ich habe das GridBagLayout in einer Klasse gelöst, welche Formatierungselemente variabel zur Laufzeit parst. Voraussetzung ist Java 1.4, weil ich auf regular expressions zugreife.
Internationalisiert wird auch, dass kann man natürlich weglassen.
Vielleicht hilft das ja noch jemandem. Viele Grüße

}
else if (s.equalsIgnoreCase("ipdax")) {

}

}
}
else if (s.equalsIgnoreCase("label")) {

add(new JLabel(GP.localizeStr(a), SwingConstants.RIGHT), LabelConstraints);
gbc.gridx++;
}

}
}
public void parseFormatString(JComponent c, String s) {
if (s.equalsIgnoreCase("nl")) {

} else if (s.equalsIgnoreCase("reset")) {
int gridx=gbc.gridx;
int gridy=gbc.gridy;
gbc=(GridBagConstraints) DefaultConstraints.clone();
gbc.gridx=gridx;
gbc.gridy=gridy;
}
}
}
wird dann genutzt mit
Code:
CapitalPane = new GridBagPane(GP);
CapitalPane.add(TF_Capital, "label=i18n_Amount");
CapitalPane.add(TF_Valuta, "label=i18n_Valuta");
CapitalPane.add(TF_Rate, "nl, reset, label=i18n_Rate");
CapitalPane.add(TF_RateFrom, "label=i18n_FirstOn");
CapitalPane.add(TF_RateTo,"label=i18n_LastOn");
CapitalPane.add(TF_InterestRate, "nl, label=i18n_InterestRate");
CapitalPane.add(TF_InterestCycle, "label=i18n_InterestCycle");
CapitalPane.add(TF_DayCountConvention, "label=i18n_DayCountConvention");
OKButton = new JButton(GP.localizeStr("i18n_Execute"));
CapitalPane.add(OKButton, "nl, gridx=7, fill=HORIZONTAL");
das Ergebnis des letzen Code-Schnippsels ist dann:
