Updated for significant performance improvement.
Verified to work with WebOS 1.2 and 1.2.1
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:
Code:
sudo vi /usr/palm/applications/com.palm.app.email/app/controllers/list-assistant.js
Find the setup function and modify the cmdMenuModel items, replace the
with
Code:
{label:$L('Delete All'), icon:'delete', command:'deleteall'},
Find the handleCommand function and add the following case statement:
Code:
case 'deleteall':
this.handleDeleteAll();
break;
Now add the following three functions:
Code:
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 i;
//Since the list is loaded dynamically we may have the count of all emails but not all of the data
//So start with count and work backward with error handling
//When reach 0 trigger at least one more pass after data has had a chance to refresh
for(i=count-1; i>=0; i--)
{
var item = this.emailListElement.mojo.getNodeByIndex(i);
if(item !== undefined)
{
id = item.id;
if(id)
{
if(i==0)
{
this.controller.serviceRequest(Email.identifier, {
method: 'setDeleted',
parameters: {'message':id, 'value': true },
onSuccess: this.handleDeleteAllResponse.bind(this),
onFailure: this.handleDeleteAllResponse.bind(this)
});
}
else
{
this.controller.serviceRequest(Email.identifier, {
method: 'setDeleted',
parameters: {'message':id, 'value': true },
onSuccess: undefined,
onFailure: undefined
});
}
}//if(id)
}//if item !== undefined
else
{
if(i==0)
{
//item was undefined probably because it is currently marked for delete
this.deleteAll();
}
}
}//for
}//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 delete all ') + "<b>" + totalCount + "</b>" + $L(' items in this folder?'),
choices: [
{label:$L('Yes'), value:'yes', type:'affirmative'},
{label:$L('No'), value:'no', type:'alert'}
]
});
},
