Overview

Note:

This class is untracked and should not be derived from nor instances extended!

Represents a collection of GraphicGradientStop values for use with CreateLinearGradientBrush and CreateRadialGradientBrush.

The stops are maintained in order of position. If two or more stops are added with the same position, then the one(s) added later come later. This can be useful for producing discontinuities in the colour gradient. Notice that this class is write-once; you can’t modify the stops once they had been added.

Constructor Details

#initialize(startCol = Wx::TRANSPARENT_COLOUR, endCol = Wx::TRANSPARENT_COLOUR) ⇒ Wx::GraphicsGradientStops

Initializes the gradient stops with the given boundary colours.

Creates a Wx::GraphicsGradientStops instance with start colour given by startCol and end colour given by endCol.

Parameters:

• startCol (Wx::Colour) (defaults to: Wx::TRANSPARENT_COLOUR)
• endCol (Wx::Colour) (defaults to: Wx::TRANSPARENT_COLOUR)
