\section{\class{wxStatusBar}}\label{wxstatusbar}

A status bar is a narrow window that can be placed along the bottom of a frame to give
small amounts of status information. It can contain one or more fields, one or more of which can
be variable length according to the size of the window.

\wxheading{Remarks}

It is possible to create controls and other windows on the status bar. Position these windows
from an {\bf OnSize} event handler.

\membersection{wxStatusBar::wxStatusBar}\label{wxstatusbarconstr}

\func{}{wxStatusBar}{\void}

Default constructor.

\func{}{wxStatusBar}{\param{wxWindow* }{parent}, \param{wxWindowID }{id},\rtfsp
\param{const wxPoint\&}{ pos = wxDefaultPosition},\rtfsp
\param{const wxSize\&}{ size = wxDefaultSize}, \param{long}{ style = 0},\rtfsp
\param{const wxString\& }{name = ``statusBar"}}

Constructor, creating the window.

\wxheading{Parameters}

\docparam{parent}{The window parent, usually a frame.}

\docparam{id}{The window identifier. It may take a value of -1 to indicate a default value.}

\docparam{pos}{The window position. A value of (-1, -1) indicates a default position, chosen by
either the windowing system or wxWindows, depending on platform.}

\docparam{size}{The window size. A value of (-1, -1) indicates a default size, chosen by
either the windowing system or wxWindows, depending on platform.}

\docparam{style}{The window style. See \helpref{wxStatusBar}{wxstatusbar}.}

\docparam{name}{The name of the window. This parameter is used to associate a name with the item,
allowing the application user to set Motif resource values for
individual windows.}

Returns the string associated with a status bar field.

\wxheading{Parameters}

\docparam{i}{The number of the status field to retrieve, starting from zero.}

\wxheading{Return value}

The status field string if the field is valid, otherwise the empty string.

\membersection{wxStatusBar::InitColours}\label{wxstatusbarinitcolours}

\func{virtual void}{InitColours}{\void}

Sets up the background colour and shading pens using suitable system colours (Windows) or tasteful shades
of grey (other platforms).

\wxheading{Remarks}

This function is called when the window is created, and also
from \helpref{wxStatusBar::OnSysColourChanged}{wxstatusbaronsyscolourchanged} on Windows.

\wxheading{See also}

\helpref{wxStatusBar::OnSysColourChanged}{wxstatusbaronsyscolourchanged}

\membersection{wxStatusBar::OnSysColourChanged}\label{wxstatusbaronsyscolourchanged}

\func{void}{OnSysColourChanged}{\param{wxSysColourChangedEvent\& }{event}}

Handles a system colour change by calling \helpref{wxStatusBar::InitColours}{wxstatusbarinitcolours},
and refreshes the window.

\wxheading{Parameters}

\docparam{event}{The colour change event.}

\membersection{wxStatusBar::SetFieldsCount}\label{wxstatusbarsetfieldscount}

\func{virtual void}{SetFieldsCount}{\param{int}{ number = 1}, \param{int* }{widths = NULL}}

Sets the number of fields, and optionally the field widths.

\pythonnote{Only the first parameter is accepted.  Use SetStatusWidths
to set the widths of the fields.}

\perlnote{In wxPerl this function acceps only the {\tt n} parameter.
Use SetStatusWidths to set the field widths.}

\wxheading{Parameters}

\docparam{number}{The number of fields.}

\docparam{widths}{An array of {\it n} integers, each of which is a status field width
in pixels. A value of -1 indicates that the field is variable width; at least one
field must be -1.}

\membersection{wxStatusBar::SetMinHeight}\label{wxstatusbarsetminheight}

\func{void}{SetMinHeight}{\param{int}{ height}}

Sets the minimal possible hight for the status bar. The real height may be
bigger than the height specified here depending on the size of the font used by
the status bar.

\membersection{wxStatusBar::SetStatusText}\label{wxstatusbarsetstatustext}

\func{virtual void}{SetStatusText}{\param{const wxString\& }{text}, \param{int}{ i = 0}}

Sets the text for one field.

\wxheading{Parameters}

\docparam{text}{The text to be set. Use an empty string (``") to clear the field.}

\docparam{i}{The field to set, starting from zero.}

\wxheading{See also}

\helpref{wxStatusBar::GetStatusText}{wxstatusbargetstatustext}, \helpref{wxFrame::SetStatusText}{wxframesetstatustext}

\membersection{wxStatusBar::SetStatusWidths}\label{wxstatusbarsetstatuswidths}

\func{virtual void}{SetStatusWidths}{\param{int}{ n}, \param{int *}{widths}}

Sets the widths of the fields in the status line.

\wxheading{Parameters}

\docparam{n}{The number of fields in the status bar.}

\docparam{widths}{Must contain an array of {\it n} integers, each of which is a status field width
in pixels. A value of -1 indicates that the field is variable width; at least one
field must be -1. You should delete this array after calling {\bf SetStatusWidths}.}

\wxheading{Remarks}

The widths of the variable fields are calculated from the total width of all fields,
minus the sum of widths of the non-variable fields, divided by the number of
variable fields.

integers.}
