如何在 JavaFX 的按钮中显示文本?

How can i show text in a Button in JavaFX?

我正在尝试在左上角的那 3 个按钮上显示一些文本,但不知怎么的,这是不可能的...

这是图片,您可以看到按钮的位置:

我已经尝试过的:

这是 FXML 片段:

<HBox fx:id="buttons_group" alignment="CENTER_LEFT" prefHeight="22.0" spacing="7" style="-fx-padding: 0 0 0 8" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.5" AnchorPane.topAnchor="0.0">

                  <Button fx:id="closebtn" text="×" textFill="black" onMouseClicked="#onClickCloseBtn" style="-fx-background-radius: 50; -fx-min-height: 9; -fx-min-width: 9; -fx-max-height: 9; -fx-max-width: 9; -fx-background-color: #FF453A" />
                  <Button fx:id="minimizebtn" text="-" textFill="black" onMouseClicked="#onClickMinimizeBtn" style="-fx-background-radius: 50; -fx-min-height: 9; -fx-min-width: 9; -fx-max-height: 9; -fx-max-width: 9; -fx-background-color: #FFD60A" />
                  <Button fx:id="maximizebtn" text="□" textFill="black" onMouseClicked="#onClickMaximizeBtn" style="-fx-background-radius: 50; -fx-min-height: 9; -fx-min-width: 9; -fx-max-height: 9; -fx-max-width: 9; -fx-background-color: #32D74B" />
        </HBox

谢谢!

为您的按钮设置负边距。

您可能还想减小字体大小,因为默认值为 12px,而您的按钮大小为 9px。

虽然如此小的按钮居中并不完美...

这是在 SceneBuilder 中完成的示例。

  <HBox alignment="CENTER_LEFT" prefHeight="22.0" spacing="7.0" style="-fx-background-color: #333;">
     <children>
        <Button maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" mnemonicParsing="false" prefHeight="9.0" prefWidth="9.0" style="-fx-background-radius: 4.5; -fx-background-color: #FF453A; -fx-padding: -100;" text="x">
           <font>
              <Font size="10.0" />
           </font>
        </Button>
        <Button maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" mnemonicParsing="false" prefHeight="9.0" prefWidth="9.0" style="-fx-background-radius: 4.5; -fx-background-color: #FFD60A; -fx-padding: -100;" text="-">
           <font>
              <Font size="10.0" />
           </font>
        </Button>
        <Button maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" mnemonicParsing="false" prefHeight="9.0" prefWidth="9.0" style="-fx-background-radius: 4.5; -fx-background-color: #32D74B; -fx-padding: -100;" text="□">
           <font>
              <Font size="10.0" />
           </font>
        </Button>
     </children>
     <padding>
        <Insets bottom="7.0" left="7.0" right="7.0" top="7.0" />
     </padding>
  </HBox>

结果:
