Hi.

I have a problem about Qtscript.

My project is a com port tool and my idea is: The main project loads a script file and returns commands to the C++ code, then the commands from script file are sent to the peripheral equipment. In this way I just need to change the script file if I want to send different commands each time.

Now I did in this way:
this is the C++ code to interpret script file:
Qt Code: 
  1. QScriptEngine engine; 
  2. QString scriptFileName(":/myscriptfile.js");// Change the script file according to the requirement. 
  3. QFile file(scriptFileName); 
  4. file.open(QIODevice::ReadOnly); 
  5. engine.evaluate(file.readAll(), scriptFileName); 
  6. file.close(); 
  7. QScriptValue global = engine.globalObject(); 
  8. QScriptValue GeneralCommand = global.property("myCommand"); 
  9. QScriptValue ATCommand1 = global.property("Command1"); 
  10. QScriptValue ATCommand2 = global.property("Command2"); 
  11. QScriptValue ATCommand3 = global.property("Command3"); 
  12. QScriptValue ATCommand4 = global.property("Command4"); 
  13. QScriptValue ATCommand5 = global.property("Command5"); 
  14.  
  15. CommandString[0]=GeneralCommand.call(ATCommand1).toString(); 
  16. CommandString[1]=GeneralCommand.call(ATCommand2).toString(); 
  17. CommandString[2]=GeneralCommand.call(ATCommand3).toString(); 
  18. CommandString[3]=GeneralCommand.call(ATCommand4).toString(); 
  19. CommandString[4]=GeneralCommand.call(ATCommand5).toString();

this is the script file"myscriptfile.js":
Qt Code: 
  1. //! [0] 
  2. function myCommand() { return this.Command;} 
  3. Command1 = { Command: 'test command 1'} 
  4. Command2 = { Command: ' test command 2'} 
  5. Command3 = { Command: ' test command 3} 
  6. Command4 = { Command: ' test command 4'} 
  7. Command5 = { Command: ' test command 5'}
  8. //! [0]
To copy to clipboard, switch view to plain text mode 

Actually it works. However I want to do it in a better way. the script file can be like this:
Qt Code: 
  1. SendCommand('test command 1'); 
  2. SendCommand('test command 2'); 
  3. SendCommand('test command 3'); 
  4. SendCommand('test command 4');
To copy to clipboard, switch view to plain text mode 
It is simple and easy to understand. But I don't know how to configure script engine in order to write script code like this? Is there someone can tell me how to do? thanks a lot.
