Detailed Description¶
QButtonGroup
provides an abstract container into which button widgets can be placed. It does not provide a visual representation of this container (seeQGroupBox
for a container widget), but instead manages the states of each of the buttons in the group.An
exclusive
button group switches off all checkable (toggle) buttons except the one that has been clicked. By default, a button group is exclusive. The buttons in a button group are usually checkableQPushButton
s,QCheckBox
es (normally for non-exclusive button groups), orQRadioButton
s. If you create an exclusive button group, you should ensure that one of the buttons in the group is initially checked; otherwise, the group will initially be in a state where no buttons are checked.A button can be added to the group with
addButton()
and removed withremoveButton()
. If the group is exclusive, the currently checked button is available withcheckedButton()
. If a button is clicked, thebuttonClicked()
signal is emitted; for a checkable button in an exclusive group this means that the button has been checked. The list of buttons in the group is returned bybuttons()
.In addition,
QButtonGroup
can map between integers and buttons. You can assign an integer id to a button withsetId()
, and retrieve it withid()
. The id of the currently checked button is available withcheckedId()
, and there is an overloaded signalbuttonClicked()
which emits the id of the button. The id-1
is reserved byQButtonGroup
to mean “no such button”. The purpose of the mapping mechanism is to simplify the representation of enum values in a user interface.See also
