h1(#wxtoplevelwindow). Wx::TopLevelWindow
TopLevelWindow is a common base class for "Dialog":dialog.html and
"Frame":frame.html. It is an abstract base class meaning that you never
work with objects of this class directly, but all of its methods are also
applicable for the two classes above.
h2. Derived from
"Window":window.html
"EvtHandler":evthandler.html
"Object":object.html

h3(#wxtoplevelenableclosebutton). TopLevelWindow#enable_close_button
Boolean *enable_close_button*(%(arg-type)Boolean% enable = true)
Enables or disables the Close button (most often in the right
upper corner of a dialog) and the Close entry of the system
menu (most often in the left upper corner of the dialog).
Currently only implemented for MSW and GTK. Returns
true if operation was successful. This may be wrong on
X11 (including GTK+) where the window manager may not support
this operation and there is no way to find out.
h3(#TopLevelWindow_getdefaultitem). TopLevelWindow#get_default_item
"Window":window.html *get_default_item*()
Returns a pointer to the button which is the default for this window, or .
The default button is the one activated by pressing the Enter key.
h3(#TopLevelWindow_geticon). TopLevelWindow#get_icon

Returns the standard icon of the window. The icon will be invalid if it hadn't
been previously set by "set_icon":#TopLevelWindow_seticon.
h4. See also
"get_icons":#TopLevelWindow_geticons
h3(#TopLevelWindow_geticons). TopLevelWindow#get_icons
"IconBundle":iconbundle.html *get_icons*()
Returns all icons associated with the window, there will be none of them if
neither "set_icon":#TopLevelWindow_seticon nor
"set_icons":#TopLevelWindow_seticons had been called before.
Use "get_icon":#TopLevelWindow_geticon to get the main icon of the
window.

window accordingly. Override this if you want to avoid resizing or do additional
operations.
h3(#TopLevelWindow_isactive). TopLevelWindow#is_active
Boolean *is_active*()
Returns if this window is currently active, i.e. if the user is currently
working with it.
h3(#TopLevelWindow_isalwaysmaximized). TopLevelWindow#is_always_maximized
Boolean *is_always_maximized*()
Returns if this window is expected to be always maximized, either due to platform policy
or due to local policy regarding particular class.

h3(#TopLevelWindow_isusingnativedecorations). TopLevelWindow#is_using_native_decorations
Boolean *is_using_native_decorations*()
This method is specific to Universal port
Returns if this window is using native decorations, if we draw
them ourselves.

Maximizes or restores the window.
h4. Parameters
* _maximize_ If , maximizes the window, otherwise it restores it.
h4. See also
"TopLevelWindow#iconize":toplevelwindow.html#TopLevelWindow_iconize
h3(#TopLevelWindow_requestuserattention). TopLevelWindow#request_user_attention
*request_user_attention*(%(arg-type)Integer% flags = USER_ATTENTION_INFO)
Use a system-dependent way to attract users attention to the window when it is
in background.
flags may have the value of either @USER_ATTENTION_INFO@
(default) or @USER_ATTENTION_ERROR@ which results in a more drastic
action. When in doubt, use the default value.
Note that this function should normally be only used when the application is
not already in foreground.
This function is currently implemented for Win32 where it flashes the
window icon in the taskbar, and for GTK with task bars supporting it.
h3(#TopLevelWindow_setdefaultitem). TopLevelWindow#set_default_item
*set_default_item*(%(arg-type)"Window":window.html% win)
Changes the default item for the panel, usually win is a button.
h4. See also
"get_default_item":#TopLevelWindow_getdefaultitem
h3(#TopLevelWindow_seticon). TopLevelWindow#set_icon
*set_icon*(%(arg-type)"Icon":icon.html% icon)
Sets the icon for this window.
h4. Parameters
* _icon_ The icon to associate with this window.
h4. Remarks
The window 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.
See also "Icon":icon.html.
h3(#TopLevelWindow_seticons). TopLevelWindow#set_icons
*set_icons*(%(arg-type)"IconBundle":iconbundle.html% icons)
Sets several icons of different sizes for this window: this allows to use
different icons for different situations (e.g. task switching bar, taskbar,
window title bar) instead of scaling, with possibly bad looking results, the
only icon set by "set_icon":#TopLevelWindow_seticon.
h4. Parameters
* _icons_ The icons to associate with this window.
h4. See also
"IconBundle":iconbundle.html.
h3(#TopLevelWindow_setleftmenu). TopLevelWindow#set_left_menu
*set_left_menu*(%(arg-type)Integer% id = ID_ANY, %(arg-type)String% label = '',

Unavailable on full keyboard machines.
h4. Parameters
* _id_ Identifier for this button.
* _label_ Text to be displayed on the screen area dedicated to this hardware button.
* _subMenu_ The menu to be opened after pressing this hardware button.

