Public Method setFillingGradient

static void setFillingGradient(int mode, int ramp, int fromColor, int toColor)

Throws:

• ILCDException

_INSERT_METHOD_SIGNATURE_HERE_

Parameter	Range	Description
mode	0 ... 4	gradient mode (see below)
ramp	0 ... max[width, height]	pixels until toColor is reached (0 = maximum)
fromColor	0x000000 ... 0xFFFFFF	color value at beginning of gradient
toColor	0x000000 ... 0xFFFFFF	color value at end of gradient

Sets the active fill pattern to a gradient going from fromColor to toColor. All subsequent filling will be done with a gradient dependent on mode, which can be:

Mode	from red to blue	Description
GRADIENT_HORIZONTAL		ramp from left
GRADIENT_VERTICAL		ramp from top
GRADIENT_HORIZONTAL_SYMMETRICAL		ramp from left and right
GRADIENT_VERTICAL_SYMMETRICAL		ramp from top and bottom
GRADIENT_BUTTONIZED		ramp from all directions

• If ramp is set to 0 or the area to fill is smaller than ramp in the according direction, the gradient fades over the complete area disregarding the set ramp value.
• In any other case, the gradient starts from fromColor and gradually changes to toColor for ramp pixels. The rest of the according area is filled with the solid toColor.
• The ramp is scaled by the corresponding coordinate scale factor (refer to Control.setRowCoordinatesScaling(int, int) for horizontal and Control.setColumnCoordinatesScaling(int, int) for vertical gradients). For buttonized gradients, the smaller of those two scale factor is taken into account.
• The default fill pattern is a solid color (see Attribute.setFillingColor(int)) with a color_value of 0x000000 (black). It will be automatically set to default on startup and by the methods General.resetAll() or General.rebootPanelController().

Example

Attribute.setFillingGradient(Attribute.GRADIENT_BUTTONIZED, 20, 0xFFFFFF, 0x00FF00);

All future filling will be done with a gradient that fades from white to blue for 20 pixels in all directions. Filling an area with this pattern will give it a three-dimensional "buttonized" look.
