The following controls are available:
| Package root | Specifies a currently open project to contain the class code and other project code. Click Browse if you want to select a project other than the current one (the default value). |
| Package | Optionally specifies a package name, corresponding to a sub-folder of the package root, to contain the class file. Click Browse or enter the folder path by typing. A period (.) must separate each subfolder from its parent folder in the path name. |
| User Control name | (Required) Specifies the name of the class. The name must begin with a letter; spaces and most non-alphanumeric characters are not allowed. The .cls extension will be appended automatically. |
| Final | If checked, specifies that inheritance from this class is disallowed. A FINAL option is included in the generated ABL code.A final class cannot be abstract. |
| Abstract | If checked, specifies that the class is abstract and cannot be instantiated. An abstract class is designed to serve as a super class from which other classes inherit and implement members. Therefore, an abstract class cannot be final. |
| Widget pool | If checked, specifies that a USE-WIDGET-POOL option will be included in the generated ABL code. |
| Inherits | Optionally specifies another class in the current project as a
super class from which the new class inherits state and behavior.
Click Browse or enter the class path by
typing. A period (.) must separate each node from its parent folder
in the path name. Note: The super class cannot be generic. Moreover,
even though a control can inherit from an abstract super class,
the Visual Designer does not support designing such a control.
To design a user control that inherits from an abstract parent,
you must write the code manually.
|
| Implements | Lets you optionally specify one or more interfaces in the current
project that the class implements. Click Add
and select the desired interfaces at the Interface
Selection dialog. Use the
Remove button to remove an interface from
the list after adding it. Note: The class cannot implement a generic
interface.
|
| Generate default constructor | Specifies that the class is to include a default constructor method. Because this option is required for OpenEdge GUI for .NET forms, it is automatically checked, and the control is disabled. |
| Generate destructor | Specifies that the class is to include a destructor method. Because this option is required for OpenEdge GUI for .NET forms, it is automatically checked, and the control is disabled. |
| Generate super class constructors | If checked, specifies that the class is to include all constructor methods declared in the parent class. |
| Add routine-level error handling | If checked, specifies that the ROUTINE-LEVEL ON ERROR UNDO, THROW statement will be included in the generated ABL code. |
| Throw a Not Implemented exception | If selected, specifies that "METHOD NOT IMPLEMENTED" error code will be added to stubs for members implemented via interface and stubs for inherited abstract members. |
| Return a default value | If selected, specifies that default return values will be added to stubs for members implemented via interface and stubs for inherited abstract members. |
| Description | Lets you optionally enter a description for the class. This text will appear in the file header. |
| Purpose | Lets you optionally enter an explanation of the purpose of the class. This text will appear in the file header. |
