我可以将ChangeListener添加到场景中，然后在scene.widthProperty（）和
scene.heightProperty（），但是当通过“最大化”按钮最大化窗口时，此方法不适用。
当像scene.getWindow（）一样访问窗口时，找不到窗口的onResize属性
这是我根据调整窗口大小来调整表中列大小的方法。
当整个窗口最大化时，如何使resizeColumns侦听器添加到其中（不符合scene.widthProperty（）或scene.heightProperty（）的条件）
ChangeListener<Object> resizeColumns = new ChangeListener<Object>(){
@Override
public void changed(ObservableValue arg0, Object arg1, Object arg2) {
new Thread() {
// runnable for that thread
public void run() {
Platform.runLater(new Runnable(){
public void run() {
// what will be ran in gui thread
Double width =primaryStage.getWidth();
DraftController controller = (DraftController)loader.getController();
TableView<Player> teamTable =controller.getTeamTable();
centerColumns(width, controller, teamTable);
TableView<Player> top10Table = controller.getTop10Table();
AnchorPane anchor = controller.getAnchorPane();
centerColumns(anchor.getWidth()+anchor.getWidth()*.04,controller,top10Table);
}
private void centerColumns(Double width, DraftController controller, TableView<Player> teamTable) {
ObservableList<TableColumn<Player, ?>> columnList = teamTable.getColumns();
for (int i=0 ; i<columnList.size(); i++){
columnList.get(i).setPrefWidth((width-17)/teamTable.getColumns().size());
}
}
});
}
}.start();
}
};
scene.widthProperty().addListener(resizeColumns);
scene.heightProperty().addListener(resizeColumns);

最佳答案
我的小例子很好地发挥了最大作用：
package org.example;
import javafx.application.Application;
import javafx.beans.InvalidationListener;
import javafx.beans.Observable;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class ResizeScene extends Application {
@Override
public void start(final Stage primaryStage) throws Exception {
final StackPane stack = new StackPane();
final Text resolution = new Text();
stack.getChildren().add(resolution);
final Scene scene = new Scene(stack);
primaryStage.setScene(scene);
final InvalidationListener resizeListener = new InvalidationListener() {
@Override
public void invalidated(final Observable observable) {
final double width = scene.getWidth();
final double height = scene.getHeight();
resolution.setText(width + " x " + height);
}
};
scene.widthProperty().addListener(resizeListener);
scene.heightProperty().addListener(resizeListener);
// Initial Size
primaryStage.setWidth(800);
primaryStage.setHeight(600);
primaryStage.show();
}
public static void main(final String[] args) {
launch(args);
}
}
关于java - 如何在JavaFX中的场景的最大化(不调整大小)上调用函数，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/19940504/
