   6 \section{\class{wxHtmlContainerCell}}\label{wxhtmlcontainercell}
   7
   8 The wxHtmlContainerCell class is an implementation of a cell that may
   9 contain more cells in it. It is heavily used in the wxHTML layout algorithm.

  21 \membersection{wxHtmlContainerCell::wxHtmlContainerCell}\label{wxhtmlcontainercellwxhtmlcontainercell}
  22
  23 \func{}{wxHtmlContainerCell}{\param{wxHtmlContainerCell }{*parent}}
  24
  25 Constructor. {\it parent} is pointer to parent container or NULL.
  26
  27
  28 \membersection{wxHtmlContainerCell::GetAlignHor}\label{wxhtmlcontainercellgetalignhor}
  29
  30 \constfunc{int}{GetAlignHor}{\void}
  31
  32 Returns container's horizontal alignment.
  33
  34 \membersection{wxHtmlContainerCell::GetAlignVer}\label{wxhtmlcontainercellgetalignver}
  35
  36 \constfunc{int}{GetAlignVer}{\void}
  37
  38 Returns container's vertical alignment.
  39
  40 \membersection{wxHtmlContainerCell::GetFirstCell}\label{wxhtmlcontainercellgetfirstcell}
  41
  42 \func{wxHtmlCell*}{GetFirstCell}{\void}
  43
  44 Returns pointer to the first cell in the list.
  45 You can then use wxHtmlCell's GetNext method to obtain pointer to the next
  46 cell in list.
  47
  48 {\bf Note:} This shouldn't be used by the end user. If you need some way of
  49 finding particular cell in the list, try \helpref{Find}{wxhtmlcellfind} method
  50 instead.
  51
  52 \membersection{wxHtmlContainerCell::GetIndent}\label{wxhtmlcontainercellgetindent}
  53
  54 \constfunc{int}{GetIndent}{\param{int }{ind}}
  55
  56 Returns the indentation. {\it ind} is one of the {\bf HTML\_INDENT\_*} constants.
  57
  58 {\bf Note:} You must call \helpref{GetIndentUnits}{wxhtmlcontainercellgetindentunits}
  59 with same {\it ind} parameter in order to correctly interpret the returned integer value.
  60 It is NOT always in pixels!
  61
  62 \membersection{wxHtmlContainerCell::GetIndentUnits}\label{wxhtmlcontainercellgetindentunits}
  63
  64 \constfunc{int}{GetIndentUnits}{\param{int }{ind}}
  65
  66 Returns the units of indentation for {\it ind} where {\it ind} is one
  67 of the {\bf HTML\_INDENT\_*} constants.
  68
  69 \membersection{wxHtmlContainerCell::GetMaxLineWidth}\label{wxhtmlcontainercellgetmaxlinewidth}
  70
  71 \constfunc{int}{GetMaxLineWidth}{\void}
  72
  73 Returns width of widest line (note : this may be more than GetWidth()!!
  74 E.g. if you have 640x480 image and the wxHtmlWindow is only 100x100...)
  75
  76 Call to this method is valid only after calling \helpref{Layout}{wxhtmlcelllayout}
  77
  78 \membersection{wxHtmlContainerCell::InsertCell}\label{wxhtmlcontainercellinsertcell}
  79
  80 \func{void}{InsertCell}{\param{wxHtmlCell }{*cell}}
  81
  82 Inserts new cell into the container.
  83
  84 \membersection{wxHtmlContainerCell::SetAlign}\label{wxhtmlcontainercellsetalign}
  85
  86 \func{void}{SetAlign}{\param{const wxHtmlTag\& }{tag}}
  87
  88 Sets the container's alignment (both horizontal and vertical) according to
  89 the values stored in {\it tag}. (Tags {\tt ALIGN} parameter is extracted.) In fact
  90 it is only a front-end to \helpref{SetAlignHor}{wxhtmlcontainercellsetalignhor}
  91 and \helpref{SetAlignVer}{wxhtmlcontainercellsetalignver}.
  92
  93 \membersection{wxHtmlContainerCell::SetAlignHor}\label{wxhtmlcontainercellsetalignhor}
  94
  95 \func{void}{SetAlignHor}{\param{int }{al}}
  96
  97 Sets the container's {\it horizontal alignment}. During \helpref{Layout}{wxhtmlcelllayout}
  98 each line is aligned according to {\it al} value.
  99
 100 \wxheading{Parameters}
 101
 102 \docparam{al}{new horizontal alignment. May be one of these values:
 103
 104 \begin{twocollist}\itemsep=0pt
 105 \twocolitem{{\bf HTML\_ALIGN\_LEFT}}{lines are left-aligned (default)}
 106 \twocolitem{{\bf HTML\_ALIGN\_CENTER\_H}}{lines are centered}
 107 \twocolitem{{\bf HTML\_ALIGN\_RIGHT}}{lines are right-aligned}
 108 \end{twocollist}
 109 }
 110
 111 \membersection{wxHtmlContainerCell::SetAlignVer}\label{wxhtmlcontainercellsetalignver}
 112
 113 \func{void}{SetAlignVer}{\param{int }{al}}
 114
 115 Sets the container's {\it vertical alignment}. This is per-line alignment!
 116
 117 \wxheading{Parameters}
 118
 119 \docparam{al}{new vertical alignment. May be one of these values:
 120
 121 \begin{twocollist}\itemsep=0pt
 122 \twocolitem{{\bf HTML\_ALIGN\_BOTTOM}}{cells are over the line (default)}
 123 \twocolitem{{\bf HTML\_ALIGN\_CENTER\_V}}{cells are centered on line}
 124 \twocolitem{{\bf HTML\_ALIGN\_TOP}}{cells are under the line}
 125 \end{twocollist}

