QSerialDevice enumerator deletion question

[kuzulis]

Upon completion of the application, the OS itself will remove all.
No need to call the destructor.

PS:
This version of the library is outdated.
Instead it use of version 2.0, as it will be included in Qt as a addon.
Already in progress preparatory work for the integration.

Hi,

I went to http://gitorious.org/qserialdevice and took a copy of the master branch. Isn't this the latest then ?

In my opinion, it is a rather 'dirty' programming practice to just let the OS clean up all the handles you left open... Especially in a cross-platform environment like Qt where not every OS may behave as expected. Maybe you could consider the Meyers approach for the singleton pattern.

Regards,
Marc

No, master branch is the old library to the old API, as with version 0.3 and 0.4.

The new branch 2.0 is completely different, has a different API, which is radically different from the old API.
The difference is in the name, count and functionality of its constituent classes,
as well as extensive support for new operating systems.

See simply wiki: http://gitorious.org/qserialdevice/pages/Home

I know it's dirty. But since memory is allocated only once - then the dirt is not so dirty.
The new library, this class of functional and removed. So do not worry.

Hi kuzulis,

Is the 2.0 branch fully functional ? I started a very simple 'terminal' like program, and it seems to me that the readyRead() signal is not always emitted.

I send a text command to a device, and it sends me about 20 lines of text. On the first readyRead(), about 6 lines are in the buffer and I read it all. There is no readyRead() signal for data arriving after this. When I send a new command, readyRead() fires again, and then I see the remaining data.

I have put a small example program in attachment. Only the com_data_available() and on_leCmd_returnPressed() functions are relevant. The .pro file will need to be adapted to include SerialPort on your computer. I'm using Windows.

Best regards,
Marc
