如何使GridPane适应JavaFX中的标签宽度？

Question

I have added a few labels into GridPane and found, that long ones are shortened with ellipsis. While I would like long ones to push grid column width become wider as it occurs in MigLayout in Swing. Is it possible?

The function you are looking at is the "ALWAYS" value for parameter "hgrow" in columnconstraints. Check following code to understand how to use this functionnality in an fxml:

<GridPane xmlns:fx="http://javafx.com/fxml/1" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity"
          minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.40">
    <columnConstraints>
        <ColumnConstraints hgrow="ALWAYS" minWidth="10.0" prefWidth="100.0"/>
        <ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0"/>
    </columnConstraints>
    <rowConstraints>
        <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES"/>
        <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES"/>
        <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES"/>
    </rowConstraints>
    <children>
        <Label text="abcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabcabc" GridPane.rowIndex="1"/>
    </children> </GridPane>

Hope it helps.
