See \helpref{wxConfig overview}{wxconfigoverview} for the descriptions of all
features of this class.
+\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
languge that would work as a wrapper for wxWindows or programs where
forms or similar datagrams can be created by the uses.
+\subsection{Exec sample}\label{sampleexec}
+
+The exec sample demonstrates the \helpref{wxExecute}{wxexecute} and
+\helpref{wxShell}{wxshell} functions. Both of them are used to execute the
+external programs and the sample shows how to do this synchronously (waiting
+until the program terminates) or asynchronously (notification will come later).
+
\subsection{Scroll subwindow sample}\label{samplescrollsub}
This sample demonstrates the use of the \helpref{wxScrolledWindow}{wxscrolledwindow}
going on (of course, this only works in debug builds) and may be helpful to see
the sequence of steps of data transfer.
-Finally, the last part is used for two things: you can drag text from it to
-either one of the listboxes (only one will accept it) or another application
-and, also, bitmap pasted from clipboard will be shown there.
+Finally, the last part is used for dragging text from it to either one of the
+listboxes (only one will accept it) or another application. The last
+functionality available from the main frame is to paste a bitmap from the
+clipboard (or, in the case of Windows version, also a metafile) - it will be
+shown in a new frame.
So far, everything we mentioned was implemented with minimal amount of code
using standard wxWindows classes. The more advanced features are demonstrated
paste it or drag and drop (between one and the same or different shapes) from
one sample instance to another (or the same). However, chances are that no
other program supports this format and so shapes can also be rendered as
-bitmaps which allows them to be pasted/dropped in many other applications.
+bitmaps which allows them to be pasted/dropped in many other applications
+(and, under Windows, also as metafiles which are supported by most of Windows
+programs as well - try Write/Wordpad, for example).
Take a look at DnDShapeDataObject class to see how you may use
\helpref{wxDataObject}{wxdataobject} to achieve this.

\subsection{HTML samples}\label{samplehtml}
Eight HTML samples (you can find them in directory {\tt samples/html})
class. See also \helpref{wxNotebookSizer}{wxnotebooksizer} and
\helpref{wxSizer}{wxsizer}.
+\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
projects / wxWidgets.git / blobdiff
