mini-term in qt4

mini-term in qt4.

Today's features:
  • A simple terminal-like application built from a qt4 class that can be used for other stuff too.
  • The present application can run shell commands and has copy/paste (ctrl-c, ctrl-v) capabilitity.
  • Another example of the Windows-like api so that C/C++ code can run in Qt4.
  • Runs the custom code (terminal in this case) inside a QT 'exec' loop... sorta. We call it 'run()'.

Updated 01-18-2013 at 06:54 AM by NullTerminator (add sed cmd for non prinitng char)

A couple sample to strip unreadable characters from a binary file
Code:
# Translate junk characters into newlines while squeezing
C:\Temp>tr -sc '[\011\012\015\040-\176]' \n < blob_of_data.txt

# Translate and discard single character lines
C:\Temp>tr -sc '[\011\012\015\040-\176]' \n < blob_of_data.txt | awk "length($0) > 1"
# replace a bad character in a file
0xa0 is a 'non breaking space' that appears often when...

Quick and dirty plotting with Haskell: Supplement

Posted 01-14-2013 at 11:54 PM by hydraMax (Bits and Pixels)

I just wanted to add a brief note to my previous post: It is also quite simple to do a plot with multiple functions. The following code gives the graph seen in the attached PNG:

Code:
h> import Graphics.Gnuplot.Simple
h> let f x = 3 - 2*x + 4*x**2
h> let g x = 8*x - 2
h> let h a x = g a * (x - a) + f a
h> plotFuncs [] (linearScale 1000 (-10,10)) [f, g, h (-5)]
f(x) is a function, g(x) is the derivative of f(x), and...

QT4 -- Having trouble with qInitResouces_<appname>() ?

Having trouble with qInitResouces_<appname>()?

Try this.
Code:
#ifdef Q_INIT_RESOURCE
#undef Q_INIT_RESOURCE
#endif

#define Q_INIT_RESOURCE(name) extern void qInitResources_##name()
The version of this macro in qglobal.h could never have ever worked.

If you enjoy digging into the low level stuff, I think you'll be amused by the context of this bug. ;-)
