public sealed class PreferredWidth

Properties

Name	Description
Type { get; }	Gets the unit of measure used for this preferred width value.
Value { get; }	Gets the preferred width value. The unit of measure is specified in the `Type` property.

Methods

Name	Description
static FromPercent(double)	A creation method that returns a new instance that represents a preferred width specified as a percentage.
static FromPoints(double)	A creation method that returns a new instance that represents a preferred width specified using a number of points.
override Equals(object)	Determines whether the specified object is equal in value to the current object.
Equals(PreferredWidth)	Determines whether the specified `PreferredWidth` is equal in value to the current `PreferredWidth`.
override GetHashCode()	Serves as a hash function for this type.
override ToString()	Returns a user-friendly string that displays the value of this object.

Fields

Name	Description
static readonly Auto	Returns an instance that represents the “preferred width is not specified” value.

Remarks

Preferred width can be specified as a percentage, number of points or a special “none/auto” value.

The instances of this class are immutable.

Examples

Shows how to set a table to auto fit to 50% of the width of the page.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

Table table = builder.StartTable();
builder.InsertCell();
builder.Write("Cell #1");
builder.InsertCell();
builder.Write("Cell #2");
builder.InsertCell();
builder.Write("Cell #3");

table.PreferredWidth = PreferredWidth.FromPercent(50);

doc.Save(ArtifactsDir + "DocumentBuilder.InsertTableWithPreferredWidth.docx");

Shows how to set a preferred width for table cells.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Table table = builder.StartTable();

// There are two ways of applying the "PreferredWidth" class to table cells.
// 1 -  Set an absolute preferred width based on points:
builder.InsertCell();
builder.CellFormat.PreferredWidth = PreferredWidth.FromPoints(40);
builder.CellFormat.Shading.BackgroundPatternColor = Color.LightYellow;
builder.Writeln($"Cell with a width of {builder.CellFormat.PreferredWidth}.");

// 2 -  Set a relative preferred width based on percent of the table's width:
builder.InsertCell();
builder.CellFormat.PreferredWidth = PreferredWidth.FromPercent(20);
builder.CellFormat.Shading.BackgroundPatternColor = Color.LightBlue;
builder.Writeln($"Cell with a width of {builder.CellFormat.PreferredWidth}.");

builder.InsertCell();

// A cell with no preferred width specified will take up the rest of the available space.
builder.CellFormat.PreferredWidth = PreferredWidth.Auto;

// Each configuration of the "PreferredWidth" property creates a new object.
Assert.AreNotEqual(table.FirstRow.Cells[1].CellFormat.PreferredWidth.GetHashCode(),
    builder.CellFormat.PreferredWidth.GetHashCode());

builder.CellFormat.Shading.BackgroundPatternColor = Color.LightGreen;
builder.Writeln("Automatically sized cell.");
