How to maintain GridPane's fixed-size after adding elemnts dynamically
- by Eviatar G.
I need to create board game that can be dynamically change.
Its size can be 5x5, 6x6, 7x7 or 8x8.
I am jusing JavaFX with NetBeans and Scene builder for the GUI.
When the user choose board size greater than 5x5 this is what happens:
This is the template on the scene builder before adding cells dynamically:
To every cell in the GridPane I am adding StackPane + label of the cell number:
@FXML
GridPane boardGame;
public void CreateBoard()
{
int boardSize = m_Engine.GetBoard().GetBoardSize();
int num = boardSize * boardSize;
int maxColumns = m_Engine.GetNumOfCols();
int maxRows = m_Engine.GetNumOfRows();
for(int row = 0; row < maxRows ; row++)
{
for(int col = maxColumns - 1; col >= 0 ; col--)
{
StackPane stackPane = new StackPane();
stackPane.setPrefSize(150.0, 200.0);
stackPane.getChildren().add(new Label(String.valueOf(num)));
boardGame.add(stackPane, col, row);
num--;
}
}
boardGame.setGridLinesVisible(true);
boardGame.autosize();
}
The problem is the stack panes's size on the GridPane are getting smaller.
I tried to set them equal minimum and maximum size but it didn't help they are still getting smaller.
I searched on the web but didn't realy find same problem as mine.
The only similar problem to mine was found here:
Dynamically add elements to a fixed-size GridPane in JavaFX
But his suggestion is to use TilePane and I need to use GridPane because this is a board game and it more easier to use GridPane when I need to do tasks such as getting to cell on row = 1 and column = 2 for example.
EDIT:
I removed the GridPane from the FXML and created it manually on the Controller but now it print a blank board:
@FXML
GridPane boardGame;
public void CreateBoard()
{
int boardSize = m_Engine.GetBoard().GetBoardSize();
int num = boardSize * boardSize;
int maxColumns = m_Engine.GetNumOfCols();
int maxRows = m_Engine.GetNumOfRows();
boardGame = new GridPane();
boardGame.setAlignment(Pos.CENTER);
Collection<StackPane> stackPanes = new ArrayList<StackPane>();
for(int row = 0; row < maxRows ; row++)
{
for(int col = maxColumns - 1; col >= 0 ; col--)
{
StackPane stackPane = new StackPane();
stackPane.setPrefSize(150.0, 200.0);
stackPane.getChildren().add(new Label(String.valueOf(num)));
boardGame.add(stackPane, col, row);
stackPanes.add(stackPane);
num--;
}
}
this.buildGridPane(boardSize);
boardGame.setGridLinesVisible(true);
boardGame.autosize();
boardGamePane.getChildren().addAll(stackPanes);
}
public void buildGridPane(int i_NumOfRowsAndColumns)
{
RowConstraints rowConstraint;
ColumnConstraints columnConstraint;
for(int index = 0 ; index < i_NumOfRowsAndColumns; index++)
{
rowConstraint = new RowConstraints(3, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, VPos.CENTER, true);
boardGame.getRowConstraints().add(rowConstraint);
columnConstraint = new ColumnConstraints(3, Control.USE_COMPUTED_SIZE, Double.POSITIVE_INFINITY, Priority.ALWAYS, HPos.CENTER, true);
boardGame.getColumnConstraints().add(columnConstraint);
}
}
