\subsection{Controls sample}\label{samplecontrols}
The controls sample is the main test program for most simple controls used in
wxWindows. The sample tests their basic functionality, events, placement,
modification in terms of colour and font as well as the possibility to change
the controls programmatically, such as adding item to a list box etc. Apart
from that, the sample uses a \helpref{wxNotebook}{wxnotebook} and tests most
fetaures of this special control (using bitmap in the tabs, using
\helpref{wxSizers}{wxsizer} and \helpref{constraints}{wxlayoutconstraints} within
notebook pages, advanving pages programmatically and vetoing a page change
by intercepting the \helpref{wxNotebookEvent}{wxnotebookevent}.
The various controls tested are listed here:
\begin{twocollist}\itemsep=0pt
\twocolitem{\helpref{wxButton}{wxbutton}}{Push button control, displaying text}
\twocolitem{\helpref{wxBitmapButton}{wxbitmapbutton}}{Push button control, displaying a bitmap}
\twocolitem{\helpref{wxCheckBox}{wxcheckbox}}{Checkbox control}
\twocolitem{\helpref{wxChoice}{wxchoice}}{Choice control (a combobox without the editable area)}
\twocolitem{\helpref{wxComboBox}{wxcombobox}}{A choice with an editable area}
\twocolitem{\helpref{wxGauge}{wxgauge}}{A control to represent a varying quantity, such as time remaining}
\twocolitem{\helpref{wxStaticBox}{wxstaticbox}}{A static, or group box for visually grouping related controls}
\twocolitem{\helpref{wxListBox}{wxlistbox}}{A list of strings for single or multiple selection}
\twocolitem{wxSpinCtrl}{A spin ctrl with a text field and a `up-down' control}
\twocolitem{\helpref{wxSpinButton}{wxspinbutton}}{A spin or `up-down' control}
\twocolitem{\helpref{wxStaticText}{wxstatictext}}{One or more lines of non-editable text}
\twocolitem{\helpref{wxStaticBitmap}{wxstaticbitmap}}{A control to display a bitmap}
\twocolitem{\helpref{wxRadioBox}{wxradiobox}}{A group of radio buttons}
\twocolitem{\helpref{wxRadioButton}{wxradiobutton}}{A round button to be used with others in a mutually exclusive way}
\twocolitem{\helpref{wxSlider}{wxslider}}{A slider that can be dragged by the user}
\end{twocollist}
\subsection{Database sample}\label{sampledb}
The database sample is a small test program showing how to use the ODBC
classes written by Remstar Intl. These classes are documented in a separate
manual available from the wxWindows homepage. Obviously, this sample
requires a database with ODBC support to be correctly installed on your
system.
\subsection{Dialogs sample}\label{sampledialogs}
This sample shows how to use the common dialogs available from wxWindows. These

\subsection{Image sample}\label{sampleimage}
The image sample demonstrates the use of the \helpref{wxImage}{wximage} class
and shows how to download images in a variety of formats, currently PNG, GIF,
TIFF, JPEG, BMP, PNM and PCX. The top of the sample shows to rectangles, one
of which is drawn directly in the window, the other one is drawn into a
\helpref{wxBitmap}{wxbitmap}, converted to a wxImage, saved as a PNG image
and then reloaded from the PNG file again so that conversions between wxImage
and wxBitmap as well as loading and save PNG files are tested.
At the bottom of the main frame is a test for using a mono-chrome bitmap by
drawing into a \helpref{wxMemoryDC}{wxmemorydc}. The bitmap is then drawn
specifying the foreground and background colours with
\helpref{wxDC::SetTextForeground}{wxdcsettextforeground} and
\helpref{wxDC::SetTextBackground}{wxdcsettextbackground} (on the left). The
bitmap is then converted to a wxImage and the foreground colour (black) is
replaced with red using \helpref{wxImage::Replace}{wximagereplace}.
\subsection{Text sample}\label{sampletext}
This sample demonstrates four features: firstly the use and many variants of
