如何在从Javafx的ComboBox中选择项目时在TextField上显示不同的文本？ [英] How to Display a different text on a TextField when selecting an Item From a ComboBox in Javafx?
本文介绍了如何在从Javafx的ComboBox中选择项目时在TextField上显示不同的文本？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
所以我想从一个Combobox中选择一个项目，在点击选择的项目后，它应该返回一个不同的文本在javafx中的TextField。我有一个问题，这样做是我的代码
我有一个类型Details的ComboBox，其中我添加了一些细节类
public class Details {
private final StringProperty ministryOfWater;
private final StringProperty ministyOfLands;
public Details（String ministryOfWater，String ministyOfLands）{
this.ministryOfWater = new SimpleStringProperty（ministryOfWater）;
this.ministyOfLands = new SimpleStringProperty（ministyOfLands）;
}
public String getMinistryOfWater（）{
return ministryOfWater.get（）;
}
public void setMinistryOfWater（String ministryOfWater）{
this.ministryOfWater.set（ministryOfWater）;
}
public StringProperty ministryOfWaterProperty（）{
return ministryOfWater;
}
//完成的水服务
public String getMinistyOfLands（）{
return ministyOfLands.get（）;
}
public void setMinistyOfLands（String ministyOfLands）{
this.ministyOfLands.set（ministyOfLands）;
}
public StringProperty ministyOfLandsProperty（）{
return ministyOfLands;
}
//完成土地部门
@Override
public String toString（）{
return getMinistryOfWater（） + getMinistyOfLands（）;
}
}

如何显示从选定Combobox到此文本字段的不同文本，声明为
TextField txtActivity
i am stuck here
if（cmbComponent.getSelectionModel（）。getSelectedItem（）。equals（Ministry of Water））{
txtActivity.setText（1.0.0）;
}
需要帮助
谢谢！
EDIT
我已经得到这个链接的解决方案
如何设置文本从
解决方案
中选择一个项目时， >
向值属性添加侦听器：
cmbComponent.valueProperty（）。addListener（（observable，oldValue，newValue） - > {
txtActivity.setText（newValue == null？null：newValue.toString（））;
}）;
这样， TextField
创建绑定
txtActivity.textProperty ）.bind（Bindings.createStringBinding（（） - > {
详细信息d = cmbComponent.getValue（）;
return d == null？null：d.toString（）;
} ，cmbComponent.valueProperty（）））;
这样， TextField 不再可编辑
将 TextFormatter 添加到 TextField h3>
这允许双向绑定。这样，您可以根据 TextField 中的文本输入更改 ComboBox 值。
TextFormatter< Details> formatter = new TextFormatter<>（new StringConverter< Details>（）{
@Override
public String toString（Details object）{
return object == null？ ：object.toString（）;
}
@Override
public Details fromString（String string）{
//基于TextField中的String输入返回Details对象
return string == null || string.isEmpty（）？null：cmbComponent.getItems（）。stream（）。filter（d - > string.equals（d.toString（）））findAny orElse（null）;
}
}）;
txtActivity.setTextFormatter（formatter）;
cmbComponent.valueProperty（）。bindBidirectional（formatter.valueProperty（））;
So i want to get a selected item from a Combobox, after clicking on that selected item it should return a different text on a TextField in javafx. I am having a problem in doing so this is my code
I have a ComboBox of type Details , in which I have added few object of Details Class
public class Details {
private final StringProperty ministryOfWater ;
private final StringProperty ministyOfLands;
public Details(String ministryOfWater, String ministyOfLands) {
this.ministryOfWater = new SimpleStringProperty(ministryOfWater);
this.ministyOfLands = new SimpleStringProperty(ministyOfLands);
}
public String getMinistryOfWater() {
return ministryOfWater.get();
}
public void setMinistryOfWater(String ministryOfWater) {
this.ministryOfWater.set(ministryOfWater);
}
public StringProperty ministryOfWaterProperty() {
return ministryOfWater;
}
//finished ministry of water
public String getMinistyOfLands() {
return ministyOfLands.get();
}
public void setMinistyOfLands(String ministyOfLands) {
this.ministyOfLands.set(ministyOfLands);
}
public StringProperty ministyOfLandsProperty() {
return ministyOfLands;
}
//finished with the ministry of lands
@Override
public String toString() {
return getMinistryOfWater() + " " + getMinistyOfLands();
}
}
this is my full code

txtActivity.setText("1.0.0");
}
need help Thanks!
EDIT
I already got the solution from this link How to set text to a TextField when selecting an Item from a Combobox Javafx?
解决方案
Depending on your needs you could:
Add a listener to the value property:
cmbComponent.valueProperty().addListener((observable, oldValue, newValue) -> {
txtActivity.setText(newValue == null ? null : newValue.toString());
});
This way the TextField will remain editable after selecting the item.
Creating a Binding
txtActivity.textProperty().bind(Bindings.createStringBinding(() -> {
Details d = cmbComponent.getValue();
return d == null ? null : d.toString();
}, cmbComponent.valueProperty()));
This way the TextField is no longer editable.
Add a TextFormatter to the TextField
This allows bidirectional binding. This way you could change the ComboBox value based on the text input in the TextField.
TextFormatter<Details> formatter = new TextFormatter<>(new StringConverter<Details>() {
@Override
public String toString(Details object) {
return object == null ? "" : object.toString();
}
@Override
public Details fromString(String string) {
// Return Details object based on String input in TextField
return string == null || string.isEmpty() ? null : cmbComponent.getItems().stream().filter(d -> string.equals(d.toString())).findAny().orElse(null);
}
});
txtActivity.setTextFormatter(formatter);
cmbComponent.valueProperty().bindBidirectional(formatter.valueProperty());
