…I’m having difficulties trying to arrange JLabels and JButtons within in the JPanel. I would like to place them as I please, and not in the position they get placed, when they are added to the Panel.

What’s the best way to go about doing this? I’ve searched the net but can’t seem to find a decent solution.

Thanks.

null layout?

[TwoSpots]

Yes, null layout. Any suggestions?

[TwoSpots]

1lacca,

It turns out that it’s not a null layout – I was mistaken.

well now that you know, could you share with the rest of us what was it then?

...I must be missing something – this is a first for designing applets. I’m trying to rearrange the buttons and Labels and was hoping I could receive some pointers.

Here’s what I’ve implemented thus far:

	private static final int FRAME_WIDTH = 300, FRAME_HEIGHT = 450;

Excuse me did you say applet. If so then you don't need the main function here and other things. So that all be clear before we proceed. So is it an applet or not?

Yes, I am required to implement a single BlackJackApplet however, for now I just wanted to do a few tests and get familiar with the components...

[PennyBoki]

Well in the init method of the applet do all the declaration and adding the components, but just before the add of the components set the FlowLayout since I saw it commented in the code.

[TwoSpots]

...got’er figured out. Thanks for pointers, much appreciated.

[bernard.assaf]

Use AbsoluteLayout.
