   3 A flex grid sizer is a sizer which lays out its children in a two-dimensional
   4 table with all table fields in one row having the same
   5 height and all fields in one column having the same width, but all
   6 rows or all columns are not necessarily the same height or width as in
   7 the \helpref{wxGridSizer}{wxgridsizer}.
   8
   9 Since wxWidgets 2.5.0, wxFlexGridSizer can also size items equally in one
  10 direction but unequally ("flexibly") in the other. If the sizer is only
  11 flexible in one direction (this can be changed using
  12 \helpref{SetFlexibleDrection}{wxflexgridsizersetflexibledirection}),
  13 it needs to be decided how the sizer should grow in the other ("non flexible")
  14 direction in order to fill the available space. The
  15 \helpref{SetNonFlexibleGrowMode}{wxflexgridsizersetnonflexiblegrowmode} method
  16 serves this purpose.

  36
  37 \func{}{wxFlexGridSizer}{\param{int }{cols}, \param{int }{vgap = 0}, \param{int }{hgap = 0}}
  38
  39 Constructor for a wxGridSizer. {\it rows} and {\it cols} determine the number of
  40 columns and rows in the sizer - if either of the parameters is zero, it will be
  41 calculated to form the total number of children in the sizer, thus making the
  42 sizer grow dynamically. {\it vgap} and {\it hgap} define extra space between
  43 all children.

  46 \membersection{wxFlexGridSizer::AddGrowableCol}\label{wxflexgridsizeraddgrowablecol}
  47
  48 \func{void}{AddGrowableCol}{\param{size\_t }{idx}, \param{int }{proportion = $0$}}
  49
  50 Specifies that column {\it idx} (starting from zero) should be grown if
  51 there is extra space available to the sizer.
  52
  53 The {\it proportion} parameter has the same meaning as the stretch factor for
  54 the \helpref{sizers}{sizeroverview} except that if all proportions are $0$,
  55 then all columns are resized equally (instead of not being resized at all).
  56
  57 \membersection{wxFlexGridSizer::AddGrowableRow}\label{wxflexgridsizeraddgrowablerow}
  58
  59 \func{void}{AddGrowableRow}{\param{size\_t }{idx}, \param{int }{proportion = $0$}}
  60
  61 Specifies that row idx (starting from zero) should be grown if there
  62 is extra space available to the sizer.
  63
  64 See \helpref{AddGrowableCol}{wxflexgridsizeraddgrowablecol} for the description
  65 of {\it proportion} parameter.

  68
  69 \constfunc{int}{GetFlexibleDirections}{\void}
  70
  71 Returns a wxOrientation value that specifies whether the sizer flexibly
  72 resizes its columns, rows, or both (default).
  73
  74 \wxheading{Return value}
  75
  76 One of the following values:
  77
  78 \begin{twocollist}
  79 \twocolitem{wxVERTICAL}{Rows are flexibly sized.}
  80 \twocolitem{wxHORIZONTAL}{Columns are flexibly sized.}
  81 \twocolitem{wxBOTH}{Both rows and columns are flexibly sized (this is the default value).}

  90
  91 \constfunc{int}{GetNonFlexibleGrowMode}{\void}
  92
  93 Returns the value that specifies how the sizer grows in the "non flexible"
  94 direction if there is one.
  95
  96 \wxheading{Return value}
  97
  98 One of the following values:
  99
 100 \begin{twocollist}
 101 \twocolitem{wxFLEX\_GROWMODE\_NONE}{Sizer doesn't grow in the non flexible direction.}
 102 \twocolitem{wxFLEX\_GROWMODE\_SPECIFIED}{Sizer honors growable columns/rows set with
 103 \helpref{AddGrowableCol}{wxflexgridsizeraddgrowablecol} and
 104 \helpref{AddGrowableRow}{wxflexgridsizeraddgrowablerow}.
 105 In this case equal sizing applies to minimum sizes of columns or
 106 rows (this is the default value).}
 107 \twocolitem{wxFLEX\_GROWMODE\_ALL}{Sizer equally stretches all columns or rows
 108 in the non flexible direction, whether they are growable or not in the flexbile
 109 direction.}

 119
 120 \func{void}{RemoveGrowableCol}{\param{size\_t }{idx}}
 121
 122 Specifies that column idx is no longer growable.

 126
 127 \func{void}{RemoveGrowableRow}{\param{size\_t }{idx}}

 132 \membersection{wxFlexGridSizer::SetFlexibleDirection}\label{wxflexgridsizersetflexibledirection}
 133
 134 \func{void}{SetFlexibleDirections}{\param{int }{direction}}
 135
 136 Specifies whether the sizer should flexibly resize its columns, rows, or
 137 both. Argument {\tt direction} can be {\tt wxVERTICAL}, {\tt wxHORIZONTAL}
 138 or {\tt wxBOTH} (which is the default value). Any other value is ignored. See
 139 \helpref{GetFlexibleDirection()}{wxflexgridsizergetflexibledrection} for the
 140 explanation of these values.
 141
 142 Note that this method does not trigger relayout.

 145 \membersection{wxFlexGridSizer::SetNonFlexibleGrowMode}\label{wxflexgridsizersetnonflexiblegrowmode}
 146
 147 \func{void}{SetNonFlexibleGrowMode}{\param{int }{mode}}
 148
 149 Specifies how the sizer should grow in the non flexible direction if
 150 there is one (so
 151 \helpref{SetFlexibleDirections()}{wxflexgridsizersetflexibledirection} must have
 152 been called previously). Argument {\it mode} can be one of those documented in
 153 \helpref{GetNonFlexibleGrowMode}{wxflexgridsizergetnonflexiblegrowmode}, please
 154 see there for their explanation.
 155
 156 Note that this method does not trigger relayout.
