\section{\class{wxQueryLayoutInfoEvent}}\label{wxquerylayoutinfoevent}
This event is sent when \helpref{wxLayoutAlgorithm}{wxlayoutalgorithm} wishes to get
the size, orientation and alignment of a window. More precisely, the event is sent
by the OnCalculateLayout handler which is itself invoked by wxLayoutAlgorithm.

\membersection{wxQueryLayoutInfoEvent::wxQueryLayoutInfoEvent}\label{wxquerylayoutinfoeventctor}
\func{}{wxQueryLayoutInfoEvent}{\param{wxWindowID }{id = 0}}
Constructor.
\membersection{wxQueryLayoutInfoEvent::GetAlignment}\label{wxquerylayoutinfoeventgetalignment}
\constfunc{void}{GetAlignment}{\void}
Specifies the alignment of the window (which side of the remaining parent client area
the window sticks to). One of wxLAYOUT\_TOP, wxLAYOUT\_LEFT, wxLAYOUT\_RIGHT, wxLAYOUT\_BOTTOM.
\membersection{wxQueryLayoutInfoEvent::GetFlags}\label{wxquerylayoutinfoeventgetflags}
\constfunc{int}{GetFlags}{\void}
Returns the flags associated with this event. Not currently used.
\membersection{wxQueryLayoutInfoEvent::GetOrientation}\label{wxquerylayoutinfoeventgetorientation}
\constfunc{wxLayoutOrientation}{GetOrientation}{\void}
Returns the orientation that the event handler specified to the event object. May be one of wxLAYOUT\_HORIZONTAL,
wxLAYOUT\_VERTICAL.
\membersection{wxQueryLayoutInfoEvent::GetRequestedLength}\label{wxquerylayoutinfoeventgetrequestedlength}
\constfunc{int}{GetRequestedLength}{\void}
Returns the requested length of the window in the direction of the window orientation. This information
is not yet used.
\membersection{wxQueryLayoutInfoEvent::GetSize}\label{wxquerylayoutinfoeventgetsize}
\constfunc{wxSize}{GetSize}{\void}
Returns the size that the event handler specified to the event object as being the requested size of the window.
\membersection{wxQueryLayoutInfoEvent::SetAlignment}\label{wxquerylayoutinfoeventsetalignment}
\func{void}{SetAlignment}{\param{wxLayoutAlignment }{alignment}}
Call this to specify the alignment of the window (which side of the remaining parent client area
the window sticks to). May be one of wxLAYOUT\_TOP, wxLAYOUT\_LEFT, wxLAYOUT\_RIGHT, wxLAYOUT\_BOTTOM.
\membersection{wxQueryLayoutInfoEvent::SetFlags}\label{wxquerylayoutinfoeventsetflags}
\func{void}{SetFlags}{\param{int }{flags}}
Sets the flags associated with this event. Not currently used.
\membersection{wxQueryLayoutInfoEvent::SetOrientation}\label{wxquerylayoutinfoeventsetorientation}
\func{void}{SetOrientation}{\param{wxLayoutOrientation }{orientation}}
Call this to specify the orientation of the window. May be one of wxLAYOUT\_HORIZONTAL,
wxLAYOUT\_VERTICAL.
\membersection{wxQueryLayoutInfoEvent::SetRequestedLength}\label{wxquerylayoutinfoeventsetrequestedlength}
\func{void}{SetRequestedLength}{\param{int}{ length}}
Sets the requested length of the window in the direction of the window orientation. This information
is not yet used.
\membersection{wxQueryLayoutInfoEvent::SetSize}\label{wxquerylayoutinfoeventsetsize}
\func{void}{SetSize}{\param{const wxSize\& }{size}}
Call this to let the calling code know what the size of the window is.
