I am trying to create a simple text window which I can just write text to.
I don't have a file, but the docs say that if you don't specify XtNfile
it will use tmpnam(). Well, it does, except that it then tries to open
the file with a r+ option which doesn't work because the file doesn't
exsist. Short of creating my own tmpnam() opening it and closing it to
make it exist and passing that, is there a way around this. Is this
a bug, or am I doing something wrong??

> I am trying to create a simple text window which I can just write text to. It sounds like you need an asciiString widget. Who is doing the writing? If the user is typing at it then you probabally want an editable text widget, and this is not supported by the asciiDisk widget in R3. In R3 you need to allocate enough space for the user to type into, and then pass this buffer into the Text widget with the XtNstring resource, and the length of this buffer with the XtNlength resource. If the application just wants to display a multi-line string then you should need an asciiString widget anyway.

Why would you want a read only text widget on a file that doesn't exist? > Is this a bug, or am I doing something wrong?? The fact that this is so difficult to understand the interface, and that you have to do so much work to get a simple text widget up and running is a bug. The R4 interface will go a long way to improving the Text widgtet's API. Chris D. Peterson MIT X Consortium Net: kit@expo.lcs.mit.edu Phone: (617) 253 - 9608 Address: MIT - Room NE43-213
