+ It usually has thick borders and a title bar, and can optionally contain a

a frame or dialog.

+ A frame that has a status bar and toolbar, created via the CreateStatusBar() and
+ CreateToolBar() functions, manages these windows and adjusts the value returned
+ by GetClientSize() to reflect the remaining size available to application windows.
+
+ @remarks An application should normally define an wxCloseEvent handler for the
+ frame to respond to system close events, for example so that related
+ data and subwindows can be cleaned up.
+
+
+ @section wxframe_defaultevent Default event processing
+
+ wxFrame processes the following events:
+
+ @li @c 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;
+ @li @c 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.
+
@beginStyleTable
- @style{wxDEFAULT_FRAME_STYLE}:
+ @style{wxDEFAULT_FRAME_STYLE}
Defined as wxMINIMIZE_BOX | wxMAXIMIZE_BOX | wxRESIZE_BORDER |
wxSYSTEM_MENU | wxCAPTION | wxCLOSE_BOX | wxCLIP_CHILDREN.
- @style{wxICONIZE}:
+ @style{wxICONIZE}
Display the frame iconized (minimized). Windows only.
- @style{wxCAPTION}:
+ @style{wxCAPTION}
Puts a caption on the frame.
- @style{wxMINIMIZE}:
+ @style{wxMINIMIZE}
Identical to wxICONIZE. Windows only.
- @style{wxMINIMIZE_BOX}:
+ @style{wxMINIMIZE_BOX}
Displays a minimize box on the frame.
- @style{wxMAXIMIZE}:
+ @style{wxMAXIMIZE}
Displays the frame maximized. Windows only.
- @style{wxMAXIMIZE_BOX}:
+ @style{wxMAXIMIZE_BOX}
Displays a maximize box on the frame.
- @style{wxCLOSE_BOX}:
+ @style{wxCLOSE_BOX}
Displays a close box on the frame.
- @style{wxSTAY_ON_TOP}:
+ @style{wxSTAY_ON_TOP}
Stay on top of all other windows, see also wxFRAME_FLOAT_ON_PARENT.
- @style{wxSYSTEM_MENU}:
+ @style{wxSYSTEM_MENU}
Displays a system menu.
- @style{wxRESIZE_BORDER}:
+ @style{wxRESIZE_BORDER}
Displays a resizeable border around the window.
- @style{wxFRAME_TOOL_WINDOW}:
+ @style{wxFRAME_TOOL_WINDOW}
Causes a frame with a small titlebar to be created; the frame does
not appear in the taskbar under Windows or GTK+.
- @style{wxFRAME_NO_TASKBAR}:
+ @style{wxFRAME_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
wxMINIMIZE_BOX style). In wxGTK, the flag is respected only if GTK+
is at least version 2.2 and the window manager supports
- _NET_WM_STATE_SKIP_TASKBAR hint. Has no effect under other
- platforms.
- @style{wxFRAME_FLOAT_ON_PARENT}:
- The frame will always be on top of its parent (unlike
- wxSTAY_ON_TOP). A frame created with this style must have a
- non-@NULL parent.
- @style{wxFRAME_EX_CONTEXTHELP}:
+ _NET_WM_STATE_SKIP_TASKBAR hint. Has no effect under other platforms.
+ @style{wxFRAME_FLOAT_ON_PARENT}
+ The frame will always be on top of its parent (unlike wxSTAY_ON_TOP).
+ A frame created with this style must have a non-@NULL parent.
+ @style{wxFRAME_SHAPED}
+ Windows with this style are allowed to have their shape changed
+ with the SetShape() method.
+ @endStyleTable
+
+ The default frame style is for normal, resizeable frames.
+ To create a frame which can not be resized by user, you may use the following
+ combination of styles:
+
+ @code
+ wxDEFAULT_FRAME_STYLE & ~(wxRESIZE_BORDER | wxRESIZE_BOX | wxMAXIMIZE_BOX)
+ @endcode
+
+ See also the @ref overview_windowstyles.
+
+ @beginExtraStyleTable
+ @style{wxFRAME_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
wxDEFAULT_FRAME_STYLE ~ (wxMINIMIZE_BOX | wxMAXIMIZE_BOX) for the
frames having this style (the dialogs don't have a minimize or a
maximize box by default)
- @style{wxFRAME_SHAPED}:
- Windows with this style are allowed to have their shape changed
- with the SetShape method.
- @style{wxFRAME_EX_METAL}:
+ @style{wxFRAME_EX_METAL}
On Mac OS X, frames with this style will be shown with a metallic
look. This is an extra style.
