Creates an arc/curve (used to create circles, or parts of circles).

Creates an arc/curve between two tangents on the canvas.

Creates an arc/curve between two tangents on the canvas.

begins a path, or resets the current path.

Adds a point to the current path by using the specified control points that represent a cubic Bézier curve.

A cubic bezier curve requires three points. The first two points are control points that are used in the cubic Bézier calculation and the last point is the ending point for the curve. The starting point for the curve is the last point in the current path. If a path does not exist, use the beginPath() and moveTo() methods to define a starting point.

Clears the specified pixels within a given rectangle.

Clears the specified pixels within a given rectangle.

Clips a region of any shape and size from the original canvas.

Once a region is clipped, all future drawing will be limited to the clipped region (no access to other regions on the canvas). You can however save the current canvas region using the save() method before using the clip() method, and restore it (with the restore() method) any time in the future.

Creates a path from the current point back to the starting point.

Creates a linear gradient object. The gradient can be used to fill rectangles, circles, lines, text, etc.

Returns: Object.

Repeats the specified element in the specified direction. The repeated element can be used to draw/fill rectangles, circles, lines etc.

Returns: Object.

Repeats the specified element in the specified direction. The repeated element can be used to draw/fill rectangles, circles, lines etc.

Moves the path to the specified point in the canvas, without creating a line.

Use the stroke() method to actually draw the path on the canvas.

Adds a point to the current path by using the specified control points that represent a quadratic Bézier curve.

A quadratic Bézier curve requires two points. The first point is a control point that is used in the quadratic Bézier calculation and the second point is the ending point for the curve. The starting point for the curve is the last point in the current path. If a path does not exist, use the beginPath() and moveTo() methods to define a starting point.

Creates a rectangle.

Creates a rectangle.

Returns previously saved path state and attributes.

Method rotates the current drawing.

The rotation will only affect drawings made AFTER the rotation is done.

Saves the state of the current context.

Scales the current drawing, bigger or smaller.

Scales the current drawing, bigger or smaller.

Sets the line dash pattern.

Resets the current transform to the identity matrix, and then runs transform() with the same arguments.

The transformation will only affect drawings made after the transform() method is called. The transform() method behaves relatively to other transformations made by rotate(), scale(), translate(), or transform(). Example: If you already have set your drawing to scale by two, and the transform() method scales your drawings by two, your drawings will now scale by four.

Draws the path you have defined.

Draws a rectangle (no fill). The default color of the stroke is black.

Draws a rectangle (no fill). The default color of the stroke is black.

Replaces the current transformation matrix.

The transformation will only affect drawings made after the transform() method is called. The transform() method behaves relatively to other transformations made by rotate(), scale(), translate(), or transform(). Example: If you already have set your drawing to scale by two, and the transform() method scales your drawings by two, your drawings will now scale by four.

When you call a method such as fillRect() after translate(), the value is added to the x- and y-coordinate values.

• Control

  • Label

Represents a label control.

public class Label : Control, IButtonControl, IImage, IErrorProvider, ICommandSource

Public Class Label
    Inherits Control
    Implements IButtonControl, IImage, IErrorProvider, ICommandSource

Constructors

Label()

Initializes a new instance of the Label class.

Label(text)

Initializes a new instance of the Label class.

Label(text, location, size)

Initializes a new instance of the Label class.

Properties

Boolean: Returns or sets a value indicating that the control can display HTML in the Text property. (Default: False)

Newlines (CRLF) are converted to <BR/> when AllowHtml is false, or when AllowHtml is true and the text doesn't contain any HTML.

AnchorStyles: Returns or sets the edges of the container to which a control is bound and determines how a control is resized with its parent. (Default: Top, Left)

Boolean: Returns or sets whether the ellipsis character (...) appears at the right edge of the label, denoting that the text extends beyond the size of the label. (Default: False)

Boolean: Returns or sets a value that indicates whether the control resizes based on its contents. (Default: False)

Since 3.5.6 Auto sizing behavior in the Label control is slightly different from other controls. When the label is a child of a standard container (i.e. Panel, Form, Page, GroupBox) and it's anchored to the right, auto sizing grows or shrinks the label's width preserving the left position. When the label is a child of a container with a custom LayoutEngine (i.e. FlexLayoutPanel, FlowLayoutPanel, TableLayoutPanel) the auto sizing behavior is the same as all other controls. You can change the default behavior using the AppContext switch "LabelSelfSize". See System.AppContext to learn how to set the switch. In code, you can set it in a static Program constructor:

class Program {
  static void Program() {
    AppContext.SetSwitch("LabelSelfSize", false);
  }
}

Boolean: Returns or sets whether a tooltip is displayed when the text extends beyond the size of the label. (Default: False)

The auto tooltip is set on the browser using the title attribute managed by the browser, does not use the themed tooltip managed by Wisej.NET.

BorderStyle: Indicates the border style for the control. (Default: None)

CharacterCasing: Returns or sets the case of the text to display to the user. (Default: Normal)

ICommand: Returns or sets the ICommand implementation to invoke. (Default: null)

DialogResult: Returns or sets a value that is returned to the parent form when the button is clicked. (Default: None)

DockStyle: Returns or sets which control borders are docked to its parent control and determines how a control is resized with its parent. (Default: None)

Boolean: Enables or disables the browser's context menu. (Default: False)

Image: Returns or sets the image that is displayed on a Label.

ContentAlignment: Returns or sets the alignment of an image that is displayed in the control. (Default: MiddleCenter)

Int32: Returns or sets the image list index value of the image displayed on the label control. (Default: -1)

Throws:

• ArgumentOutOfRangeException The specified index is less than -1.

String: Returns or sets the key accessor for the image in the ImageList. (Default: "")

ImageList: Returns or sets the ImageList that contains the images to display in the Label control. (Default: null)

String: Returns or sets the theme name or URL for the image to display in the Label.

Boolean: EXPERIMENTAL: Return or sets whether the label resize itself when AutoSize is true and it's in a container using the default layout engine: i.e.: Panel, Form, Page, GroupBox, UserControl. Since 3.5.6 (Default: True)

When self sizing is active (default for standard containers) an auto sizing label will always grow to the right side, even when anchored right, preserving it's left position. This is the default behavior in WinForms applications.

Boolean: EXPERIMENTAL: Default value for the SelfSize property. Since 3.5.6

The default is true. You can set the value by code or using AppContext switches: AppContext.SetSwitch("LabelSelfSize", false);

String: Returns or sets the text associated with this control. (Default: "")

Newlines (CRLF) are converted to <BR/> when AllowHtml is false, or when AllowHtml is true and the text doesn't contain any HTML.

ContentAlignment: Returns or sets the alignment of text in the label. (Default: TopLeft)

Boolean: Returns or sets whether the first character that is preceded by an ampersand (&) is used as the mnemonic key of the control. (Default: True)

Methods

Generates a Click event for the LinkLabel control.

EventHandler Fired when the Command property value changes.
