\section{\class{wxGridSizer}}\label{wxgridsizer} A grid sizer is a sizer which lays out its children in a two-dimensional table with all table fields having the same size, i.e. the width of each field is the width of the widest child, the height of each field is the height of the tallest child. \wxheading{Derived from} \helpref{wxSizer}{wxsizer}\\ \helpref{wxObject}{wxobject} \membersection{wxGridSizer::wxGridSizer}\label{wxgridsizerwxgridsizer} \func{}{wxGridSizer}{\param{int }{cols}, \param{int }{rows}, \param{int }{vgap}, \param{int }{hgap}} \func{}{wxGridSizer}{\param{int }{cols}, \param{int }{vgap = 0}, \param{int }{hgap = 0}} Constructor for a wxGridSizer. {\it rows} and {\it cols} determine the number of columns and rows in the sizer - if either of the parameters is zero, it will be calculated to form the total number of children in the sizer, thus making the sizer grow dynamically. {\it vgap} and {\it hgap} define extra space between all children.
