\section{\class{wxFrame}}\label{wxframe}

A frame is a window whose size and position can (usually) be changed by the user. It usually has
thick borders and a title bar, and can optionally contain a menu bar, toolbar and
status bar. A frame can contain any window that is not a frame or dialog.

A frame that has a status bar and toolbar created via the CreateStatusBar/CreateToolBar functions
manages these windows, and adjusts the value returned by GetClientSize to reflect
the remaining size available to application windows.

\twocolitem{\windowstyle{wxFRAME\_FLOAT\_ON\_PARENT}}{Windows only. Causes the frame to be above the parent window in the
z-order and not shown in the taskbar. Without this style, frames are created as top-level windows that may be obscured by
the parent window, and frame titles are shown in the taskbar. On Motif and GTK, the behaviour is always as if this
style is not specified.}
\twocolitem{\windowstyle{wxFRAME\_TOOL\_WINDOW}}{Windows only. Causes a frame with a small titlebar to be created;
the frame title does not appear in the taskbar.}
\end{twocollist}

See also \helpref{window styles overview}{windowstyles}. Currently the GTK port of wxWindows
ignores all the window styles listed above as there is no standard way (yet) to inform the
window manager about such options. Therefore, the only relevant window style flag which
the GTK port recognizes is \windowstyle{wxSIMPLE\_BORDER} which brings up a frame without
any window decorations. This can be used for a splash screen or specialized tooltip etc.

\wxheading{Remarks}

An application should normally define an \helpref{OnCloseWindow}{wxwindowonclosewindow} handler for the
frame to respond to system close events, for example so that related data and subwindows can be cleaned up.

\membersection{wxFrame::wxFrame}\label{wxframeconstr}

\func{}{wxFrame}{\void}

Default constructor.

\func{}{wxFrame}{\param{wxWindow* }{parent}, \param{wxWindowID }{id},\rtfsp
\param{const wxString\& }{title}, \param{const wxPoint\&}{ pos = wxDefaultPosition},\rtfsp
\param{const wxSize\&}{ size = wxDefaultSize}, \param{long}{ style = wxDEFAULT\_FRAME\_STYLE},\rtfsp
\param{const wxString\& }{name = ``frame"}}

Constructor, creating the window.

\wxheading{Parameters}

\docparam{parent}{The window parent. This may be NULL. If it is non-NULL, the frame will
always be displayed on top of the parent window on Windows.}

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

\docparam{title}{The caption to be displayed on the frame's title bar.}

\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{wxFrame}{wxframe}.}

\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.}

\wxheading{Remarks}

For Motif, MWM (the Motif Window Manager) should be running for any window styles to work
(otherwise all styles take effect).

\membersection{wxFrame::CreateStatusBar}\label{wxframecreatestatusbar}

\func{virtual wxStatusBar*}{CreateStatusBar}{\param{int}{ number = 1},
 \param{long}{ style = 0},
 \param{wxWindowID}{ id = -1}, \param{const wxString\&}{ name = "statusBar"}}

Creates a status bar at the bottom of the frame.

\wxheading{Parameters}

\docparam{number}{The number of fields to create. Specify a
value greater than 1 to create a multi-field status bar.}

\docparam{style}{The status bar style. See \helpref{wxStatusBar}{wxstatusbar} for a list

wxWindows.}

\docparam{name}{The status bar window name.}

\wxheading{Return value}

A pointer to the the status bar if it was created successfully, NULL otherwise.

\wxheading{Remarks}

The width of the status bar is the whole width of the frame (adjusted automatically when
resizing), and the height and text size are chosen by the host windowing system.

By default, the status bar is an instance of wxStatusBar. To use a different class,
override \helpref{wxFrame::OnCreateStatusBar}{wxframeoncreatestatusbar}.

Note that you can put controls and other windows on the status bar if you wish.

\membersection{wxFrame::CreateToolBar}\label{wxframecreatetoolbar}

\func{virtual wxToolBar*}{CreateToolBar}{\param{long}{ style = wxNO\_BORDER \pipe wxTB\_HORIZONTAL},
 \param{wxWindowID}{ id = -1}, \param{const wxString\&}{ name = "toolBar"}}

\wxheading{Parameters}

\docparam{style}{The toolbar style. See \helpref{wxToolBar}{wxtoolbar} for a list
of valid styles.}

\docparam{id}{The toolbar window identifier. If -1, an identifier will be chosen by
wxWindows.}

\docparam{name}{The toolbar window name.}

\wxheading{Return value}

A pointer to the the toolbar if it was created successfully, NULL otherwise.

\wxheading{Remarks}

By default, the toolbar is an instance of wxToolBar (which is defined to be
a suitable toolbar class on each platform, such as wxToolBar95). To use a different class,
override \helpref{wxFrame::OnCreateToolBar}{wxframeoncreatetoolbar}.

When a toolbar has been created with this function, or made known to the frame
with \helpref{wxFrame::SetToolBar}{wxframesettoolbar}, the frame will manage the toolbar
position and adjust the return value from \helpref{wxWindow::GetClientSize}{wxwindowgetclientsize} to
reflect the available space for application windows.

Virtual function called when a toolbar is requested by \helpref{wxFrame::CreateToolBar}{wxframecreatetoolbar}.

