mousedown in the mac menubar

I am an experienced hypercard programmer, but very new to Revolution. I have nearly completed my first software project and am now experimenting with the standalone builder and the menu builder.

When I first moved my menu to the Mac menubar I found that my mousedown handlers in each button didn't work. A quick trip to the documentation revealed that I have to put the mousedown handlers in the group script. OK no big deal. I did it. It still doesn't work.

After a bit of investigation I discovered to my horror that "The Target" does not return the name of the menu button that is being activated, but rather the name of the menubar group.

Am I missing something here? Do I have to write a giant mousedown handler that deals with EVERY menu button each time ANY menu button is clicked?

Thanks, in advance, for your responses,
Grazer

Hi Grazer,

You probably want to read about the menuPick message in the docs.

Best,

Mark

I am using the menupick messages. The reason I also use mousedown handlers is to customize the menuitems (enable/disable, checkmarks) each time the user clicks on a menu.

Dear Grazer,

It works fine here. Could you post your script?

Best,

Mark

on mousedown -- in menubar group script
get the short name of the target
if it is "File" then
--enable and disable File menuitems
else if it is "Edit" then
--enable and disable Edit menuitems
end if
end mousedown

The problem, I think, is that "the target" does not return the name of a menu button.

Hi Grazer,

I understand you problem. Indeed, the target is not the menu item but the group.

Usually, I use a different approach. The enabled/disabled of menu items depends on particular conditions. I adjust the menus whenever these conditions change. Rather than a mouseDown handler in the group, I use my own menuUpdate script.

Your script might look like (theoretically):

Code: Select all

on mouseDown
  if the hilite of btn "Allow" then
    put "Cut/X" into line 3 of btn "Edit" of grp "Menubar 1"
  end if
end mouseDown

My script would look like:

Code: Select all

on menuUpdate
 if the hilite of btn "Allow" then
    put "Cut/X" into line 3 of btn "Edit" of grp "Menubar 1"
  end if
end menuUpdate

and the button "Allow" would contain a simple script:

Code: Select all

on mouseUp
  menuUpdate
end mouseUp

(These script are just to illistrate my approach, I don't claim they actually work).

Best regards,

Mark
