2.2. Dialog boxes

A dialog box will appear for each function of the menu requiring specification of parameters. This furnishes the user with a reliable interface that is easy to use.

A. Description of parameters

The left side of the dialog box contains short descriptions of the parameters to be entered.

B. Parameters

The blanks on the right side of the dialog box are the spaces in which the user must enter the values of the required parameters. Once the parameters have been entered, they will appear each time the dialog box is opened. If they have been saved in the initialization file, they will appear the first time the dialog box is opened. If a browse button is available, clicking it will give you access to a browse box in which you can directly select a parameter. Variables can be included in the parameters by delimiting the variables with % signs. The text designating a valid parameter appears in black. A color other than black indicates an invalid parameter. In some cases, (for example, a difference image), the parameter is optional and the box can therefore be left blank.

C. Browse buttons

To choose a parameter from a browse box, click on the browse button. Browse boxes are available for a variety of parameters, including files, colors, types of points, lines and fill, fonts and data fields.

Browse buttons give you access to the following windows from which you can choose colors, styles of points, lines and background:


D. Save parameters button

If you want the defined parameters for later use in WinDisp3.5, click the save button. This operation will save the parameters in the initialization file of WinDisp3.5, and each time the file is opened they will automatically be loaded.

E. Help button

Click the help button for a description of this function and its parameters.

F. OK/Cancel

When all the parameters have been entered, click OK to execute the function, or Cancel to abort the execution.
