Cancel button

Use a Cancel button only with windows that use an OK button. A cancel operation should allow the user to close a window without being subjected to any “side effects” of the window’s dismissal. Typically, this means that no warning dialogs should appear asking whether the user wants to save changes, nor should any requests appear that the user provide more information prior to the window closing.

In addition, observe the following guidelines when adding a Cancel button:

• Don’t use a Cancel button with windows that display an editable scrolling window. Dexterity saves changes made in an editable scrolling window to the linked table automatically, and you cannot reverse, or roll back these changes once a cancel operation occurs for the window.
• Set the Cancel button’s Hyperspace property to True. This prevents the change script for the currently focused window field from running when the user clicks the Cancel button.

Example 1: Cancel button change script

The following Cancel button script in the RM_Aging window simply closes the RM_Aging form:

close form RM_Aging;
