JavaFX：舞台的minHeight考虑标题栏的高度 [英] JavaFX: stage's minHeight considering titlebar's height

问题描述

我目前正在为个人目的构建一个小型UI应用程序，但我遇到了一个问题。下面是一些代码：

I'm currently building a small UI application for personal purpose and I ran into a problem. Here is some code:

public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getClassLoader().getResource("ui.fxml"));

    Scene scene = new Scene(root);

    stage.setTitle("My app");
    stage.setScene(scene);
    stage.setMinHeight(608.0);
    stage.setMinWidth(1080.0);

    stage.show();
}

以下是与之相关的FXML代码：

And here's the FXML code assiociated with:

<GridPane gridLinesVisible="true" minHeight="608.0" minWidth="1080.0" xmlns="http://javafx.com/javafx/8.0.112" xmlns:fx="http://javafx.com/fxml/1" fx:controller="my.package.MyClass">
    <rowConstraints>
        <RowConstraints minHeight="500.0" prefHeight="500.0" vgrow="ALWAYS" />
        <RowConstraints maxHeight="108.0" minHeight="108.0" prefHeight="108.0" vgrow="NEVER" />
    </rowConstraints>
</GridPane>

所以，我的问题是，在启动时，GridPane的有效高度 608px 但仍可调整到较小的高度。事实上，它将可以重新调整，直到阶段将 608px ，包括标题栏的高度......

So, my problem is that, at launch, the GridPane will effectively have a height of 608px but is still resizable to a smaller height. Indeed, it will be resizable until the stage will be 608px, including the title bar's height...

我想要的行为是我的GridPane的高度不能小于 608.0 。

The behaviour I would like to have is that my GridPane can't have a smaller height than 608.0.

你知道怎么办？
非常感谢提前！

Do you know any ways to do that? Many thanks in advance!

推荐答案

正如@James_D在评论中指出的那样，我只需要修改我的代码如下所示：

As @James_D pointed out in a comment, I simply had to modify my code as follow:

public void start(Stage stage) throws Exception {
    Parent root = FXMLLoader.load(getClass().getClassLoader().getResource("ui.fxml"));

    Scene scene = new Scene(root);

    stage.setTitle("My app");
    stage.setScene(scene);

    stage.show();

    stage.setMinHeight(stage.getHeight());
    stage.setMinWidth(stage.getWidth());
}
