Class CheckBox

javafx.scene.control.CheckBox

All Implemented Interfaces:: Styleable, EventTarget, Skinnable

public class CheckBox
extends ButtonBase

A tri-state selection Control typically skinned as a box with a checkmark or tick mark when checked. A CheckBox control can be in one of three states:

checked: indeterminate == false, checked == true
unchecked: indeterminate == false, checked == false
undefined: indeterminate == true

If a CheckBox is checked, then it is also by definition defined. When checked the CheckBox is typically rendered with a "check" or "tick" mark. A CheckBox is in this state if selected is true and indeterminate is false.

A CheckBox is unchecked if selected is false and indeterminate is false.

A CheckBox is undefined if indeterminate is true, regardless of the state of selected. A typical rendering would be with a minus or dash, to indicate an undefined or indeterminate state of the CheckBox. This is convenient for constructing tri-state checkbox based trees, for example, where undefined check boxes typically mean "inherit settings from the parent".

The allowIndeterminate variable, if true, allows the user to cycle through the undefined state. If false, the CheckBox is not in the indeterminate state, and the user is allowed to change only the checked state.

Example:

 CheckBox cb = new CheckBox("a checkbox");
 cb.setSelected(true);

MnemonicParsing is enabled by default for CheckBox.

Since:: JavaFX 2.0

setAllowIndeterminate

public final void setAllowIndeterminate(boolean value)

Sets the value of the property allowIndeterminate.

Property description:: Determines whether the user toggling the CheckBox should cycle through all three states: checked, unchecked, and undefined. If true then all three states will be cycled through; if false then only checked and unchecked will be cycled.

isAllowIndeterminate

public final boolean isAllowIndeterminate()

Gets the value of the property allowIndeterminate.

fire

public void fire()

Toggles the state of the CheckBox. If allowIndeterminate is true, then each invocation of this function will advance the CheckBox through the states checked, unchecked, and undefined. If allowIndeterminate is false, then the CheckBox will only cycle through the checked and unchecked states, and forcing indeterminate to equal to false.
