is_line_hidden
Integer is_line_hidden ();
This function returns a non-zero value if the current line is hidden. It will return zero if the current line is visible.
set_line_hidden
set_line_hidden
Void set_line_hidden (Integer flag);
If the parameter flag is non-zero, the current line will be given
the hidden attribute. This means that it will not be displayed. If the
parameter is zero, the hidden attribute will be turned off.
set_region_hidden, is_line_hidden
set_region_hidden
Void set_region_hidden (Integer flag);
This function may be used to hide the lines in a region. If flag is
non-zero, all lines in the region will be hidden. If it is zero, the
lines in the region will be made visible.
set_line_hidden, is_line_hidden, skip_hidden_lines_forward
skip_hidden_lines_backward
Void skip_hidden_lines_backward (Integer type);
This function may be used to move backward across either hidden or non-hidden
lines depending upon whether the parameter type is non-zero or zero.
If type is non-zero, the Point is moved backward across hidden lines
until a visible line is reached. If type is zero, visible lines will
be skipped instead. If the top of the buffer is reached before the
appropriate line is reached, the Point will be left there.
Note: The functions up and down are insensitive to whether or not
a line is hidden.
skip_hidden_lines_forward, is_line_hidden
skip_hidden_lines_forward
Void skip_hidden_lines_forward (Integer type);
This function may be used to move forward across either hidden or non-hidden
lines depending upon whether the parameter type is non-zero or zero.
If type is non-zero, the Point is moved forward across hidden lines
until a visible line is reached. If type is zero, visible lines will
be skipped instead. If the end of the buffer is reached before the
appropriate line is reached, the Point will be left there.
Note: The functions up and down are insensitive to whether or not
a line is hidden.
