marking active menu items
Locked
 
|
I need to create a menu in which the selectable items (MenuItemMorphs)
are sometimes active and sometimes inactive. For inactive items nothing is done when they are selected from the menu. Currently, I plan to indicate the difference by using a line (MenuLineMorph) to separate the items into two groups with the active items above. I consider this to be a poor solution for various reasons. I wonder if anyone can propose a better solution and preverably a more standard solution to this problem. The simpler and more portable the solution the better. Currently, I am using Squeak 3.6. I will soon be porting to 3.7 so I can use a Squeak 3.7 solution. Porting to 3.8 has been delayed because displaying a method in the debugger displays the wrong text in a method. The displayed text is off by one character for each assignment operator preceding the displayed text. (The displayed text is the text of the current message send in the method) I am using the Linux version of Squeak. Thanks Ralph Boland |

To mark items on a menu in a disabled state this is what I use:
(not tested) | menu | menu := MenuMorph new. menu add: aTitle target: anObject selector: aSelector menu lastItem isEnabled: false the #isEnabled: method is the one used when you type into a menu and some items gets temporarily disabled. Note that because of this, if you type into a menu and then delete the typing everything will get reenabled, even your manually disabled items, thus this isn't a perfect solution either (But I doubt that there is one, short of modifying MenuMorph and/or MenuItemMorph to support this kind of usage). BTW, you can disable the preference that gives keyboard focus to menus. Look into the preference panel for it.

So I take it you are not interested in only showing
active items.. As far as I know, MenuItemMorphs don't have a 'enabled' boolean but you could probably subclass MenuItemMorph to add it.. Re: 3.8 debugger display issue.. I noticed an issue in the debugger too related to the code it *hightlights*, but only when Shout was enabled. If Shout is disabled in the Preferences (sorry can't try it now myself, not at a Squeak computer) is it still a problem? - Chris > Message: 28 > Date: Wed, 18 Jan 2006 19:22:06 -0500 > From: Ralph Boland <[hidden email]> > Subject: marking active menu items > To: [hidden email] > Message-ID: > <[hidden email]> > Content-Type: text/plain; charset="iso-8859-1" > > I need to create a menu in which the selectable > items (MenuItemMorphs) > are sometimes active and sometimes inactive. > For inactive items nothing is done when they are > selected from the menu. > > Currently, I plan to indicate the difference by > using a line (MenuLineMorph) > > to separate the items into two groups with the > active items above. > I consider this to be a poor solution for various > reasons.

If you do what chris suggested it may be worth to do it in the MenuItemMorph itself and send it to the morphic team so that it gets added to morphic I think that this is a good functionality and we could avoid having subclass proliferation. We are trying to see with lukas how to add icons to list items. This is a feature that would make the browsers giving a lot more information. Stef |

But may be it is already possible. I can try to help if needed. Hilaire |
