That is, they - can be switched on (checked) or off (unchecked). The classes - differ in how the choices for the user are restricted. Radio - buttons define a "one of many" choice, whereas checkboxes provide - "many of many" choices. - - A TQButtonGroup can be used to group check buttons visually. - - Whenever a checkbox is checked or cleared it emits the signal - toggled(). Connect to this signal if you want to trigger an action - each time the checkbox changes state. You can use isChecked() to - query whether or not a checkbox is checked. - - \warning The toggled() signal can not be trusted for tristate - checkboxes. - - In addition to the usual checked and unchecked states, TQCheckBox - optionally provides a third state to indicate "no change". This - is useful whenever you need to give the user the option of neither - checking nor unchecking a checkbox. If you need this third state, - enable it with setTristate() and use state() to query the current - toggle state. When a tristate checkbox changes state, it emits the - stateChanged() signal. - - Just like TQPushButton, a checkbox can display text or a pixmap. - The text can be set in the constructor or with setText(); the - pixmap is set with setPixmap(). - - \important text(), setText(), text(), pixmap(), setPixmap(), - accel(), setAccel(), isToggleButton(), setDown(), isDown(), - isOn(), state(), autoRepeat(), isExclusiveToggle(), group(), - setAutoRepeat(), toggle(), pressed(), released(), clicked(), - toggled(), state() stateChanged() - - <img src=qchkbox-m.png> <img src=qchkbox-w.png> - - \sa TQButton TQRadioButton - \link guibooks.html#fowler Fowler: Check Box \endlink -*/ - -/*! - \property TQCheckBox::checked - \brief whether the checkbox is checked - - The default is unchecked, i.e. FALSE. -*/ - -/*! - \property TQCheckBox::autoMask - \brief whether the checkbox is automatically masked - - \sa TQWidget::setAutoMask() -*/ - -/*! - \property TQCheckBox::tristate - \brief whether the checkbox is a tri-state checkbox - - The default is two-state, i.e. tri-state is FALSE. -*/ - -/*! - Constructs a checkbox with no text. - - The \a parent and \a name arguments are sent to the TQWidget - constructor. -*/ - -TQCheckBox::TQCheckBox( TQWidget *parent, const char *name ) - : TQButton( parent, name, TQt::WNoAutoErase | TQt::WMouseNoMask ) -{ - setToggleButton( TRUE ); - tqsetSizePolicy( TQSizePolicy( TQSizePolicy::Minimum, TQSizePolicy::Fixed ) ); -} - -/*! - Constructs a checkbox with text \a text. - - The \a parent and \a name arguments are sent to the TQWidget - constructor. -*/ - -TQCheckBox::TQCheckBox( const TQString &text, TQWidget *parent, const char *name ) - : TQButton( parent, name, TQt::WNoAutoErase | TQt::WMouseNoMask ) -{ - setText( text ); - setToggleButton( TRUE ); - tqsetSizePolicy( TQSizePolicy( TQSizePolicy::Minimum, TQSizePolicy::Fixed ) ); -} - -/*! - Sets the checkbox to the "no change" state. - - \sa setTristate() -*/ -void TQCheckBox::setNoChange() -{ - setTristate(TRUE); - setState( NoChange ); -} - -void TQCheckBox::setTristate(bool y) -{ - setToggleType( y ?
