Is it possible to autosize the jdiagram document to the size of the flowchart? I know there is a FlowChart.setAutoSizeDoc(AutoSize.AllDirections), but it doesn't shrink back once an object has been dragged. I don't mind if there isn't a feature to automatically shrink back to the correct size when dragging, but I am having trouble with a fit doc to chart button i'm trying to make. So far I have:

        Rectangle2D rect = csiFlowChart.getDocBounds();
        csiFlowChart.setAutoSizeDoc(AutoSize.None);
        BoxList oBoxes = csiFlowChart.getBoxes();
        double dRight = 0.0;
        double dBottom = 0.0;
        for (Box oBox : oBoxes) {
            if (oBox.getBounds().getX() + oBox.getBounds().getWidth() > dRight) {
                dRight = oBox.getBounds().getX() + oBox.getBounds().getWidth();
            }
            if (oBox.getBounds().getY() + oBox.getBounds().getHeight() > dBottom) {
                dBottom = oBox.getBounds().getY() + oBox.getBounds().getHeight();
            }
        }
        rect.setRect(rect.getX(), rect.getY(), dRight + 5, dBottom + 5);
        csiFlowChart.setDocBounds(rect);
        csiFlowChart.setAutoScroll(true);
        csiFlowChart.setAutoSizeDoc(AutoSize.AllDirections); 

The above seems to shrink the document to half the size of the chart for some reason.

The reason I am asking is that sometimes mistakenly, a box is dragged well outside the area of the flowchart, and with no way of shrinking the document back down, it remains huge leading to scrollbars being constantly visible with nothing off-screen.

Ah, thats where I was going wrong then. I should have added the positive X and Y rect values to the right and bottom (width and height basically) to get it working. The start X and Y positions of the rect were something like -36.0f, -55.0f, so to get the correct width and height that would make sense.

Anyway, no need now with the resizeDocToItems() functions. Thanks
