config EXAMPLES_NXLINES
	bool "NX graphics lines example"
	default n
	---help---
		Enable the X graphics lines example

if EXAMPLES_NXLINES

config EXAMPLES_NXLINES_VPLANE
	int "Graphics Plane"
	default 0
	---help---
		The plane to select from the frame-buffer driver for use in the test.  Default: 0

config EXAMPLES_NXLINES_DEVNO
	int "Graphics Device Number"
	default 0
	---help---
		The LCD device to select from the LCD driver for use in the test: Default: 0

config EXAMPLES_NXLINES_DEFAULT_COLORS
	bool "Use default colors"
	default y
	---help---
		Select this option to let the NXLINES example pick the colors.  Otherwise,
		you may select the exact colors to use in hex format.

config EXAMPLES_NXLINES_BGCOLOR
	hex "Background Color"
	default 0x00
	depends on !EXAMPLES_NXLINES_DEFAULT_COLORS
	---help---
		The color of the background.  Default depends on EXAMPLES_NXLINES_BPP.

config EXAMPLES_NXLINES_LINEWIDTH
	int "Line Width"
	default 16
	---help---
		Selects the width of the lines in pixels (default: 16)

config EXAMPLES_NXLINES_LINECOLOR
	hex "Line Color"
	default 0x00
	depends on !EXAMPLES_NXLINES_DEFAULT_COLORS
	---help---
		The color of the central lines drawn in the background window. Default
		depends on EXAMPLES_NXLINES_BPP (there really is no meaningful default).

config EXAMPLES_NXLINES_BORDERWIDTH
	int "Border Width"
	default 16
	---help---
		The width of the circular border drawn in the background window. (default: 16).

config EXAMPLES_NXLINES_BORDERCOLOR
	hex "Border Color"
	default 0x00
	depends on !EXAMPLES_NXLINES_DEFAULT_COLORS
	---help---
		The color of the circular border drawn in the background window. Default
		depends on EXAMPLES_NXLINES_BPP (there really is no meaningful default).

config EXAMPLES_NXLINES_CIRCLECOLOR
	hex "Circle Color"
	default 0x00
	depends on !EXAMPLES_NXLINES_DEFAULT_COLORS
	---help---
		The color of the circular region filled in the background window. Default
		depends on EXAMPLES_NXLINES_BPP (there really is no meaningful default).

config EXAMPLES_NXLINES_BPP
	int "Bits Per Pixel"
	default 8
	---help---
		Pixels per pixel to use.  Valid options include 2, 4, 8, 16, 24, and 32.
		Default is 16.

config EXAMPLES_NXLINES_EXTERNINIT
	bool "External Device Initialization"
	default false
	---help---
		The driver for the graphics device on this platform requires some unusual
		initialization.  This is the for, for example, SPI LCD/OLED devices.  If
		this configuration is selected, then the platform code must provide an LCD
		initialization function with a prototype like:

		#ifdef NX_LCDDRIVER
		FAR struct lcd_dev_s *up_nxdrvinit(unsigned int devno);
		#else
		FAR struct fb_vtable_s *up_nxdrvinit(unsigned int devno);
		#endif
