在ListView-Cell中激活WordWrap时,文本不会自动换行。这是一个例子:
public class ListBug extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
ListView<String> myList = new ListView<String>();
myList.setCellFactory(new Callback<ListView<String>, ListCell<String>>() {
@Override
public ListCell<String> call(ListView<String> param) {
return new ListCell<String>() {
@Override
public void updateItem(String item, boolean empty) {
setWrapText(true);
setText(item);
super.updateItem(item, empty);
}
};
}
});
for (int i = 0; i < 100; i++) {
myList.getItems()
.add("Lorem ipsum dolor sit amet, consectetur adipisicing elit, "
+ "sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. "
+ "Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris "
+ "nisi ut aliquip ex ea commodo consequat.");
}
primaryStage.setScene(new Scene(myList));
primaryStage.setTitle("ListWrapBug");
primaryStage.show();
}
}
正常情况下,单元格中的文本应该换行,但是整个文本都在一行中,并显示一个水平滚动条。
如何在列表单元格中使用WordWrap或这是JavaFX错误?
最佳答案
有完全一样的问题。这是对我有用的代码。
public class ListBug extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
ListView<String> myList = new ListView<String>();
myList.setCellFactory(new Callback<ListView<String>, ListCell<String>>() {
@Override
public ListCell<String> call(final ListView<String> list) {
return new ListCell<String>() {
{
Text text = new Text();
text.wrappingWidthProperty().bind(list.widthProperty().subtract(15));
text.textProperty().bind(itemProperty());
setPrefWidth(0);
setGraphic(text);
}
};
}
});
for (int i = 0; i < 100; i++) {
myList.getItems()
.add("Lorem ipsum dolor sit amet, consectetur adipisicing elit, "
+ "sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. "
+ "Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris "
+ "nisi ut aliquip ex ea commodo consequat.");
}
primaryStage.setScene(new Scene(myList));
primaryStage.setTitle("ListWrapBug");
primaryStage.show();
}
}
