ForEach class

Represents a group of methods intended to iterate over different Presentation model objects. These methods can be useful if you need to iterate and change some Presentation’ elements formatting or content, e.g. change each portion formatting.

Typedefs

Typedef	Description

Remarks

auto presentation = System::MakeObject<Presentation>(u"pres.pptx");

auto lambda = [](SharedPtr<Portion> portion, SharedPtr<Paragraph> para, SharedPtr<BaseSlide> slide, int32_t index) -> void
{
    portion->get_PortionFormat()->set_LatinFont(System::MakeObject<FontData>(u"Times New Roman"));
};
auto callback = std::function<void(SharedPtr<Portion> portion, SharedPtr<Paragraph> para, SharedPtr<BaseSlide> slide, int32_t index)>(lambda);

ForEach::Portion(presentation, callback);

presentation->Save(u"pres-out.pptx", SaveFormat::Pptx);