"TopLevelWindow#set_right_menu":toplevelwindow.html#TopLevelWindow_setrightmenu.
h3(#TopLevelWindow_setmaxsize). TopLevelWindow#set_max_size
*set_max_size*(%(arg-type)"Size":size.html% size)
A simpler interface for setting the size hints than
"set_size_hints":#TopLevelWindow_setsizehints.
h3(#TopLevelWindow_setminsize). TopLevelWindow#set_min_size
*set_min_size*(%(arg-type)"Size":size.html% size)
A simpler interface for setting the size hints than
"set_size_hints":#TopLevelWindow_setsizehints.
h3(#TopLevelWindow_setsizehints). TopLevelWindow#set_size_hints
*set_size_hints*(%(arg-type)Integer% minW, %(arg-type)Integer% minH, %(arg-type)Integer% maxW=-1,
%(arg-type)Integer% maxH=-1,
%(arg-type)Integer% incW=-1,
%(arg-type)Integer% incH=-1)
*set_size_hints*(%(arg-type)"Size":size.html% minSize, %(arg-type)"Size":size.html% maxSize=DefaultSize,
%(arg-type)"Size":size.html% incSize=DefaultSize)
Allows specification of minimum and maximum window sizes, and window size increments.
If a pair of values is not set (or set to -1), the default values will be used.
* _incW_ Specifies the increment for sizing the width (Motif/Xt only).
* _incH_ Specifies the increment for sizing the height (Motif/Xt only).
* _incSize_ Increment size (Motif/Xt only).
h4. Remarks
If this function is called, the user will not be able to size the window outside
the given bounds. The resizing increments are only significant under Motif or Xt.
h3(#TopLevelWindow_setrightmenu). TopLevelWindow#set_right_menu
*set_right_menu*(%(arg-type)Integer% id = ID_ANY, %(arg-type)String% label = '',
%(arg-type)"Menu":menu.html% subMenu = nil)
Sets action or menu activated by pressing right hardware button on the smart phones.
Unavailable on full keyboard machines.
h4. Parameters
* _id_ Identifier for this button.

h3(#TopLevelWindow_setshape). TopLevelWindow#set_shape
Boolean *set_shape*(%(arg-type)"Region":region.html% region)
If the platform supports it, sets the shape of the window to that
depicted by _region_. The system will not display or
respond to any mouse event for the pixels that lie outside of the
region. To reset the window to the normal rectangular shape simply
call _SetShape_ again with an empty region. Returns true if the
operation is successful.
h3(#TopLevelWindow_settitle). TopLevelWindow#set_title
*set_title*(%(arg-type)String% title)
Sets the window title.
h4. Parameters
* _title_ The window title.
h4. See also

h3(#TopLevelWindow_settransparent). TopLevelWindow#set_transparent
Boolean *set_transparent*(%(arg-type)Integer% alpha)
If the platform supports it will set the window to be translucent
h4. Parameters
* _alpha_ Determines how opaque or transparent the window will
be, if the platform supports the opreration. A value of 0 sets the
window to be fully transparent, and a value of 255 sets the window
to be fully opaque.
Returns if the transparency was successfully changed.
h3(#TopLevelWindow_shouldpreventappexit). TopLevelWindow#should_prevent_app_exit
Boolean *should_prevent_app_exit*()
This virtual function is not meant to be called directly but can be overridden
to return (it returns by default) to allow the application to
close even if this, presumably not very important, window is still opened.
By default, the application stays alive as long as there are any open top level
windows.
h3(#TopLevelWindow_showfullscreen). TopLevelWindow#show_full_screen
Boolean *show_full_screen*(%(arg-type)Boolean% show, %(arg-type)Integer% style = FULLSCREEN_ALL)
Depending on the value of _show_ parameter the window is either shown full
screen or restored to its normal state. _style_ is a bit list containing
some or all of the following values, which indicate what elements of the window
to hide in full-screen mode:
* FULLSCREEN_NOMENUBAR
* FULLSCREEN_NOTOOLBAR
* FULLSCREEN_NOSTATUSBAR
* FULLSCREEN_NOBORDER
* FULLSCREEN_NOCAPTION
* FULLSCREEN_ALL (all of the above)
This function has not been tested with MDI frames.
Note that showing a window full screen also actually
"show()s":window.html#Window_show if it hadn't been shown yet.

h3(#TopLevelWindow_usenativedecorations). TopLevelWindow#use_native_decorations
*use_native_decorations*(%(arg-type)Boolean% native = )
This method is specific to Universal port
Use native or custom-drawn decorations for this window only. Notice that to
have any effect this method must be called before really creating the window,
i.e. two step creation must be used:
MyFrame *frame = new MyFrame; // use default ctor
frame->UseNativeDecorations(false); // change from default "true"
frame->Create(parent, title, ...); // really create the frame
h4. See also
"use_native_decorations_by_default":#TopLevelWindow_usenativedecorationsbydefault,
"is_using_native_decorations":#TopLevelWindow_isusingnativedecorations
h3(#TopLevelWindow_usenativedecorationsbydefault). TopLevelWindow#use_native_decorations_by_default
*use_native_decorations_by_default*(%(arg-type)Boolean% native = )
This method is specific to Universal port
Top level windows in Universal port can use either system-provided window
decorations (i.e. title bar and various icons, buttons and menus in it) or draw
the decorations themselves. By default the system decorations are used if they
are available, but this method can be called with native set to to
change this for all windows created after this point.
Also note that if @WXDECOR@ environment variable is set, then custom
decorations are used by default and so it may make sense to call this method
with default argument if the application can't use custom decorations at all
for some reason.
