Thanks, but I had already read these discussions (hope the grammar is
correct...), and thought I understood them. But my exact problem: If I
resize a xterm, in most cases curses prints crap (if it does not crash
python). And I could not find any python-curses application that is
displayed correctly after a terminal resize.
I hope nobody will kill me, 'cause I'm a spammer; here is my example:
------
import curses
def gettermres():
"""
returns the current terminal size in columns and lines
"""
import struct, fcntl, sys, termios
lines, cols = struct.unpack("HHHH",
fcntl.ioctl(sys.stdout.fileno(),termios.TIOCGWINSZ, struct.pack("HHHH",
0, 0, 0, 0)))[:2]
return cols, lines
def splitwin(scr, extend1, axis=0, isPercent=True,
useFullScreen=False):
"""
splits the scr in 2 windows and return both
extend1 is the size of the first window
axis=0 --> split horizontal
axis=1 --> split vertical
if isPercent is False, extend1 will be interpreted as absolut size
"""
if isPercent and not 0 < extend1 < 100:
raise "extend1 must be between 0 and 100"
if not axis in (0,1):
raise "axis must be 0 or 1"
if useFullScreen:
res = [0,0]
res[1], res[0] = gettermres()
pos = (0,0)
else:
res = scr.getmaxyx()
pos = scr.getbegyx()
size1 = list(res)
size2 = list(res)
if isPercent:
totallen = float(res[axis])
size1[axis] = int( totallen*extend1 / 100 )
else:
size1[axis] = extend1
size2[axis] = res[axis] - size1[axis]
start1 = list(pos)
start2 = list(pos)
start2[axis] = size1[axis]
win1 = curses.newwin(size1[0], size1[1], start1[0], start1[1])
win2 = curses.newwin(size2[0], size2[1], start2[0], start2[1])
return win1, win2
def startcurses(stdscr):
curses.use_default_colors() # transparency
curses.init_pair(2, curses.COLOR_GREEN, -1)
while 1:
curses.setupterm()
winTop, winBottom = splitwin(stdscr, 80, useFullScreen=True)
winLeft, winRight = splitwin(winTop, 50, 1)
winLeft.border()
winLeft.noutrefresh()
winRight.border()
winRight.addstr(1,1,"hallo", curses.color_pair(2))
winRight.noutrefresh()
winBottom.border()
winBottom.noutrefresh()
curses.doupdate()
k = winLeft.getch()
if k == ord('q'):
break
curses.wrapper(startcurses)
