在FXML訪問到非字符串對象可以說我有一個資源類像這樣:JavaFX的:從資源
public class Resources extends java.util.ListResourceBundle {
private static final Object[][] OBJECTS = new Object[][]{
{"FOO", "foo"},
{"BAR", 123d}
}
@Override
protected Object[][] getContents() {
return OBJECTS;
}
}
在我的應用I類加載fxml
這樣的:
Resources resources = new Resources();
FXMLLoader loader = new FXMLLoader(getClass().getResource("/foo.fxml"), resources);
Parent root = loader.load();
在我foo.fxml
我想用我的兩個字符串和我的雙重資源價值,像這樣:
<Label text="%FOO">
<Polygon>
<points>
<Double fx:value="0"/>
<Double fx:value="0"/>
<Double fx:value="%BAR"/>
<Double fx:value="0"/>
</points>
</Polygon>
第一行的作品完美,但fx:value="%BAR"
行創建例外如下:
javafx.fxml.LoadException:

所以我的問題是:如何使用資源比FXML String
對象之外?
編輯:仍然有這個問題。我甚至在我的Resource類中嘗試了{"BAR", new Double(123)}
。出現同樣的錯誤,這是真實有道理的,因爲這不是邏輯上修復異常的東西。我想了很多,我很迷茫,因爲我真的想要這樣做,不知道該怎麼做。謝謝你的幫助!
