Re: Handling lots of menu entries

No, you can do that all from the form designer.  Just use the same method
name for the DoubleClick event for each MenuItem.  The designer is smart
enough to know that the function already exists, so it'll use the same
function for each menu item.

Subject: Re: [DOTNET-WINFORMS] Handling lots of menu entries

How would this work if I am using the Forms Designer (aka Dialog Editor)? I
would create my 10 menu itmes and for a single menu item double click on to
create an event for just that menu entry and go back and edit the other to
add the same event to the other menu entries using the overloaded "+="?

Where would I do this? In the constructor for the Form?
If I edit the InitializeComponent funciton generated by the Dialog editor,
do I also have to edit that .resX file whose format I don't understand? The
InitializeComponent function seems the logical place to do it (if it does
not crash that dialog editor).

Ok, so what do I do in the event hander? Would it look like this?

MenuItem * pMI = (MenuItem*)sender;
if(pMI == miOpacity100) Opacity = 1.0;
else if (pMI == miOpacity90) Opacity=.9; else if (pMI == miOpacity80)
Opacity=.8; ...

Ugghhh! What do you think? Is that a significant improvement over having a
seperate event handler for each menu item? Is there a better way?
