Paint Background of Hierarchical Table Node

Postby poregan » Thu Feb 27, 2014 10:15 am

In the Hierarchical Table I want to paint to the background color of the margin that is directly under the expand/collaspe node. Is this possible?

I have tired to setMarginBackground but this doesnt paint the area under the icon rather just the space under the name of the parent node.

Any suggestions?

You can call HierarchicalTable#setMarginBackground to change the color.

As mentioned I have already tried this and it will paint the area around the expand/collapse icon and will also paint the area to the left of the child component but only to the point where the expand " L " icon begins.

I want to paint the panel containing the L (expand) icon.

Currently there is no way to paint different colors for the background of the expand/collapse icon and the "L" line. You will have to write your code. The L line's background is painted in TreeLikeHierarchicalPanel. It extends HierarchicalTable and have this paintComponent. You can modify it to paint yourself.

Code: Select all
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.setColor(UIDefaultsLookup.getColor("Tree.hash"));
        if (getComponentOrientation().isLeftToRight()) {
            g.drawLine(ExpandablePanel.LEFT_MARGIN / 2, 0, ExpandablePanel.LEFT_MARGIN / 2, ExpandablePanel.LEFT_MARGIN);
            g.drawLine(ExpandablePanel.LEFT_MARGIN / 2, ExpandablePanel.LEFT_MARGIN, ExpandablePanel.LEFT_MARGIN, ExpandablePanel.LEFT_MARGIN);
        }
        else {
            g.drawLine(getWidth() - ExpandablePanel.LEFT_MARGIN / 2 - 2, 0, getWidth() - ExpandablePanel.LEFT_MARGIN / 2 - 2, ExpandablePanel.LEFT_MARGIN);
            g.drawLine(getWidth() - ExpandablePanel.LEFT_MARGIN / 2 - 2, ExpandablePanel.LEFT_MARGIN, getWidth() - ExpandablePanel.LEFT_MARGIN, ExpandablePanel.LEFT_MARGIN);
        }
    }

By calling setBackground on the TreeLikeHierarchicalPanel that I return in the TableComponentFactory.createChildComponent I was able to achieve what I was looking for.

Thanks for your help.
