QTextEdit and QTextBlock

[Garfeild]

Hi all.
I want to place two text blocks on one line in QTextEditor. I have tried several combinations with QTextFrame and QTextCursor but it is useless(
Code: http://pastebin.com/d82d4579
I want blabla2 with border and blabla near it.

Why not wrap them into a table?

So, i have tried code below. But when i use this method columns don't save their width. Any ideas?

QVector<QTextLength> columnWidth;
  for(int i=0; i<15; i++)
  { 
    if(i==0) 
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength,174));
    if(i>0 && i<10)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 42.25));
    else if(i>9 && i<12)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 118));
    else if(i==12 || i==14)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 100));
    else if(i==13)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 70));
  }
 
QTextTableFormat numberTableFormat;
numberTableFormat.setBorder(0);
numberTableFormat.setCellSpacing(-1);
numberTableFormat.setColumnWidthConstraints(columnWidth);
 
QTextTable *mainTable = cursor.insertTable(32, 15, numberTableFormat);
 
 
cursor = mainTable->cellAt(0,2).firstCursorPosition();
QTextFrameFormat tempFormat = cursor.currentFrame()->frameFormat();
tempFormat.setBorder(1);
cursor.insertFrame(tempFormat);
cursor.insertText("some text");

QVector<QTextLength> columnWidth;
  for(int i=0; i<15; i++)
  { 
    if(i==0) 
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength,174));
    if(i>0 && i<10)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 42.25));
    else if(i>9 && i<12)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 118));
    else if(i==12 || i==14)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 100));
    else if(i==13)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 70));
  }

QTextTableFormat numberTableFormat;
numberTableFormat.setBorder(0);
numberTableFormat.setCellSpacing(-1);
numberTableFormat.setColumnWidthConstraints(columnWidth);

QTextTable *mainTable = cursor.insertTable(32, 15, numberTableFormat);


cursor = mainTable->cellAt(0,2).firstCursorPosition();
QTextFrameFormat tempFormat = cursor.currentFrame()->frameFormat();
tempFormat.setBorder(1);
cursor.insertFrame(tempFormat);
cursor.insertText("some text");

Try setting the width also for the whole table.

[Garfeild]

I cannot find method to do this. Can you give me link?

[wysota]

The table is a frame so you can use QTextFrameFormat::setWidth() and apply it to the table.

I have tried this. But it doesn't work.

QVector<QTextLength> columnWidth;
  for(int i=0; i<15; i++)
  { 
    if(i==0) 
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength,174));
    if(i>0 && i<10)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 42.25));
    else if(i>9 && i<12)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 118));
    else if(i==12 || i==14)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 100));
    else if(i==13)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 70));
  }
 
  QTextTableFormat numberTableFormat;
  numberTableFormat.setBorder(0);
  numberTableFormat.setCellSpacing(-1);
  numberTableFormat.setColumnWidthConstraints(columnWidth);
  QBrush brush(Qt::black);
  numberTableFormat.setBorderBrush(brush);
  numberTableFormat.setBorderStyle(QTextFrameFormat::BorderStyle_Solid);
 //UPDATE 
 numberTableFormat.setWidth(824.25);
 
  QTextTable *mainTable = cursor.insertTable(32, 15, numberTableFormat);
  //SECOND OPTION:
  //mainTable->format().setWidth(824.25);
  cursor = mainTable->cellAt(0,2).firstCursorPosition();
  QTextFrameFormat tempFormat = cursor.currentFrame()->frameFormat();
  tempFormat.setBorder(1);
  cursor.insertFrame(tempFormat);
  cursor.insertText("1");

QVector<QTextLength> columnWidth;
  for(int i=0; i<15; i++)
  { 
    if(i==0) 
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength,174));
    if(i>0 && i<10)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 42.25));
    else if(i>9 && i<12)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 118));
    else if(i==12 || i==14)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 100));
    else if(i==13)
      columnWidth.append(QTextLength::QTextLength(QTextLength::FixedLength, 70));
  }

  QTextTableFormat numberTableFormat;
  numberTableFormat.setBorder(0);
  numberTableFormat.setCellSpacing(-1);
  numberTableFormat.setColumnWidthConstraints(columnWidth);
  QBrush brush(Qt::black);
  numberTableFormat.setBorderBrush(brush);
  numberTableFormat.setBorderStyle(QTextFrameFormat::BorderStyle_Solid);
 //UPDATE 
 numberTableFormat.setWidth(824.25);
  
