Then I save this new Presentation to a PPT File.Until now all is OK.
But now I want to edit the "title text" of my "title slide" (the first slide)...Have I to edit the Master Template ? Slide ? Can you explain me how to do this ? (Find the title text and edit it)
You can change title text before saving a presentation or open saved presentation again and change title after that.
Title of a slide is a text of title placeholder.
How to change text you can find in the Developer Guide.
For example in the Change Text in a Placeholder article.
Also our demos have several code examples for that.
If slide doesn’t have TextHolder you can’t change title text but you can add rectangle
with text in any position of a slide. Please check this chapter.
After that you can add TextFrame to this rectangle and insert some text.
