X$SET_FUNCTION

(display, gc_id, function)

Arguments

function

The new value for the function member of the graphics context. The function member describes how the new destination bits are to be computed from the source bits and the old destination bits. Table 2-7 lists the valid values for function. The default value is 3 for X$C_GX_COPY.

X$SET_INPUT_FOCUS

(display, focus_id, revert_to, time)

Arguments

focus_id

The window identifier of the window in which you want to set the input focus.

The identifier of the window was originally returned by CREATE SIMPLE WINDOW or CREATE WINDOW. When the window identifier is specified, that window becomes the keyboard's focus window. When keyboard events are normally reported to this window (or its inferiors), the events continue to be reported. Otherwise, the event is reported with respect to the focus window.

One of the following predefined values can be specified instead of the window identifier:

X$C_POINTER_ROOT
X$C_NONE

revert_to

Where the input focus moves to when the focus window becomes unviewable.

One of the following predefined values can be specified:

X$C_REVERT_TO_PARENT
X$C_REVERT_TO_POINTER_ROOT
X$C_REVERT_TO_NONE

X$SET_LINE_ATTRIBUTES

(display, gc_id, line_width, line_style, cap_style, join_style)

Arguments

line_style

Specifies the line style member. Line style defines the pattern of a line. The predefined values for line_style are as follows:

X$C_LINE_SOLID
X$C_LINE_DOUBLE_DASH
X$C_LINE_OFF_DASH

Other values specified in this argument are not valid.

cap_style

Specifies the cap style member, which defines how the endpoints of a path are drawn. The predefined values for cap_style are as follows:

X$C_CAP_NOT_LAST
X$C_CAP_BUTT
X$C_CAP_ROUND
X$C_CAP_PROJECTING

Other values specified in this argument are not valid. The default value is X$C_CAP_BUTT.

join_style

The join style. The join style defines how corners are drawn for wide lines. The predefined values for join_style are as follows:

X$C_JOIN_MITER
X$C_JOIN_ROUND
X$C_JOIN_BEVEL

Other values specified in this argument are not valid. The default value is X$C_JOIN_MITER.