  QTextTable *mainTable = cursor.insertTable(32, 15, numberTableFormat);
  //SECOND OPTION:
  //mainTable->format().setWidth(824.25);
  cursor = mainTable->cellAt(0,2).firstCursorPosition();
  QTextFrameFormat tempFormat = cursor.currentFrame()->frameFormat();
  tempFormat.setBorder(1);
  cursor.insertFrame(tempFormat);
  cursor.insertText("1");

Try building on this code:

QTextTableFormat tfmt;
tfmt.setBorder(0);
QTextCursor cursor(doc);
QTextTable *table = cursor.insertTable(1, 2, tfmt);
cursor = table->cellAt(0,0).firstCursorPosition();
tfmt.setBorder(1);
QTextTable *inner = cursor.insertTable(1,1, tfmt);
inner->cellAt(0,0).firstCursorPosition().insertText("blabla2");
table->cellAt(0,1).firstCursorPosition().insertText("blabla");

QTextTableFormat tfmt;
tfmt.setBorder(0);
QTextCursor cursor(doc);
QTextTable *table = cursor.insertTable(1, 2, tfmt);
cursor = table->cellAt(0,0).firstCursorPosition();
tfmt.setBorder(1);
QTextTable *inner = cursor.insertTable(1,1, tfmt);
inner->cellAt(0,0).firstCursorPosition().insertText("blabla2");
table->cellAt(0,1).firstCursorPosition().insertText("blabla");

Thnx! It's working.

[Garfeild]

I have new problem. I need to set cell height. I have tried to use QTextFrameFormat::setHeight(qreal height) but cells haven't resized. Also i tried to set height for whole table.

I have new problem. I need to set cell height. I have tried to use QTextFrameFormat::setHeight(qreal height) but cells haven't resized. Also i tried to set height for whole table.

is not possibel!
only if you subclass QAbstractTextDocumentLayout and on a protected function

void QAbstractTextDocumentLayout::drawInlineObject ( QPainter * painter, const QRectF & rect, QTextInlineObject object, int posInDocument, const QTextFormat & format ) [virtual protected]
Called to draw the inline object object on the given painter within the rectangle specified by rect using the text format specified by format. posInDocument specifies the position of the object within the document.

you can insert all your elements ... structure and draw method...

only Cell_Width is possibel to set ... if you work on layer based
table are not needet have a look on http://code.google.com/p/fop-miniscribus/
and his xhtml export .... !not IE

qreal QVimedit::Get_Cell_Width( QTextTableFormat TableFormat , int position )  
{
    qreal notfound = 0;
    QVector<QTextLength> constraints = TableFormat.columnWidthConstraints();
        for (int i = 0; i < constraints.size(); ++i) {
            if (i == position) {
                QTextLength langecell = constraints.value(i);
                 if (langecell.type() == QTextLength::FixedLength) {
                  return langecell.rawValue();
                 }                     
 
            }
        }
   return notfound;
}

qreal QVimedit::Get_Cell_Width( QTextTableFormat TableFormat , int position )  
{
    qreal notfound = 0;
    QVector<QTextLength> constraints = TableFormat.columnWidthConstraints();
        for (int i = 0; i < constraints.size(); ++i) {
            if (i == position) {
                QTextLength langecell = constraints.value(i);
                 if (langecell.type() == QTextLength::FixedLength) {
                  return langecell.rawValue();
                 }                     
                                     
            }
        }
   return notfound;

to insert other parameter to QTextBlock, QTextTableFormat , QTextImageFormat ... you can use QTextFormat::propertyi use this to save image data .... and i can save doc and image on not GUI QThread whitout use QPixmap.

QTextBlock::iterator de;
                 .............
                 Pics = block.toImageFormat();
                  if (Pics.isValid()) {
                  const QString hrefadress = Pics.name();
									QString titles;
                  QVariant inline_img_info = Pics.property(100);
                       if (!inline_img_info.isNull()) {
                          SPics pic = inline_img_info.value<SPics>();
                        }
                  }

QTextBlock::iterator de;
                 .............
                 Pics = block.toImageFormat();
                  if (Pics.isValid()) {
                  const QString hrefadress = Pics.name();
									QString titles;
                  QVariant inline_img_info = Pics.property(100);
                       if (!inline_img_info.isNull()) {
                          SPics pic = inline_img_info.value<SPics>();
                        }
                  }
