"Iron Resizable Behavior" framework, introduction
Iron Resizable Behavior is a JavaScript library based on the Polymer framework and is used to achieve adjustable elements that can adjust the size.The library can adjust the size of the element through the interaction with the web element, and can automatically save the adjusted size information in the attributes of the element.
The following are the main advantages and uses of Iron Resizable Behavior framework.
1. Simple and easy to use: Iron Resizable Behavior provides a simple method to realize the adjustment of the element.Just apply the behavior for the element that needs to be adjusted, and specify the direction of the adjustment size to realize the drag and drag of the element.
2. Flexibility: Iron Resizable Behavior can be applied to any elements that need to be adjusted, whether it is a simple button or a complex container.Through simple configuration, the direction and range of the size can be defined to make it suitable for various application scenarios.
The following is an example of a Java code. It demonstrates how to use Iron Resizable Behavior framework to realize elements that adjust the size.
import com.vaadin.flow.component.html.Div;
import com.vaadin.flow.component.notification.Notification;
import com.vaadin.flow.component.polymertemplate.PolymerTemplate;
import com.vaadin.flow.router.Route;
import com.vaadin.flow.templatemodel.TemplateModel;
import com.vaadin.flow.component.Tag;
import com.vaadin.flow.component.dependency.JsModule;
import com.vaadin.flow.component.polymertemplate.Id;
@Route("")
@Tag("resizable-element")
@JsModule("./src/resizable-element.js")
public class ResizableElement extends PolymerTemplate<TemplateModel> {
@Id("resizableDiv")
private Div resizableDiv;
public ResizableElement() {
IronResizableBehavior.apply(resizableDiv);
resizableDiv.getElement().addEventListener("iron-resize", event -> {
Notification.show("Element resized");
});
}
}
In the above example, we created a Vaadin Flow application and used the Polymertemplate to define a Polymer -based custom component.By specifying the `@tag` annotation as" Resizable-Element ", we bind the custom component to the HTML template called" Resizable-Element ".
"Resizable-Element" in the Polymer template uses Iron Resizable Behavior.In the Java code, we will bind the div with the java field `Resizablediv` with the DIV element with the`@ID` annotation.Then, we applied Iron Resizable Behavior to allow the DIV element to adjust the size.
By adding the listener of the `Iron-Resize` incident, we can get notified in the element adjustment in the size and display a notification in this example.
Through Iron Resizable Behavior framework, we can easily implement the element that can adjust the size.Whether it is to create a customized UI component or add element to adjust the size function in the existing applications, Iron Resizable Behavior provides us with a convenient and flexible solution.
