how to prevent image from disappearing?

[Bobby Marvikuan]

Hi
I have a class(very big) which draws an image using paintComponent method but when I am resizing the image disappears. Can anyone suggest me a way to prevent this? I cannot use method drawImage because it is looping through and draws each time a new square to make a crossword. So, if I would use it will draw each time a new Image is there a way to do that or no???

make a class (a very little class) - just a
frame and panel (for your drawing code).

make sure it demonstrates the same problem
then post that code.

You say your problem is with drawing an image, but the code you posted doesn't have anything related to drawing an image.

It does have a whole nunch of unused imports which just add clutter, and would have been better removed before posting here.

keep going - you're 10% there.
