#### Change text color of uicontrol whose 'Enable' property is 'off'

I would like to change the text color of a uicontrol whose 'Enable' property is set to 'off'

Is there a way to do this?

Does being not-enabled specifically prevent this? Are you asking for an automatic method, like whenever you set something's enable to "off" it automatically recolors it too? And are you sure you dont just want to set "enable" to "disabled" (I've never found a good use for enable=off)

f=findobj(gcf,'type','uicontrol','enable','off')
set(f,'color',[1 0 0])

Does it?  I did not know that.  Is there a workaround?

I'm not sure exactly what you mean by 'automatic'.  I don't want to change any Matlab defaults.  I just would like to know if there is a way to change the color of the text when the 'Enable' property is set to 'off'.  A simple line of code.

I'm also not sure what you mean by 'disabled'?  Doesn't setting 'Enable' to 'off' disable the uicontrol?

Currently I am using Java to get around this problem.

Thanks for the help.  If you have any suggestions, let me know.

Write a two-line function to do this.

function disableUicontrolAndChangeColor(uicontrolHandle, desiredColor)
set(uicontrolHandle, 'Enable', 'off', 'Color', desiredColor);

Call this function in your code whenever you need to disable a uicontrol and
change its color. You can write a similar two-line
enableUicontrolAndChangeColor function to reverse the process. You can, of
course, make this more elaborate: some things you might want it to do
include having disableUicontrolAndChangeColor return the color prior to
disabling the uicontrol, or return an onCleanup object that restores the
previous color when deleted, or ...

Thanks, but there is no property 'Color' for uicontrols.  Also, setting 'ForegroundColor' does not work.  I am using R2011b.  Maybe changes there were changes made to the properties of uicontrols?

h = uicontrol('Style','text','String','a');
set(h,'Enable','off','ForegroundColor','k')

Running the above code does not change the font color.

Thanks for the help though.

Sorry, I was mixing up inactive and off, and wrongly calling inactive disabled. Whew. Maybe this will work for you though:

h = uicontrol('Style','text','String','a');
set(h,'Enable','inactive','ForegroundColor','c')

Using inactive instead of off lets you still change its appearance...

'[OFF]' as in 'offensive'???
Hi, given that 'off-topicness' is indicated as '[OT]' and taking a look at those postings that started the threads indicated as '[OFF]' (which may both be seen as being somewhat offensive) may lead to the conclusion that '[OFF]' stands for offensiveness. I don't think that this is the intended meaning so what actually *does* '[OFF]' mean? I never came across that abbreviation before (although I have been around on the USENET for quite some time) but maybe it is worth knowing?

replacement for '{' and '}' ?
I am still playing around with what kind of syntax I would like to mark up my documents. Are there equivalent long substitutes for { and } when they are not used to describe arguments to functions? Something like \begin{group} and \end{group}. In other words, if I could force myself to write, say, \begin{group} \it ... \end{group} instead of {\it ... }, then I believe I could identify from the markup context what is an argument that belongs to a just invoked macro and what is text. {Of course, in this context, \textit{...} would be better.} No more ambiguity whether a in \myfunction{a} is an argument or just text. Is there a way to make latex barf when it sees an ordinary '{' in text, rather than \begin{group}, but not barf when I want it (to denote macro arguments)?

Having this description column in a table "Cookies, peanut butter sandwich, regular" When using this WHERE clause: WHERE (((Food_Data.Description) Like "*Butter*" & "*Peanut*")); I dont get any results, however when using it this way round WHERE (((Food_Data.Description) Like "*Peanut*" & "*Butter*")); I get the row as expected. I assume that the query looks for them in order. Is there a way i can get around this and make the query search for both keywords no matter which order i ype them in.

The query looks for a string that matches the pattern "*Peanut**Butter*", so obviously it's not going to match "Butter Peanut".

(patch for Bash) 'vcat', 'vset', 'vfile'
These 3 builtin commands are designed to "dump" and "reload" shell variables to/from file, without going through another layer of interpretation or parsing. In addition to reading/writing simple string for ordinary shell variable, the commands can handle positional parameters and array variables (both index and values). vcat [-0A] [name] > file Writes a shell variable NAME to stdout (inverse of 'vset'). If NAME is missing, then positional parameters are printed. Each value of array elements and positional parameters is terminated by '\0', whereas ordinary shell variable is not \0-terminated unless option -0 is given. By default, only the array values are printed, but option -A will print the array index as well. vset [-0A] [name] < file Assigns a shell variable NAME from stdin (inverse of 'vcat'). If NAME is missing, then positional parameters are set. If input data contains '\0', then it is considered array, and NAME will be converted to array variable. By default, only array values are set, but option -A will set the array index as well. If there is only one string with trailing '\0', then option -0 will set it to regular shell variable. vfile -[rw] [-d dir] [-0A] name... Read (-r) or write (-w) shell variables from/to files of the same name. Internally, it uses 'vcat' and 'vset', so full array content is preserved. vcat [-0A] name > name vset [...

