当我运行JavaFx应用程序时,我有这种奇怪的行为:
正如您所看到的,元素没有正确对齐。我使用SceneBuilder创建了该视图,编辑器中没有这个空白。
我的观点由GridPane组成。 GridPane的右侧单元格(在图片上)每个都包含一个HBox,每个包含元素(按钮/文本字段)。我没有在这里配置任何特定的东西,我没有使用任何CSS。
这里是完整的FXML:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.text.*?>
<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="MyController">
<children>
<GridPane hgap="3.0" vgap="3.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
<columnConstraints>
<ColumnConstraints hgrow="NEVER" />
<ColumnConstraints hgrow="NEVER" />
<ColumnConstraints hgrow="ALWAYS" />
</columnConstraints>
<rowConstraints>
<RowConstraints vgrow="SOMETIMES" />
<RowConstraints vgrow="SOMETIMES" />
<RowConstraints vgrow="SOMETIMES" />
</rowConstraints>
<children>
<Label text="label1" />
<Label text="label2" GridPane.rowIndex="1" />
<Button defaultButton="true" mnemonicParsing="false" onAction="#handleGo" text="Go!" GridPane.rowIndex="2">
<graphic>
<TextField fx:id="iterations" alignment="CENTER" prefWidth="43.0" style="-fx-padding: 0.166667em 0.333333em 0.166667em 0.333333em;" text="50000" />
</graphic></Button>
<Button fx:id="selectFileButton" maxWidth="1.7976931348623157E308" mnemonicParsing="false" onAction="#handleFileSelection" text="Select file" GridPane.columnIndex="1" GridPane.rowIndex="1" />
<HBox spacing="3.0" GridPane.columnIndex="2">
<children>
<TextField fx:id="customValue" editable="false" HBox.hgrow="ALWAYS" />
<Button fx:id="deleteButton" mnemonicParsing="false" onAction="#handleDelete" text="Delete" visible="false" />
</children>
</HBox>
<HBox spacing="3.0" GridPane.columnIndex="2" GridPane.rowIndex="1">
<children>
<Button fx:id="editButton" mnemonicParsing="false" text="Edit" />
<Button mnemonicParsing="false" text="New" />
</children>
</HBox>
<ComboBox fx:id="selection" maxWidth="1.7976931348623157E308" onAction="#handleSelection" GridPane.columnIndex="1" />
</children>
</GridPane>
</children>
</AnchorPane>
我错过了什么吗?
答案 0 :(得分:1)
GridPane
中的控件的默认对齐方式(可能一般用于控件?)为CENTER_LEFT
,而对于HBox
,默认为TOP_LEFT
。添加
alignment="CENTER_LEFT"
到您的HBox
应正确对齐它们。
