Creating parameters

Overview

In the “MDAC options” window, you can access and define the parameters of a given MDA component. These parameters are organized into groups.

Creating a group

Groups can be created by clicking on the icon from a Java MDA component.

Steps:

1. In the explorer, select the Java MDA component for which you wish to create parameters.

2. Click on the icon and confirm by clicking on “OK”. The “Group” dialog box then appears.

3. Enter a name for your new parameter group and click on “OK” to confirm.

Creating a parameter

Parameters can be created by clicking on the icon from a parameter group belonging to a Java MDA component, by carrying out the steps below.

Steps:

1. In the explorer, select the parameter group to which you want to add a new parameter.

2. Click on the icon. The “Parameter” window then appears (as shown in Figure 178).

3. In the window, enter a name and a type for the new parameter and then click on “OK” to confirm. Possible types are as follows:

· boolean: This type of parameter will produce a tickbox.

· char: This type of parameter will produce a textfield.

· integer: This type of parameter will produce a textfield.

· real: This type of parameter will produce a textfield.

· string: This type of parameter will produce a textfield.

· ObjecteeringTypes::Directory: This type of parameter will produce a textfield with a button next to it, used to open a directory chooser.

· ObjecteeringTypes::File: This type of parameter will produce a textfield with a button next to it, used to open a file chooser.

· ObjecteeringTypes::Note: This type of parameter will produce a textfield.

· ObjecteeringTypes::SetOfDirectories: This type of parameter will produce a textfield with a button next to it, used to open a directory chooser.

· ObjecteeringTypes::SetOfFiles: This type of parameter will produce a textfield with a button next to it, used to open a directory chooser.

The result of the operation shown in Figure 178 is shown below.

After carrying out these operations and compiling the Java MDA component, the parameter appears in the “MDAC options” window (Figure 179).
