I initialized a GridPane through SceneBuilder and inside the controller I want to conditionally add a row to the GridPane. I do not want to store an int for how many rows I initialized, I want to be able to get the number of rows from the GridPane object. Is that possible?
Hej j will, try this method:
private int getRowCount(GridPane pane) {
int numRows = pane.getRowConstraints().size();
for (int i = 0; i < pane.getChildren().size(); i++) {
Node child = pane.getChildren().get(i);
if (child.isManaged()) {
Integer rowIndex = GridPane.getRowIndex(child);
if(rowIndex != null){
numRows = Math.max(numRows,rowIndex+1);
}
}
}
return numRows;
}
This worked for me.
