The <a href="ntqradiobutton.html">TQRadioButton</a> +and <a href="ntqcheckbox.html">TQCheckBox</a> classes provide only toggle buttons; TQPushButton and +<a href="ntqtoolbutton.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="ntqwidget.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="ntqpushbutton.html#setDefault">TQPushButton::setDefault</a>() and <a href="ntqpushbutton.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 (&) in its text, +TQButton creates an automatic accelerator key. This code creates a +push button labelled "Ro<u>c</u>k & Roll" (where the c is +underlined). The button gets an automatic accelerator key, Alt+C: +<p> <pre> + <a href="ntqpushbutton.html">TQPushButton</a> *p = new <a href="ntqpushbutton.html">TQPushButton</a>( "Ro&ck && 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->setPixmap( TQPixmap("print.png") ); + p->setAccel( ALT+Key_F7 ); + </pre> + +<p> All of the buttons provided by TQt (<a href="ntqpushbutton.html">TQPushButton</a>, <a href="ntqtoolbutton.html">TQToolButton</a>, +<a href="ntqcheckbox.html">TQCheckBox</a> and <a href="ntqradiobutton.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="ntqwidget.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="ntqbuttongroup.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 class=fn><a name="TQButton"></a>TQButton::TQButton ( <a href="ntqwidget.html">TQWidget</a> * parent = 0, const char * name = 0, WFlags f = 0 ) +</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="ntqbuttongroup.html">TQButtonGroup</a>, this constructor calls +<a href="ntqbuttongroup.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="ntqbutton.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="ntqwidget.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 +</h3><p>Returns TRUE if autoRepeat is enabled; otherwise returns FALSE. +See the <a href="ntqbutton.html#autoRepeat-prop">"autoRepeat"</a> property for details. +<h3 class=fn>bool <a name="autoResize"></a>TQButton::autoResize () const +</h3><p>Returns TRUE if autoResize is enabled; otherwise returns FALSE. +See the <a href="ntqbutton.html#autoResize-prop">"autoResize"</a> property for details. +<h3 class=fn>void <a name="clicked"></a>TQButton::clicked ()<tt> [signal]</tt> +</h3> + +<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.
