问题描述

我有一个简单的问题.网格可以自动调整其中的对象大小以适应网格吗?

I have a simple question. Can a grid automatically resize the objects in it to fit the grid?

我想在一个网格上设置一个 max_height 和 max_width 以及一个 min-width 和 min-height 并在我的窗口中将该网格居中.

I want to set a max_height and max_width on a grid as well as a min-width and min-height and center that grid in my window.

在我的网格中,我想在所有位置添加 Spacer Square.每个垫片都有一个边框.所以它看起来像一个实际的网格.

In my grid, I want to add Spacer Square in all spots. Each spacer has a border. So it will look like an actual grid.

如果我的网格是 4x4,我希望有 16 个大正方形.

If my grid is 4x4, I want there to be 16 big squares.

如果我的网格是 16x18,我希望有 288 个方格.

If my grid is 16x18, I want there to be 288 squares.

两个选项都应占用一定数量的区域,288 平方选项的正方形比 16 选项小很多,以适应我的网格尺寸.

Both options should take up an area of a set amount, the 288 square option having squares a lot smaller than the 16 option in order to fit my grid dimensions.

我检查了 gridpane 文档,但我很困惑是否有适合我的选项.我不知道填充、边距、setmaxwidth、setmaxheight 之间的区别(试过这个,没有改变).

I checked the gridpane documentation, but am confused if there is an option for me. I don't know the difference between padding, margins, setmaxwidth, setmaxheight (tried this, didnt change a thing).

double dimension_x=100; //max_width of actual square/spacer/gridspace
double dimension_y=100; //max_height of actual square/spacer/gridspace

int grid_x=100; //number of rows
int grid_y=100; //number of columns
Rectangle[][] rectangles = new Rectangle[grid_x][grid_y];

GridPane grid = new GridPane();
double grid_max_x=800;
double grid_max_y=600;
grid.setHgap(1);
grid.setVgap(1);
grid.setPadding(new Insets(16)); //not sure what this does. Attempt Fail
grid.setEffect(addEffect(Color.web("#202C2F"), .61, 12));
grid.setMaxHeight(grid_max_y); //does nothing that it APPEARS to me

for (int x=0;x<grid_x;x++)
{
    for(int y=0;y<grid_y;y++)
    {
        Rectangle temp = new Rectangle(dimension_x,dimension_y);
        grid.add(temp,x,y);
    }
}

推荐答案

如果您想要一个可调整大小的矩形字段,则不需要网格.只需将它们放在窗格上并绑定到窗格大小:

If you want a field of resizable rectangles you don't need a grid. Just put them on Pane and bind to the pane size:

public void start(Stage stage) {
    Pane root = new Pane();

    final int count = 7; //number of rectangles

    NumberBinding minSide = Bindings
            .min(root.heightProperty(), root.widthProperty())
            .divide(count);

    for (int x = 0; x < count; x++) {
        for (int y = 0; y < count; y++) {
            Rectangle rectangle = new Rectangle(0, 0, Color.LIGHTGRAY);

            rectangle.xProperty().bind(minSide.multiply(x));
            rectangle.yProperty().bind(minSide.multiply(y));
            rectangle.heightProperty().bind(minSide.subtract(2));
            rectangle.widthProperty().bind(rectangle.heightProperty());
            root.getChildren().add(rectangle);
        }
    }

    stage.setScene(new Scene(root, 500, 500));
    stage.show();
}
