|
|
|
|
|
|
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.

|
</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="ntqbutton.html#animateClick">animateClick</a>()
|
|
is called. This signal is <em>not</em> emitted if you call <a href="ntqbutton.html#setDown">setDown</a>().
|
|
<p> The <a href="ntqbuttongroup.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="ntqbutton.html#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="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="ntqwidget.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>().
