This will add a button at the bottom of the screen with a trashcan icon between the Compose and Refresh buttons. Selecting the button will delete all email items in the list after prompting the user for confirmation.

I am deliberately not using line numbers to minimize the need for updates as new WebOS releases come out.

Open:

<pre><nowiki>/usr/palm/applications/com.palm.app.email/app/controllers/list-assistant.js</nowiki></pre>

Find the setup function and modify the cmdMenuModel items, replace the

<pre><nowiki>{},</nowiki></pre>

with

<pre><nowiki>{label:$L('Delete All'), icon:'delete', command:'deleteall'},</nowiki></pre>

Find the handleCommand function and add the following case statement:

<pre><nowiki>
case 'deleteall':
this.handleDeleteAll();
break;
</nowiki></pre>

Now add the following three functions:

<pre><nowiki>
handleDeleteAllResponse: function (event) {
//check to see if there are more items to delete.
this.deleteAll();
},

deleteAll: function(){

var count = this.emailListElement.mojo.getLength();

var id;

if(count > 0)
{
var item = this.emailListElement.mojo.getNodeByIndex(0);

if(item !== undefined)
{
id = item.id;

if(id)
{
this.controller.serviceRequest(Email.identifier, {
method: 'setDeleted',
parameters: {'message':id, 'value': true },
onSuccess: this.handleDeleteAllResponse.bind(this),
onFailure: this.handleDeleteAllResponse.bind(this)
});
}//if(id)
}//if item !== undefined
else
{
//item was undefined probably because it is currently marked for delete
this.deleteAll();
}
}//count > 0
},

handleDeleteAll: function (event) {

var totalCount = 0;

totalCount = this.emailListElement.mojo.getLength();

this.controller.showAlertDialog({
onChoose: function(value) {
if(value == 'yes') {
//Delete all items in this folder
this.deleteAll();
}
},
title: '<b>' + $L('Delete All') + '</b>',
message: $L('Are you sure you want to delte all ') + "<b>" + totalCount + "</b>" + $L(' items in this folder?'),
choices: [
{label:$L('Yes'), value:'yes', type:'affirmative'},
{label:$L('No'), value:'no', type:'alert'}
]
});
},
</nowiki></pre>
