The TQPushButton widget provides a 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 = "ntqfiledialog.html" > TQFileDialog< / a > ) are not command buttons,
but tool buttons. TQt provides a special class (< a href = "ntqtoolbutton.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 = "ntqradiobutton.html" > TQRadioButton< / a > ) and
check boxes (see < a href = "ntqcheckbox.html" > TQCheckBox< / a > ).
< p > < img src = "qpushbt-m.png" > < img src = "qpushbt-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. See TQButton for
more information about the API.

< hr > < h2 > Property Documentation< / h2 >
< 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 = "autoDefault-prop" > < / a > autoDefault< / h3 >
< p > This property holds whether the push button is the auto default button.
< p > If this property is set to TRUE then the push button is the auto
default button in a dialog.
< p > 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.
< p > This property's default is TRUE for buttons that have a < a href = "ntqdialog.html" > TQDialog< / a >
parent; otherwise it defaults to FALSE.
< p > See the < a href = "#default-prop" > default< / a > property for details of how < a href = "#default-prop" > default< / a > and
auto-default interact.
< p > Set this property's value with < a href = "#setAutoDefault" > setAutoDefault< / a > () and get this property's value with < a href = "#autoDefault" > autoDefault< / a > ().
< h3 class = fn > bool < a name = "autoMask-prop" > < / a > autoMask< / h3 >
< p > This property holds whether the button is automatically masked.
< p > < p > < p > See also < a href = "tqwidget.html#autoMask-prop" > TQWidget::autoMask< / 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 = "ntqbutton.html#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 = "default-prop" > < / a > default< / h3 >
< p > This property holds whether the push button is the default button.
< p > If this property is set to TRUE then the push button will be
pressed if the user presses the Enter (or Return) key in a dialog.
< p > Regardless of focus, if the user presses Enter: If there is a
default button the default button is pressed; otherwise, if
there are one or more < a href = "#autoDefault-prop" > autoDefault< / a > buttons the first < a href = "#autoDefault-prop" > autoDefault< / a >
button that is next in the tab order is pressed. If there are no
default or < a href = "#autoDefault-prop" > autoDefault< / a > buttons only pressing Space on a button
with focus, mouse clicking, or using an accelerator will press a
button.
< p > 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).
< p > The default button behavior is provided only in dialogs. Buttons
can always be clicked from the keyboard by pressing Enter (or
Return) or the Spacebar when the button has focus.
< p > This property's default is FALSE.
< p > Set this property's value with < a href = "#setDefault" > setDefault< / a > () and get this property's value with < a href = "#isDefault" > isDefault< / a > ().
< h3 class = fn > bool < a name = "flat-prop" > < / a > flat< / h3 >
< p > This property holds whether the border is disabled.
< p > This property's default is FALSE.
< p > Set this property's value with < a href = "#setFlat" > setFlat< / a > () and get this property's value with < a href = "#isFlat" > isFlat< / a > ().
< h3 class = fn > < a href = "ntqiconset.html" > TQIconSet< / a > < a name = "iconSet-prop" > < / a > iconSet< / h3 >
< p > This property holds the icon set on the push button.
< p > This property will return 0 if the push button has no iconset.
< p > Set this property's value with < a href = "#setIconSet" > setIconSet< / a > () and get this property's value with < a href = "#iconSet" > iconSet< / a > ().
< h3 class = fn > bool < a name = "menuButton-prop" > < / a > menuButton< / h3 > < p > This property holds whether the push button has a menu button on it.
< p > < b > This property is obsolete.< / b > It is provided to keep old source working. We strongly advise against using it in new code.
< p > If this property is set to TRUE, then a down arrow is drawn on the push
button to indicate that a menu will pop up if the user clicks on the
arrow.
< p > Get this property's value with < a href = "#isMenuButton" > isMenuButton< / a > ().
< h3 class = fn > bool < a name = "on-prop" > < / a > on< / h3 >
< p > This property holds whether the push button is toggled.
< p > This property should only be set for toggle push buttons. The
default value is FALSE.
< p > < p > See also < a href = "#on-prop" > on< / a > , < a href = "ntqbutton.html#toggle" > toggle< / a > (), < a href = "ntqbutton.html#toggled" > toggled< / a > (), and < a href = "#toggleButton-prop" > toggleButton< / a > .
< p > Set this property's value with < a href = "#setOn" > setOn< / a > ().
< h3 class = fn > < a href = "ntqpixmap.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 = "ntqbitmap.html" > TQBitmap< / a > or its < a href = "ntqpixmap.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 = "ntqbutton.html#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 > ().
< h3 class = fn > < a href = "ntqstring.html" > TQString< / a > < a name = "text-prop" > < / a > text< / h3 >
< p > This property holds the text shown on the button.
< p > This property will return a < a href = "ntqstring.html#TQString-null" > TQString::null< / a > if the button has no
text. If the text has an ampersand (& ) in it, then an
accelerator is automatically created for it using the character
that follows the '& ' 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 > ().
< h3 class = fn > bool < a name = "toggleButton-prop" > < / a > toggleButton< / h3 >
< p > This property holds whether the button is a toggle button.
< p > Toggle buttons have an on/off state similar to < a href = "ntqcheckbox.html" > check boxes.< / a > A push button is initially not a toggle
button.
< p > < p > See also < a href = "#on-prop" > on< / a > , < a href = "ntqbutton.html#toggle" > toggle< / a > (), < a href = "#toggleButton-prop" > toggleButton< / a > , and < a href = "ntqbutton.html#toggled" > toggled< / a > ().
< p > Set this property's value with < a href = "#setToggleButton" > setToggleButton< / a > ().
