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: Shows the title bar, containing the window title, for this window. Note that this style is implicitly enabled by wx.MINIMIZE_BOX, wx.MAXIMIZE_BOX and wx.CLOSE_BOX on most systems as the corresponding buttons couldn’t be shown if the window had no title bar at all.

• wx.MINIMIZE: Identical to wx.ICONIZE. Windows only.

• wx.MINIMIZE_BOX: Displays a minimize box on the frame. This style implicitly enables wx.CAPTION too.

• 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. This style implicitly enables wx.CAPTION too.

• wx.CLOSE_BOX: Displays a close box on the frame. This style implicitly enables wx.CAPTION too.

• 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 doesn’t turn on wx.CAPTION under MSW and if it’s not specified, 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 non-null 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 or wx.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 macOS, frames with this style will be shown with a metallic look. This is an extra style. Note that this is deprecated after macOS 10.12.

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() -> None

Frame(parent, id=ID_ANY, title='', pos=DefaultPosition,
      size=DefaultSize, style=DEFAULT_FRAME_STYLE, name=FrameNameStr) -> None

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.

Return type:

None

---

__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, nullptr. If it is non-null, 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 window. This is not the same as the title of the window.

Return type:

None

Create

---

---

Centre(self, direction=BOTH)¶

Centres the frame on the display.

Parameters:

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

Return type:

None

---

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, nullptr 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.

See also

SetStatusText , OnCreateStatusBar , GetStatusBar

---

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, nullptr 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 with wx.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.

CreateStatusBar , OnCreateToolBar , SetToolBar , GetToolBar

---

DoGiveHelp(self, text, show)¶

Method used to show help string of the selected menu toolbar item.

This method is called by the default wxEVT_MENU_HIGHLIGHT event handler and also by wx.ToolBar to show the optional help string associated with the selected menu or toolbar item. It can be overridden if the default behaviour of showing this string in the frame status bar is not appropriate.

Parameters:

• text (string) – The help string to show, may be empty. The default implementation simply shows this string in the frame status bar (after remembering its previous text to restore it later).

• show (bool) – Whether the help should be shown or hidden. The default implementation restores the previously saved status bar text when it is False.

Return type:

None

See also

CreateStatusBar , wx.StatusBar.

---

OnCreateToolBar(self, style, id, name)¶

Virtual function called when a toolbar is requested by CreateToolBar .

Parameters:

• style (long) – The toolbar style. See wx.ToolBar for a list of valid styles.

PopStatusText(self, number=0)¶

Parameters:

number (int)

Return type:

None

Parameters:

• text (string)

• number (int)

Return type:

None

---

SetMenuBar(self, menuBar)¶

Tells the frame to show the given menu bar.

Parameters:

menuBar (wx.MenuBar) – The menu bar to associate with the frame.

Return type:

None

Note

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 nullptr). Under Windows, a size event is generated, so be sure to initialize data members properly before calling SetMenuBar . Note that on some platforms, it is not possible to call this function twice for the same frame object.

GetMenuBar , wx.MenuBar, wx.Menu.

---

SetStatusBar(self, statusBar)¶

Associates a status bar with the frame.

If statusBar is nullptr, then the status bar, if present, is detached from the frame, but not deleted.

Parameters:

statusBar (wx.StatusBar)

Return type:

None

See also

CreateStatusBar , wx.StatusBar, GetStatusBar

---

SetStatusBarPane(self, n)¶

Set the status bar pane used to display menu and toolbar help.

Using -1 disables help display.

Parameters:

n (int)

Return type:

None

---

SetStatusText(self, text, number=0)¶

Sets the status bar text and updates the status bar display.

This is a simple wrapper for wx.StatusBar.SetStatusText which doesn’t do anything if the frame has no status bar, i.e. GetStatusBar returns nullptr.

Parameters:

• text (string) – The text for the status field.

• number (int) – The status field (starting from zero).

Return type:

None

Note

Use an empty string to clear the status bar.

CreateStatusBar , wx.StatusBar

---

SetStatusWidths(self, widths)¶

Sets the widths of the fields in the status bar.

Parameters:

widths (list of integers) – Must contain an array of 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 SetStatusWidths .

Return type:

None

---

SetToolBar(self, toolBar)¶

Associates a toolbar with the frame.

Parameters:

toolBar (wx.ToolBar)

Return type:

None

---

SetWindowModality(self, modality)¶

Call this function before showing the frame to make it modal to the application ( wx.WindowMode.AppModal ) or just to the parent window ( wx.WindowMode.WindowModal ).

Parameters:

modality (WindowMode)

Return type:

None

Added in version 4.3/wxWidgets-3.3.2.

Note

Changing the frame modality after it has been shown has no effect
