我需要将自定义 JavaFX 控件添加到代码中的网格窗格中。我设置了网格窗格的行和列约束，如下所示：

//These are doubles for the purposes of calculating more accurate percentages, see below.
//I feel like there should be a better way to accomplish this but I only want 5
//players per row, so the number of columns would be between 1 and 5 depending on the
//number of players, but if there are 5 or more, modulus doesn't work (5 % 5 = 0)... 
//I'm really bothered by this bit but it was the best I could devise.
double ColumnCount = Math.min(5, this.Settings.PlayerCount());
//This I feel fine with.
double RowCount = this.Settings.PlayerCount() / 5;

//The method encapsulating this code is for starting a new game. 
//This bit is for capturing player names for reassignment.
ArrayList<String> Names = new ArrayList<>();
if (this.Players.size()> 0)
    this.Players.stream().forEach((EQLPlayer plr) ->
        Names.add(plr.PlayerName())
    );

//This is for clearing the fields so they can be repopulated appropriately.
this.Players.clear();
this.gpPlayerField.getChildren().clear(); //<---- gpPlayerField is the GridPane with which I am working that I am trying to populate.
this.gpPlayerField.getColumnConstraints().clear();
this.gpPlayerField.getRowConstraints().clear();

//This bit is for setting up the Column and Row constraints.
for (int x = 0; x < ColumnCount; x++){
    ColumnConstraints CC = new ColumnConstraints();
    CC.setMaxWidth(200.00);
    CC.setPercentWidth( 100.00 / ColumnCount );
    CC.setHgrow(Priority.ALWAYS);
    this.gpPlayerField.getColumnConstraints().add(CC);
}
for (int x = 0; x < RowCount; x++){
    RowConstraints RC = new RowConstraints();
    RC.setMaxHeight(100.00);
    RC.setPercentHeight( 100.00 / RowCount );
    RC.setVgrow(Priority.ALWAYS);
    this.gpPlayerField.getRowConstraints().add(RC);
}

这是问题区域（我认为，其余的代码是为了以防我错过了一些愚蠢的明显的东西。

//I really feel like this should be working but it isn't.
//I want the rows and columns constrained to the size of the GridPane 
//(which is constrained to the stage) so that they will grow and shrink with it, but
//they are pretty much ignoring it.
for (int x = 0; x < this.Settings.PlayerCount(); x++){
    EQLPlayer plr = new EQLPlayer(x + 1);
    plr.GameMode(this.Settings.Mode());
    if (x < Names.size()) plr.PlayerName(Names.get(x));
    this.gpPlayerField.add(plr, x % 5, x / 5);
    GridPane.setHgrow(plr, Priority.ALWAYS);
    GridPane.setVgrow(plr, Priority.ALWAYS);
}

因此，我添加的控件具有绑定到它们的方法，这些方法将在控件大小更改时重新调整所有标签。当他们只是在舞台或场景上时，这很好用，但现在它不起作用，因为他们只是忽略了约束，我不确定为什么。我真的找不到一个例子来证明我需要做什么。我在这里检查并按照示例进行操作，但这也不起作用。所以......我在这里做错了什么？有没有更好的方法来实现我正在寻找的结果？

好吧，所以我所做的一切都是正确的。我遇到的问题是自定义控件最小尺寸和最大尺寸设置不正确。为了使这项工作（以防万一将来有人遇到这种情况），请确保您的最小尺寸（X 和 Y）和最大尺寸（再次）设置得当。
