Parameters

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, an OnPaint event object. The code performs the following actions:

• Creates a new LinearGradientBrush.

• Uses this brush to draw a rectangle to the screen that has a linear, left-to-right transition of colors.

• Rotates the LinearGradientBrush by 90 degrees and scales the gradient.

• Draws the rectangle, with the rotated and scaled gradient, to the screen.

• Translates the rectangle so that it has a linear gradient running from top to bottom.

• Draws the translated rectangle to the screen.

Notice that there are three rectangles displayed the top one showing the left-to-right gradient, the middle one showing the rotated and scaled gradient, and the bottom one showing the final, translated gradient.

      // Draw a rectangle to the screen using the LinearGradientBrush.
      e->Graphics->FillRectangle( myLGBrush, myRect );

      // Rotate the LinearGradientBrush.
