Member Function Documentation

◆ addRadioButton()

void YRadioButtonGroup::addRadioButton ( YRadioButton radioButton)
virtual

Add a RadioButton to this button group.

RadioButtons are required to call this in their constructor.

Derived classes are free to overload this, but they should call this base class function in the overloaded function.

Definition at line 81 of file YRadioButtonGroup.cc.

◆ getProperty()

YPropertyValue YRadioButtonGroup::getProperty ( const std::string &  propertyName)
virtual

Get a property.

Reimplemented from YWidget.

This method may throw exceptions, for example

  • if there is no property with that name

Reimplemented from YWidget.

Definition at line 159 of file YRadioButtonGroup.cc.

Here is the call graph for this function:

◆ propertySet()

const YPropertySet & YRadioButtonGroup::propertySet ( )
virtual

Return this class's property set.

This also initializes the property set upon the first call.

Reimplemented from YWidget.

Reimplemented from YWidget.

Definition at line 123 of file YRadioButtonGroup.cc.

Here is the call graph for this function:

◆ radioButtonsBegin()

YRadioButtonListConstIterator YRadioButtonGroup::radioButtonsBegin ( ) const
protected

Return an iterator that points to the first RadioButton of this button group.

Note that RadioButtons in this group may be direct or indirect children of the group, so don't confuse this with YWidget::widgetsBegin().

Definition at line 60 of file YRadioButtonGroup.cc.

◆ removeRadioButton()

void YRadioButtonGroup::removeRadioButton ( YRadioButton radioButton)
virtual

Remove a RadioButton from this button group.

RadioButtons are required to call this in their destructor, but only if the button group is not also in the process of being destroyed (otherwise there may be race conditions with child widgets already destroyed):

if ( ! buttonGroup()->beingDestroyed )
    buttonGroup()->removeRadioButton( this );

Definition at line 88 of file YRadioButtonGroup.cc.

◆ setProperty()

bool YRadioButtonGroup::setProperty ( const std::string &  propertyName,
const YPropertyValue val 
)
virtual

Set a property.

Reimplemented from YWidget.

This method may throw exceptions, for example

  • if there is no property with that name
  • if the expected type and the type mismatch
  • if the value is out of range

This function returns 'true' if the value was successfully set and 'false' if that value requires special handling (not in error cases: those are covered by exceptions).

Reimplemented from YWidget.

Definition at line 143 of file YRadioButtonGroup.cc.

Here is the call graph for this function:

◆ uncheckOtherButtons()

void YRadioButtonGroup::uncheckOtherButtons ( YRadioButton radioButton)

Unchecks all radio buttons except one.

This method can be used by a concrete UI (the Qt UI or the NCurses UI) in the implementation of YRadioButton::setValue().

Definition at line 95 of file YRadioButtonGroup.cc.

Here is the call graph for this function:
