DrawingBase Methods

Defines the parent-child relationship between two visuals.

Adjusts to the nearest bar and price. This method is called on Mouse Up event. User must also calculate the Bar index and price.

Gets the bar index from point x

Calculates bar index from time

Calculates the first bar painted

Calculate the first bar painted

Calculates the price from Y

Calculates the X point

Returns the Y point from entry price

Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier.

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey.

Clones a chartObject

Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.

Checks for the hittest

Draws the object

Draws the handle

Determines whether a provided DependencyObject is equivalent to the current DependencyObject.

Extends a line to the left

Extends a line to the right

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Returns the common ancestor of two visual objects.

Gets the angle of two points

Calculates the extended point value of a line

Returns the handle point

Returns the handle cursor

Returns the rectangle handle

Gets a hash code for this DependencyObject.

Returns the distance between 2 points

Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject.

Gets the Type of the current instance.

Returns the current effective value of a dependency property on this instance of a DependencyObject.

Returns a specified child Visual for the parent ContainerVisual.

Returns the top-most visual object of a hit test by specifying a Point.

Initiates a hit test on the ContainerVisual by using the HitTestFilterCallback and HitTestResultCallback objects.

Determines whether a geometry value is within the bounds of the visual object.

Determines whether a point coordinate value is within the bounds of the DrawingVisual object.

Checks if the object intersects with another object

Re-evaluates the effective value for the specified dependency property

Determines whether the visual object is an ancestor of the descendant visual object.

Determines whether the visual object is a descendant of the ancestor visual object.

Appends the message to the log tab in Main View

Hit test. Return value: -1 - no hit, 0 - hit anywhere, > 1 - handle number

Creates a shallow copy of the current Object.

Moves the object to a new location

Moves the handle to a new point

Raised when the actual height of the view changes

Raised when the actual width of the view changes

Raised when the bar space changes

Raised when the bar width changes

Called when the DPI at which this View is rendered changes.

Raised when the lastBarPainted changes

Raised when the Y-Axis maximum is changed

Raised when the Y-Axis minimum is changed

Invoked whenever the effective value of any dependency property on this DependencyObject has been updated. The specific dependency property that changed is reported in the event data.

Called when the VisualCollection of the visual object is modified.

Called when the parent of the visual object is changed.

Converts a Point in screen coordinates into a Point that represents the current coordinate system of the Visual.

Converts a Point that represents the current coordinate system of the Visual into a Point in screen coordinates.

Prints the message to the Output view

Prints the message to the output view

Returns the local value of a dependency property, if it exists.

Refresh the view

Removes the parent-child relationship between two visuals.

Opens the DrawingVisual object for rendering. The returned DrawingContext value can be used to render into the DrawingVisual.

Rounds the price points to the instrument tickSize

Sets the value of a dependency property without changing its value source.

Sets the local value of a dependency property, specified by its dependency property identifier.

Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property.

Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property.

Returns a string that represents the current object.

Returns a transform that can be used to transform coordinates from the Visual to the specified Visual ancestor of the visual object.

Returns a transform that can be used to transform coordinates from the Visual to the specified Visual3D ancestor of the visual object.

Returns a transform that can be used to transform coordinates from the Visual to the specified visual object descendant.

Returns a transform that can be used to transform coordinates from the Visual to the specified visual object.
