JavaFX 27 · javafx.scene.layout.RowConstraints · APIdia, the JavaDoc alternative

Defines optional layout constraints for a row in a GridPane. If a RowConstraints object is added for a row in a gridpane, the gridpane will use those constraint values when computing the row's height and layout.

For example, to create a GridPane with 10 rows 50 pixels tall:

GridPane gridpane = new GridPane();
    for (int i = 0; i < 10; i++) {
        RowConstraints row = new RowConstraints(50);
        gridpane.getRowConstraints().add(row);
    }

Or, to create a GridPane where rows take 25%, 50%, 25% of its height:

GridPane gridpane = new GridPane();
    RowConstraints row1 = new RowConstraints();
    row1.setPercentHeight(25);
    RowConstraints row2 = new RowConstraints();
    row2.setPercentHeight(50);
    RowConstraints row3 = new RowConstraints();
    row3.setPercentHeight(25);
    gridpane.getRowConstraints().addAll(row1,row2,row3);

Note that adding an empty RowConstraints object has the effect of not setting any constraints, leaving the GridPane to compute the row's layout based solely on its content's size preferences and constraints.

Field Detail

fillHeight	back to summary
private BooleanProperty fillHeight The vertical fill policy for the row. The gridpane will use this property to determine whether nodes contained within the row should be expanded to fill the row's height or kept to their preferred heights. The default value is true.

fillHeight

back to summary

private BooleanProperty fillHeight

The vertical fill policy for the row. The gridpane will use this property to determine whether nodes contained within the row should be expanded to fill the row's height or kept to their preferred heights.

The default value is true.

maxHeight	back to summary
private DoubleProperty maxHeight The maximum height for the row. This property is ignored if percentHeight is set. The default value is USE_COMPUTED_SIZE, which means the maximum height will be computed to be the smallest maximum height of the row's content.

maxHeight

back to summary

private DoubleProperty maxHeight

The maximum height for the row. This property is ignored if percentHeight is set.

The default value is USE_COMPUTED_SIZE, which means the maximum height will be computed to be the smallest maximum height of the row's content.

minHeight	back to summary
private DoubleProperty minHeight The minimum height for the row. This property is ignored if percentHeight is set. The default value is USE_COMPUTED_SIZE, which means the minimum height will be computed to be the largest minimum height of the row's content.

minHeight

back to summary

private DoubleProperty minHeight

The minimum height for the row. This property is ignored if percentHeight is set.

The default value is USE_COMPUTED_SIZE, which means the minimum height will be computed to be the largest minimum height of the row's content.

percentHeight	back to summary
private DoubleProperty percentHeight The height percentage of the row. If set to a value greater than 0, the row will be resized to that percentage of the available gridpane height and the other size constraints (minHeight, prefHeight, maxHeight, vgrow) will be ignored. The default value is -1, which means the percentage will be ignored.

prefHeight	back to summary
private DoubleProperty prefHeight The preferred height for the row. This property is ignored if percentHeight is set. The default value is USE_COMPUTED_SIZE, which means the preferred height will be computed to be the largest preferred height of the row's content.

prefHeight

back to summary

private DoubleProperty prefHeight

The preferred height for the row. This property is ignored if percentHeight is set.

The default value is USE_COMPUTED_SIZE, which means the preferred height will be computed to be the largest preferred height of the row's content.

valignment	back to summary
private ObjectProperty<VPos> valignment The vertical alignment for the row. If set, will be the default vertical alignment for nodes contained within the row. If this property is set to VPos.BASELINE, then the fillHeight property will be ignored and nodes will always be resized to their preferred heights.

vgrow	back to summary
private ObjectProperty<Priority> vgrow The vertical grow priority for the row. If set, the gridpane will use this priority to determine whether the row should be given any additional height if the gridpane is resized larger than its preferred height. This property is ignored if percentHeight is set. This default value is null, which means that the row's grow priority will be derived from largest grow priority set on a content node.

vgrow

back to summary

private ObjectProperty<Priority> vgrow

The vertical grow priority for the row. If set, the gridpane will use this priority to determine whether the row should be given any additional height if the gridpane is resized larger than its preferred height. This property is ignored if percentHeight is set.

This default value is null, which means that the row's grow priority will be derived from largest grow priority set on a content node.
