[Leonidas Savvides]

I HAVE 3 JAVA FILES [J SE], one main and two panels , and I want to refer the two panels in main AND the one panel ALSO in the other panel, rather is very complecated do static methods, well did as below but BUTTONS NOT Appear only the image plays continuesly, well???
there is one /images/ folder in the files.java folder...
this line like no called: window.add( animation2 , BorderLayout.SOUTH );//??

I couldn't even read the code for all the comments :(

[Leonidas Savvides]

I modified code , do not look in comments,

this line like no called: window.add( animation2 , BorderLayout.SOUTH );//?? line27 //LogoAnimatorMain.java
>>>
LogoAnimator animation2 = new LogoAnimator(); contains a call to //LogoAnimatorMain.java
LogoAnimatorJPanel animation = new LogoAnimatorJPanel(); // LogoAnimator.java
so first called directly(no appear), and latter called indirecrtly(appear)...

window.add( animation2.animation, BorderLayout.CENTER ); // add panel to frame LogoAnimatorMain.java
window.add( animation2 , BorderLayout.SOUTH ); //LogoAnimatorMain.java

I do NOT find better way, static comes with many errors and is difficult...
