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

\func{}{wxFlexGridSizer}{\param{int }{rows}, \param{int }{cols}, \param{int }{vgap}, \param{int }{hgap}}
|
|
|
|
\func{}{wxFlexGridSizer}{\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.
|
|
|
|
|
|
\membersection{wxFlexGridSizer::AddGrowableCol}\label{wxflexgridsizeraddgrowablecol}
|
|
|
|
\func{void}{AddGrowableCol}{\param{size\_t }{idx}}
|
|
|
|
Specifies that column idx (starting from zero) should be grown if
|
|
there is extra space available to the sizer.
|
|
|
|
\membersection{wxFlexGridSizer::AddGrowableRow}\label{wxflexgridsizeraddgrowablerow}
|
|
|
|
\func{void}{AddGrowableRow}{\param{size\_t }{idx}}
|
|
|
|
Specifies that row idx (starting from zero) should be grown if there
|
|
is extra space available to the sizer.
|
|
|
|
\membersection{wxFlexGridSizer::GetFlexibleDirection}\label{wxflexgridsizergetflexibledrection}
|
|
|
|
\constfunc{int}{GetFlexibleDirections}{\void}
|
|
|
|
Returns a wxOrientation value that specifies whether the sizer flexibly
|
|
resizes its columns, rows, or both (default).
|
|
|
|
\wxheading{Return value}
|
|
|
|
One of the following values:
|
|
|
|
\begin{twocollist}
|
|
\twocolitem{wxVERTICAL}{Rows are flexibly sized.}
|
|
\twocolitem{wxHORIZONTAL}{Columns are flexibly sized.}
|
|
\twocolitem{wxBOTH}{Both rows and columns are flexibly sized (this is the default value).}

|
|
|
|
\constfunc{int}{GetNonFlexibleGrowMode}{\void}
|
|
|
|
Returns the value that specifies how the sizer grows in the "non flexible"
|
|
direction if there is one.
|
|
|
|
\wxheading{Return value}
|
|
|
|
One of the following values:
|
|
|
|
\begin{twocollist}
|
|
\twocolitem{wxFLEX\_GROWMODE\_NONE}{Sizer doesn't grow in the non flexible direction.}
|
|
\twocolitem{wxFLEX\_GROWMODE\_SPECIFIED}{Sizer honors growable columns/rows set with
|
|
\helpref{AddGrowableCol}{wxflexgridsizeraddgrowablecol} and
|
|
\helpref{AddGrowableRow}{wxflexgridsizeraddgrowablerow}.
|
|
In this case equal sizing applies to minimum sizes of columns or
|
|
rows (this is the default value).}
|
|
\twocolitem{wxFLEX\_GROWMODE\_ALL}{Sizer equally stretches all columns or rows
|
|
in the non flexible direction, whether they are growable or not in the flexbile
|
|
direction.}
|

\membersection{wxFlexGridSizer::RemoveGrowableCol}\label{wxflexgridsizerremovegrowablecol}
|
|
|
|
\func{void}{RemoveGrowableCol}{\param{size\_t }{idx}}
|
|
|
|
Specifies that column idx is no longer growable.

|
\membersection{wxFlexGridSizer::RemoveGrowableRow}\label{wxflexgridsizerremovegrowablerow}
|
|
|
|
\func{void}{RemoveGrowableRow}{\param{size\_t }{idx}}
|
|
|
|
Specifies that row idx is no longer growable.
|
|
|
|
|
|
\membersection{wxFlexGridSizer::SetFlexibleDirection}\label{wxflexgridsizersetflexibledirection}
|
|
|
|
\func{void}{SetFlexibleDirections}{\param{int }{direction}}
|
|
|
|
Specifies whether the sizer should flexibly resize its columns, rows, or
|
|
both. Argument {\tt direction} can be {\tt wxVERTICAL}, {\tt wxHORIZONTAL}
|
|
or {\tt wxBOTH} (which is the default value). Any other value is ignored. See
|
|
\helpref{GetFlexibleDirection()}{wxflexgridsizergetflexibledrection} for the
|
|
explanation of these values.
|
|
|
|
Note that this method does not trigger relayout.

\membersection{wxFlexGridSizer::SetNonFlexibleGrowMode}\label{wxflexgridsizersetnonflexiblegrowmode}
|
|
|
|
\func{void}{SetNonFlexibleGrowMode}{\param{int }{mode}}
|
|
|
|
Specifies how the sizer should grow in the non flexible direction if
|
|
there is one (so
|
|
\helpref{SetFlexibleDirections()}{wxflexgridsizersetflexibledirection} must have
|
|
been called previously). Argument {\it mode} can be one of those documented in
|
|
\helpref{GetNonFlexibleGrowMode}{wxflexgridsizergetnonflexiblegrowmode}, please
|
|
see there for their explanation.
|
|
|

Note that this method does not trigger relayout.
