Menu with "Empty Menu" Message in SC8

[acarur01]

I'd like to be able to use the menu button which does not contain embedded menus. I have the following code below but the problem is it still shows an empty menu below. How do I suppress this? The JS code works fine in SC7.

isc.Menu.create({
    ID: "menu",
    autoDraw: false,
    showShadow: true,
    shadowDepth: 10
});

isc.MenuButton.create({
    ID: "menuButton",
    title: "File",
    width: 100,
    menu: menu,
   click: function(){isc.warn('click');}

});

Probably best to simply not assign the menu to the MenuButoon if it has no items and you don't want to see the empty menu placeholder.

I have tried this, but I get an NPE in IE8 in ISC_Grid.js

$36d:function(_1){_1.autoDraw=false;var _2=this.menuConstructor

We need this resolved ASAP to move to SC8 please. Thanks.

I don't see this in my testing. Can you pick up the latest nightly and retry?

[acarur01]

Sure I'll let you know.

I've tried the same scenario with the build SmartClient_SC_SNAPSHOT-2010-05-18 and the NPE still occurs. Do you have Developer Tools in IE on debug mode? Note that I also only get the error when my warn message is on the screen. Once I click ok the error on the browser disappears.

[acarur01]

I've also tried with the following example:

isc.Label.create({ID: "testLabel", contents: "test"});

isc.MenuButton.create({
    ID: "menuButton",
    title: "File",
    width: 100,
click: function(){testLabel.setContents("TEST");}
});

With this example, the JS error in IE shows all the time whereas the above example only shows the JS error when the warning dialog is present.

I am unable to reproduce this with either example. How are you testing these samples? Are you copying this into a feature explorer sample? If not, what additional code is involved?

[acarur01]

I'm testing it with Feature Explorer. That's the only code I have. In fact, that's just a modified version of the demo in Control->Menus->Appearance.

I am using IE8 if that makes any difference.

[davidj6]

I was able to track down the issue and the fix should be available in the nightly tomorrow. In your use case do you want the down arrow to show?

[acarur01]

No. If there are no submenus the down arrow is pointless.

Do you by any chance know if there is a list of changes I can look at for each build?

[davidj6]

I'm not aware of a change list with the builds.

[acarur01]

I just ran the latest build..still the same problem.

I have another case in which I have a second level menu with data. This menu data is dynamically manipulated depending on the current state (whether to show part of the data or not). In some cases, I have an empty data array. If you run the example, this will show "Empty menu". I need a way to suppress this. Unfortunately, temporarily override the click method to do nothing does not work if there is an empty data list set on the menu.

isc.MenuButton.create({ID:"MenuItem",
canFocus:true,
title:" Visibility Test",
showDown:false,
showFocused:false,
showEmptyMessage:false,
showRollOver:false,
autoFit:true,
baseStyle:"CwMEIDef",
align:"bottom",
showMenuButtonImage:false,
menu:isc.Menu.create({ID:"MenuItem$menu",
fastCellUpdates:false,
canFocus:true,
title:"Visibility Test ",
showDown:false,
data:
[{title:"Visible",ID:"MenuItem1"},
{title:"Menu",submenu:isc.Menu.create({ID:"MenuItem2",fastCellUpdates:false,ID:"MenuItem2",data:[]})}
]})});
