Usage

From source file:org.nuclos.client.ui.resplan.header.JHeaderGrid.java

private void calculateGroupingExtents() {
    final Orientation groupOrient = orientation.opposite();
    int preferredGroupingsExtent = 0;
    for (CategoryView categoryView : groupings) {
        int preferredCategorySize = 0;
        for (HeaderCell cell : categoryView.cells) {
            JComponent renderer = setupCellRenderer(cell.levelValue, false);
            Dimension preferredSize = renderer.getPreferredSize();
            int preferredExtent = groupOrient.extentFrom(preferredSize);
            if (renderer instanceof JLabel) {
                // This is a some kind of hack for determing the preferred size of an HTML JLabel
                // using a given width or height. See also:
                // http://blog.nobel-joergensen.com/2009/01/18/changing-preferred-size-of-a-html-jlabel/
                // NOTE: This seems to work for horizontal orientations (i.e. calculating the height for a
                // given width) while for vertical orientations often the dummy value 0 is returned.
                View view = (View) renderer.getClientProperty(javax.swing.plaf.basic.BasicHTML.propertyKey);
                if (view != null) {
                    float w = (orientation == Orientation.HORIZONTAL) ? cellExtent : 0;
                    float h = (orientation == Orientation.VERTICAL) ? cellExtent : 0;
                    view.setSize(w, h);
                    float span = (int) Math.ceil(view.getPreferredSpan(groupOrient.swingConstant()));
                    preferredExtent = Math.max(preferredExtent, (int) Math.ceil(span));
                }//from   w  w w  .  j  a v a  2s . c  o m
            }
            preferredCategorySize = Math.max(preferredCategorySize, preferredExtent + 2);
        }
        categoryView.preferredSize = preferredCategorySize;
        categoryView.size = preferredCategorySize;
        preferredGroupingsExtent += preferredCategorySize + GRID_SIZE;
    }

    // Real size and preferred size may vary
    int realGroupingsExtent = groupOrient.extentFrom(getSize());
    int delta = realGroupingsExtent - preferredGroupingsExtent;
    if (delta > 0) {
        int gap = delta / groupings.length;
        for (CategoryView v : groupings) {
            v.size += gap;
        }
        int rem = delta % groupings.length;
        if (rem > 0 && groupings.length > 0) {
            groupings[groupings.length - 1].size += rem;
        }
    }
