Declaration

property OnSelectionChange: ;

Description

Not described here; this is what TCustomListBox.OnSelectionChange says of it:

Handler invoked when an item is selected in the control.

OnSelectionChange is a TSelectionChangeEvent property with the event handler signalled when an item selection on the control has been changed. OnSelectionChange is signalled (when assigned) from the DoSelectionChange method, and occurs prior to calling the Click method for the control.

The User argument indicates whether the selection change results from user interaction with the control (True), or from code or methods called at run-time (False).

Use OnClick to perform actions when the mouse is clicked on an item on the list box control.

Use ClickOnSelChange to indicate whether Click / OnClick are called when the left mouse button is released during a click action or when OnSelectionChanged is performed for the control.
