+
+
+The TQButton class is the abstract base class of button
+widgets, providing functionality common to buttons.
+<p>
+<p> <b>If you want to create a button use <a href="tqpushbutton.html">TQPushButton</a>.</b>
+<p> The TQButton class implements an <em>abstract</em> button, and lets
+subclasses specify how to reply to user actions and how to draw
+the button.
+<p> TQButton provides both push and toggle buttons. The <a href="tqradiobutton.html">TQRadioButton</a>
+and <a href="tqcheckbox.html">TQCheckBox</a> classes provide only toggle buttons; TQPushButton and
+<a href="tqtoolbutton.html">TQToolButton</a> provide both toggle and push buttons.
+<p> Any button can have either a text or pixmap label. <a href="#setText">setText</a>() sets
+the button to be a text button and <a href="#setPixmap">setPixmap</a>() sets it to be a
+pixmap button. The text/pixmap is manipulated as necessary to
+create the "disabled" appearance when the button is disabled.
+<p> TQButton provides most of the states used for buttons:
+<ul>
+<li> <a href="#isDown">isDown</a>() indicates whether the button is <em>pressed</em> down.
+<li> <a href="#isOn">isOn</a>() indicates whether the button is <em>on</em>.
+Only toggle buttons can be switched on and off (see below).
+<li> <a href="tqwidget.html#isEnabled">isEnabled</a>() indicates whether the button can be pressed by the
+user.
+<li> <a href="#setAutoRepeat">setAutoRepeat</a>() sets whether the button will auto-repeat
+if the user holds it down.
+<li> <a href="#setToggleButton">setToggleButton</a>() sets whether the button is a toggle
+button or not.
+</ul>
+<p> The difference between isDown() and isOn() is as follows: When the
+user clicks a toggle button to toggle it on, the button is first
+<em>pressed</em> and then released into the <em>on</em> state. When the user
+clicks it again (to toggle it off), the button moves first to the
+<em>pressed</em> state, then to the <em>off</em> state (isOn() and isDown()
+are both FALSE).
+<p> Default buttons (as used in many dialogs) are provided by
+<a href="tqpushbutton.html#setDefault">TQPushButton::setDefault</a>() and <a href="tqpushbutton.html#setAutoDefault">TQPushButton::setAutoDefault</a>().
+<p> TQButton provides five signals:
+<ol type=1>
+<li> <a href="#pressed">pressed</a>() is emitted when the button is pressed. E.g. with the mouse
+or when <a href="#animateClick">animateClick</a>() is called.
+<li> <a href="#released">released</a>() is emitted when the button is released. E.g. when the mouse
+is released or the cursor is moved outside the widget.
+<li> <a href="#clicked">clicked</a>() is emitted when the button is first pressed and then
+released when the accelerator key is typed, or when
+animateClick() is called.
+<li> <a href="#toggled">toggled</a>(bool) is emitted when the state of a toggle button changes.
+<li> <a href="#stateChanged">stateChanged</a>(int) is emitted when the state of a tristate
+toggle button changes.
+</ol>
+<p> If the button is a text button with an ampersand (&amp;) in its text,
+TQButton creates an automatic accelerator key. This code creates a
+push button labelled "Ro<u>c</u>k &amp; Roll" (where the c is
+underlined). The button gets an automatic accelerator key, Alt+C:
+<p> <pre>
+ <a href="tqpushbutton.html">TQPushButton</a> *p = new <a href="tqpushbutton.html">TQPushButton</a>( "Ro&amp;ck &amp;&amp; Roll", this );
+ </pre>
+
+<p> In this example, when the user presses Alt+C the button will call
+<a href="#animateClick">animateClick</a>().
+<p> You can also set a custom accelerator using the <a href="#setAccel">setAccel</a>()
+function. This is useful mostly for pixmap buttons because they
+have no automatic accelerator.
+<p> <pre>
+ p-&gt;setPixmap( TQPixmap("print.png") );
+ p-&gt;setAccel( ALT+Key_F7 );
+ </pre>
+
+<p> All of the buttons provided by TQt (<a href="tqpushbutton.html">TQPushButton</a>, <a href="tqtoolbutton.html">TQToolButton</a>,
+<a href="tqcheckbox.html">TQCheckBox</a> and <a href="tqradiobutton.html">TQRadioButton</a>) can display both text and
+pixmaps.
+<p> To subclass TQButton, you must reimplement at least <a href="#drawButton">drawButton</a>()
+(to draw the button's outline) and <a href="#drawButtonLabel">drawButtonLabel</a>() (to draw its
+text or pixmap). It is generally advisable to reimplement
+<a href="tqwidget.html#sizeHint">sizeHint</a>() as well, and sometimes <a href="#hitButton">hitButton</a>() (to determine
+whether a button press is within the button).
+<p> To reduce flickering, <a href="#paintEvent">TQButton::paintEvent</a>() sets up a pixmap that
+the drawButton() function draws in. You should not reimplement
+<a href="#paintEvent">paintEvent</a>() for a subclass of TQButton unless you want to take
+over all drawing.
+<p> <p>See also <a href="tqbuttongroup.html">TQButtonGroup</a> and <a href="abstractwidgets.html">Abstract Widget Classes</a>.

