	The headus GUI

The CySlice GUI on SGI IRIX systems has been built using the OSF/Motif toolkit. There's nothing particularly obscure about the interface; buttons look like buttons, and you click on them with the left mouse button to get them to do something. Those wanting to know more should have a look at the "OSF/Motif User's Guide", published by Prentice-Hall, Inc. (ISBN 0-13-640509-6).

On Windows NT, the GUI has been built using the Tcl/Tk toolkit, with Tix extensions. The final result is very close to that produced by the Motif toolkit, but in some respects is quite different from your typical Windows application. The biggest difference is in the File Selection window; make sure you read the next chapter, File Selection.

Opening and Closing Windows

Right arrows are usually a means to opening another window. Click on the right arrow to open the new window, and click on it again to close the window. In the new window will be a red left arrow, or a red Dismiss button, which you can also use to close the window.

Push Buttons

The color of buttons in CySlice follows this rough convention: blue for some general sort of action, green for some action that creates something new, and red to delete something or cancel some action.

Choices

The Choice element is similar to the standard Motif Option button in that it presents you with a range of options to choose from. Point at the choice you wish to pick with the mouse pointer, and click the left mouse button once to select it.

Text Input

Unlike the default for Motif, text input fields in CySlice automatically grab focus when the mouse pointer enters them.

In some situations, where you want the changed value to take effect immediately, you will need to finish off with an <Enter>.

Lists

Lists in CySlice behave exactly the same as the default Motif ones. However, not everyone is familiar with the full functionality of the Motif Lists, and so Figure 367 is included here.
