   3
   4 A \helpref{wxSizer}{wxsizer} that can lay out items in a virtual grid
   5 like a \helpref{wxFlexGridSizer}{wxflexgridsizer} but in this case
   6 explicit positioning of the items is allowed using
   7 \helpref{wxGBPosition}{wxgbposition}, and items can optionally span
   8 more than one row and/or column using \helpref{wxGBSpan}{wxgbspan}.

  24
  25 \func{}{wxGridBagSizer}{\param{int }{vgap = 0}, \param{int }{hgap = 0}}
  26
  27 Constructor, with optional parameters to specify the gap between the
  28 rows and columns.
  29
  30 \membersection{wxGridBagSizer::Add}\label{wxgridbagsizeradd}
  31
  32 \func{bool}{Add}{\param{wxWindow* }{window}, \param{const wxGBPosition\& }{pos}, \param{const wxGBSpan\& }{span = wxDefaultSpan}, \param{int }{flag = 0}, \param{int }{border = 0}, \param{wxObject* }{userData = NULL}}
  33
  34 \func{bool}{Add}{\param{wxSizer* }{sizer}, \param{const wxGBPosition\& }{pos}, \param{const wxGBSpan\& }{span = wxDefaultSpan}, \param{int }{flag = 0}, \param{int }{border = 0}, \param{wxObject* }{userData = NULL}}
  35
  36 \func{bool}{Add}{\param{int }{width}, \param{int }{height}, \param{const wxGBPosition\& }{pos}, \param{const wxGBSpan\& }{span = wxDefaultSpan}, \param{int }{flag = 0}, \param{int }{border = 0}, \param{wxObject* }{userData = NULL}}
  37
  38 \func{bool}{Add}{\param{wxGBSizerItem* }{item}}
  39
  40 The Add methods return true if the item was successfully placed at the
  41 given position, false if something was already there.
  42
  43 \membersection{wxGridBagSizer::CalcMin}\label{wxgridbagsizercalcmin}
  44
  45 \func{wxSize}{CalcMin}{\void}
  46
  47 Called when the managed size of the sizer is needed or when layout
  48 needs done.
  49
  50 \membersection{wxGridBagSizer::CheckForIntersection}\label{wxgridbagsizercheckforintersection}
  51
  52 \func{bool}{CheckForIntersection}{\param{wxGBSizerItem* }{item}, \param{wxGBSizerItem* }{excludeItem = NULL}}
  53
  54 \func{bool}{CheckForIntersection}{\param{const wxGBPosition\& }{pos}, \param{const wxGBSpan\& }{span}, \param{wxGBSizerItem* }{excludeItem = NULL}}
  55
  56 Look at all items and see if any intersect (or would overlap) the given
  57 item. Returns true if so, false if there would be no overlap. If an
  58 excludeItem is given then it will not be checked for intersection, for
  59 example it may be the item we are checking the position of.

  61 \membersection{wxGridBagSizer::FindItem}\label{wxgridbagsizerfinditem}
  62
  63 \func{wxGBSizerItem*}{FindItem}{\param{wxWindow* }{window}}
  64
  65 \func{wxGBSizerItem*}{FindItem}{\param{wxSizer* }{sizer}}
  66
  67 Find the sizer item for the given window or subsizer, returns NULL if
  68 not found. (non-recursive)
  69
  70 \membersection{wxGridBagSizer::FindItemAtPoint}\label{wxgridbagsizerfinditematpoint}
  71
  72 \func{wxGBSizerItem*}{FindItemAtPoint}{\param{const wxPoint\& }{pt}}
  73
  74 Return the sizer item located at the point given in pt, or NULL if
  75 there is no item at that point. The (x,y) coordinates in pt correspond
  76 to the client coordinates of the window using the sizer for
  77 layout. (non-recursive)
  78
  79 \membersection{wxGridBagSizer::FindItemAtPosition}\label{wxgridbagsizerfinditematposition}
  80
  81 \func{wxGBSizerItem*}{FindItemAtPosition}{\param{const wxGBPosition\& }{pos}}
  82
  83 Return the sizer item for the given grid cell, or NULL if there is no
  84 item at that position. (non-recursive)
  85
  86 \membersection{wxGridBagSizer::FindItemWithData}\label{wxgridbagsizerfinditemwithdata}
  87
  88 \func{wxGBSizerItem*}{FindItemWithData}{\param{const wxObject* }{userData}}
  89
  90 Return the sizer item that has a matching user data (it only compares
  91 pointer values) or NULL if not found. (non-recursive)
  92
  93 \membersection{wxGridBagSizer::GetCellSize}\label{wxgridbagsizergetcellsize}
  94

 127
 128 \func{void}{RecalcSizes}{\void}
 129
 130 Called when the managed size of the sizer is needed or when layout
 131 needs done.
 132
 133 \membersection{wxGridBagSizer::SetEmptyCellSize}\label{wxgridbagsizersetemptycellsize}
 134
 135 \func{void}{SetEmptyCellSize}{\param{const wxSize\& }{sz}}
 136

 144
 145 \func{bool}{SetItemPosition}{\param{size\_t }{index}, \param{const wxGBPosition\& }{pos}}
 146
 147 Set the grid position of the specified item. Returns true on success.
 148 If the move is not allowed (because an item is already there) then
 149 false is returned.
 150
 151 \membersection{wxGridBagSizer::SetItemSpan}\label{wxgridbagsizersetitemspan}
 152
 153 \func{bool}{SetItemSpan}{\param{wxWindow* }{window}, \param{const wxGBSpan\& }{span}}

 158
 159 Set the row/col spanning of the specified item. Returns true on
 160 success. If the move is not allowed (because an item is already there)
 161 then false is returned.
