What has been done

• Added basic functionalities of a text editor

  1. New File

     • Setting current text to an empty string

       ui->textEdit->setPlainText("");

  2. Open File

     • Asking for file name using dialog box

       QFileDialog::getOpenFileName(this,"Open a file");

     • Setting Global File name to selected file

       mFilename = file;
       // Taking all data into a in stream
       QTextStream in(&sFile);
       
       //Reading that data
       QString text = in.readAll();
       sFile.close();
       
       //Setting the read data to text
       ui->textEdit->setPlainText(text);

  3. Save

     • Setting out stream of file to save

       QTextStream out(&sFile);
       
       out << ui->textEdit->toPlainText();
       
       sFile.flush();
       sFile.close();

  4. Save As

     • Asking for a file name in a dialog box

       QString file = QFileDialog::getSaveFileName(this,"Open a file");

  5. Copy

     ui->textEdit->copy();

  6. Cut

     ui->textEdit->cut();

  7. Paste

     ui->textEdit->paste();

  8. Undo

     ui->textEdit->undo();

  9. Redo

     ui->textEdit->redo();

  10. Bold

      // Saving font weight in a local varaible
      int font = ui->textEdit->fontWeight();
      
      //First check if the font weight is not equal to the weight of BOLD
      if(font != QFont::Bold){
          // Then set the selected text to bold
      
          ui->textEdit->setFontWeight(QFont::Bold);
      }
      // If it is equal
      else{
          // If it is equal then set text to normal {UnBold feature}
          ui->textEdit->setFontWeight(QFont::Normal);
      }
      

  11. SubScript and SubScript

      //Added scripting to a local variable
      //And then setting that formatting with the current format
      auto isSubscript = ui->textEdit->currentCharFormat();
      
      // Will check whether the current format is subscript
      if(isSubscript.verticalAlignment() != QTextCharFormat::AlignSubScript){
          // no
          // turn current format to subscript
          QTextCharFormat format;
          format.setVerticalAlignment(QTextCharFormat::AlignSubScript);
          ui->textEdit->setCurrentCharFormat(format);
      }
      else{
          // yes
          // turn current format back to normal
          QTextCharFormat format;
          format.setVerticalAlignment(QTextCharFormat::AlignNormal);
          ui->textEdit->setCurrentCharFormat(format);
      }
      
      //----------------------------------------------------------------
      
      // Similar to subscript
      // Current format will change
      auto isSubscript = ui->textEdit->currentCharFormat();
      
      if(isSubscript.verticalAlignment() != QTextCharFormat::AlignSuperScript){
          QTextCharFormat format;
          format.setVerticalAlignment(QTextCharFormat::AlignSuperScript);
          ui->textEdit->setCurrentCharFormat(format);
      }
      else{
          QTextCharFormat format;
          format.setVerticalAlignment(QTextCharFormat::AlignNormal);
          ui->textEdit->setCurrentCharFormat(format);
      }

Issues / Challenges

• Issue 1 : Adding QPdfView library giving error of not finding the library.

• Issue 2 : Current format is changed while using Bold, SubScript, SuperScript, Selected text may not change because, setCurrentCharFormat is used rather than mergeCharFormat.

• Challenge 1 : Adding my Resume is bit challenging now but still finding a way to do that.