+<hr><h2>Member Type Documentation</h2>
+<h3 class=fn><a name="ToggleState-enum"></a>TQButton::ToggleState</h3>
+
+<p> This enum defines the state of a toggle button.
+<ul>
+<li><tt>TQButton::Off</tt> - the button is in the "off" state
+<li><tt>TQButton::NoChange</tt> - the button is in the default/unchanged state
+<li><tt>TQButton::On</tt> - the button is in the "on" state
+</ul>
+<h3 class=fn><a name="ToggleType-enum"></a>TQButton::ToggleType</h3>
+
+<p> This enum type defines what a button can do in response to a
+mouse/keyboard press:
+<ul>
+<li><tt>TQButton::SingleShot</tt> - pressing the button causes an action, then the
+button returns to the unpressed state.
+<li><tt>TQButton::Toggle</tt> - pressing the button toggles it between an <a href="#ToggleState-enum">On</a> and
+an <a href="#ToggleState-enum">Off</a> state.
+<li><tt>TQButton::Tristate</tt> - pressing the button cycles between the three
+states <a href="#ToggleState-enum">On</a>, <a href="#ToggleState-enum">Off</a> and <a href="#ToggleState-enum">NoChange</a>
+</ul>
+<hr><h2>Member Function Documentation</h2>

+</h3>
+Constructs a standard button called <em>name</em> with parent <em>parent</em>,
+using the widget flags <em>f</em>.
+<p> If <em>parent</em> is a <a href="tqbuttongroup.html">TQButtonGroup</a>, this constructor calls
+<a href="tqbuttongroup.html#insert">TQButtonGroup::insert</a>().
+
+<h3 class=fn><a name="~TQButton"></a>TQButton::~TQButton ()
+</h3>
+Destroys the button.
+
+<h3 class=fn><a href="ntqkeysequence.html">TQKeySequence</a> <a name="accel"></a>TQButton::accel () const
+</h3><p>Returns the accelerator associated with the button.
+See the <a href="tqbutton.html#accel-prop">"accel"</a> property for details.
+<h3 class=fn>void <a name="animateClick"></a>TQButton::animateClick ()<tt> [slot]</tt>
+</h3>
+Performs an animated click: the button is pressed and released a
+short while later.
+<p> The <a href="#pressed">pressed</a>(), <a href="#released">released</a>(), <a href="#clicked">clicked</a>(), <a href="#toggled">toggled</a>(), and
+<a href="#stateChanged">stateChanged</a>() signals are emitted as appropriate.
+<p> This function does nothing if the button is <a href="tqwidget.html#setEnabled">disabled.</a>
+<p> <p>See also <a href="#accel-prop">accel</a>.
+
+<h3 class=fn>bool <a name="autoRepeat"></a>TQButton::autoRepeat () const

