Re: How to get started in GUI Programming?
If you come from visual basic, I suggest to use pythoncard GUI, which
is
very simple to develop with a Ressource Editor (create a panel, see
labwindows, visual basic ..).
https://sourceforge.net/projects/vb2py/
a package to transform VB to pythoncard
http://www.linux2000.com/pimp.html
a pythoncard application

Re: Output to a text window
Hi, http://spinecho.ifrance.com/frmouterr-py242-wxpy2621.zip I use this gui windows written by jean marie fauth, which is very easy: printing to stdout or stderr (gui windows written in wxpython). You have only to translate frmouterr in pygtk. ph DALET FRANCE On 17 fév, 01:19, [EMAIL PROTECTED] wrote: > Hi, > > I'm going around in circles so I'm asking for help.

Re: pySerial: write in a blocking mode
Hi I have developped a python script to control a rs232c rs485 converter, named pyRS485 with pythoncard on windows. ftp-champo.ac-toulouse.fr/pub/btseo/pdalet/python/ python 2.4 Electronics Applications 20050902.exe The best solution is to send the last character with interrupt. when the TDR is empty an interrupt is generated. An interrupt program is executed to change the state of dtr. Not evident on Windows and linux. I have used temporisation, with different values for a slow pc and speed pc.
