Thickness Structure
Assembly: PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation
[LocalizabilityAttribute(LocalizationCategory.None, Readability = Readability.Unreadable)] [TypeConverterAttribute(typeof(ThicknessConverter))] public struct Thickness : IEquatable<Thickness>
<Thickness .../>
<object property="left"/> - or - <object property="left,top"/> - or - <object property=" left,top,right,bottom" ... />
XAML Values
 Note |
|---|
Values need not include the decimal point explicitly when specified as a string. The string "1" provided in XAML evaluates to a value of 1.0 when referenced in code. |
The Thickness type exposes the following members.
| Name | Description | |
|---|---|---|
|
Thickness(Double) | Initializes a new instance of the Thickness structure that has the specified uniform length on each side. |
|
|
Thickness(Double, Double, Double, Double) | Initializes a new instance of the Thickness structure that has specific lengths (supplied as a Double) applied to each side of the rectangle. |
| Name | Description | |
|---|---|---|
|
Bottom | Gets or sets the width, in pixels, of the lower side of the bounding rectangle. |
|
|
Left | Gets or sets the width, in pixels, of the left side of the bounding rectangle. |
|
|
Right | Gets or sets the width, in pixels, of the right side of the bounding rectangle. |
|
|
Top | Gets or sets the width, in pixels, of the upper side of the bounding rectangle. |
| Name | Description | |
|---|---|---|
|
|
Equals(Object) | Compares this Thickness structure to another Object for equality. (Overrides ValueType.Equals(Object).) |
|
|
Equals(Thickness) | Compares this Thickness structure to another Thickness structure for equality. |
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetHashCode | Returns the hash code of the structure. (Overrides ValueType.GetHashCode().) |
|
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ToString | Returns the string representation of the Thickness structure. (Overrides ValueType.ToString().) |
| Name | Description | |
|---|---|---|
|
Equality | Compares the value of two Thickness structures for equality. |
|
|
Inequality | Compares two Thickness structures for inequality. |
You can specify Thickness values in two ways. If you pass four Double values to the structure, they represent the Left, Top, Right and Bottom sides, respectively, of the bounding rectangle. You can also supply a single value, which applies a uniform value to all four sides of the bounding rectangle.
The following example shows how to create an instance of a Thickness structure and set its properties by using Extensible Application Markup Language (XAML) and code.
myBorder2 = new Border(); myBorder2.BorderBrush = Brushes.SteelBlue; myBorder2.Width = 400; myBorder2.Height = 400; myThickness = new Thickness(); myThickness.Bottom = 5; myThickness.Left = 10; myThickness.Right = 15; myThickness.Top = 20; myBorder2.BorderThickness = myThickness;

The Margin property is a property of the FrameworkElement base element, and is thus inherited by a variety of controls and other elements. |
