Oracle APEX 20: Development — Question 2

You have been assigned to maintain a forms application that was designed by a developer who has left the company.
The form uses different property classes to standardize the appearance of objects in the form. For example, all buttons should be of the same width.
The CV_Tools canvas contains several buttons. The Print invoice button is not quite wide enough to display its complete label.
In forms Builder, you open the Button_PC property class and change its Width property to a higher number. All the buttons become larger except the Print invoice button, which remains its original size. What could have caused this problem?

Answer options

• A. The Print invoice button was copied from, rather than subclassed from, the Button_PC property class.
• B. The subclass information property for the Print invoice button is blank.
• C. The Width property of the Print invoice button is an inherited property.
• D. The Width property of the Button_PC property class is a variant property.
• E. The X Position of the print invoice button is a variant property.
• F. The X Position Property is not included in the Button_PC property

Correct answer: A

Explanation

The correct answer is A because if the Print invoice button was copied instead of subclassed, it would not inherit changes made to the Button_PC property class. The other options do not accurately describe the issue, as the subclass information being blank (B) would not prevent resizing, inherited properties (C) would typically update, and variant properties (D, E, F) relate to different attributes that do not affect the button's width in this context.