+
+<p> This signal is emitted when the button is activated (i.e. first
+pressed down and then released when the mouse cursor is inside the
+button), when the accelerator key is typed or when <a href="#animateClick">animateClick</a>()
+is called. This signal is <em>not</em> emitted if you call <a href="#setDown">setDown</a>().
+<p> The <a href="tqbuttongroup.html#clicked">TQButtonGroup::clicked</a>() signal does the same job, if you want
+to connect several buttons to the same slot.
+<p> <b>Warning:</b> Don't launch a model dialog in response to this signal
+for a button that has <a href="#autoRepeat-prop">autoRepeat</a> turned on.

+<h3 class=fn><a href="ntqkeysequence.html">TQKeySequence</a> <a name="accel-prop"></a>accel</h3>
+<p>This property holds the accelerator associated with the button.
+<p>This property is 0 if there is no accelerator set. If you set this
+property to 0 then any current accelerator is removed.
+
+<p>Set this property's value with <a href="#setAccel">setAccel</a>() and get this property's value with <a href="#accel">accel</a>().
+<h3 class=fn>bool <a name="autoRepeat-prop"></a>autoRepeat</h3>
+<p>This property holds whether autoRepeat is enabled.
+<p>If autoRepeat is enabled then the <a href="#clicked">clicked</a>() signal is emitted at
+regular intervals if the button is down. This property has no
+effect on toggle buttons. autoRepeat is off by default.
+
+<p>Set this property's value with <a href="#setAutoRepeat">setAutoRepeat</a>() and get this property's value with <a href="#autoRepeat">autoRepeat</a>().
+<h3 class=fn>bool <a name="down-prop"></a>down</h3>
+<p>This property holds whether the button is pressed.
+<p>If this property is TRUE, the button is pressed down. The signals
+<a href="#pressed">pressed</a>() and <a href="#clicked">clicked</a>() are not emitted if you set this property
+to TRUE. The default is FALSE.
+
+<p>Set this property's value with <a href="#setDown">setDown</a>() and get this property's value with <a href="#isDown">isDown</a>().
+<h3 class=fn>bool <a name="exclusiveToggle-prop"></a>exclusiveToggle</h3>
+<p>This property holds whether the button is an exclusive toggle.
+<p>If this property is TRUE and the button is in a <a href="tqbuttongroup.html">TQButtonGroup</a>, the
+button can only be toggled off by another one being toggled on.
+The default is FALSE.
+
+<p>Get this property's value with <a href="#isExclusiveToggle">isExclusiveToggle</a>().
+<h3 class=fn>bool <a name="on-prop"></a>on</h3>
+<p>This property holds whether the button is toggled.

+<h3 class=fn><a href="tqpixmap.html">TQPixmap</a> <a name="pixmap-prop"></a>pixmap</h3>
+<p>This property holds the pixmap shown on the button.
+<p>If the pixmap is monochrome (i.e. it is a <a href="tqbitmap.html">TQBitmap</a> or its <a href="tqpixmap.html#depth">depth</a> is 1) and it does not have a mask,
+this property will set the pixmap to be its own mask. The purpose
+of this is to draw transparent bitmaps which are important for
+toggle buttons, for example.
+<p> <a href="#pixmap">pixmap</a>() returns 0 if no pixmap was set.
+
+<p>Set this property's value with <a href="#setPixmap">setPixmap</a>() and get this property's value with <a href="#pixmap">pixmap</a>().

+accelerator is automatically created for it using the character
+that follows the '&amp;' as the accelerator key. Any previous
+accelerator will be overwritten, or cleared if no accelerator is
+defined by the text.
+<p> There is no default text.
+
+<p>Set this property's value with <a href="#setText">setText</a>() and get this property's value with <a href="#text">text</a>().
