Overview

This code snippet demonstrates how to launch an application based on a given document using the AppManager Platform Service for Web Runtime, introduced in S60 5th Edition. Image files were chosen to present the MIME type handling in WRT.

Source file: Relevant HTML components

<select size = "5" id = "imageList" onclick = "show();">
<option></option>
</select>

Source

/**
* Shows the selected image.
*/

function show() {
var so = null;
 
try {
//Getting service object for application management.
var so = device.getServiceObject("Service.AppManager", "IAppManager");
} catch (ex) {
alert("Exception in getting application service object: " + ex);
return;
}
 
var imageList = document.getElementById("imageList");
for (var i = 0; i < imageList.options.length; i++) {
if (imageList.options[i].selected) {
var criteria = new Object();
criteria.Document = new Object();
//Setting the path to file that must be opened in a standalone
//application
criteria.Document.DocumentPath = imageList.options[i].value;
//Opening the file in standalone application
try {
var res = so.IAppManager.LaunchDoc(criteria);
if (res.ErrorCode != 0){
alert(res.ErrorCode + ' ; ' + res.ErrorMessage);
}
} catch (ex){
alert("Exception in launching document: " + ex);
}
}
}
}

Postconditions

The image selected from the list is displayed in a standalone application.

Supplementary material

This code snippet is part of the stub concept, which means that it has been patched on top of a template application in order to be more useful to developers. The version of the WRT stub application used as a template in this snippet is v1.1.

  • The patched, executable application that can be used to test the features described in this snippet is available for download at Media:MimeTypeHandling.zip.
  • You can view all the changes that are required to implement the above-mentioned features. The changes are provided in unified diff and colour-coded diff (HTML) formats in Media:MimeTypeHandling.diff.zip.
  • For general information on applying the patch, see Using Diffs.
  • For unpatched stub applications, see Example stub.
