TSpeedButton.GroupIndex property
Identifies the group to which the speed button control belongs.
Declaration
property GroupIndex:;Description
GroupIndex is used with
AllowAllUp and
Down
to determine if the button state can be changed within the related group of
controls. All buttons on the Parent control with the same value in GroupIndex
are treated as a single group. The default value for the property is 0
(zero), and indicates that an explicit value has not been assigned for the
property.
Set GroupIndex to a positive non-zero value to enable AllowAllUp checking when a mouse button event or an accelerator key is handled for the control.
This description is the one of Buttons.TCustomSpeedButton.GroupIndex.
