Positioning components in the sidebar 

You can control how components you add to the sidebar in a composite application are positioned and sized by setting the following component properties:

com.ibm.rcp.shelfView.region = {MIDDLE, TOP, BOTTOM}
The region specifies the placement of the component.

com.ibm.rcp.shelfView.state = {MAXIMIZED, RESTORED}
The state specifies how the view is restored. For instance, MAXIMIZED will make the view maximized (which minimizes all other views) when the application is opened.

com.ibm.rcp.shelfView = {RIGHT, LEFT}
The view specifies whether the component displays on the right or left.

To set these properties in the Composite Application Editor:

1. Drag a component into the Right or Left Sidebar.
2. Right-click the component and choose Edit Component Properties.
3. Click the Advanced tab to view the component proprties.
4. Add or edit one of the positioning properties.
5. Click OK.
