SftTree/DLL 7.5 - Tree Control

Right-To-Left Reading Support

When the extended style WS_EX_RIGHT is given, the tree control will support right-to-left reading where the tree hierarchy is displayed on the right hand side of the control. Columns are displayed from right to left, so column 0 is shown on the right side, with column 1 to its left, and so forth. The vertical scroll bar can be positioned along the left edge of the control by using the extended window style WS_EX_LEFTSCROLLBAR.

The extended window style WS_EX_LEFTSCROLLBAR is only supported by certain international Windows versions, such as Hebrew and Arabic Windows.

All tree control attributes and functions are fully supported when right-to-left reading support is used. In this documentation, the terms "left" and "right" should be reversed when the WS_EX_RIGHT window style is given.

If a split tree control is used, the tree control pane containing the hierarchy is displayed on the right side. Normally, without WS_EX_RIGHT, the hierarchy is shown in the left pane.

Using right-to-left reading support is transparent to the application, but column alignment should be adjusted by the application.
