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.

Window styles
wxICONIZE | Display the frame iconized (minimized) (Windows only). |
wxCAPTION | Puts a caption on the frame. |
wxDEFAULT_FRAME_STYLE | Defined as wxMINIMIZE_BOX | wxMAXIMIZE_BOX | wxTHICK_FRAME | wxSYSTEM_MENU | wxCAPTION. |
wxMINIMIZE | Identical to wxICONIZE. |
wxMINIMIZE_BOX | Displays a minimize box on the frame (Windows and Motif only). |
wxMAXIMIZE | Displays the frame maximized (Windows only). |
wxMAXIMIZE_BOX | Displays a maximize box on the frame (Windows and Motif only). |
wxSTAY_ON_TOP | Stay on top of other windows (Windows only). |
wxSYSTEM_MENU | Displays a system menu (Windows and Motif only). |
wxTHICK_FRAME | Displays a thick frame around the window (Windows and Motif only). |
wxRESIZE_BORDER | Displays a resizeable border around the window (Motif only). |
See also window styles overview. 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 wxSIMPLE_BORDER which brings up a frame without any window decorations. This can be used for a splash screen or specialized tooltip etc.
Remarks
An application should normally define an OnCloseWindow handler for the frame to respond to system close events, for example so that related data and subwindows can be cleaned up.

wxFrame()
Default constructor.
wxFrame(wxWindow* parent, wxWindowID id, const wxString& title, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxDEFAULT_FRAME_STYLE, const wxString& name = "frame")
Constructor, creating the window.
Parameters
parent
id
title
pos
size
style
name
Remarks
For Motif, MWM (the Motif Window Manager) should be running for any window styles to work (otherwise all styles take effect).

void ~wxFrame()
Destructor. Destroys all child windows and menu bar if present.
void Centre(int direction = wxBOTH)
Centres the frame on the display.
Parameters
direction
void Command(int id)
Simulate a menu command.
Parameters
id
bool Create(wxWindow* parent, wxWindowID id, const wxString& title, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxDEFAULT_FRAME_STYLE, const wxString& name = "frame")
Used in two-step frame construction. See wxFrame::wxFrame for further details.
virtual wxStatusBar* CreateStatusBar(int number = 1, long style = 0, wxWindowID id = -1, const wxString& name = "statusBar")
Creates a status bar at the bottom of the frame.
Parameters
number
style
id
name
Return value
A pointer to the the status bar if it was created successfully, NULL otherwise.
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 wxFrame::OnCreateStatusBar.
Note that you can put controls and other windows on the status bar if you wish.

wxFrame::SetStatusText, wxFrame::OnCreateStatusBar, wxFrame::GetStatusBar
virtual wxToolBar* CreateToolBar(long style = wxNO_BORDER | wxTB_HORIZONTAL, wxWindowID id = -1, const wxString& name = "toolBar")
Creates a toolbar at the top or left of the frame.
Parameters
style
id
name
Return value
A pointer to the the toolbar if it was created successfully, NULL otherwise.
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 wxFrame::OnCreateToolBar.
When a toolbar has been created with this function, or made known to the frame with wxFrame::SetToolBar, the frame will manage the toolbar position and adjust the return value from wxWindow::GetClientSize to reflect the available space for application windows.

wxFrame::CreateStatusBar, wxStatusBar
wxString& GetTitle()
Gets a temporary pointer to the frame title. See wxFrame::SetTitle.
wxToolBar* GetToolBar()
Returns a pointer to the toolbar currently associated with the frame (if any).

void Iconize(const bool iconize)
Iconizes or restores the frame.
Parameters
izonize
See also
wxFrame::IsIconized, wxFrame::Maximize.
bool IsIconized() const
Returns TRUE if the frame is iconized.
bool IsMaximized() const
Returns TRUE if the frame is maximized.
void Maximize(const bool maximize)
Maximizes or restores the frame.
Parameters
maximize
Remarks
This function only works under Windows.
See also
void OnActivate(wxActivateEvent& event)
Called when a window is activated or deactivated (MS Windows only). See also wxActivateEvent.
virtual wxStatusBar* OnCreateStatusBar(int number, long style, wxWindowID id, const wxString& name)
Virtual function called when a status bar is requested by wxFrame::CreateStatusBar.
Parameters
number
style
id
name
Return value
A status bar object.
Remarks
An application can override this function to return a different kind of status bar. The default implementation returns an instance of wxStatusBar.
See also
wxFrame::CreateStatusBar, wxStatusBar.
virtual wxToolBar* OnCreateToolBar(long style, wxWindowID id, const wxString& name)
Virtual function called when a toolbar is requested by wxFrame::CreateToolBar.
Parameters
style
id
name
Return value
A toolbar object.
Remarks
An application can override this function to return a different kind of toolbar. The default implementation returns an instance of wxToolBar.
See also
wxFrame::CreateToolBar, wxToolBar.
void OnMenuCommand(wxCommandEvent& event)
void OnMenuHighlight(wxMenuEvent& event)
See wxWindow::OnMenuHighlight.
void OnSize(wxSizeEvent& event)
See wxWindow::OnSize.
The default 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).
void SetIcon(const wxIcon& icon)
Sets the icon for this frame.
Parameters
icon
Remarks
The frame takes a 'copy' of icon, but since it uses reference counting, the copy is very quick. It is safe to delete icon after calling this function.
Under Windows, instead of using SetIcon, you can add the following lines to your MS Windows resource file:
wxSTD_MDIPARENTFRAME ICON icon1.ico wxSTD_MDICHILDFRAME ICON icon2.ico wxSTD_FRAME ICON icon3.icowhere 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 SetIcon is not called either, then the following defaults apply if you have included wx.rc.
wxDEFAULT_FRAME ICON std.ico wxDEFAULT_MDIPARENTFRAME ICON mdi.ico wxDEFAULT_MDICHILDFRAME ICON child.icoYou can replace std.ico, mdi.ico and child.ico with your own defaults for all your wxWindows application. Currently they show the same icon.
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 wxIcon.
void SetMenuBar(wxMenuBar* menuBar)
Tells the frame to show the given menu bar.
Parameters
menuBar
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 wxFrame::OnSize is generated, so be sure to initialize data members properly before calling SetMenuBar.
Note that it is not possible to call this function twice for the same frame object.

wxFrame::GetMenuBar, wxMenuBar, wxMenu.
void SetStatusBar(wxStatusBar* statusBar)
Associates a status bar with the frame.
See also
wxFrame::CreateStatusBar, wxStatusBar, wxFrame::GetStatusBar

number
Remarks
Use an empty string to clear the status bar.

virtual void SetStatusWidths(int n, int *widths)
Sets the widths of the fields in the status bar.
Parameters
nThe number of fields in the status bar. It must be the same used in CreateStatusBar.
widths
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.
void SetToolBar(wxToolBar* toolBar)
Associates a toolbar with the frame.
See also
wxFrame::CreateToolBar, wxToolBar, wxFrame::GetToolBar