 133
 134 Sets the background color for this container.
 135
 136 \membersection{wxHtmlContainerCell::SetBorder}\label{wxhtmlcontainercellsetborder}
 137
 138 \func{void}{SetBorder}{\param{const wxColour\& }{clr1}, \param{const wxColour\& }{clr2}}

 145
 146 \docparam{clr2}{Color of bottom and right lines}

 149
 150 \func{void}{SetIndent}{\param{int }{i}, \param{int }{what}, \param{int }{units = HTML\_UNITS\_PIXELS}}
 151
 152 Sets the indentation (free space between borders of container and subcells).
 153
 154 \wxheading{Parameters}
 155
 156 \docparam{i}{Indentation value.}
 157
 158 \docparam{what}{Determines which of the four borders we're setting. It is OR
 159 combination of following constants:
 160
 161 \begin{twocollist}\itemsep=0pt
 162 \twocolitem{{\bf HTML\_INDENT\_TOP}}{top border}
 163 \twocolitem{{\bf HTML\_INDENT\_BOTTOM}}{bottom}

 171 \helponly{\image{}{indent.bmp}}
 172 }
 173
 174 \docparam{units}{Units of {\it i}. This parameter affects interpretation of {\it} value.
 175
 176 \begin{twocollist}\itemsep=0pt
 177 \twocolitem{{\bf HTML\_UNITS\_PIXELS}}{{\it i} is number of pixels}
 178 \twocolitem{{\bf HTML\_UNITS\_PERCENT}}{{\it i} is interpreted as percents of width
 179 of parent container}
 180 \end{twocollist}
 181 }
 182
 183 \membersection{wxHtmlContainerCell::SetMinHeight}\label{wxhtmlcontainercellsetminheight}
 184
 185 \func{void}{SetMinHeight}{\param{int }{h}, \param{int }{align = HTML\_ALIGN\_TOP}}
 186
 187 Sets minimal height of the container.
 188
 189 When container's \helpref{Layout}{wxhtmlcelllayout} is called, m\_Height
 190 is set depending on layout of subcells to the height of area covered
 191 by layed-out subcells. Calling this method guarantees you that the height
 192 of container is never smaller than {\it h} - even if the subcells cover
 193 much smaller area.
 194
 195 \wxheading{Parameters}
 196
 197 \docparam{h}{The minimal height.}
 198
 199 \docparam{align}{If height of the container is lower than the minimum height, empty space must be inserted
 200 somewhere in order to ensure minimal height. This parameter is one of {\bf HTML\_ALIGN\_TOP,
 201 HTML\_ALIGN\_BOTTOM, HTML\_ALIGN\_CENTER} constants. It refers to the {\it contents}, not to the
 202 empty place!}
 203
 204 \membersection{wxHtmlContainerCell::SetWidthFloat}\label{wxhtmlcontainercellsetwidthfloat}
 205
 206 \func{void}{SetWidthFloat}{\param{int }{w}, \param{int }{units}}
 207
 208 \func{void}{SetWidthFloat}{\param{const wxHtmlTag\& }{tag}, \param{double }{pixel\_scale = 1.0}}
 209
 210 Sets floating width adjustment.
 211
 212 The normal behaviour of container is that its width is the same as the width of
 213 parent container (and thus you can have only one sub-container per line).
 214 You can change this by setting FWA.
 215
 216 {\it pixel\_scale} is number of real pixels that equals to 1 HTML pixel.
 217
 218 \wxheading{Parameters}
 219
 220 \docparam{w}{Width of the container. If the value is negative it means
 221 complement to full width of parent container (e.g.
 222 {\tt SetWidthFloat(-50, HTML\_UNITS\_PIXELS)} sets the width
 223 of container to parent's width minus 50 pixels. This is useful when
 224 creating tables - you can call SetWidthFloat(50) and SetWidthFloat(-50))}
 225
 226 \docparam{units}{Units of {\it w} This parameter affects the interpretation of {\it} value.
 227
 228 \begin{twocollist}\itemsep=0pt
 229 \twocolitem{{\bf HTML\_UNITS\_PIXELS}}{{\it w} is number of pixels}
 230 \twocolitem{{\bf HTML\_UNITS\_PERCENT}}{{\it w} is interpreted as percents of width
 231 of parent container}
 232 \end{twocollist}
 233 }
 234
 235 \docparam{tag}{In the second version of method, {\it w} and {\it units}
 236 info is extracted from tag's {\tt WIDTH} parameter.}
 237
 238 \pythonnote{The second form of this method is named
 239 SetWidthFloatFromTag in wxPython.}
