Why is the currentStyle attribute important in web development?

Could you please explain the specific purpose of currentStyle in the context of CQ5?

Below is an example line of code:

int absParent = currentStyle.get("absParent", 3);

I am curious to know how currentStyle functions in this scenario.

Answer №1

When working with the currentStyle, you are accessing an instance of the Style class which contains properties that represent the design aspect of a cell.

Any changes made to the properties of a component in design mode will be saved under either

/etc/designs/<<your project design>>
(if the page or its parent has a cq:design property) or /etc/designs/default (the default design). This is different from properties edited in a normal dialog, where values are stored on the same page.

Therefore, using currentStyle.get() is similar to using properties.get() as it extends ValueMap, but it retrieves values stored in the design rather than the content itself.

Although documentation on this topic may be limited, you can refer to the Designer for further understanding.

Answer №2

To put it simply, currentStyle.get() is utilized to retrieve information from design_dialog, while properties.get() is used to fetch data from a dialog.

It's important to note that the data in design_dialog is universally accessible within the template using currentStyle.get(), eliminating the need for setAttribute(). On the other hand, data in a dialog is confined to page properties and can only be accessed locally.
