this method does not trigger relayout.
