问题描述
我正在使用itext生成可编辑的日历pdf。
我正在尝试使用此代码将TextField添加到PdfPCell ，
//为特定日期创建PdfPCell
public PdfPCell getDayCell（日历日历，区域设置区域设置）{
PdfPCell cell = new PdfPCell（） ;
cell.setPadding（ 3 ）;
// 根据日期类型设置背景颜色
< span class =code-keyword> if （isSunday（calendar））
cell.setBackgroundColor（BaseColor.GRAY）;
else if （isSpecialDay（calendar））
cell.setBackgroundColor（BaseColor。浅灰）;
else
cell.setBackgroundColor（BaseColor.WHITE）;
// 以语言环境的语言设置内容
Chunk chunk = new 块（ String .format（locale， ％1 $ ta，calendar），small）;
chunk.setTextRise（ 5 ）;
// 带有日期的段落
段落p = new 段落（chunk）;
// 分隔符
p.add（ new 块（ new VerticalPositionMark（）））;
// 和当天的数量
p.add（ new 块（ String .format（locale， ％1 $ te，calendar），normal））;
cell.addElement（p）;
cell.setCellEvent（ new MyCellField（locale + +日历））;
cell.setFixedHeight（ 80 ）;
返回单元格;
}
//将TextField添加到cellEvent
class MyCellField implements PdfPCellEvent {
protected String fieldname;
public MyCellField（ String fieldname）{
此 .fieldname = fieldname;
}
public void cellLayout（PdfPCell单元格，矩形矩形，PdfContentByte []画布）{
final PdfWriter writer = canvases [ 0 ]。getPdfWriter（ ）;
final TextField textField = new TextField（writer，rectangle） ，fieldname）;
textField.setAlignment（Element.ALIGN_TOP）;
textField.setOptions（TextField.MULTILINE）;
尝试 {
final PdfFormField field = textField.getTextField（）;
writer.addAnnotation（field）;
} catch （ final IOException ioe）{
throw new ExceptionConverter（ioe）;
} catch （ final DocumentException de）{
throw new ExceptionConverter（de）;
}
}
}
当我渲染日历pdf时，Cell焦点是垂直的，不是水平的。请帮助我找出我所缺少的东西。

注意：我使用iText5
我尝试过：
我试过了，
float textboxheight = 12f;
矩形矩形=矩形;
rect.Bottom = rect.Top - textboxheight;
rect.Bottom显示错误最后一个字段Rectangle.BOTTOM无法分配。

I'm using itext to generate editable Calendar pdf.
I'm trying to add TextField to the PdfPCell using this code,
//To create PdfPCell for a specific day
public PdfPCell getDayCell(Calendar calendar, Locale locale) {
PdfPCell cell = new PdfPCell();
cell.setPadding(3);
// set the background color, based on the type of day
if (isSunday(calendar))
cell.setBackgroundColor(BaseColor.GRAY);
else if (isSpecialDay(calendar))
cell.setBackgroundColor(BaseColor.LIGHT_GRAY);
else
cell.setBackgroundColor(BaseColor.WHITE);
// set the content in the language of the locale
Chunk chunk = new Chunk(String.format(locale, "%1$ta", calendar), small);
chunk.setTextRise(5);
// a paragraph with the day
Paragraph p = new Paragraph(chunk);
// a separator
p.add(new Chunk(new VerticalPositionMark()));
// and the number of the day
p.add(new Chunk(String.format(locale, "%1$te", calendar), normal));
cell.addElement(p);
cell.setCellEvent(new MyCellField(locale+""+calendar));
cell.setFixedHeight(80);
return cell;
}
// Adding TextField to the cellEvent
class MyCellField implements PdfPCellEvent {
protected String fieldname;
public MyCellField(String fieldname) {
this.fieldname = fieldname;
}
public void cellLayout(PdfPCell cell, Rectangle rectangle, PdfContentByte[] canvases) {
final PdfWriter writer = canvases[0].getPdfWriter();
final TextField textField = new TextField(writer, rectangle, fieldname);
textField.setAlignment(Element.ALIGN_TOP);
textField.setOptions(TextField.MULTILINE);
try {
final PdfFormField field = textField.getTextField();
writer.addAnnotation(field);
} catch (final IOException ioe) {
throw new ExceptionConverter(ioe);
} catch (final DocumentException de) {
throw new ExceptionConverter(de);
}
}
}
