Example 1 with HTMLCollection

use of elemental.html.HTMLCollection in project che by eclipse.

the class ContentAssistWidget method update.

private void update() {
    int topVisibleItem = popupBodyElement.getScrollTop() / getItemHeight();
    int topDOMItem = Math.max(0, topVisibleItem - (DOM_ITEMS_SIZE - getItemsPerPage()) / 2);
    int bottomDOMItem = Math.min(getTotalItems() - 1, topDOMItem + DOM_ITEMS_SIZE - 1);
    if (bottomDOMItem == getTotalItems() - 1) {
        topDOMItem = Math.max(0, bottomDOMItem - DOM_ITEMS_SIZE + 1);
    }
    // resize the extra top row
    setExtraRowHeight(getExtraTopRow(), topDOMItem);
    // replace the DOM items with new content based on the scroll position
    HTMLCollection nodes = listElement.getChildren();
    for (int i = 0; i <= (bottomDOMItem - topDOMItem); i++) {
        Element newNode = createProposalPopupItem(topDOMItem + i);
        listElement.replaceChild(newNode, nodes.item(i + 1));
        // check if the item is the selected
        if (newNode.getId().equals(selectedElement.getId())) {
            selectedElement = newNode;
            selectedElement.setAttribute("selected", "true");
        }
    }
    // resize the extra bottom row
    setExtraRowHeight(getExtraBottomRow(), getTotalItems() - (bottomDOMItem + 1));
    // ensure the keyboard focus is in the visible area
    if (focused) {
        getItem(topDOMItem + (bottomDOMItem - topDOMItem) / 2).focus();
    }
}

                // we may not strictly be on the same annotation instance, but it is not discernible
                asElemental().removeChild(element);
                updateIconVisibility();
                break;
