Event handler signalled when a separator between header sections on the control is double-clicked.
Declaration
property OnSectionSeparatorDblClick: TCustomSectionNotifyEvent read FOnSectionSeparatorDblClick write FOnSectionSeparatorDblClick;Description
OnSectionSeparatorDblClick is a
TCustomSectionNotifyEvent
property with the event handler signalled when the separator for a header
section has been double-clicked. It is signalled (when assigned) from the
SectionSeparatorDblClick method. It occurs when the DblClick method handles the
mouse event when resize tracking has been enabled by hovering the mouse over
the separator for the section.
An application can implement and assign a routine using the signature in TCustomSectionNotifyEvent to respond to the event notification. Arguments passed to the handler include the header control and the header section affected in the event.
Use OnSectionTrack and OnSectionResize to perform actions needed then resize tracking is activated or completed.
