Public Methods

Method	Description
AddContextMenu ( this clb ) : void	Adds a useful context menu to a checked list box
AsyncWaitOnGUIThread ( this condition, System.Action onComplete ) : void	OnComplete will be invoked on the GUI thread when condition is true. This function need not be called from the GUI thread.
Center ( this rectangle ) : Point	The point at the center of the rectangle.
CenteredAround ( this size, Point location ) : Point	Returns the point where this is centered around the location.
ConstrainedTo ( this size, Size container ) : Size	If size fits inside the containing size, the original size is returned. Otherwise, a size is returned that is as large as possible, fits within the container, and has the same aspect ratio as the original size.
DrawArrow ( this graphics, Rectangle area, ArrowType arrowType, double ratio = 1.0/3.0 ) : void	Draws an arrow in the specified rectangle with the specified direction. Ratio is used on recursive calls withing this function to adjust the sizing of bidirectional arrows
DrawFixationCross ( this graphics, Point center ) : void	Draws a fixation cross centered at location
EnableValidation ( this textBox, bool>.Func isValid, System.Action onValidTextEntered = null ) : void	Adds fancy validation logic using isValid to determine the validity of the textbox's content. The onValidTextEntered function, if not null, is called from the TextChanged event only if the new text was valid.
GUIInvoke ( this action ) : void	Invokes the action on the GUI thread if necessary.
IsValid ( this textBox ) : bool	Returns true iff there is no validation function installed for the text box or if the current text value is declared valid by the installed validation function
ReverseTabOrder ( this control ) : void	Reverses the tab order of the control's children.
ToLabel ( this text, DockStyle dockStyle = DockStyle.Top, ContentAlignment align = ContentAlignment.TopLeft, bool autoSize = true ) : Label	Creates a label from text. The default DockStyle is set for usage in a top-down FlowLayoutPanel.
TryLoadImage ( this path, Image &image ) : bool	If Image.FromFile succeeds and the result is not null, returns true and assigns the loaded value to image. Otherwise, image is set to null and false is returned.

ConstrainedTo() public static method

If size fits inside the containing size, the original size is returned. Otherwise, a size is returned that is as large as possible, fits within the container, and has the same aspect ratio as the original size.

public static ConstrainedTo ( this size, Size container ) : Size
size	this
container	System.Drawing.Size
return	System.Drawing.Size

DrawArrow() public static method

Draws an arrow in the specified rectangle with the specified direction. Ratio is used on recursive calls withing this function to adjust the sizing of bidirectional arrows
