wx.Frame

 Default event processing

wx.Frame processes the following events:

• wxEVT_SIZE: if the frame has exactly one child window, not counting the status and toolbar, this child is resized to take the entire frame client area. If two or more windows are present, they should be laid out explicitly either by manually handling wxEVT_SIZE or using sizers;
• wxEVT_MENU_HIGHLIGHT: the default implementation displays the help string associated with the selected item in the first pane of the status bar, if there is one.

 Window Styles

This class supports the following styles:

• wx.DEFAULT_FRAME_STYLE: Defined as wx.MINIMIZE_BOX | wx.MAXIMIZE_BOX | wx.RESIZE_BORDER | wx.SYSTEM_MENU | wx.CAPTION | wx.CLOSE_BOX | wx.CLIP_CHILDREN.
• wx.ICONIZE: Display the frame iconized (minimized). Windows only.
• wx.CAPTION: Puts a caption on the frame. Notice that this flag is required by wx.MINIMIZE_BOX, wx.MAXIMIZE_BOX and wx.CLOSE_BOX on most systems as the corresponding buttons cannot be shown if the window has no title bar at all. I.e. if wx.CAPTION is not specified those styles would be simply ignored.
• wx.MINIMIZE: Identical to wx.ICONIZE. Windows only.
• wx.MINIMIZE_BOX: Displays a minimize box on the frame.
• wx.MAXIMIZE: Displays the frame maximized. Windows and GTK+ only.
• wx.MAXIMIZE_BOX: Displays a maximize box on the frame. Notice that under wxGTK wx.RESIZE_BORDER must be used as well or this style is ignored.
• wx.CLOSE_BOX: Displays a close box on the frame.
• wx.STAY_ON_TOP: Stay on top of all other windows, see also wx.FRAME_FLOAT_ON_PARENT.
• wx.SYSTEM_MENU: Displays a system menu containing the list of various windows commands in the window title bar. Unlike wx.MINIMIZE_BOX, wx.MAXIMIZE_BOX and wx.CLOSE_BOX styles this style can be used withoutwx.CAPTION, at least under Windows, and makes the system menu available without showing it on screen in this case. However it is recommended to only use it together with wx.CAPTION for consistent behaviour under all platforms.
• wx.RESIZE_BORDER: Displays a resizable border around the window.
• wx.FRAME_TOOL_WINDOW: Causes a frame with a small title bar to be created; the frame does not appear in the taskbar under Windows or GTK+.
• wx.FRAME_NO_TASKBAR: Creates an otherwise normal frame but it does not appear in the taskbar under Windows or GTK+ (note that it will minimize to the desktop window under Windows which may seem strange to the users and thus it might be better to use this style only without wx.MINIMIZE_BOX style). In wxGTK, the flag is respected only if the window manager supports _NET_WM_STATE_SKIP_TASKBAR hint.
• wx.FRAME_FLOAT_ON_PARENT: The frame will always be on top of its parent (unlike wx.STAY_ON_TOP). A frame created with this style must have a not None parent.
• wx.FRAME_SHAPED: Windows with this style are allowed to have their shape changed with the SetShape method.

The default frame style is for normal, resizable frames. To create a frame which cannot be resized by user, you may use the following combination of styles:

style = wx.DEFAULT_FRAME_STYLE & ~(wx.RESIZE_BORDER | wx.MAXIMIZE_BOX)

 Window Extra Styles

See also the Window Styles. This class supports the following extra styles:

• wx.FRAME_EX_CONTEXTHELP: Under Windows, puts a query button on the caption. When pressed, Windows will go into a context-sensitive help mode and wxWidgets will send a wxEVT_HELP event if the user clicked on an application window. Note that this is an extended style and must be set by calling SetExtraStyle before Create is called (two-step construction). You cannot use this style together with wx.MAXIMIZE_BOX orwx.MINIMIZE_BOX, so you should use wx.DEFAULT_FRAME_STYLE ~ (wx``wx.MINIMIZE_BOX`` | wx.MAXIMIZE_BOX) for the frames having this style (the dialogs don’t have a minimize or a maximize box by default)
• wx.FRAME_EX_METAL: On Mac OS X, frames with this style will be shown with a metallic look. This is an extra style.

