Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
I was trying to create a message box/dialog box that pops up when an option is selected. The message box should allow the user select 'Ok' to proceed to a form and 'Cancel' to quit the process. I tried with tkMeassageBox but I kept getting this error 'No protocol specified TclError: couldn't connect display ":0"'.
So, I thought it might be that Tkinter doesn't work well with openerp. Is there a way to go about achieving this?
Thanks in advance
@Med, but how do I incorporate the javascript in openerp?
I changed from workflow to object.
Tell us what you exactly want to do with this button.
I am working on the HR Leave Module(hr_holidays). Based on the requirements i am working with, when a user puts in a leave request, At the point of selecting a leave type e.g. 'Annual Leave', the system should do a check if the user has allocated leave days left. If user doesn't have any allocated days left, a pop-up should be displayed with a message informing the user to either apply for extra allocation or abort the process. If user clicks on 'Ok' it should redirect the user to the allocation request form but if the user clicks on 'cancel' it should exit the process of leave request. So thats why i need to put up a message box. Thanks
For the case of 'type=object', you need to add a button in your .xml file (this is easy to do), the second step is to write a function in python to handle the action needed when clicking this button (this is the hard part !).
I will extend my answer later.
Use Javascript rather than Python.

(Answer modified after comment).
In OpenERP you can create 3 types of Buttons (related to the Button's type attribute):
1_ Type object
2_ Type workflow
3_ Type action

I think in your case you are dealing with the type="workflow".
To watch attentively: Workflow add button Customize workflows in Odoo
The best at last (but in French - an example for HR_Leave workflow modification): http://laboiteatice.fr/ecotice/diapo/co/modifier_processus.html?mode=html
WARNING:
When customizing a workflow, be sure you do not modify an existing node or arrow, but rather add new nodes or arrows. If you absolutly need to modify a node or arrow, you can only change fields that are empty or set to the default value. If you don't do that, your customization will be overwrited at the next update or upgrade to a future version of OpenERP.
