Class RowConstraints

java.lang.Object

javafx.scene.layout.ConstraintsBase

javafx.scene.layout.RowConstraints

public class RowConstraints
extends ConstraintsBase

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 width:

     GridPane gridpane = new GridPane();
     RowConstraints row1 = new RowConstraints();
     row1.setPercentWidth(25);
     RowConstraints row2 = new RowConstraints();
     row2.setPercentWidth(50);
     RowConstraints row3 = new RowConstraints();
     row3.setPercentWidth(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.

Constructor Detail

RowConstraints

public RowConstraints()

Creates a row constraints object with no properties set.

RowConstraints

public RowConstraints(double height)

Creates a row constraint object with a fixed height. This is a convenience for setting the preferred height constraint to the fixed value and the minHeight and maxHeight constraints to the USE_PREF_SIZE flag to ensure the row is always that height.

Parameters:

height - the height of the row

RowConstraints

public RowConstraints(double minHeight,
                      double prefHeight,
                      double maxHeight)

Creates a row constraint object with a fixed size range. This is a convenience for setting the minimum, preferred, and maximum height constraints.

RowConstraints

public RowConstraints(double minHeight,
                      double prefHeight,
                      double maxHeight,
                      Priority vgrow,
                      VPos valignment,
                      boolean fillHeight)

Creates a row constraint object with a fixed size range, vertical grow priority, vertical alignment, and vertical fill behavior.
