Each button in a button group has a unique identifier. - The button group emits a clicked() signal with this identifier - when a button in the group is clicked. This makes a button group - particularly useful when you have several similar buttons and want - to connect all their clicked() Q_SIGNALS to a single slot. - - An \link setExclusive() exclusive\endlink button group switches - off all toggle buttons except the one that was clicked. A button - group is, by default, non-exclusive. Note that all radio buttons - that are inserted into a button group are mutually exclusive even - if the button group is non-exclusive. (See - setRadioButtonExclusive().) - - There are two ways of using a button group: - \list - \i The button group is the parent widget of a number of buttons, - i.e. the button group is the parent argument in the button - constructor. The buttons are assigned identifiers 0, 1, 2, etc., - in the order they are created. A TQButtonGroup can display a frame - and a title because it inherits TQGroupBox. - \i The button group is an invisible widget and the contained - buttons have some other parent widget. In this usage, each button - must be manually inserted, using insert(), into the button group - and given an identifier. - \endlist - - A button can be removed from the group with remove(). A pointer to - a button with a given id can be obtained using find(). The id of a - button is available using id(). A button can be set \e on with - setButton(). The number of buttons in the group is returned by - count(). - - <img src=qbttngrp-m.png> <img src=qbttngrp-w.png> - - \sa TQPushButton, TQCheckBox, TQRadioButton -*/ - -/*! - \property TQButtonGroup::exclusive - \brief whether the button group is exclusive - - If this property is TRUE, then the buttons in the group are - toggled, and to untoggle a button you must click on another button - in the group.
