I can't control menu state in Python

[goshawk]

Hi there

I'm writing add-in code for EA 4.50.744 (Unicode) in Python.

I want to control the menu state (selectable or not) by EA_GetMenuState, but I can't.
# I attach my code at the end of this mail

In this code, I define 1 parent menu "AAA" and 2 child  menus "BBB", "CCC". I expect that menu "AAA" and "BBB" are selectable, "CCC" is not.

But, all the menus are selectable. Why?

Is there any example that control menu state in Python?

Maybe because MenuLocation can take only "TreeView" and "Diagram"? I never came across "MainMenu"

[Aaron B]

"MainMenu" is indeed a valid location.
My only initial thought is to make sure your indentation/logic is correct.  It is a bit hard to tell from your pasted sample as the spacing seems to be out.

Just to try a different logic flow, perhaps try this:

Code: [Select]

elif MenuLocation == "MainMenu":
 IsEnabled = True
 if MenuName == u'-&AAA' and ItemName == u'&CCC':
   IsEnabled = False

Should result in all menu items except "CCC" being enabled.

Sorry, I should use a tag for code.

Just to try a different logic flow, perhaps try this:
Code:

elif MenuLocation == "MainMenu":
  IsEnabled = True
  if MenuName == u'-&AAA' and ItemName == u'&CCC':
    IsEnabled = False

I modified code as follows,

Code: [Select]

     print "Usage: testplugin.py [--register|--unregister]"

I can't control indentation.

Should result in all menu items except "CCC" being enabled.

I tried modified code, but still all the menu were selectable.
Then got debug print messages as follows,

Code: [Select]


-&AAA &BBB True
-&AAA &CCC False
-&AAA &BBB True
-&AAA &CCC False
-&AAA &BBB True
-&AAA &CCC False
-&AAA &BBB True
-&AAA &CCC False
-&AAA &BBB True
-&AAA &CCC False
...


valiable IsEnabled was actually set "False", but menu "CCC" was still selectable.

Did anyone control menu state in Python?

Thank you.

[thomaskilian]

Okay. So my suggestion would be to reduce the example to a single entry and trying to toggle that on/off. Having that working it should be possible to crawl back to your original code

Hi  thomaskilian

Thanks for your advice.
I minimized my code. It has only one menu "AAA".
Then menu "AAA" will be always unselectable(IsEnabled = False).

Code: [Select]

I tried above code, but the menu "AAA" is selectable.
So, debug print is as follows,

Code: [Select]


&AAA False
&AAA False
&AAA False
...
&AAA False
&AAA False
&AAA False
No choice


Sigh... :-/

I now tried this with Perl and - no matter what I set isSelected or isEnabled - the entries always appear and are selectable. Looks like a bug. I didn't come across since I simply included menu items or left them out. That still is okay for me, but EA_GetMenuState doesn't seem to work correctly.

[Eve]

EA_GetMenuState seems to work for me, but I'm not using Python (or Perl).  The possibility that occurs to me is that maybe you haven't declared your functions to have those parameters passed by reference.

I had a bit of a look for how to do this in python and came up with the following page.  Hope it helps http://mail.python.org/pipermail/python-win32/2002-November/000590.html

Hello simonm
Thank you for your importtant advice.

I had a bit of a look for how to do this in python and came up with the following page.  Hope it helps http://mail.python.org/pipermail/python-win32/2002-November/000590.html

I refered that webpage. That's it.
I added code "return 0, IsEnabled, IsChecked" to method EA_GetMenuState for reference values.

Code: [Select]

I could control the menu state.
In this code, the menu "AAA" is unselectable. I got it!

Thank youf so much, everyone.

[thomaskilian]

Unfortunately there is no such construct for Perl So one can't actually make use of that feature. By default Perl->Perl uses always by-reference, but the COM interface seems to behave somewhat different.

Hi there, I have a problem again.

I could control the menu state.
In this code, the menu "AAA" is unselectable. I got it!

I added two more sub menus "BBB", "CCC" to EA_GetMenuItems.

I also added the method "SomeMethod" and call in EA_MenuClick at the menu "BBB".

