Example 1 with BorderLayoutConstraint

use of com.github.bordertech.wcomponents.layout.BorderLayout.BorderLayoutConstraint in project wcomponents by BorderTech.

the class BorderLayoutRenderer method paintChildrenWithConstraint.

/**
 * Paints all the child components with the given constraint.
 *
 * @param children the list of potential children to paint.
 * @param renderContext the RenderContext to paint to.
 * @param constraint the target constraint.

    String containingTag = null;
    XmlStringBuilder xml = renderContext.getWriter();
    final int size = children.size();
    for (int i = 0; i < size; i++) {
        Duplet<WComponent, BorderLayoutConstraint> child = children.get(i);
        if (constraint.equals(child.getSecond())) {
            if (containingTag == null) {
                containingTag = getTag(constraint);
                xml.appendTag(containingTag);
            }

Example 2 with BorderLayoutConstraint

use of com.github.bordertech.wcomponents.layout.BorderLayout.BorderLayoutConstraint in project wcomponents by BorderTech.

the class BorderLayoutRenderer method doRender.

 * @param component the container to paint.
 * @param renderContext the RenderContext to paint to.
