\section{\class{wxTopLevelWindow}}\label{wxtoplevelwindow}

wxTopLevelWindow is a common base class for \helpref{wxDialog}{wxdialog} and
\helpref{wxFrame}{wxframe}. 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.

\wxheading{Derived from}

\helpref{wxWindow}{wxwindow}\\
\helpref{wxEvtHandler}{wxevthandler}\\
\helpref{wxObject}{wxobject}

\wxheading{Include files}

<wx/toplevel.h>


\latexignore{\rtfignore{\wxheading{Members}}}

\membersection{wxTopLevelWindow::CanSetTransparent}\label{wxtoplevelwindowcansettransparent}

\func{virtual bool}{CanSetTransparent}{\void}

Returns \true if the platform supports making the window translucent.

\wxheading{See also}

\helpref{wxTopLevelWindow::SetTransparent}{wxtoplevelwindowsettransparent}


\membersection{wxTopLevelWindow::EnableCloseButton}\label{wxtoplevelenableclosebutton}

\func{bool}{EnableCloseButton}{\param{bool}{ 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 wxMSW and wxGTK. 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.

\membersection{wxTopLevelWindow::GetDefaultItem}\label{wxtoplevelwindowgetdefaultitem}

\constfunc{wxWindow *}{GetDefaultItem}{\void}

Returns a pointer to the button which is the default for this window, or \NULL.
The default button is the one activated by pressing the Enter key.


\membersection{wxTopLevelWindow::GetIcon}\label{wxtoplevelwindowgeticon}

\constfunc{const wxIcon\&}{GetIcon}{\void}

Returns the standard icon of the window. The icon will be invalid if it hadn't
been previously set by \helpref{SetIcon}{wxtoplevelwindowseticon}.

\wxheading{See also}

\helpref{GetIcons}{wxtoplevelwindowgeticons}


\membersection{wxTopLevelWindow::GetIcons}\label{wxtoplevelwindowgeticons}

\constfunc{const wxIconBundle\&}{GetIcons}{\void}

Returns all icons associated with the window, there will be none of them if
neither \helpref{SetIcon}{wxtoplevelwindowseticon} nor
\helpref{SetIcons}{wxtoplevelwindowseticons} had been called before.

Use \helpref{GetIcon}{wxtoplevelwindowgeticon} to get the main icon of the
window.

\wxheading{See also}

\helpref{wxIconBundle}{wxiconbundle}


\membersection{wxTopLevelWindow::GetTitle}\label{wxtoplevelwindowgettitle}

\constfunc{wxString}{GetTitle}{\void}

Gets a string containing the window title.

\wxheading{See also}

\helpref{wxTopLevelWindow::SetTitle}{wxtoplevelwindowsettitle}


\membersection{wxTopLevelWindow::HandleSettingChange}\label{wxtoplevelwindowhandlesettingchange}

\func{virtual bool}{HandleSettingChange}{\param{WXWPARAM}{ wParam}, \param{WXLPARAM}{ lParam}}

Unique to the wxWinCE port. Responds to showing/hiding SIP (soft input panel) area and resize
window accordingly. Override this if you want to avoid resizing or do additional
operations.


\membersection{wxTopLevelWindow::IsActive}\label{wxtoplevelwindowisactive}

\constfunc{bool}{IsActive}{\void}

Returns \true if this window is currently active, i.e. if the user is currently
working with it.


\membersection{wxTopLevelWindow::IsAlwaysMaximized}\label{wxtoplevelwindowisalwaysmaximized}

\constfunc{virtual bool}{IsAlwaysMaximized}{\void}

Returns \true if this window is expected to be always maximized, either due to platform policy
or due to local policy regarding particular class.


\membersection{wxTopLevelWindow::Iconize}\label{wxtoplevelwindowiconize}

\func{void}{Iconize}{\param{bool}{ iconize}}

Iconizes or restores the window.

\wxheading{Parameters}

\docparam{iconize}{If \true, iconizes the window; if \false, shows and restores it.}

\wxheading{See also}

\helpref{wxTopLevelWindow::IsIconized}{wxtoplevelwindowisiconized}, \helpref{wxTopLevelWindow::Maximize}{wxtoplevelwindowmaximize}.


\membersection{wxTopLevelWindow::IsFullScreen}\label{wxtoplevelwindowisfullscreen}

\func{bool}{IsFullScreen}{\void}

Returns \true if the window is in fullscreen mode.

\wxheading{See also}

\helpref{wxTopLevelWindow::ShowFullScreen}{wxtoplevelwindowshowfullscreen}


\membersection{wxTopLevelWindow::IsIconized}\label{wxtoplevelwindowisiconized}

\constfunc{bool}{IsIconized}{\void}

Returns \true if the window is iconized.


\membersection{wxTopLevelWindow::IsMaximized}\label{wxtoplevelwindowismaximized}

\constfunc{bool}{IsMaximized}{\void}

Returns \true if the window is maximized.


\membersection{wxTopLevelWindow::IsUsingNativeDecorations}\label{wxtoplevelwindowisusingnativedecorations}

\constfunc{bool}{IsUsingNativeDecorations}{\void}

\bftt{This method is specific to wxUniversal port}

Returns \true if this window is using native decorations, \false if we draw
them ourselves.

\wxheading{See also}

\helpref{UseNativeDecorations}{wxtoplevelwindowusenativedecorations},\\
\helpref{UseNativeDecorationsByDefault}{wxtoplevelwindowusenativedecorationsbydefault}


\membersection{wxTopLevelWindow::Maximize}\label{wxtoplevelwindowmaximize}

\func{void}{Maximize}{\param{bool }{maximize}}

Maximizes or restores the window.

\wxheading{Parameters}

\docparam{maximize}{If \true, maximizes the window, otherwise it restores it.}

\wxheading{See also}

\helpref{wxTopLevelWindow::Iconize}{wxtoplevelwindowiconize}


\membersection{wxTopLevelWindow::RequestUserAttention}\label{wxtoplevelwindowrequestuserattention}

\func{void}{RequestUserAttention}{\param{int }{flags = wxUSER\_ATTENTION\_INFO}}

Use a system-dependent way to attract users attention to the window when it is
in background.

\arg{flags} may have the value of either \texttt{wxUSER\_ATTENTION\_INFO}
(default) or \texttt{wxUSER\_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 wxGTK with task bars supporting it.


\membersection{wxTopLevelWindow::SetDefaultItem}\label{wxtoplevelwindowsetdefaultitem}

\func{void}{SetDefaultItem}{\param{wxWindow }{*win}}

Changes the default item for the panel, usually \arg{win} is a button.

\wxheading{See also}

\helpref{GetDefaultItem}{wxtoplevelwindowgetdefaultitem}


\membersection{wxTopLevelWindow::SetIcon}\label{wxtoplevelwindowseticon}

\func{void}{SetIcon}{\param{const wxIcon\& }{icon}}

Sets the icon for this window.
