Changing parameters in StarTools

An example of a levelsetter control in StarTools

The parameters in the different modules are typically controlled by one of two types of controls­;

1. A level setter, which allows the user to quickly set the value of a parameter within a certain range
2. An item selector, which allows the user to switch between different modes.

An example of a selector control in StarTools. Clicking on its center will reaveal all options as a pop-over menu.

Setting the value represented in a level setter control is accomplished by clicking on the '+' and '-' buttons to increment or decrement the value respectively. Alternatively you can click anywhere in the area between the '-" and '+' button to set a value quickly.

Switching items in the item selector is accomplished by clicking the arrows at either end of the item description. Note that the arrows may disappear as the first or last item in a set of items is reached. Alternatively the user may click on the label area of the item selector to see the full range of items which may then be selected from a pop-over menu.
