Class SpreadsheetCellBase

java.lang.Object

org.controlsfx.control.spreadsheet.SpreadsheetCellBase

All Implemented Interfaces:

javafx.event.EventTarget, SpreadsheetCell

public class SpreadsheetCellBase
extends java.lang.Object
implements SpreadsheetCell, javafx.event.EventTarget

The SpreadsheetCells serve as model for the SpreadsheetView.
You will provide them when constructing a Grid.

SpreadsheetCell Types

Each SpreadsheetCell has its own SpreadsheetCellType which has its own SpreadsheetCellEditor in order to control very closely the possible modifications.

Different SpreadsheetCellTypes are available depending on the data you want to represent in your SpreadsheetView. You can use the different static method provided in SpreadsheetCellType in order to create the specialized SpreadsheetCell that suits your need.

If you want to create a SpreadsheetCell of your own, you simply have to use one of the provided constructor. Usually you will let your SpreadsheetCellType create the cells. For example SpreadsheetCellType.StringType.createCell(int, int, int, int, java.lang.String). You will also have to provide a custom SpreadsheetCellEditor.

Configuration

You will have to indicate the coordinates of the cell together with the row and column span. You can specify if you want the cell to be editable or not using setEditable(boolean). Be advised that a cell with a rowSpan means that the cell will replace all the cells situated in the rowSpan range. Same with the column span.
So the best way to handle spanning is to fill your grid with unique cells, and then call at the end GridBase.spanColumn(int, int, int) or GridBase.spanRow(int, int, int). These methods will handle the span for you.

Format

Your cell can have its very own format. If you want to display some dates with different format, you just have to create a unique SpreadsheetCellType and then specify for each cell their format with setFormat(String). You will then have the guaranty that all your cells will have a LocalDate as a value, but the value will be displayed differently for each cell. This will also guaranty that copy/paste and other operation will be compatible since every cell will share the same SpreadsheetCellType.
Here an example :

 SpreadsheetCell cell = SpreadsheetCellType.DATE.createCell(row, column, rowSpan, colSpan,
         LocalDate.now().plusDays((int) (Math.random() * 10))); // Random value
 // given here
 final double random = Math.random();
 if (random < 0.25) {
     cell.setFormat("EEEE d");
 } else if (random < 0.5) {
     cell.setFormat("dd/MM :YY");
 } else {
     cell.setFormat("dd/MM/YYYY");
 }
 

Popup

Each cell can display a Popup when clicked. This is useful when some non editable cell wants to display several actions to take on the grid. This feature is completely different from the Filter. Filters are shown on one particular row whereas popup can be added to every cell.

Graphic

Each cell can have a graphic to display next to the text in the cells. Just use the setGraphic(Node) in order to specify the graphic you want. If you specify an ImageView, the SpreadsheetView will try to resize it in order to fit the space available in the cell. For example :

 cell.setGraphic(new ImageView(new Image(getClass().getResourceAsStream("icons/exclamation.png"))));
 

If you only want to only provide Graphics for visible cells (for example a WebView), you can toggle setCellGraphic(boolean) and provide the graphics with the factory in SpreadsheetView.setCellGraphicFactory(org.controlsfx.control.spreadsheet.CellGraphicFactory).
In addition to that, you can also specify another graphic property to your cell with activateCorner(org.controlsfx.control.spreadsheet.SpreadsheetCell.CornerPosition). This allow you to activate or deactivate some graphics on the cell in every corner. Right now it's a little red triangle but you can modify this in your CSS by using the "cell-corner" style class.

 .cell-corner.top-left{
     -fx-background-color: red;
     -fx-shape : "M 0 0 L 1 0 L 0 1 z";
 }
 

You can also customize the tooltip of your SpreadsheetCell by specifying one with setTooltip(java.lang.String).

Style with CSS

You can style your cell by specifying some styleClass with getStyleClass(). You just have to create and custom that class in your CSS stylesheet associated with your SpreadsheetView. Also note that all SpreadsheetCell have a "spreadsheet-cell" styleClass added by default. Here is a example :

 cell.getStyleClass().add("row_header");
 

And in the CSS:

  .spreadsheet-cell.row_header{
     -fx-background-color: #b4d4ad ;
     -fx-background-insets: 0, 0 1 1 0;
     -fx-alignment: center;
 }
 

Examples

Here is an example that uses all the pre-built SpreadsheetCellType types. The generation is random here so you will want to replace the logic to suit your needs.

 private SpreadsheetCell<?> generateCell(int row, int column, int rowSpan, int colSpan) {
     List<String> stringListTextCell = Arrays.asList("Shanghai","Paris","New York City","Bangkok","Singapore","Johannesburg","Berlin","Wellington","London","Montreal");
     final double random = Math.random();
     if (random < 0.10) {
         List<String> stringList = Arrays.asList("China","France","New Zealand","United States","Germany","Canada");
         cell = SpreadsheetCellType.LIST(stringList).createCell(row, column, rowSpan, colSpan, stringList.get((int) (Math.random() * 6)));
     } else if (random >= 0.10 && random < 0.25) {
         cell = SpreadsheetCellType.STRING.createCell(row, column, rowSpan, colSpan,stringListTextCell.get((int)(Math.random()*10)));
     } else if (random >= 0.25 && random < 0.75) {
         cell = SpreadsheetCellType.DOUBLE.createCell(row, column, rowSpan, colSpan,(double)Math.round((Math.random()*100)*100)/100);
     } else {
         cell = SpreadsheetCellType.DATE.createCell(row, column, rowSpan, colSpan, LocalDate.now().plusDays((int)(Math.random()*10)));
     }
     return cell;
 }

updateText

protected void updateText()

Update the text for the SpreadsheetView. This method is automatically called whenever the item property or the filter property has changed. In addition it can be called manually whenever an update of the text is necessary, e.g. in a case where the item itself has changed to such an amount that the text representation has changed aswell. In this case the item property itself has not changed, so no automatic text update will be triggered.
