attroff, wattroff, attron, wattron, attrset, wattrset, color_set, wcolor_set, standend, wstandend, standout, wstandout - curses character and window attribute control routines |
#include <curses.h> |
These routines manipulate the current attributes of the named window. The current attributes of a window apply to all characters that are written into the window with waddch, waddstr and wprintw. Attributes are a property of the character, and move with the character through any scrolling and insert/delete line/character operations. To the extent possible, they are displayed as appropriate modifications to the graphic rendition of characters put on the screen. The routine attrset sets the current attributes of the given window to attrs. The routine attroff turns off the named attributes without turning any other attributes on or off. The routine attron turns on the named attributes without affecting any others. The routine standout is the same as attron(A_STANDOUT). The routine standend is the same as attrset(A_NORMAL) or attrset(0), that is, it turns off all attributes. The routine color_set sets the current color of the given window to the foreground/background combination described by the color_pair_number. The parameter opts is reserved for future use, applications must supply a null pointer. The routine wattr_get returns the current attribute and color pair for the given window; attr_get returns the current attribute and color pair for stdscr. The remaining attr_* functions operate exactly like the corresponding attr* functions, except that they take arguments of type attr_t rather than int. The routine chgat changes the attributes of a given number of characters starting at the current cursor location of stdscr. It does not update the cursor and does not perform wrapping. A character count of -1 or greater than the remaining window width means to change attributes all the way to the end of the current line. The wchgat function generalizes this to any window; the mvwchgat function does a cursor move before acting. In these functions, the color argument is a color-pair index (as in the first argument of init_pair, see curs_color(3X)). The opts argument is not presently used, but is reserved for the future (leave it NULL). |
Attributes |
The following video attributes, defined in <curses.h>, can be passed to the routines attron, attroff, and attrset, or OR’ed with the characters passed to addch. |
