GetResizeColumn returns the zero-based column number of the column being affected by the current notification.  If a split tree control is used, the return value can be -1 indicating that the splitter bar was used to resize the left and right panes or the splitter bar was double-clicked.

Comments

The GetResizeColumn function returns the column number of the column being resized.

GetResizeColumn can be used while processing a SFTTREEN_COLUMNSIZE or SFTTREEN_LBUTTONDBLCLK_COLUMNRES notification to determine whether the splitter bar or a column was affected by the current event.
