Arv*_*nem 3 java notifications swing listener mutation
我想知道是否有某种魔法可以用来解决IllegalStateException并允许JTextField"尝试在通知中变异",或者换句话说,如果触发了侦听器则设置自己的文本.
为了您的信息,我正在尝试编写一个自动完成函数,该函数返回12个枚举范围内最可能的匹配,以响应用户在JTextField中的输入.
这是代码示例.你必须原谅我笨拙的算法,这会扼杀枚举结果.我突出显示了通过注释产生异常的代码:
jtfElement1.addCaretListener(new CaretListener() {
@Override
public void caretUpdate(CaretEvent e) {
String s = jtfElement1.getText();
int[] attributes = new int[13];
// iterate through each enum
for (BaseEnumAttributes b: BaseEnumAttributes.values()) {
// iterate through the length of the current text in jtfElement1
for (int i = 0; i < s.length(); i++) {
if (s.length() <= b.toString().length()) {
if (b.toString().charAt(i) == s.charAt(i)) {
// increase the number of "hits" noted for that enum
attributes[b.ordinal()] = attributes[b.ordinal()] + 1;
}
}
}
}
int priorC = 0;
int rightC = 0;
// iterate through the "array" of enums to find the highest score
for (int j = 0; j < attributes.length; j++) {
if (attributes[j] > priorC) {
priorC = attributes[j];
rightC = j;
}
}
if (!s.equals("")) {
// assign to b the Enum corresponding to the "array" with highest score
BaseEnumAttributes b = BaseEnumAttributes.values()[rightC];
iController.updateInputElement1String(b.toString());
// THIS TRIGGERS EXCEPTION
jtfElement1.setText(b.toString());
}
}
});
