building custom Gladevcp Widgets for linuxcnc

I thought this might go hand in hand with building GUIs
wiki.linuxcnc.org/cgi-bin/wiki.pl?GladeVCP_Custom_Widgets

Gee I think we need to make a separate developers manual for GladeVCP and GUI screens...

Chris M

thanks for sharing this looks nice and usefull

Chris,

I think this should go into the manual - for now, in the GladeVCP section

let's talk how to arrange it - it would be a pity if this important piece would be left out

- Michael

Yes in the manual probably would be good. eventually its probably more developer or advanced integrator..
More then anything I hope that if a user builds a useful widget they wake it glade widget so everyone can use it.

Michael you did work with gladevcp - There is a lot of good stuff there that could be reused if it only had some documentation or comments.
eg hal_glib and how to use the base widgets stiff.
for example I want to add linuxcnc stat stuff to my tooledit widget. I think I could actually get what I need from an action_base or EMC_STAT but can't figure it out. any hints.....

It would also help as I am tinkering with QTvcp ......

Well we can make that widget thing into an own section; you're right, the current GladeVCP manual already is a bit top-heavy

wrt: hal_glib and base widgets: this is Pavel's code and it is generally above my paygrade.. but maybe we can massage Pavel to jot down a few notes on which documentation for mere mortals can be based (that was my modus operandi

Big John If I added the custom widget stuff to the manual, where would you want it?
I'm kinda thinking it belongs in the developers manual under some VCP/GUI heading...
Ideas?

Hi Chris

It would also help as I am tinkering with QTvcp

Out of interest, are you talking about the Qt python bindings or the main C++ libs?

Reason I ask is that I am just finishing writing a Qt specific C++ library class, which abstracts most of the HAL and NML commands.
I can then include an instance of the class in another and get access to all the Linuxcnc internals.

I have built simple VCPs in Qt Designer then initiated them though a minor QMainWindow inheritance, created hal pins etc and linked the VCP buttons to a running sim instance of Linuxcnc.

The main problem is not being able to do things, it could be used to write an entire GUI to replace Axis if required, but making it so that others could use it.
I anticipate requiring to write a scripting tool beyond even the old Qt3 uic tool, which will create the source code from the ui in its entirety, before the average user would find
it usable.

But it keeps me off the streets and I have learnt a lot about Linuxcnc internals
