+    \class TQPushButton qpushbutton.h
+    \brief The TQPushButton widget provides a command button.
+
+    \ingroup basic
+    \mainclass
+
+    The push button, or command button, is perhaps the most commonly
+    used widget in any graphical user interface. Push (click) a button
+    to command the computer to perform some action, or to answer a
+    question. Typical buttons are OK, Apply, Cancel, Close, Yes, No
+    and Help.
+
+    A command button is rectangular and typically displays a text
+    label describing its action. An underlined character in the label
+    (signified by preceding it with an ampersand in the text)
+    indicates an accelerator key, e.g.
+    \code
+	TQPushButton *pb = new TQPushButton( "&Download", this );
+    \endcode
+    In this example the accelerator is \e{Alt+D}, and the label text
+    will be displayed as <b><u>D</u>ownload</b>.
+
+    Push buttons can display a textual label or a pixmap, and
+    optionally a small icon. These can be set using the constructors
+    and changed later using setText(), setPixmap() and setIconSet().
+    If the button is disabled the appearance of the text or pixmap and
+    iconset will be manipulated with respect to the GUI style to make
+    the button look "disabled".
+
+    A push button emits the signal clicked() when it is activated by
+    the mouse, the Spacebar or by a keyboard accelerator. Connect to
+    this signal to perform the button's action. Push buttons also
+    provide less commonly used signals, for example, pressed() and
+    released().
+
+    Command buttons in dialogs are by default auto-default buttons,
+    i.e. they become the default push button automatically when they
+    receive the keyboard input focus. A default button is a push
+    button that is activated when the user presses the Enter or Return
+    key in a dialog. You can change this with setAutoDefault(). Note
+    that auto-default buttons reserve a little extra space which is
+    necessary to draw a default-button indicator. If you do not want
+    this space around your buttons, call setAutoDefault(FALSE).
+
+    Being so central, the button widget has grown to accommodate a
+    great many variations in the past decade. The Microsoft style
+    guide now shows about ten different states of Windows push buttons
+    and the text implies that there are dozens more when all the
+    combinations of features are taken into consideration.
+
+    The most important modes or states are:
+    \list
+    \i Available or not (grayed out, disabled).
+    \i Standard push button, toggling push button or menu button.
+    \i On or off (only for toggling push buttons).
+    \i Default or normal. The default button in a dialog can generally
+       be "clicked" using the Enter or Return key.
+    \i Auto-repeat or not.
+    \i Pressed down or not.
+    \endlist
+
+    As a general rule, use a push button when the application or
+    dialog window performs an action when the user clicks on it (such
+    as Apply, Cancel, Close and Help) \e and when the widget is
+    supposed to have a wide, rectangular shape with a text label.
+    Small, typically square buttons that change the state of the
+    window rather than performing an action (such as the buttons in
+    the top-right corner of the TQFileDialog) are not command buttons,
+    but tool buttons. TQt provides a special class (TQToolButton) for
+    these buttons.
+
+    If you need toggle behavior (see setToggleButton()) or a button
+    that auto-repeats the activation signal when being pushed down
+    like the arrows in a scroll bar (see setAutoRepeat()), a command
+    button is probably not what you want. When in doubt, use a tool
+    button.
+
+    A variation of a command button is a menu button. These provide
+    not just one command, but several, since when they are clicked
+    they pop up a menu of options. Use the method setPopup() to
+    associate a popup menu with a push button.
+
+    Other classes of buttons are option buttons (see TQRadioButton) and
+    check boxes (see TQCheckBox).
+
+    <img src="qpushbt-m.png"> <img src="qpushbt-w.png">
+
+    In TQt, the TQButton abstract base class provides most of the modes
+    and other API, and TQPushButton provides GUI logic. See TQButton for
+    more information about the API.

+
+    In some GUI styles a default button is drawn with an extra frame
+    around it, up to 3 pixels or more. TQt automatically keeps this
+    space free around auto-default buttons, i.e. auto-default buttons
+    may have a slightly larger size hint.

+    In a dialog, only one push button at a time can be the default
+    button. This button is then displayed with an additional frame
+    (depending on the GUI style).
