Hello,
I am new to nedit. It is an excellent editor. I have been using my own
Motif editor for over 10 years. I was attracted nedit's syntax
highlighting and tags support. Nedit is a very intuitive editor.
I would like to make a suggestion. I would like to change the
background colors on the popup menu pushbuttons that I created.
Unfortunately, they are all named "cmd". A small change to userCmds.c
will give each widget its own name, which will allow setting colors via
a X resource file.
The code is below. Basically, it uses the argument 'name' to
createUserMenuItem() to create a name for XtVaCreateWidget(). The new
function, create_widget_name(), will filter non-alpha/non-digit
characters which may cause trouble in a resource file.
Opinions?
