Handling Microsoft PowerPoint (file format)
This page discusses various available options for working with "Microsoft PowerPoint":http://en.wikipedia.org/wiki/Microsoft_PowerPoint#File_formats documents in your Qt application. Please also read the general considerations outlined on the Handling Document Formats page.

One needs to distinguish between two different formats (this page deals with both of them):
table{width:95%;margin-left:2.5%}.
| |. Legacy "PowerPoint Presentation" format |. "Office Open XML Presentation" format |
| classification: | binary | XML-based |
| main filename extension: | {font:1em monospace}.ppt | {font-family:monospace}.pptx |
| main internet media type: | {font:0.9em monospace}application/vnd.ms-powerpoint | {font:0.9em monospace}application/vnd.openxmlformats-officedocument.presentationml.presentation |
| native format of PowerPoint: | until PowerPoint 2003 | since PowerPoint 2007 |
Reading / Writing
Using PowerPoint itself
If you are exclusively targeting the Windows platform and Microsoft PowerPoint will be installed on all target machines, then you can use "Qt’s ActiveX framework":http://doc.qt.io/qt-4.8/activeqt.html to access PowerPoint’s .ppt and .pptx processing functionality through OLE automation. For an introductory code example (and a way to list the API provided by the PowerPoint COM object), consult "this how to":http://wiki.qt.io/Using_ActiveX_Object_in_QT (focuses on Microsoft Excel, but it works the same way for PowerPoint).
