我有一个JavaFX BorderPane，其中有一个GridPane用于保存内容。 GridPane由两列组成，一列为Text，Label（均在VBox中），另一列为Button。文本列应该是80％宽度，按钮列应该是20％宽度。 当我设置Text的文本并且它比列宽时，它会包裹到VBox的宽度。但是，当我更改窗口的大小以使其更宽，然后缩小窗口时，文本中的文本不会缩回。
您可以看到我尝试在wireListeners的{{1}}函数中限制宽度。我尝试了不同的组合，但没有任何工作。
这是我的代码：
发射器：
TestMainViewGUI：
package com.test.app;
import com.test.app.view.TestMainView;
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class TestGuiApplication extends Application {
@Override
public void start(Stage initialStage) throws Exception {
TestMainView mainView = new TestMainView();
initialStage.setScene(new Scene(mainView.getView(), 300, 300));
mainView.init();
initialStage.show();
}
public static void main(String args[]){
launch(args);
}
}
如何获取package com.test.app.view;
import javafx.geometry.Insets;
import javafx.scene.Parent;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.ColumnConstraints;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.VBox;
import javafx.scene.text.Text;
public class TestMainView {
private BorderPane borderPane;
private GridPane gridPane;
private VBox viewBox;
private VBox selectedItemsColumn;
private Label selectedItemsTitleLabel;
private Text selectedItemsList;
private Button goButton;
public TestMainView() {
this.borderPane = new BorderPane();
}
public void init() {
createView();
wireListeners();
}
public BorderPane createView(){
borderPane.setCenter(createCenterView());
return borderPane;
}
public void wireListeners(){
goButton.setOnMouseClicked((event) -> {
selectedItemsList.setText(selectedItemsList.getText() + "- X X X X X X");
});
//Tried the following listeners to prevent the text from growing otuside column size:
//Keep border pane width matched to Scene
borderPane.prefHeightProperty().bind(borderPane.getScene().heightProperty());
borderPane.prefWidthProperty().bind(borderPane.getScene().widthProperty());
//Set text wrapping width to bind to its VBox, this worked
selectedItemsList.wrappingWidthProperty().bind(selectedItemsColumn.widthProperty());
//Set VBox width to match the gridpane column width
selectedItemsColumn.prefWidthProperty().bind(gridPane.getColumnConstraints().get(0).percentWidthProperty());
}
public VBox createCenterView(){
viewBox = new VBox();
viewBox.getChildren().add(createGridView());
return viewBox;
}
public GridPane createGridView(){
gridPane = new GridPane();
selectedItemsColumn = new VBox();
selectedItemsTitleLabel = new Label("Selected items:");
selectedItemsList = new Text("X X X X X X");
selectedItemsColumn.getChildren().addAll(selectedItemsTitleLabel, selectedItemsList);
gridPane.add(selectedItemsColumn, 0, 0);
goButton = new Button("Go!");
gridPane.add(goButton, 1, 0);
ColumnConstraints col1 = new ColumnConstraints();
col1.setPercentWidth(80);
ColumnConstraints col2 = new ColumnConstraints();
col2.setPercentWidth(20);
gridPane.getColumnConstraints().addAll(col1, col2);
gridPane.setHgap(10);
gridPane.setVgap(10);
gridPane.setPadding(new Insets(10,10,10,10));
gridPane.setGridLinesVisible(true);
return gridPane;
}
public Parent getView(){
return borderPane;
}
}
的{{1}}内容以使其宽度与Text列的宽度相匹配而不会溢出列？
