Camera Operation dialog box (Figure 42) uses a slider to set the Exposure Time, RS170
Intensity Scaling and Offset.
List Boxes and List Views:
A list box displays a selection from a list. An arrow button at the end of the box causes
the list of available choices to drop down. It may be a simple list of the available
selections, such as those in Figure 44, or a more complex one such as that in Figure 43.
In Figure 43, the Look In list box displays the selected folder. Clicking on the button at
the end of the box opens a browser that allows any folder (directory) to be selected. The
contents of a list box selection may additionally be listed in a list view, as in Figure 43,
where all of the files in the Data directory are listed. Figure 44 illustrates the use of list
boxes to select the Timing Mode, Shutter Control and Edge Trigger.
There may be additional display and selection options, such as those provided by the
four icons to the right of the Look In list box as shown in Figure 43. From left to right,
the first one moves one selection higher in the directory tree, the second one creates a
new folder, the third one selects the minimum information list view, and the fourth one
the detailed list view. These four icons are common to all list views. Within the list view,
there may be right-click mouse functions as well. Right clicking in the view area but not
on a file name opens a menu that gives additional selections for the organization and
display in the list view. Right clicking on a file name opens a menu of operations that
can be performed on the selected file.
If there are more choices than can fit in the list view, scrollbar(s) appear that you can use
to move the unseen choices into view.
