object
A SftTree object.
Text
The default Scroll Tip text. The application can override the default text by assigning a new string to the Text parameter. This string is displayed as the Tool Tip instead. If Text is set to an empty string, no Tool Tip is displayed. A maximum string length of 1000 characters is supported.
ItemIndex
The zero-based index of the first item currently displayed in the tree control client area (see Items.TopIndex).
ColIndex
The zero-based column number of the first column displayed.
Comments
The ToolTipVScroll event occurs when a ScrollTip is about to be displayed.
The ToolTipVScroll event occurs when the user scrolls the tree control contents vertically by dragging the vertical scroll bar's scroll box using the mouse.
