public class GridPane extends Pane
A child may be placed anywhere within the grid and may span multiple rows/columns. Children may freely overlap within rows/columns and their stacking order will be defined by the order of the gridpane's children list (0th node in back, last node in front).
GridPane may be styled with backgrounds and borders using CSS. See
Region
superclass for details.
A child's placement within the grid is defined by it's layout constraints:
Constraint | Type | Description |
---|---|---|
columnIndex | integer | column where child's layout area starts. |
rowIndex | integer | row where child's layout area starts. |
columnSpan | integer | the number of columns the child's layout area spans horizontally. |
rowSpan | integer | the number of rows the child's layout area spans vertically. |
If the row/column indices are not explicitly set, then the child will be placed in the first row/column. If row/column spans are not set, they will default to 1. A child's placement constraints can be changed dynamically and the gridpane will update accordingly.
The total number of rows/columns does not need to be specified up front as the gridpane will automatically expand/contract the grid to accommodate the content.
To use the GridPane, an application needs to set the layout constraints on the children and add those children to the gridpane instance. Constraints are set on the children using static setter methods on the GridPane class:
GridPane gridpane = new GridPane();
// Set one constraint at a time...
Button button = new Button();
GridPane.setRowIndex(button, 1);
GridPane.setColumnIndex(button, 2);
// or convenience methods set more than one constraint at once...
Label label = new Label();
GridPane.setConstraints(label, 3, 1); // column=3 row=1
// don't forget to add children to gridpane
gridpane.getChildren().addAll(button, label);
Applications may also use convenience methods which combine the steps of
setting the constraints and adding the children:
GridPane gridpane = new GridPane();
gridpane.add(new Button(), 2, 1); // column=2 row=1
gridpane.add(new Label(), 3, 1); // column=3 row=1
GridPane gridpane = new GridPane();
gridpane.getColumnConstraints().add(new ColumnConstraints(100)); // column 1 is 100 wide
gridpane.getColumnConstraints().add(new ColumnConstraints(200)); // column 2 is 200 wide
By default the gridpane will resize rows/columns to their preferred sizes (either
computed from content or fixed), even if the gridpane is resized larger than
its preferred size. If an application needs a particular row or column to
grow if there is extra space, it may set its grow priority on the RowConstraints
or ColumnConstraints object. For example:
GridPane gridpane = new GridPane();
ColumnConstraints column1 = new ColumnConstraints(100,100,Double.MAX_VALUE);
column1.setHgrow(Priority.ALWAYS);
ColumnConstraints column2 = new ColumnConstraints(100);
gridpane.getColumnConstraints().addAll(column1, column2); // first column gets any extra width
GridPane gridpane = new GridPane();
ColumnConstraints column1 = new ColumnConstraints();
column1.setPercentWidth(50);
ColumnConstraints column2 = new ColumnConstraints();
column2.setPercentWidth(50);
gridpane.getColumnConstraints().addAll(column1, column2); // each get 50% of width
If a percentage value is set on a row/column, then that value takes precedent and the
row/column's min, pref, max, and grow constraints will be ignored.
Note that if the sum of the widthPercent (or heightPercent) values total greater than 100, the values will be treated as weights. e.g. if 3 columns are each given a widthPercent of 50, then each will be allocated 1/3 of the gridpane's available width (50/(50+50+50)).
width | height | |
---|---|---|
minimum | left/right insets plus the sum of each column's min width. | top/bottom insets plus the sum of each row's min height. |
preferred | left/right insets plus the sum of each column's pref width. | top/bottom insets plus the sum of each row's pref height. |
maximum | Double.MAX_VALUE | Double.MAX_VALUE |
A gridpane's unbounded maximum width and height are an indication to the parent that it may be resized beyond its preferred size to fill whatever space is assigned to it.
GridPane provides properties for setting the size range directly. These properties default to the sentinel value USE_COMPUTED_SIZE, however the application may set them to other values as needed:
gridpane.setPrefSize(300, 300);
// never size the gridpane larger than its preferred size:
gridpane.setMaxSize(Region.USE_COMPUTED_SIZE, Region.USE_COMPUTED_SIZE);
Applications may restore the computed values by setting these properties back
to USE_COMPUTED_SIZE.
GridPane does not clip its content by default, so it is possible that childrens' bounds may extend outside its own bounds if a child's min size prevents it from being fit within it space.
Constraint | Type | Description |
---|---|---|
halignment | javafx.geometry.HPos | The horizontal alignment of the child within its layout area. |
valignment | javafx.geometry.VPos | The vertical alignment of the child within its layout area. |
hgrow | javafx.scene.layout.Priority | The horizontal grow priority of the child. |
vgrow | javafx.scene.layout.Priority | The vertical grow priority of the child. |
margin | javafx.geometry.Insets | Margin space around the outside of the child. |
By default the alignment of a child within its layout area is defined by the alignment set for the row and column. If an individual alignment constraint is set on a child, that alignment will override the row/column alignment only for that child. Alignment of other children in the same row or column will not be affected.
Grow priorities, on the other hand, can only be applied to entire rows or columns. Therefore, if a grow priority constraint is set on a single child, it will be used to compute the default grow priority of the encompassing row/column. If a grow priority is set directly on a RowConstraint or ColumnConstraint object, it will override the value computed from content.
