Analysis

Overview

Frame property locking provides the ability a property to be protected from changing. Frame property locking should be presented to the user as a checkbox in the Frame hud. When the checkbox is checked for a property, it's value will not be changeable until it's checkbox is unchecked.

Task requirements

Provide a prototype of frame property locking. Locking should be available for frame:

• content
• insets
• bounds
• border style
• background style
• shadow style

Providing locking for these is enough for this revision. In later revisions, they may be split into sub-elements (border style - border thickness, border color, etc).

Task result

The result of this task must be code.

Implementation idea

Create a value property

• contentLock
• insetsLock
• boundsLock
• borderLock
• backgroundLock
• shadowLock

at the Frame class.

How to demo

• Create a frame.
• Lock the border.
• Change border width.
• Assert that border width is the same.

Design

• Add following properties in the Frame class
  • RwProp<Boolean> contentLock() - value property - It will provide if content could be changed. If content is locked, it could not be changed.
  • RwProp<Boolean> borderLock() - value property - It will provide if border could be changed. If border is locked, it could not be changed.
  • RwProp<Boolean> backgroundLock() - value property - It will provide if background could be changed. If background is locked, it could not be changed.
  • RwProp<Boolean> shadowLock() - value property - It will provide if shadow could be changed. If shadow is locked, it could not be changed.
  • RwProp<Boolean> paddingInsetsLock() - value property - It will provide if padding could be changed. If padding is locked, it could not be changed.
  • RwProp<Boolean> marginInsetsLock() - value property - It will provide if margin could be changed. If margin is locked, it could not be changed.
