TCustomSpeedButton.AllowAllUp property
Indicates if all buttons in a group can be in an up state.
Declaration
property AllowAllUp: Boolean read FAllowAllUp write SetAllowAllUp default False;Description
AllowAllUp is a
Boolean property which indicates
whether all speed buttons with the same
GroupIndex value can be in
the "up" state. The default value for the property is
False, and means
that one of the grouped speed buttons must have its
Down property
set to
True when GroupIndex has a non-zero value.
Changing the value for the property causes a button pressed event to be sent to the Parent control (when assigned) and the Down property is toggled and updated for the new property value.
Set GroupIndex to a value other than 0 (zero) to use AllowAllUp when a mouse button or an accelerator key is handled for the control.
