Declaration
property OnSectionResize:;Description
OnSectionResize is a
TCustomSectionNotifyEvent property
with the event handler signalled when one of the header Sections has been
resized by dragging the separator for the section. It is signalled (when
assigned) in the SectionResize method with arguments that identify the header
control and the header section for the event notification.
SectionResize / OnSectionResize occur when the left mouse button is released to complete a resizing operation. An application can implement and assign a handler routine using the signature in TCustomSectionNotifyEvent to perform actions related to the resize event for the selected section.
Use OnSectionSeparatorDblClick to handle a mouse double-click event on the section separator.
