Configuration Settings
^^^^^^^^^^^^^^^^^^^^^^
CONFIG_NX
Enables overall support for graphics library and NX
CONFIG_NX_MULTIUSER
Configures NX in multi-user mode
CONFIG_NX_NPLANES
Some YUV color formats requires support for multiple planes, one for each
color component. Unless you have such special hardware, this value should be
undefined or set to 1.
CONFIG_NX_DISABLE_1BPP, CONFIG_NX_DISABLE_2BPP,
CONFIG_NX_DISABLE_4BPP, CONFIG_NX_DISABLE_8BPP,
CONFIG_NX_DISABLE_16BPP, CONFIG_NX_DISABLE_24BPP, and
CONFIG_NX_DISABLE_32BPP
NX supports a variety of pixel depths. You can save some memory by disabling
support for unused color depths.
CONFIG_NX_PACKEDMSFIRST
If a pixel depth of less than 8-bits is used, then NX needs to know if the
pixels pack from the MS to LS or from LS to MS
CONFIG_NX_MOUSE
Build in support for mouse input.
CONFIG_NX_KBD
Build in support of keypad/keyboard input.
CONFIG_NXTK_BORDERWIDTH
Specifies with with of the border (in pixels) used with framed windows.
The default is 4.
CONFIG_NXTK_BORDERCOLOR1 and CONFIG_NXTK_BORDERCOLOR2
Specify the colors of the border used with framed windows.
CONFIG_NXTK_BORDERCOLOR2 is the shadow side color and so is normally darker.
The default is medium and dark grey, respectively
CONFIG_NXTK_AUTORAISE
If set, a window will be raised to the top if the mouse position is over a
visible portion of the window. Default: A mouse button must be clicked over
a visible portion of the window.
CONFIG_NXFONTS_CHARBITS
The number of bits in the character set. Current options are only 7 and 8.
The default is 7.
CONFIG_NXFONT_SANS
At present, there is only one font. But if there were were more, then this
option would select the sans serif font.
NX Multi-user only options:
CONFIG_NX_BLOCKING
Open the client message queues in blocking mode. In this case,
nx_eventhandler() will not return until a message is received and processed.
CONFIG_NX_MXSERVERMSGS and CONFIG_NX_MXCLIENTMSGS
Specifies the maximum number of messages that can fit in the message queues.
No additional resources are allocated, but this can be set to prevent
flooding of the client or server with too many messages (CONFIG_PREALLOC_MQ_MSGS
controls how many messages are pre-allocated).
