我想在GridPane中水平居中一行。我知道如何水平居中一列(root.getColumnConstraints().get(0).setHalignment(HPos.CENTER);
),但我无法找到行的这种方法。我只能更改列的Halignment属性和行的Valignment属性。但我需要的是行的Halignment,它不存在。那我怎么能这样做呢?
答案 0 :(得分:0)
对于整行的使用约束不可能这样做,但您可以使用GridPane.setHalignment
连续设置所有Node
的属性,该属性优先于ColumnConstraints
}。
示例
@Override
public void start(Stage primaryStage) {
Text text00 = new Text("text");
Text text01 = new Text("text");
Text text02 = new Text("text");
Text text10 = new Text("text");
Text text11 = new Text("text");
Text text12 = new Text("text");
GridPane gridPane = new GridPane();
ColumnConstraints cConstraints = new ColumnConstraints();
cConstraints.setHalignment(HPos.LEFT);
cConstraints.setHgrow(Priority.ALWAYS);
gridPane.getColumnConstraints().addAll(cConstraints, cConstraints);
gridPane.addColumn(0, text00, text01, text02);
gridPane.addColumn(1, text10, text11, text12);
GridPane.setHalignment(text11, HPos.CENTER);
GridPane.setHalignment(text01, HPos.CENTER);
Scene scene = new Scene(gridPane);
primaryStage.setScene(scene);
primaryStage.show();
}
请注意,您可以在将节点添加到GridPane
之后通过迭代子节点来执行此操作:
int alignRow = 1;
for (Node n : gridPane.getChildren()) {
Integer row = GridPane.getRowIndex(n);
int rowNumber = row == null ? 0 : rowNumber.intValue();
if (rowNumber = alignRow) {
GridPane.setHalignment(n, HPos.CENTER);
}
}
