Minimum window size



I have a JFrame with no LayoutManager (null is specified) and have drawn sever small custom JComponents in it, one above the other. The maximum width of the components is determined and I've tried to set the window to that size plus a small buffer on the sides, but the width is smaller than the minimum width permitted for a JFrame, so the width actually gets set to the apparent minimum of 128 pixels. I'm fine with that, but would like to know what the minimum width is before I display (show()) the JFrame so that it doesn't have to get resized after being displayed. JFrame.getMinimumSize() returns the preferred size of 720. I'm hesitant to assume that it will always be 128 pixels as I suspect this could be platform-dependent. If I just let it draw at the minimum size, then I have to determine the placement of the components within the window and draw them after the JFrame is displayed - maybe I'll just have to resort to this, but I'd rather: know the minimum size in advance, do the drawing, and then display the JFrame.

How can I find the the minimum JFrame width without first displaying a JFrame?
