TColorButton.GroupIndex property

Declaration

property GroupIndex:;

Description

Not described here; this is what TCustomSpeedButton.GroupIndex says of it:

Identifies the group to which the speed button control belongs.

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.
