command button. +<p> + +<p> 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. +<p> 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. +<pre> + TQPushButton *pb = new TQPushButton( "&Download", this ); + </pre> + +In this example the accelerator is <em>Alt+D</em>, and the label text +will be displayed as <b><u>D</u>ownload</b>. +<p> 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 <a href="ntqbutton.html#setText">setText</a>(), <a href="ntqbutton.html#setPixmap">setPixmap</a>() and <a href="#setIconSet">setIconSet</a>(). +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". +<p> A push button emits the signal <a href="ntqbutton.html#clicked">clicked</a>() 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, <a href="ntqbutton.html#pressed">pressed</a>() and +<a href="ntqbutton.html#released">released</a>(). +<p> 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 <a href="#setAutoDefault">setAutoDefault</a>(). 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). +<p> 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. +<p> The most important modes or states are: +<ul> +<li> Available or not (grayed out, disabled). +<li> Standard push button, toggling push button or menu button. +<li> On or off (only for toggling push buttons). +<li> Default or normal. The default button in a dialog can generally +be "clicked" using the Enter or Return key. +<li> Auto-repeat or not. +<li> Pressed down or not. +</ul> +<p> 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) <em>and</em> 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 <a href="tqfiledialog.html">TQFileDialog</a>) are not command buttons, +but tool buttons. TQt provides a special class (<a href="tqtoolbutton.html">TQToolButton</a>) for +these buttons. +<p> If you need toggle behavior (see <a href="#setToggleButton">setToggleButton</a>()) or a button +that auto-repeats the activation signal when being pushed down +like the arrows in a scroll bar (see <a href="ntqbutton.html#setAutoRepeat">setAutoRepeat</a>()), a command +button is probably not what you want. When in doubt, use a tool +button. +<p> 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 <a href="#setPopup">setPopup</a>() to +associate a popup menu with a push button. +<p> Other classes of buttons are option buttons (see <a href="tqradiobutton.html">TQRadioButton</a>) and +check boxes (see <a href="tqcheckbox.html">TQCheckBox</a>). +<p> <img src="tqpushbt-m.png"> <img src="tqpushbt-w.png"> +<p> In TQt, the <a href="ntqbutton.html">TQButton</a> abstract base class provides most of the modes +and other API, and TQPushButton provides GUI logic.
