JavaFx GridPane-如何居中元素 [英] JavaFx GridPane - how to center elements

问题描述

我有一个GridPane充满1个字母的标签.

I have a GridPane filled with 1-letter-labels.

这是一张图片:

这是代码:

int charSpacing = 1;
int charsInWidth = 28;
int charsInHeight = 16;

double charWidth = 15;
double charHeight = 20;

GridPane gp = new GridPane();
gp.setAlignment(Pos.CENTER);

Label[] tmp = new Label[charsInHeight*charsInWidth];

String text = "W";
int currArrPos = 0;

for(int y = 0; y < charsInHeight; y++) {
    HBox hbox = new HBox(charSpacing);

    for(int x = 0; x < charsInWidth; x++) {
        tmp[currArrPos] = new Label(text);
        tmp[currArrPos].setTextFill(Paint.valueOf("white"));

        tmp[currArrPos].setMinHeight(charHeight);
        tmp[currArrPos].setMinWidth(charWidth);
        tmp[currArrPos].setMaxHeight(charHeight);
        tmp[currArrPos].setMaxWidth(charWidth);

        tmp[currArrPos].setStyle("-fx-border-color: white;");
        hbox.getChildren().add(tmp[currArrPos++]);

        if(x%2 == 0){
            text = "I";
        } else{
            text = "W";
        }
    }
    gp.add(hbox, 1, y);
}
guiDisplay.getChildren().add(gp);

如何使字符居中?

我将它们放在HBox中并给了它们间距.我试图将标签的textAlignment设置为CENTER，但这当然不起作用.

I have put them in a HBox and gave them spacing. I tried to make the textAlignment of the label to CENTER, but that doesn't work of course.

我也尝试过:

gp.setAlignment(Pos.CENTER);

有人有想法吗?谢谢！

推荐答案

哦，这很容易.我在错误的地方对准了.添加此功能即可完成工作:

oh, that was easy. i did the alignment on the wrong place. adding this will do the job:

tmp[currArrPos].setAlignment(Pos.CENTER);

还是谢谢.
