TdxCustomLayoutCheckableItem Class

The base class for all check boxes and radio buttons in the layout control.

Declaration

TdxCustomLayoutCheckableItem = class(
    TdxCustomLayoutLabeledItem
)

Remarks

This class is the direct ancestor of the TdxLayoutCheckBoxItem and TdxLayoutRadioButtonItem classes that implement checkable items in the layout control.

The TdxCustomLayoutCheckableItem class extends its ancestor with the following members that allow you to:

• Assign an action to the item (Action).

• Switch the item between checked and unchecked states (Checked).

• Respond to an item’s state change (OnClick).

You do not need to create the TdxCustomLayoutCheckableItem class instances, use its descendants instead.
