我有一个带有两个tableview的场景的JavaFX应用程序,第一个正常工作,第二个没有。
第二个tableview只显示它应该在5列中的2个内容,而第二列中的内容应该实际上在最后一列上。我以前曾经使用过javaFX几次,这是我第一次看到这样的东西,我修改了我的代码2到3次,寻找可能是错误或错误的东西,但我找不到它。
这是tableview显示的内容。
这是它包含的对象类的代码。
public class Producte {
private int codi;
private String nom;
private String descripcio;
private float preu;
private int codiFabricant;
public Producte(String nom, String descripcio, float preu,
int codiFabricant) {
this.nom = nom;
this.descripcio = descripcio;
this.preu = preu;
this.codiFabricant = codiFabricant;
}
public Producte(int codi, String nom, String descripcio, float preu,
int codiFabricant) {
this.codi = codi;
this.nom = nom;
this.descripcio = descripcio;
this.preu = preu;
this.codiFabricant = codiFabricant;
}
public int getCodi() {
return codi;
}
public void setCodi(int codi) {
this.codi = codi;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public String getDescripcio() {
return descripcio;
}
public void setDescripcio(String descripcio) {
this.descripcio = descripcio;
}
public float getPreu() {
return preu;
}
public void setPreu(float preu) {
this.preu = preu;
}
public int getCodiFabricant() {
return codiFabricant;
}
public void setCodiFabricant(int codiFabricant) {
this.codiFabricant = codiFabricant;
}
@Override
public String toString() {
return "Producte [codi=" + codi + ", nom=" + nom + ", descripcio="
+ descripcio + ", preu=" + preu + ", codiFabricant="
+ codiFabricant + "]";
}
}
这是加载场景的方法中的代码。 第一个tableview是dirTable,第二个(不能正常工作的是prodTable)。在此先感谢您的帮助:/

GridPane gridPane = new GridPane();

我建议您将JavaFX属性用于所有模型。您可以在here中找到示例。
PropertyValueFactory<S,T>
在T
中查找S
类型的属性,其名称与您在构造函数中输入的名称相同。
例如,在具有StringProperty字段Product
的模型类name
中,
new PropertyValueFactory<Product, String>("name")
将寻找:
nameProperty()
如果它找不到它,它会进一步查找getName()
并在返回之前将其包裹在ReadOnlyObjectWrapper
中。
来自文档,
如果不存在与此模式匹配的方法,则存在漏洞 支持尝试调用get()或is()(即 是,上面示例中的getFirstName()或isFirstName())。如果一个方法 如果匹配此模式,则此方法返回的值为 包装在ReadOnlyObjectWrapper中并返回到TableCell
您的示例中的问题是您的表列有一个cellValueFactory,表示
nomPCol.setCellValueFactory(new PropertyValueFactory<Producte, String>("Preu"));
但是您的getter方法返回的是float
而不是String
public float getPreu() {
return preu;
}

我已经发现了问题,我使用复制+粘贴来复制代码行,我忘了更改表的列上的名称。我是个白痴-__-。
抱歉浪费你的时间......
顺便问一下,有没有办法在没有问mods之类的情况下关闭一个帖子/问题?
