C# Class Longkong.ColorPicker.Controls.ColorPanel

Constructor. Initializes all of the components and member fields and configures the control for double buffering support.

Clean up any resources being used.

Overrides the base class' OnLoad method and instantiates a new DragForm object that will be used to create the visual drag effect when adding the currently selected color to the color swatch panel.

Overrides the panel's OnPaint method to performs all of the painting operations.

Processes the selected color.

Handles the ComponentValueChanged event that the ColorSpace raises when the value of one of its components is changed by way of a keyboard user input. The color spaces are synced up and the color panels updated.

Calculates the points needed to draw the left triangle pointer for the value strip.

Calculates the points needed to draw the right triangle pointer for the color slider.

Determines the color slider left triangle pointer invalidation region.

Determines the color slider right triangle pointer invalidation region.

Required method for Designer support - do not modify the contents of this method with the code editor.

Invalidate the color slider arrow regions.

Handles the SelectedColorSpaceComponentChanged event raised by the color spaces. When this occurs, the color slider arrow regions and the color panels are updated.

Updates the color field panel.

Updates the color panels and the hex value.

Updates the color slider.

Updates the color spaces with the new hex value and makes sure that the necessary components are updated (color field, color slider, etc).

Updates the hexadecimal text value.

Handles the KeyDown event raised by the hexTextBox object.

Handles the KeyUp event raised by the hexTextBox object.

Handles the MouseDown event raised by the picColorSlider object. When the user clicks on the color slider, the arrow regions are updated to assume the clicked y-coordinate as their new vertical position.

Handles the GetFeedback event raised by picCurrentColor. We don't want to use the default cursors (I think they are intrusive). Setting the UseDefaultCursors property of the GiveFeedbackEventArgs object and setting the cursor to the hand cursor takes care of this for us.

Handles the MouseDown event raised by the picCurrentColor object.

Handles the QueryContinueDrag event raised by picCurrentColor. If the Action is anything other than Cancel or Drop, the location of the transparent form is updated.

Handles the Tick event raised by the sliderTimer object. This is used to guarantee fluidity between two different points on the color slider when the arrows are being dragged. Without this, the currently selected color panel and the updated structure values (RGB/HEX) jump awkwardly between points. This will probably be changed to a threaded solution since FXCop is complaining about the tick frequency.
