Widget/Checkbox
From Gui
< Widget
A Checkbox is a widget that has a state of being "checked" or "unchecked" (or "selected" or "deselected").
Checkboxes can be grouped together. Some groups only allow one box to be "checked" at a time.
NOTE: some toolkits allow for "three state" checkboxes. These checkboxes can be "checked", "unchecked", or "neither".
Properties
- id
- checked (boolean)
- group (optional)
Events
Toolkits That Differ
- Qt uses the parent widget of their radio button widgets to infer group and has a special pseudowidget (QButtonGroup) that can be used for extra control
- XUL has a special pseudowidget that is used as the group for all radio buttons to infer group
NOTE: inputs can infer group and outputs can create pseudoparents for checkboxes that have a group
