如何调整/缩放复杂的JFrame

Question

I have a complex JFrame. It has a main panel in absoluteLayout, which has buttons and labels, a couple of jFreeCharts and a second(sub) panel with a specific GridLayout, which I fill with multiple labels.

Is there anyway to resize/zoom the whole thing?

pack() does not work because of the layout.

Is there a more rudimentary "ScaleTheWholeWindow" approach?

The code for my comment would look something like this. I didn't test this, this is more an idea. Easier to articulate my idea with code.

public void scaleContainer(Container c, double xFactor, double yFactor)
{
    Component[] eles = c.getComponents();
    for(int i = 0 ; i < eles.length ; i++)
    {
        eles[i].setBounds(new Rectangle(
             (int) eles[i].getX() * xFactor, 
             (int) eles[i].getY() * yFactor, 
             (int) eles[i].getWidth() * xFactor, 
             (int) eles[i].getHeight() * yFactor))
        if(eles[i] instanceof Container)
        {
            if(((Container)eles[i]).getLayout() == null) //If the container has it's own layout, let it assign it's own components
                scaleContainer((Conatiner)eles[i], xFactor, yFactor);
        }
    }
}

If you want to scale by a fixed number of pixels, and not a factor, then you need to calculate the factor. The factor would be 1 + (extraWidth / previousWidth) (and similar for height)

我不知道如何按照您的要求进行操作，但是更好的方法是将每个元素的宽度/高度设置为当前宽度/高度的百分比的函数，这样您将始终获得相同的结果布局，而不是您要求的基本布局。
