Random components on resizing frame

what do you mean by changing layout ??

I am using null layout ..

i mean adding or removing components

The problem is not when I am moving/adding but when I am resizing frame

i realise that. resizing will trigger a relayout of the frame

and if you resize the frame by increasing onli width or height, do they dissapear in the same way?

when I say resize I actually mean resizing by clicking the by default 'restore' button between minimize and close tab ..even if I just increase height or width of frame using mouse .. the effect is same ..

Shall i try to resize frame in program on pressing a button ?? I mean is this what you want me to try when you asked  "if you resize the frame by increasing onli width or height, do they dissapear in the same way?"

definitely sounds like your not adding/removing components correctly (causing the panel to be not laid out as directed). When you resize the frame the frame gets laid out so that why you see the problem then.

how the components that disappear are added to your container? by add and setBounds() or not?

sry fr late reply .. they are added using  add()

@CEHJ .. thanks a lot for responding.. but CEHJ .. I have been doing so in so many other small programs .. nothing wents wrong ..seems like I am doing something wrong here which I am not able to notice..

will go through code once again  .. else will post  it

thank you all of you experts !!

you'll get the same problem regardless of whether you use a layout manager or not (in fact it gets more complicated using a layout manager because adding a component can cause other to move)

see my earlier comments for likely cause of the problem.

thanks for response..

can you please elaborate on your previous comment which is