\wxheading{Parameters}

\docparam{style}{The toolbar style. See \helpref{wxToolBar}{wxtoolbar} for a list
of valid styles.}

\docparam{id}{The toolbar window identifier. If -1, an identifier will be chosen by
wxWindows.}

\docparam{name}{The toolbar window name.}

\wxheading{Return value}

\wxheading{Remarks}

An application can override this function to return a different kind of toolbar. The default
implementation returns an instance of \helpref{wxToolBar}{wxtoolbar}.

\wxheading{See also}

\helpref{wxFrame::CreateToolBar}{wxframecreatetoolbar}, \helpref{wxToolBar}{wxtoolbar}.

\membersection{wxFrame::OnMenuCommand}\label{wxframeonmenucommand}

\func{void}{OnMenuCommand}{\param{wxCommandEvent\&}{ event}}

See \helpref{wxWindow::OnMenuCommand}{wxwindowonmenucommand}.

\membersection{wxFrame::OnMenuHighlight}\label{wxframeonmenuhighlight}

\func{void}{OnMenuHighlight}{\param{wxMenuEvent\&}{ event}}

See \helpref{wxWindow::OnMenuHighlight}{wxwindowonmenuhighlight}.

\membersection{wxFrame::OnSize}\label{wxframeonsize}

\func{void}{OnSize}{\param{wxSizeEvent\& }{event}}

See \helpref{wxWindow::OnSize}{wxwindowonsize}.

The default {\bf wxFrame::OnSize} implementation looks for a single subwindow,
and if one is found, resizes it to fit
inside the frame. Override this member if more complex behaviour
is required (for example, if there are several subwindows).

\membersection{wxFrame::SetIcon}\label{wxframeseticon}

\func{void}{SetIcon}{\param{const wxIcon\& }{icon}}

Sets the icon for this frame.

\wxheading{Parameters}

\docparam{icon}{The icon to associate with this frame.}

\wxheading{Remarks}

The frame takes a `copy' of {\it icon}, but since it uses reference
counting, the copy is very quick. It is safe to delete {\it icon} after
calling this function.

Under Windows, instead of using {\bf SetIcon}, you can add the
following lines to your MS Windows resource file:

\begin{verbatim}
wxSTD_MDIPARENTFRAME ICON icon1.ico
wxSTD_MDICHILDFRAME  ICON icon2.ico
wxSTD_FRAME          ICON icon3.ico
\end{verbatim}

where icon1.ico will be used for the MDI parent frame, icon2.ico
will be used for MDI child frames, and icon3.ico will be used for
non-MDI frames.

If these icons are not supplied, and {\bf SetIcon} is not called either,
then the following defaults apply if you have included wx.rc.

\begin{verbatim}
wxDEFAULT_FRAME               ICON std.ico
wxDEFAULT_MDIPARENTFRAME      ICON mdi.ico
wxDEFAULT_MDICHILDFRAME       ICON child.ico
\end{verbatim}

You can replace std.ico, mdi.ico and child.ico with your own defaults
for all your wxWindows application. Currently they show the same icon.

{\it Note:} a wxWindows application linked with subsystem equal to 4.0
(i.e. marked as a Windows 95 application) doesn't respond properly
to wxFrame::SetIcon. To work around this until a solution is found,
mark your program as a 3.5 application. This will also ensure
that Windows provides small icons for the application automatically.

See also \helpref{wxIcon}{wxicon}.

\membersection{wxFrame::SetMenuBar}\label{wxframesetmenubar}

\func{void}{SetMenuBar}{\param{wxMenuBar* }{menuBar}}

Tells the frame to show the given menu bar.

\wxheading{Parameters}

\docparam{menuBar}{The menu bar to associate with the frame.}

\wxheading{Remarks}

If the frame is destroyed, the
menu bar and its menus will be destroyed also, so do not delete the menu
bar explicitly (except by resetting the frame's menu bar to another
frame or NULL).

Under Windows, a call to \helpref{wxFrame::OnSize}{wxframeonsize} is generated, so be sure to initialize
data members properly before calling {\bf SetMenuBar}.

Note that it is not possible to call this function twice for the same frame object.

\membersection{wxFrame::SetStatusBar}\label{wxframesetstatusbar}

\func{void}{SetStatusBar}{\param{wxStatusBar*}{ statusBar}}

Associates a status bar with the frame.

\membersection{wxFrame::SetStatusText}\label{wxframesetstatustext}

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

Sets the status bar text and redraws the status bar.

\wxheading{Parameters}

\docparam{text}{The text for the status field.}

\docparam{number}{The status field (starting from zero).}

\wxheading{Remarks}

Use an empty string to clear the status bar.

\membersection{wxFrame::SetStatusWidths}\label{wxframesetstatuswidths}

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

Sets the widths of the fields in the status bar.

\wxheading{Parameters}

\wxheading{n}{The number of fields in the status bar. It must be the
same used in \helpref{CreateStatusBar}{wxframecreatestatusbar}.}

\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.

\membersection{wxFrame::SetToolBar}\label{wxframesettoolbar}

\func{void}{SetToolBar}{\param{wxToolBar*}{ toolBar}}
