TCustomGrid.ScrollBarPosition procedure
Sets the position for the specified scroll bar to the given value.
Declaration
procedure ScrollBarPosition(Which: Integer; Value: Integer)Arguments
Which | Scroll bar updated in the method. |
Value | New position for the scroll bar. |
Description
ScrollBarPosition is a method used to set position for the scroll
bar specified in
Which to the new
Value.
Which contains either SB_Horz or SB_Vert, and identifies the scroll bar affected in the method.
Value contains the new position for the scroll bar.
ScrollBarPosition uses the SetScrollInfo routine to update the scroll bar position. It allocates the TScrollInfo structure and stores Value as the scroll bar position in the structure.
ScrollBarPosition calls ScrollBarIsVisible to determine if the scroll bar in Which is visible. The visibility is used when calling SetScrollInfo.
No actions are performed in the method if the Handle has not been allocated for the grid control.
