The view demonstrates the use of toggle buttons. In the context tree there are two special buttons "Set focus" and "Prioritize":

The "Set focus" button temporarily changes the root node of the tree to the node selected in the tree, so that the tree only displays the subtree below the current selection. The focus can be removed again by pressing the button once more. If the tree receives a new model from outside via a selection in the "Tree root" table, any focus that may have been set is automatically reset.

The "Prioritize" button displays a model status and can change it. In this example, the button shows whether the "float" value of a selected object of type "A" is greater than or equal to 1. If you press the button, a smaller value is set to 1 or a larger value is reset to 0.