Scilab's 'optim' and 'splin'
I've got this really cool application that makes a smoothed line using splines, then fits it to a source line using a nonlinear weighting. I'm currently using SciLab with it's 'optim' and 'splin' function to do this, but now I need to write some embeddable C++ code. The 'splin' function is obvious -- it generates a spline from a number of inflection points. The 'optim' function as I am using it uses a quasi-Newton method, which is working just fine for me. Before I go and write this stuff up by hand, does anyone have any suggestions on where I can find example code to do this? I'm mostly concerned with the optimization -- I'd like to get my hands on something where some one else has already fallen into the pitfalls.

Python 'for' as Scheme 'let'
We show that the 'for' operator of Python quite unexpectedly can be represented by a 'let' form of Scheme. What looks in Python like for k in range(1,4): print k looks in Scheme as (breset r (let ((k (range r 1 4))) (display k) (newline) )) This iteration construct uncannily resembles Python. It nests and supports the premature termination and skipping of iterations at any level. We should also emphasize that no intermediate lists are constructed! The 'let' in the above code is the ordinary Scheme let. The macro range has been described in the article: http://google.com/groups?selm=7eb8ac3e.0312172046.6d817907%40posting.google.com The macro range was actually designed to emulate 'range' of Matlab and Octave. The fact it turns out so useful to emulate Python loops was a pleasant surprise. All the code in this article should be considered a continuation of that in the quoted article. It is tested on Petite Chez Scheme, Gauche, Bigloo, Scheme48, and SCM. When we run (breset r (let ((k (range r 1 4))) (display k) (newline) )) we see the numbers 1 through 4 printed (in Matlab/Octave and our range, the range is inclusive). We can do more complex things: (breset r (let* ((k (range r 1 3 9)) (j (+ 10 k))) (display j) (newline) )) which prints the numbers 11, 14, and 17 We can terminate iterations early: (breset out (breset r (let ((k (range r 1 4))) (display k) (newline) (if (> k 2) (...

What is wrong with: str_replace('\\', '\', $content); Hi all I have text area, where I can edit files - but I have to correct the returned data, for that I use$content=str_replace('\"', '"', $content); and$content=str_replace('\\', '\', $content); by some reason the latter one causes an error: syntax error, unexpected T_VARIABLE in.... Replacing :-) it by$content=str_replace("\\\\", "\\", $content); and it works what is wrong with '\\' ?

Increment with '#' and decrement with 'b'
Although I've had a lot of practice writing Perl I often feel that I'm not really a Perl programmer because the finer points of Perl style -- the things that really make Perl what it is -- aren't in the front of my mind. I would like help with a simple task which, try though I might, still looks really laborious the way I've written it. I'm turning a standard musical notation for a note into a pitch. The note "A" will be zero, and the other notes on the piano, black and white, will range from 1 (for B flat/A sharp) up to 11 (for A flat/G sharp). A "b" suffix reduces the pitch by 1; "bb" by two. Going the other way, a "#" suffix increases by 1 and "##" by two. So D is pitch 5, Dbb is 3. Equally D## would be 7. So I need to match the following strings to the pitches shown 0 A, Bbb, G## 1 A#, Bb 2 A##, B, Cb ... and so on I can write code lots of ways to do this, but it has no style: it looks like over-cooked potato dumplings, and there's little point in my posting it here. I can extract the basic pitch of the note reasonably elegantly with a hash, like this my %pitches = ( A=>0, B=>2, C=>3, D=>5 ... etc), followed by my $this_pitch =$pitches{ $this_letter }; But every time I try to allow for the accidentals I end up with tedious "if" statements, or multiple increments/decrements like this$self->{pitch}-- if (lc \$acc) eq 'b'; ...

Debian 'testing' and 'unstable'
In a previous post I think I got the functions of the testing and unstable branches of Debian arse-backwards.

If so, sorry for any confusion, folks. Does it really matter? Debian is antiquated, unstable garbage. No wonder it's free.
