javafx GridPane检索特定的Cell内容 [英] javafx GridPane retrieve specific Cell content

问题描述

我想检索Gridpane中一个特定单元格的内容。我已将按钮放在单元格中

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....

在我的情况下， GridPane.getChildren.get（10）并不好。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

我想如果没有从gridpane获取特定节点的解决方案是列和行索引，我有一个函数来做到这一点，

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;
}
