javafx GridPane 检索特定的单元格内容

问题描述

我想检索网格窗格中一个特定单元格的内容.我已经将按钮放在带有

I want to retrieve the content of one specific cell in a Gridpane. I have put buttons in the cells with the

setConstraints(btt , 0 ,1 )

setConstraints(btt , 0 ,2 )

getChildren().add....

就我而言，GridPane.getChildren.get(10) 不好.我想直接进入单元格(4,2)并获取其内容.

In my case the GridPane.getChildren.get(10) is not good. I want to go directly to the cell(4,2) and get its content.

推荐答案

好吧，我想如果没有解决方案可以通过列和行索引从 gridpane 获取特定节点，我有一个函数可以做到这一点，

Well I guess if there is no solution to get a specific node from gridpane by is column and row index, I have a function to do that,

private Node getNodeFromGridPane(GridPane gridPane, int col, int row) {
    for (Node node : gridPane.getChildren()) {
        if (GridPane.getColumnIndex(node) == col && GridPane.getRowIndex(node) == row) {
            return node;
        }
    }
    return null;
}
