Question about resizing a window

Question

hi,
i have a null-layout window which is resizable. the origin size is e.g. 500x300. my question: how can i manage it that resizing is only possible up to specific values for height and width, e.g. 300x150? in other words: i want to define the smallest possible size to which my window could be minimized.
thanks for every advice!
kind regards,
reinhold

hi and thanks for your replies!
sorry, i think that the desciption of my problem was not exact enough. here a second attemt: my frame is an input-mask with (for the time being) five buttons on the right side ("add", "edit", "clear", "update" and "close"). the first (upper) three buttons move their x-position dynamic when the frame is enlarged in width. they have a fixed y-pos. the lower two buttons move also dynamic: when the frame is enlarged in width they behave as the upper three buttons but when the frame is enlarged in height they change their y-pos dynamic to the frame's height. so they 'move away' in y-pos from the other three buttons. my first problem was, that when i reduce the frames height then the lower two buttons can be moved over the upper three buttons. i have solved this with the following componentListener:
contentPane.addComponentListener(new ComponentAdapter() {
    public void componentResized(ComponentEvent event) {
         // position of the upper 3 buttons:  x-pos dynamic to frame.width, y-pos. fixed
         addButton.setBounds(event.getComponent().getWidth()-120,15,100,20);
         editButton.setBounds(event.getComponent().getWidth()-120,45,100,20);
         deleteButton.setBounds(event.getComponent().getWidth()-120,75,100,20);
         // position of the lower 2 buttons: x-pos dynamic to frame.width, y-pos dynamic to frame.height
         updateButton.setBounds(event.getComponent().getWidth()-120,event.getComponent().getHeight()-60,100,20);
         closeButton.setBounds(event.getComponent().getWidth()-120,event.getComponent().getHeight()-30,100,20);
         // check minimal frame.height (165). if reached, fix y-pos of the lower two buttons
         // so they cannot be moved over the upper three buttons     
         if (event.getComponent().getHeight() <=165) {
             updateButton.setBounds(event.getComponent().getWidth()-120,105,100,20);
             closeButton.setBounds(event.getComponent().getWidth()-120,135,100,20);
});    that works fine, but my next (and main-) problem is, that i want to make it possible, that -if the height of 165 is reached- the BORDER of the frame could not be downsized anymore so that all 5 buttons remain allways visible. therefor i've found no solution in the forum's threads.
thanks for all tips!
