them as we do with any other Java class. This approach is very similar to what GUI frameworks (like Swing or SWT) do with desktop windows and their components. Wicket and the other component oriented frameworks pages can be composed (and usually are) by many components, just like AWT windows are composed by Swing/AWT components. Both frameworks promote the reuse of presentation code and GUI elements building custom called TreeModelProvider that works with the same tree model and nodes used by Swing component javax.swing.JTree. These Swing entities should be familiar to you if you have previously worked with the old

that need to be searched for an optimal value. For example, in the US presidential elections, the swing states are the important parameters because they have many counties (subspaces) whose vote share has a US presidential election would benefit from a more aggressive focus (search) on the counties in swing states (important parameters) than those in the rest of the states (unimportant parameters). ![I

Read about using constraints the Quaternion mode the channels are converted to weighted angles in the same way as the swing angles of the Swing and X/Y/Z Twist modes. ## X /Y/Z Min, Max Independently for each axis (X, Y, and Z) the constrains one local axis of the owner to always point towards Target. This constraint uses a pure Swing rotation, i.e. the shortest possible single axis rotation. In other 3D software you can find it with
