22 This module is imported from C++ SalomeApp_Application and initialized
23 (call to initialize function with 4 parameters)
24 module : 0 if it is plugins manager at the application level, 1 if it is at the module level
25 name : the name of the plugins manager. This name is used to build the name of the plugins files
26 basemenuname : the name of the menu into we want to add the menu of the plugins ("Tools" for example)
27 menuname : the name of plugins menu
29 A plugins manager is created when calling initialize.
31 The plugins manager creates a submenu <menuname> in the <basemenuname>
34 The plugins manager searches in $HOME/.config/salome/Plugins,
35 $HOME/$APPLI/Plugins, $SALOME_PLUGINS_PATH directories files named
36 <name>_plugins.py and executes them.
38 These files should contain python code that register functions into
41 Example of a plugins manager with name salome. It searches files with
42 name salome_plugins.py (example follows)::
44 import salome_pluginsmanager
47 from qtsalome import QMessageBox
48 QMessageBox.about(None, "About SALOME pluginmanager", "SALOME plugins manager in SALOME virtual application ")
50 salome_pluginsmanager.AddFunction('About plugins','About SALOME pluginmanager',about)
52 All entries in menu are added in the same order as the calls to
53 AddFunction. It is possible to customize this presentation by getting
54 the entries list (salome_pluginsmanager.entries()) and modifying it in
55 place. For example, you can do that :
56 salome_pluginsmanager.entries().sort() to order them alphabetically or
57 salome_pluginsmanager.entries().remove("a") to remove the entry named "a".
59 It is possible to put entries in submenus. You only need to give a
60 name with / to the entry. for example::
62 salome_pluginsmanager.AddFunction('a/b/About','About SALOME pluginmanager',about)
64 will add 2 submenus a and b before creating the entry.
66 In short to add a plugin:
68 1. import the python module salome_pluginsmanager (in your
69 salome_plugins.py or <module>_plugins.py)
71 2. write a function with one argument context (it's an object with 3
74 3. register the function with a call to AddFunction (entry in menu plugins,
79 - sg : the SALOME Swig interface
80 - study : the SALOME study object that must be used to execute the plugin
