\class TQPushButton ntqpushbutton.h
|
|
|
|
\brief The TQPushButton widget provides a command button.
|
|
|
|
|
|
|
|
\ingroup basic
|
|
|
|
\mainclass
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
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.
|
|
|
|
\code
|
|
|
|
TQPushButton *pb = new TQPushButton( "&Download", this );
|
|
|
|
\endcode
|
|
|
|
In this example the accelerator is \e{Alt+D}, and the label text
|
|
|
|
will be displayed as <b><u>D</u>ownload</b>.
|
|
|
|
|
|
|
|
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 setText(), setPixmap() and setIconSet().
|
|
|
|
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".
|
|
|
|
|
|
|
|
A push button emits the signal clicked() 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, pressed() and
|
|
|
|
released().
|
|
|
|
|
|
|
|
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 setAutoDefault(). 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).
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
The most important modes or states are:
|
|
|
|
\list
|
|
|
|
\i Available or not (grayed out, disabled).
|
|
|
|
\i Standard push button, toggling push button or menu button.
|
|
|
|
\i On or off (only for toggling push buttons).
|
|
|
|
\i Default or normal. The default button in a dialog can generally
|
|
|
|
be "clicked" using the Enter or Return key.
|
|
|
|
\i Auto-repeat or not.
|
|
|
|
\i Pressed down or not.
|
|
|
|
\endlist
|
|
|
|
|
|
|
|
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) \e and 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 TQFileDialog) are not command buttons,
|
|
|
|
but tool buttons. TQt provides a special class (TQToolButton) for
|
|
|
|
these buttons.
|
|
|
|
|
|
|
|
If you need toggle behavior (see setToggleButton()) or a button
|
|
|
|
that auto-repeats the activation signal when being pushed down
|
|
|
|
like the arrows in a scroll bar (see setAutoRepeat()), a command
|
|
|
|
button is probably not what you want. When in doubt, use a tool
|
|
|
|
button.
|
|
|
|
|
|
|
|
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 setPopup() to
|
|
|
|
associate a popup menu with a push button.
|
|
|
|
|
|
|
|
Other classes of buttons are option buttons (see TQRadioButton) and
|
|
|
|
check boxes (see TQCheckBox).

In TQt, the TQButton abstract base class provides most of the modes
|
|
|
|
and other API, and TQPushButton provides GUI logic. See TQButton for
|
|
|
|
more information about the API.

\property TQPushButton::autoDefault
|
|
|

\brief whether the push button is the auto default button
|

|
If this property is set to TRUE then the push button is the auto
|
|
|
|
default button in a dialog.
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
This property's default is TRUE for buttons that have a TQDialog
|
|
|
|
parent; otherwise it defaults to FALSE.
|
|
|
|
|
|
|
|
See the \l default property for details of how \l default and
|
|
|
|
auto-default interact.

\brief whether the push button is the default button

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.
|
|
|
|
|
|
|
|
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 \l autoDefault buttons the first \l autoDefault
|
|
|
|
button that is next in the tab order is pressed. If there are no
|
|
|
|
default or \l autoDefault buttons only pressing Space on a button
|
|
|
|
with focus, mouse clicking, or using an accelerator will press a
|
|
|
|
button.
|
|
|
|
|
|
|
|
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).
|
|
|
|
|
|
|
|
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.
