word wrapping is not working in BB with custom GridField Manager

Question

I am using Custom GridField Manager to display Details in 2 columns, with specified width. When Value of right side is too big then value is not wrapping to next line.

Here is my class of Custom GridField Manager.

public class CustomGridFieldManager extends Manager {
private int[] columnWidths;
private int columns;
private int allRowHeight = -1;


public CustomGridFieldManager(int columns, long style) {
    super(style);
    this.columns = columns;
}


public CustomGridFieldManager(int[] columnWidths, long style) {
    super(style);
    this.columnWidths = columnWidths;
    this.columns = columnWidths.length;

}

public CustomGridFieldManager(int[] columnWidths, int rowHeight, long style) {
    this(columnWidths, style);
    this.allRowHeight  = rowHeight;
}

protected boolean navigationMovement(int dx, int dy, int status, int time) {

    int focusIndex = getFieldWithFocusIndex();
    while(dy > 0) {
        focusIndex += columns;
        if (focusIndex >= getFieldCount()) {
            return false; // Focus moves out of this manager
        }
        else {
            Field f = getField(focusIndex);
            if (f.isFocusable()) { // Only move the focus onto focusable fields
                f.setFocus();
                dy--;
            }
        }
    }
    while(dy < 0) {
        focusIndex -= columns;
        if (focusIndex < 0) {
            return false;
        }
        else {
            Field f = getField(focusIndex);
            if (f.isFocusable()) {
                f.setFocus();
                dy++;
            }
        }
    }

    while(dx > 0) {
        focusIndex ++;
        if (focusIndex >= getFieldCount()) {
            return false;
        }
        else {
            Field f = getField(focusIndex);
            if (f.isFocusable()) {
                f.setFocus();
                dx--;
            }
        }
    }
    while(dx < 0) {
        focusIndex --;
        if (focusIndex < 0) {
            return false;
        }
        else {
            Field f = getField(focusIndex);
            if (f.isFocusable()) {
                f.setFocus();
                dx++;
            }
        }
    }
    return true;
}

protected void sublayout(int width, int height) {
    int y = 0;
    if (columnWidths == null) {
        columnWidths = new int[columns];
        for(int i = 0; i < columns; i++) {
            columnWidths[i] = width/columns;
        }
    }
    Field[] fields = new Field[columnWidths.length];
    int currentColumn = 0;
    int rowHeight = 0;
    for(int i = 0; i < getFieldCount(); i++) {
        fields[currentColumn] = getField(i);
        layoutChild(fields[currentColumn], columnWidths[currentColumn], height-y);
        if (fields[currentColumn].getHeight() > rowHeight) {
            rowHeight = fields[currentColumn].getHeight();
        }
        currentColumn++;
        if (currentColumn == columnWidths.length || i == getFieldCount()-1) {
            int x = 0;
            if (this.allRowHeight >= 0) {
                rowHeight = this.allRowHeight;
            }
            for(int c = 0; c < currentColumn; c++) {
                long fieldStyle = fields[c].getStyle();
                int fieldXOffset = 0;
                long fieldHalign = fieldStyle & Field.FIELD_HALIGN_MASK;
                if (fieldHalign == Field.FIELD_RIGHT) {
                    fieldXOffset = columnWidths[c] - fields[c].getWidth();
                }
                else if (fieldHalign == Field.FIELD_HCENTER) {
                    fieldXOffset = (columnWidths[c]-fields[c].getWidth())/2;
                }

                int fieldYOffset = 0;
                long fieldValign = fieldStyle & Field.FIELD_VALIGN_MASK;
                if (fieldValign == Field.FIELD_BOTTOM) {
                    fieldYOffset = rowHeight - fields[c].getHeight();
                }
                else if (fieldValign == Field.FIELD_VCENTER) {
                    fieldYOffset = (rowHeight-fields[c].getHeight())/2;
                }

                setPositionChild(fields[c], x+fieldXOffset, y + fieldYOffset);
                x += columnWidths[c];
            }
            currentColumn = 0;
            y += rowHeight;
        }
        if (y >= height) {
            break;
        }
    }
    int totalWidth = 0;
    for(int i = 0; i < columnWidths.length; i++) {
        totalWidth += columnWidths[i];
    }
    setExtent(totalWidth, Math.min(y, height));
}

In another Class, I use this custom GridField Manager Class.

int[] width = { (int) (Display.getWidth() / 2.9),
                    (int) (Display.getWidth() / 1.1) };

          final CustomGridFieldManager gfm_transactioninfo = new CustomGridFieldManager(
                    width, 35, Manager.VERTICAL_SCROLL | Manager.FIELD_HCENTER
                            | FOCUSABLE) {
                protected void paint(Graphics graphics) {
                    // TODO Auto-generated method stub
                    graphics.setColor(AppData.color_black);
                    super.paint(graphics);
                }

            };
            gfm_transactioninfo.setMargin(10, 0, 0, 10);// set top and left margin

I add Labelfiled like this,

lbl_CustEmail = new LabelField("Customer Email", LabelField.FOCUSABLE);
            lbl_CustEmail.setFont(label_font);

            value_CustEmail = new LabelField(": " +trandtail[0].getFromEmail());
            value_CustEmail.setFont(label_font);

gfm_transactioninfo.add(lbl_CustEmail);
                        gfm_transactioninfo.add(value_CustEmail);

If any 1 has idea then pls Help.

Answer 1

You are dividing width into two parts.. but my suggestion is you should divide width into three parts. like

int[] width = { (int) (Display.getWidth() / 3.2),
                    (int) (Display.getWidth() / 32),(int) (Display.getWidth() / 1.6) };

And differentiate " : " with new Label Field.

Here is my suggested code.. I had already tried and it works fine..

int[] width = { (int) (Display.getWidth() / 3.2),
                    (int) (Display.getWidth() / 32),(int) (Display.getWidth() / 1.6) };

            final CustomGridFieldManager gfm_transactioninfo = new CustomGridFieldManager(
                    width,45, Manager.VERTICAL_SCROLL | Manager.FIELD_HCENTER
                            | FOCUSABLE) {
                protected void paint(Graphics graphics) {
                    // TODO Auto-generated method stub
                    graphics.setColor(AppData.color_black);
                    super.paint(graphics);
                }

            };
            gfm_transactioninfo.setMargin(10, 10, 0, 10);// set top and left margin

lbl_CustEmail = new LabelField("Customer Email", LabelField.FOCUSABLE);
                lbl_CustEmail.setFont(label_font);

            value_CustEmail = new LabelField(proTransaction_details.getFromEmail() );
            value_CustEmail.setFont(label_font);

gfm_transactioninfo.add(lbl_CustEmail);
                        gfm_transactioninfo.add(new LabelField(" : "));
                        gfm_transactioninfo.add(value_CustEmail);

And your CustomGridFieldManager Class is perfect..

Just cheer up.. :)
