QTextCharFormat question

[moez]

Hi,
This is a question for experimented qt scribe classes programmers.

I am trying to simulate check box widget inside my rich text.

so i have created a QTextObjectInterface that paint this 'check box' for me. I do store the 'check state' inside the a custom QTextChartFormat created for with this interface.

bool isChecked = false;
QTextCharFormat format = cursor.blockCharFormat();
format.setObjectType(CheckBoxTextFormat);
//CheckBox::CB_IsChecked  
format.setProperty(CheckBox::CB_IsChecked,isChecked);

bool isChecked = false;
QTextCharFormat format = cursor.blockCharFormat();
format.setObjectType(CheckBoxTextFormat);
//CheckBox::CB_IsChecked  
format.setProperty(CheckBox::CB_IsChecked,isChecked);

To copy to clipboard, switch view to plain text mode 

When user click the 'checkbox' i do call this code to simulate a click

// QTextCursor cursor, QTextCharFormat format are in the right position  where i have my QTextObject
 
  bool isChecked  = format.property(CheckBox::CB_IsChecked).toBool();   
  isChecked = !isChecked;
  format.setProperty(CheckBox::CB_IsChecked,QVariant(isChecked));
  cursor.beginEditBlock();
  cursor.mergeCharFormat(format); //for some reason this don't work
  cursor.cursor.setCharFormat(format); // also this don't work  
  //  when painting the QTextObjectInterface  read always the same value from   format.property(CheckBox::CB_IsChecked).toBool();   
// even if it was changed by  above code.  
cursor.endEditBlock();

// QTextCursor cursor, QTextCharFormat format are in the right position  where i have my QTextObject
  
  bool isChecked  = format.property(CheckBox::CB_IsChecked).toBool();   
  isChecked = !isChecked;
  format.setProperty(CheckBox::CB_IsChecked,QVariant(isChecked));
  cursor.beginEditBlock();
  cursor.mergeCharFormat(format); //for some reason this don't work
  cursor.cursor.setCharFormat(format); // also this don't work  
  //  when painting the QTextObjectInterface  read always the same value from   format.property(CheckBox::CB_IsChecked).toBool();   
// even if it was changed by  above code.  
cursor.endEditBlock();

To copy to clipboard, switch view to plain text mode 

Is this the proper manner to do such thing ?
