Start by reading these:

Some more help if you need:

Assume you have a PowerPoint document at C:\Temp\Test.ppt, then create a vanilla (empty) widgets app.
In the .pro file, in the QT += ... line, insert axcontainer at the end.
In the designer, add a QAxWidget widget to your MainWindow,
In the mainwindow.cpp file, insert this line after ui->setup(this);

ui->axWidget->setControl("C:\\Temp\\Test.ppt");

That should show you the first page of your PowerPoint doc.

Oh Thanks I sucess it. and I have a one more question. Can i edit pptx file on QAxwidget? and after edit How to save pptx file in QAxwidget?

Hi sure you can edit the .pptx file directly.
However since there's no menu bar visible, there's no easy way to save the file.

One workaround is to add a Push Button to the form, right-click on the button and select "Go to slot" and click Ok, then you will have a new function void MainWindow::on_pushButton_clicked() in your mainwindow.cpp.
Then edit the function so it looks like this:

void MainWindow::on_pushButton_clicked()
{
    auto app = ui->axWidget->querySubObject("Application");
    auto acp = app->querySubObject("ActivePresentation");
    acp->dynamicCall("SaveAs(QString&)","C:\\Temp\\Test.ppt");
}

So when you want to save, click the button.
