\section{\class{wxTipWindow}}\label{wxtipwindow}

Shows simple text in a popup tip window on creation. This is used by 
\helpref{wxSimpleHelpProvider}{wxsimplehelpprovider} to show popup help. The
window automatically destroys itself when the user clicks on it or it loses the
focus.

You may also use this class to emulate the tooltips when you need finer
control over them than what the standard tooltips provide.

\membersection{wxTipWindow::wxTipWindow}\label{wxtipwindowwxtipwindow}

\func{}{wxTipWindow}{\param{wxWindow* }{parent}, \param{const wxString\& }{text}, \param{wxCoord }{maxLength = 100}, \param{wxTipWindow** }{windowPtr}, \param{wxRect *}{rectBounds = \NULL}}

Constructor. The tip is shown immediately after the window is constructed.

\wxheading{Parameters}

\docparam{parent}{The parent window, must be non-\NULL}

\docparam{text}{The text to show, may contain the new line characters}

\docparam{maxLength}{The length of each line, in pixels. Set to a very large
value to avoid wrapping lines}

\docparam{windowPtr}{Simply passed to 
\helpref{SetTipWindowPtr}{wxtipwindowsettipwindowptr} below, please see its
documentation for the description of this parameter}

\docparam{rectBounds}{If non-\NULL, passed to 
\helpref{SetBoundingRect}{wxtipwindowsetboundingrect} below, please see its
documentation for the description of this parameter}



\membersection{wxTipWindow::SetTipWindowPtr}\label{wxtipwindowsettipwindowptr}

\func{void}{SetTipWindowPtr}{\param{wxTipWindow** }{windowPtr}}

When the tip window closes itself (which may happen at any moment and
unexpectedly to the caller) it may \NULL out the pointer pointed to by 
\arg{it windowPtr}. This is helpful to avoid dereferencing the tip window which
had been already closed and deleted.



\membersection{wxTipWindow::SetBoundingRect}\label{wxtipwindowsetboundingrect}

\func{void}{SetBoundingRect}{\param{const wxRect\& }{rectBound}}

By default, the tip window disappears when the user clicks the mouse or presses
a keyboard key or if it loses focus in any other way - for example because the
user switched to another application window.

Additionally, if a non-empty \arg{rectBound} is provided, the tip window will
also automatically close if the mouse leaves this area. This is useful to
dismiss the tip mouse when the mouse leaves the object it is associated with.

\wxheading{Parameters}

\docparam{rectBound}{The bounding rectangle for the mouse in the screen coordinates}
