RadioButton: Widget for one-out-of-many selection.
Only one RadioButton in a RadioBox (in a RadioButtonGroup) can be set to "on" at the same time. Setting any RadioButton of a RadioButtonGroup to "on" automatically sets all others in the same RadioButtonGroup to "off".
RadioButtons customarily have a distinct visual appearance from CheckBoxes:
( ) RadioButton 1 (*) RadioButton 2 ( ) RadioButton 3 [ ] CheckBox 1 [*] CheckBox 2 [*] CheckBox 3
Constructor.
Creates a new RadioButton with user-visible text 'label'. 'label' can and should contain a keyboard shortcut (designated with '&').
The caller has to take care to add this RadioButton to its RadioButtonGroup:
if ( radioButton->buttonGroup() ) radioButton->buttonGroup()->addRadioButton( radioButton );
This can't be done in the constructor because it would involve calling a virtual function, which doesn't work yet within the constructor.

Destructor: Removes the button from the radio button group.
YRadioButtonGroup * YRadioButton::buttonGroup | ( | ) |
Get a pointer to the radio button group this button belongs to.
|
protected |
Traverse the widget hierarchy upwards to find the corresponding YRadioButtonGroup, i.e. the class that controls the radio box behaviour (i.e. that makes sure that no more than one RadioButton is set to "on" at the same time).
|
virtual |
string YRadioButton::label | ( | ) | const |
Get the label (the text on the RadioButton).
|
virtual |
|
protectedvirtual |
Set the label (the text on the RadioButton).
Derived classes are free to reimplement this, but they should call this base class method at the end of the overloaded function.
|
virtual |
Set a property. Reimplemented from YWidget.
This method may throw exceptions, for example
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.
Indicate whether or not a bold font should be used.
Derived classes are free to reimplement this, but they should call this base class method at the end of the overloaded function.
Set the radio button value (on/off).
Derived classes are required to implement this.

bool YRadioButton::useBoldFont | ( | ) | const |
Returns 'true' if a bold font should be used.
Get the current on/off value: 'true' if checked, 'false' if unchecked.
Derived classes are required to implement this.
