<section id="GUID-5FB87906-A38C-4BAB-92B3-75FF497E9E24"><title>Description</title> <p>The <filepath>txtu</filepath> project demonstrates a User Interface

MTM. The central class is <codeph>CTextMtmUi</codeph>, derived from

the User Interface MTM base class <codeph>CBaseMtmUi</codeph>. </p> <p>Note that the <filepath>txtu</filepath> project has dependencies

on some GUI components that might not be present on all SDKs. </p> <p> <filepath>txtu</filepath> implements the following MTM functionality: </p> </section>

<section id="GUID-8F7FD0AC-86BE-486B-B999-43EC6914A457"><title>Basic

functions for messages</title> <p> <codeph>Create()</codeph>: this

creates a new local message in the <systemoutput>Draft</systemoutput> folder, with description field set to "New Text", and then invokes

edit. </p> <p> <codeph>Edit()</codeph>: no UI for editing and viewing

text messages is implemented. A simple stub is provided that simply

appends the text "Edited document" to the message and puts up an information

message. </p> <p>If an edit command is invoked on a remote message

entry (an entry under a Text service entry), the MTM offers to copy

it to the local Inbox first. This is performed by class <codeph>CEditRemoteOperation</codeph>. and dialog resource <codeph>r_dialog_refuse_edit_remote_message</codeph>. </p> <p> <codeph>Open()</codeph> and <codeph>View()</codeph>: these

functions for a message context simply calls the edit function. </p> <p> <codeph>CopyToL()</codeph>, <codeph>MoveToL()</codeph>, <codeph>CopyFromL()</codeph>, <codeph>MoveFromL()</codeph> and <codeph>DeleteL()</codeph>: simple implementations of these functions are provided that use

the <codeph>CMsvEntry</codeph> copy, move and delete functions. These

commands are passed to the Message Server, which then passes them

on to the Server-side Text MTM. </p> <p> <codeph>ReplyL()</codeph> and <codeph>ForwardL()</codeph>: there is no UI support for message

replies and forwarding. </p> </section>

<section id="GUID-F1566C1D-A866-46F1-AE7B-34280C7A6FBB"><title>Basic

functions for services</title> <p> <codeph>Create()</codeph> and <codeph>Edit()</codeph>: when requested to create a new Text service entry,

a dialog pops up allowing the user to specify the folder associated

with the service. This is performed by class <codeph>CTextMtmEditServiceDialog</codeph> and resource <codeph>r_dialog_service_settings</codeph>. The service

entry can then be edited later on, to change the folder. </p> <p>After

the service entry is created or changed, an automatic refresh will

be triggered. </p> </section>

<section id="GUID-1084490D-DA56-4F06-BCA2-BD4698CE633E"><title>MTM-specific

operations</title> <p>The following MTM-specific operations are accepted: </p> <ul>

<li id="GUID-94BF89D8-80D9-53CD-B3C3-40150B16EF6A"><p>Refresh: this

command refreshes the currently highlighted service entry. It calls

the MTM-specific operations provided by the Client-side MTM to do

this. </p> </li>

<li id="GUID-65E9CE09-3968-5CA0-90E4-5421B608080C"><p>Export text

to file: exports the text contained in a text message to a file. This

is performed by <codeph>DoExportTextFromMessageL()</codeph>. </p> </li>