Code: [Select]


...
   # Menu items
   def EA_GetMenuItems(self, Repository, MenuLocation, MenuName):
       if MenuName == "":
           menu = [
               u'-AAA',                ]
       elif MenuName == u'-AAA':
           menu = [
               u'BBB',
               u'CCC',
               ]
       else:
           menu = ""
       return menu

   # Menu state control
   def EA_GetMenuState(self, Repository, MenuLocation, MenuName,
                       ItemName, IsEnabled, IsChecked):
       ##   print "EA_GetMenuState"
       if MenuLocation == "TreeView":
           IsEnabled = False
       elif MenuLocation == "Diagram":
           IsEnabled = False
       elif  MenuLocation == "MainMenu":
           IsEnabled = True
           if (MenuName == u'-AAA') and (ItemName == u'BBB'):
               IsEnabled = True
           elif (MenuName == u'-AAA') and (ItemName == u'CCC'):
               IsEnabled = False
       print MenuName, ItemName, IsEnabled
       return 0, IsEnabled, IsChecked

   def EA_MenuClick(self, Repository, MenuLocation, MenuName, ItemName):
       print "EA_MenuClick"
       if MenuLocation == "TreeView":
           pass
       elif MenuLocation == "Diagram":
           pass
       elif  MenuLocation == "MainMenu":
           if (MenuName == u'-AAA') and (ItemName == u'BBB'):
               print "Selected", MenuName, ItemName
               self.SomeMethod()
           elif (MenuName == u'-AAA') and (ItemName == u'CCC'):
               print "Selected", MenuName, ItemName
       return 0

   def SomeMethod(self):
       print "Do something"

I executed this code form EA. Then I got the debug print as follows,

Code: [Select]

-AAA BBB True
-AAA CCC False
-AAA BBB True
-AAA CCC False
...
-AAA CCC False
-AAA BBB True
-AAA BBB True
EA_MenuClick
Selected -AAA BBB
Do something


I could executed the method "SomeMethod" as I expected.

Next, I added one more menu "DDD". This menu is not a sub menu as "BBB" and "CCC".

Code: [Select]


   def EA_GetMenuItems(self, Repository, MenuLocation, MenuName):
       if MenuName == "":
           menu = [
               u'-AAA',
               u'DDD',
               ]
       elif MenuName == u'-AAA':
           menu = [
               u'BBB',
               u'CCC',
               ]
       else:
           menu = ""
       return menu

   # Menu state control
   def EA_GetMenuState(self, Repository, MenuLocation, MenuName,
                       ItemName, IsEnabled, IsChecked):
       ##   print "EA_GetMenuState"
       if MenuLocation == "TreeView":
           IsEnabled = False
       elif MenuLocation == "Diagram":
           IsEnabled = False
       elif  MenuLocation == "MainMenu":
           IsEnabled = True
           if (MenuName == u'-AAA') and (ItemName == u'BBB'):
               IsEnabled = True
           elif (MenuName == u'-AAA') and (ItemName == u'CCC'):
               IsEnabled = False
           elif ItemName == u'DDD':
               IsEnabled = False
       print MenuName, ItemName, IsEnabled
       return 0, IsEnabled, IsChecked

   def EA_MenuClick(self, Repository, MenuLocation, MenuName, ItemName):
       print "EA_MenuClick"
       if MenuLocation == "TreeView":
           pass
       elif MenuLocation == "Diagram":
           pass
       elif  MenuLocation == "MainMenu":
           if (MenuName == u'-AAA') and (ItemName == u'BBB'):
               print "Selected", MenuName, ItemName
               self.SomeMethod()
           elif (MenuName == u'-AAA') and (ItemName == u'CCC'):
               print "Selected", MenuName, ItemName
           elif ItemName == u'DDD':
               print "Selected", MenuName, ItemName
       return 0

So, I tried this code again.
But I couldn't execute the method "SomeMthod".
I got debug print as follows,

Code: [Select]


DDD False
DDD False
...
DDD False
DDD False
-AAA BBB True
-AAA CCC False
DDD False
-AAA BBB True
-AAA CCC False
DDD False
...
DDD False
-AAA BBB True
-AAA BBB False

Why is IsEnabled "False" when I chose the menu "BBB"?
Why can't I execute the method "SomeMethod"?
Is there any advice or suggestion?
thank you.
