set_ColumnCount()

TextFrameFormat::set_ColumnCount(int32_t) method

Sets number of columns in the text area. This value must be a positive number. Otherwise, the value will be set to zero. Value 0 means undefined value. Write int32_t.

void Aspose::Slides::TextFrameFormat::set_ColumnCount(int32_t value) override

Remarks

The following sample code shows how to add column in Text frame inside a PowerPoint Presentation.

System::String outPptxFileName = u"ColumnsTest.pptx";

auto pres = System::MakeObject<Presentation>();

auto shape1 = pres->get_Slides()->idx_get(0)->get_Shapes()->AddAutoShape(Aspose::Slides::ShapeType::Rectangle, 100.0f, 100.0f, 300.0f, 300.0f);
auto format = System::ExplicitCast<Aspose::Slides::TextFrameFormat>(shape1->get_TextFrame()->get_TextFrameFormat());
format->set_ColumnCount(2);
shape1->get_TextFrame()->set_Text(System::String(u"All these columns are forced to stay within a single text container -- ") + u"you can add or delete text - and the new or remaining text automatically adjusts " + u"itself to stay within the container. You cannot have text spill over from one container " + u"to other, though -- because PowerPoint's column options for text are limited!");
pres->Save(outPptxFileName, Aspose::Slides::Export::SaveFormat::Pptx);


{
    auto test = System::MakeObject<Presentation>(outPptxFileName);
    assert(2 == (System::ExplicitCast<Aspose::Slides::AutoShape>(test->get_Slides()->idx_get(0)->get_Shapes()->idx_get(0)))->get_TextFrame()->get_TextFrameFormat()->get_ColumnCount());
    assert(std::numeric_limits<double>::quiet_NaN() == (System::ExplicitCast<Aspose::Slides::AutoShape>(test->get_Slides()->idx_get(0)->get_Shapes()->idx_get(0)))->get_TextFrame()->get_TextFrameFormat()->get_ColumnSpacing());
}

format->set_ColumnSpacing(20);
pres->Save(outPptxFileName, SaveFormat::Pptx);

{
    auto test = System::MakeObject<Presentation>(outPptxFileName);
    assert(2 == (System::ExplicitCast<Aspose::Slides::AutoShape>(test->get_Slides()->idx_get(0)->get_Shapes()->idx_get(0)))->get_TextFrame()->get_TextFrameFormat()->get_ColumnCount());
    assert(20 == (System::ExplicitCast<Aspose::Slides::AutoShape>(test->get_Slides()->idx_get(0)->get_Shapes()->idx_get(0)))->get_TextFrame()->get_TextFrameFormat()->get_ColumnSpacing());
}

format->set_ColumnCount(3);
format->set_ColumnSpacing(15);
pres->Save(outPptxFileName, SaveFormat::Pptx);

{
    auto test = System::MakeObject<Presentation>(outPptxFileName);
    assert(3 == (System::ExplicitCast<Aspose::Slides::AutoShape>(test->get_Slides()->idx_get(0)->get_Shapes()->idx_get(0)))->get_TextFrame()->get_TextFrameFormat()->get_ColumnCount());
