2.3 Tool Box Window

Sometimes it is necessary to adjust certain values while a measurement is running. Often this happens when one is trying to determine optimum parameters for an experiment. Therefore fsc2 allows to create several different kinds of graphical objects for user input during the experiment. All these elements appear in a separate window, the tool box.

Please note that fsc2 usually will not be able to do a real thorough test before the experiment is started when the tool box is used. In this case the flow of control is often controlled by user input which can not be predicted. Therefore fsc2 may have no chance to determine which parts of the EDL will be run at what time and if data to be send to devices will be correct. For these reasons it is probably better not to use a tool box when running important experiments, or only a tool box to display (but not change) relevant data.

The next figure shows all types of objects that can be created.


First there are the normal buttons. A normal button can be clicked on to and the EDL script can determine how often the button has been pressed. The second type of objects are push buttons, i.e. buttons that can be in two states, either pressed or released. The third type of objects, radio buttons, always come in groups and only exactly one of a group of radio buttons can be in the active state at any moment.

The next set of objects are sliders to adjust numerical values in a predefined range. There are two types of sliders, normal sliders and value sliders. The only difference between these is that value sliders have an additional field displaying a number that indicates the value the slider is currently set to.

Beside sliders also in- and output objects can be used to set numerical values. Input objects are boxes into which the user can enter numbers, while output objects are used to display numerical values. Both object types come in two variants, one that allows the input or display of integer values only and one for floating point numbers.

Finally, there are pop-up-menu buttons. If clicked on a menu with two or more items to select pops up and allows the user to chose one of several alternatives.
