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.