 Events Emitted by this Class

Event macros for events emitted by this class:

• EVT_CLOSE: Process a wxEVT_CLOSE_WINDOW event when the frame is being closed by the user or programmatically (see wx.Window.Close ). The user may generate this event clicking the close button (typically the ‘X’ on the top-right of the title bar) if it’s present (see the CLOSE_BOX style). See wx.CloseEvent.
• EVT_ICONIZE: Process a wxEVT_ICONIZE event. See wx.IconizeEvent.
• EVT_MENU_OPEN: A menu is about to be opened. See wx.MenuEvent.
• EVT_MENU_CLOSE: A menu has been just closed. See wx.MenuEvent.
• EVT_MENU_HIGHLIGHT: The menu item with the specified id has been highlighted: used to show help prompts in the status bar by wx.Frame. See wx.MenuEvent.
• EVT_MENU_HIGHLIGHT_ALL: A menu item has been highlighted, i.e. the currently selected menu item has changed. See wx.MenuEvent.

 Class API

class wx.Frame(TopLevelWindow)

Possible constructors:

Frame()

Frame(parent, id=ID_ANY, title="", pos=DefaultPosition,
      size=DefaultSize, style=DEFAULT_FRAME_STYLE, name=FrameNameStr)

A frame is a window whose size and position can (usually) be changed by the user.

Methods

---

__init__(self, *args, **kw)

 Overloaded Implementations:

 

---

 

__init__ (self)

Default constructor.

 

---

 

__init__ (self, parent, id=ID_ANY, title=””, pos=DefaultPosition, size=DefaultSize, style=DEFAULT_FRAME_STYLE, name=FrameNameStr)

Constructor, creating the window.

Parameters:

parent (wx.Window) – The window parent. This may be, and often is, None. If it is not None, the frame will be minimized when its parent is minimized and restored when it is restored (although it will still be possible to minimize and restore just this frame itself). id (wx.WindowID) – The window identifier. It may take a value of -1 to indicate a default value. title (string) – The caption to be displayed on the frame’s title bar. pos (wx.Point) – The window position. The value DefaultPosition indicates a default position, chosen by either the windowing system or wxWidgets, depending on platform. size (wx.Size) – The window size. The value DefaultSize indicates a default size, chosen by either the windowing system or wxWidgets, depending on platform. style (long) – The window style. See wx.Frame class description. name (string) – 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.

Note

 

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

Centre(self, direction=BOTH)

Centres the frame on the display.

Parameters:	direction (int) – The parameter may be wx.HORIZONTAL, wx.VERTICAL or wx.BOTH.

---

Create(self, parent, id=ID_ANY, title="", pos=DefaultPosition, size=DefaultSize, style=DEFAULT_FRAME_STYLE, name=FrameNameStr)

Used in two-step frame construction.

See wx.Frame for further details.

Parameters:	parent (wx.Window) – id (wx.WindowID) – title (string) – pos (wx.Point) – size (wx.Size) – style (long) – name (string) –
Return type:	bool

---

CreateStatusBar(self, number=1, style=STB_DEFAULT_STYLE, id=0, name=StatusBarNameStr)

Creates a status bar at the bottom of the frame.

Parameters:	number (int) – The number of fields to create. Specify a value greater than 1 to create a multi-field status bar. style (long) – The status bar style. See wx.StatusBar for a list of valid styles. id (wx.WindowID) – The status bar window identifier. If -1, an identifier will be chosen by wxWidgets. name (string) – The status bar window name.
Return type:	wx.StatusBar
Returns:	A pointer to the status bar if it was created successfully, None otherwise.

Note

 

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.

CreateToolBar(self, style=TB_DEFAULT_STYLE, id=ID_ANY, name=ToolBarNameStr)

Creates a toolbar at the top or left of the frame.

Parameters:	style (long) – The toolbar style. See wx.ToolBar for a list of valid styles. id (wx.WindowID) – The toolbar window identifier. If -1, an identifier will be chosen by wxWidgets. name (string) – The toolbar window name.
Return type:	wx.ToolBar
Returns:	A pointer to the toolbar if it was created successfully, None otherwise.

Note

 

By default, the toolbar is an instance of wx.ToolBar. To use a different class, override OnCreateToolBar . When a toolbar has been created with this function, or made known to the frame withwx.Frame.SetToolBar , the frame will manage the toolbar position and adjust the return value from wx.Window.GetClientSize to reflect the available space for application windows. Under Pocket PC, you should always use this function for creating the toolbar to be managed by the frame, so that wxWidgets can use a combined menubar and toolbar. Where you manage your own toolbars, create a wx.ToolBar as usual.
