Aspose::Words::ConditionalStyleCollection::idx_get method

ConditionalStyleCollection::idx_get(Aspose::Words::ConditionalStyleType) method

Retrieves a ConditionalStyle object by conditional style type.

System::SharedPtr<Aspose::Words::ConditionalStyle> Aspose::Words::ConditionalStyleCollection::idx_get(Aspose::Words::ConditionalStyleType conditionalStyleType)

Examples

Shows how to work with certain area styles of a table.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);

SharedPtr<Table> table = builder->StartTable();
builder->InsertCell();
builder->Write(u"Cell 1");
builder->InsertCell();
builder->Write(u"Cell 2");
builder->EndRow();
builder->InsertCell();
builder->Write(u"Cell 3");
builder->InsertCell();
builder->Write(u"Cell 4");
builder->EndTable();

// Create a custom table style.
auto tableStyle = System::ExplicitCast<TableStyle>(doc->get_Styles()->Add(StyleType::Table, u"MyTableStyle1"));

// Conditional styles are formatting changes that affect only some of the table's cells
// based on a predicate, such as the cells being in the last row.
// Below are three ways of accessing a table style's conditional styles from the "ConditionalStyles" collection.
// 1 -  By style type:
tableStyle->get_ConditionalStyles()
    ->idx_get(ConditionalStyleType::FirstRow)
    ->get_Shading()
    ->set_BackgroundPatternColor(System::Drawing::Color::get_AliceBlue());

// 2 -  By index:
tableStyle->get_ConditionalStyles()->idx_get(0)->get_Borders()->set_Color(System::Drawing::Color::get_Black());
tableStyle->get_ConditionalStyles()->idx_get(0)->get_Borders()->set_LineStyle(LineStyle::DotDash);
ASSERT_EQ(ConditionalStyleType::FirstRow, tableStyle->get_ConditionalStyles()->idx_get(0)->get_Type());

// 3 -  As a property:
tableStyle->get_ConditionalStyles()->get_FirstRow()->get_ParagraphFormat()->set_Alignment(ParagraphAlignment::Center);

// Apply padding and text formatting to conditional styles.

        {

        }
    }
}

// Apply the custom style, which contains all conditional styles, to the table.
table->set_Style(tableStyle);

// Our style applies some conditional styles by default.
ASSERT_EQ(TableStyleOptions::FirstRow | TableStyleOptions::FirstColumn | TableStyleOptions::RowBands, table->get_StyleOptions());

// We will need to enable all other styles ourselves via the "StyleOptions" property.
table->set_StyleOptions(table->get_StyleOptions() | TableStyleOptions::LastRow | TableStyleOptions::LastColumn);
