这是我的布局看起来像with gridlines的样子，这是它在主窗口中看起来when I resize的样子，这就是我希望final result成为的样子。基本上，我需要一些有关如何使GridPane水平和/或垂直填充整个Stage的提示，而其某些单元格仍保持指定的宽度/高度。目前，我已经尝试了所有可以想到的方法，但仍然找不到解决方案。使用AnchorPane可能可以帮助我实现所需的结果，但是我仍在努力寻找方法。我不想使用SceneBuilder，因为我不喜欢“拖放”编程=）
@Override
public void start(final Stage primaryStage){
BorderPane border = new BorderPane();

grid.getColumnConstraints().add(new ColumnConstraints(70)); //column 3
grid.getColumnConstraints().add(new ColumnConstraints(100)); //column 4
grid.getColumnConstraints().add(new ColumnConstraints()); //column 5
grid.getColumnConstraints().add(new ColumnConstraints()); //column 6
grid.getColumnConstraints().add(new ColumnConstraints()); //column 7
grid.getColumnConstraints().add(new ColumnConstraints()); //column 8

我省去了我认为不必要的代码。谢谢！
最佳答案
我认为这会对您有所帮助。
您可以在Scene Builder的帮助下进行整理。首先，您需要为网格窗格设置约束。在下面的图片中，您可以进行设置。根据你的身边。
在这里，您可以保持要增加的一面。它也由fxml完成。
<GridPane AnchorPane.bottomAnchor="-15.0" AnchorPane.leftAnchor="161.0" AnchorPane.rightAnchor="270.0" AnchorPane.topAnchor="30.0">
这里AnchorPane.bottomAnchor =“-15.0”这是主要位置，现在当窗口调整大小时它们会散开...
如果要更改元素。可以使用网格窗格的withProperty（）。它是这样的。
GridPane pne =new GridPane();
pne.widthProperty().addListener(new ChangeListener<Number>
() {
@Override
public void changed(ObservableValue<? extends Number> ov, Number t, Number t1) {
System.out.println("now do here what you want with inner objects");
}
});
通过使用这些属性，您还可以更改网格窗格的内部元素和其他属性。
