I just started with envisage framework. In the 4.x version I saw a few example, but I need a good documentation: link.
How can I add custom buttons to the envisage workbench, or h开发者_C百科ow can I create a similar one?
The best place look for documentation is the Acmelab example in the Envisage source tree.
I'm assuming when you talk about custom buttons you mean buttons on a toolbar. First you need to create a WorkbenchActionSet, add your toolbar there, and then define your actions and assign them a button image. Here is the (slightly modified) Acmelab example with non-relevant parts taken out:
test_action_set.py
# Enthought library imports.
from envisage.ui.action.api import Action, Group, Menu, ToolBar
from envisage.ui.workbench.api import WorkbenchActionSet
class TestActionSet(WorkbenchActionSet):
""" An action test useful for testing. """
#### 'ActionSet' interface ################################################
tool_bars = [
ToolBar(name='Fred', groups=['AToolBarGroup']),
ToolBar(name='Wilma'),
ToolBar(name='Barney')
]
actions = [
Action(
path='ToolBar',
class_name='acme.workbench.action.new_view_action:NewViewAction'
),]
new_view_action.py
""" An action that dynamically creates and adds a view. """
# Enthought library imports.
from pyface.api import ImageResource
from pyface.action.api import Action
from pyface.workbench.api import View
class NewViewAction(Action):
""" An action that dynamically creates and adds a view. """
#### 'Action' interface ###################################################
# A longer description of the action.
description = 'Create and add a new view'
# The action's name (displayed on menus/tool bar tools etc).
name = 'New View'
# A short description of the action used for tooltip text etc.
tooltip = 'Create and add a new view'
image = ImageResource(Your Image File Name Goes Here)
###########################################################################
# 'Action' interface.
###########################################################################
def perform(self, event):
""" Perform the action. """
# You can give the view a position... (it default to 'left')...
view = View(id='my.view.fred', name='Fred', position='right')
self.window.add_view(view)
# or you can specify it on the call to 'add_view'...
view = View(id='my.view.wilma', name='Wilma')
self.window.add_view(view, position='top')
return
#### EOF ######################################################################
