Few questions about hal and pyvcp

[wygrac]

Hi

I'm quite new in this subject but to cut the small talk, here are my three problems/questions.

1. I'm building my own panel using pyvcp, got most off it running but have at the moment one problem - Is it possible and if is how to do it to add a second dialog window under one off the buttons. Meaning for example can I add a button in my panel that when pressed will pop out a halmeter?

2. Can I add some C programming to hal programming?

3. I have wrote a short hal file in which there are few commands with loadrt, addf, nets and so on. Everything is ok but i have a problem with adding in my file a comand to start up pyvcp meaning:
loadusr pyvcp -c nameforpanel nameofffile.xml
When i load the hal file this command is loaded last even that its in the middle of the file and all the nets dont work couse program tries to load them first and then nameofffile.xml. Any ideas how to fix this?

Thank You for any comments.

For your third question add -W (capital w) to the loadusr command.
This makes HAL wait till pyvcp is finished before running the rest of the commands.
look in the man pages under halcmd for other options such as -Wn which waits for a panel to be closed before ending a HAL session.

second question : If you mean mix HAL commands and C programming - no but you could change the HAL c source code to get other commands

First question : I'm sure there is a way to do this but it won't be straight forward. Are you using this pyvcp panel with EMC or on it's own?

1. First question - pyvcp own panel not with emc.
