You can edit the logic classes and their parameters with the logic
class injection editors in the Properties view. Comply with the following
instructions when using this function:
- Select a widget on the design panel and check the Properties view. Some
properties need Java™ classes injected to make the property take effect.
For example, the Text widget.
- The Initializers, BeforeValidators, AfterValidators, Format, Actions need
implement classes defined for them. So they are logic class properties.
- For each logic class property except Format, more than one class can be
added and removed by clicking the + and - buttons,
and can be reordered by clicking the Up/Down arrows.
- Specify the class for each item and add different variables and values,
the modification can be recorded in the source codes, but nothing changes
on the design panel. See the following figure.
