Different colours on different characters in a entry widget

Is it possible to set the colour of _one_ character different from the rest in a entry widget? I tried to use set_style before the character was appended, but then the whole text changed to the colour I had specified. -- Preben Randhol -- [[EMAIL PROTECTED]] --

Re: GTK+ 1.2.8 doesn't seem to work.

Hi Mikas, Looks like you need to install Xt, and probably some other things e.g. X11. Yes I know this is a bitch, I am having problems with various libs myself. You already run X, right? e.g. I have lots of files /usr/X11R6/lib/libXt* Simon. ___ gtk-l

GTK+ 1.2.8 doesn't seem to work.

Hi, There seems to be one little problem, that prevents dumb users like me from using GTK+ (and all the other programs that require it) So it's like this: I've installed glib1.2.8 then launched GTK+1.2.8's "configure" file and got an error message saying that I don't have some X Libraries or Inclu

Xlib-error in threaded GTK+

I've read the FAQ, and I've done what it suggests, but I still can't get rid of the "Xlib: unexpected async reply (sequence 0x)!". I have a program, where I first have a part which uses no GTK+ or X calls at all. In this first part, I create a thread, using pthread_create(). This thread runs

Re: Using gtk_timeout_add with very short timeperiods (45 ms)

I am not quite sure about what your problem is, maybe you need to send some codes. But you maybe want to check: 1. the function that you made for the time out call back, whether you set the return value to 0. You must set the return value to 1 so that the call back function will be called aga

Using gtk_timeout_add with very short timeperiods (45 ms)

I'm trying to write a program that reads a hardware port every 45 ms, it's a CID application with a piece of hardware attached to the parallell port. I tried having a gtk_timeout_add that runs a function every 45 ms, but it doesn't seem to work very well. The Clist I have in the program doesn't g

Re: C question

Bruce is right. You can shoot your foot more than one way. If you are using strncpy and your string printing function is dependent on a null terminated string, you better make sure the string you are copying is null terminated. My point is this, you can always points out the obvious but it'

Re: C question

I guess the problem is about memory usage. You didn't malloc some space for the text. What you should do is : void some_function (...) { item temp; temp.text = g_malloc( SIZE ); strcpy( temp.text, ".." ); add_item(temp); } You cannot simply set a string to a pointer withou

Re: C question

You should consider declaring your structure like that typedef struct a_item{ g_char b[ MAX_G_CHAR_SIZE ]; } A_ITEM; Use strcpy or iits equivalent to copy it. I think that's a good way to do that because g_malloc will that allocate the right size for you. Your code did not allocate space for

Having linker problems.

Hi there, I just typed in the program that is in the book developing linux applications with GTK+ and GDK. I'm getting undefined linker errors for the functions g_set_error_handler, g_whatever_handler (s). This is the first program on pages 10,11, and 12. I was wondering if you could throw some

Getting the width of widgets

Hi folks, Reading the gtk source code is not helping me solve my current problem! I've got a hbox with a clist and vseperator in it. What I'd like to do is find out the width of the clist and the seperator so I can generate a pixmap to fit the remaing space. The clist can be empty, but it has a
