Coding Problem edit
I was writing a program for my own purposes, called RF (or Rename Files Files v0.61a), and I ran into a common type of mistake I've been making frequently.What did I do wrong? Good question. I wrote (what I thought) was a simple line of buttons, within a frame. I thought it would be easy to put some on the left, the middle, and the right. It turned out harder than I thought. Here's what it looked like:
What did you do wrong? edit
Well there are lots of options, in fact, tons of options under buttons and pack. I was looking for the option I wanted, found a candidate, and added it. It did not work, because I'd picked the wrong option.So I went back to the documentation, found another option, and tried it too.What I should have done, is REMOVED the option I just added, that did not work.It is a bad thing to have too many options, that don't do anything for you.If you look at the code below, you'll see how I did try adding it to the other buttons also, hoping that that would work. Worse idea!It seems way to simple, when it's done properly, although it may take a while to find the option, for which, you are looking.So I just made a new rule for myself.
Go ahead and try an option, it kind of fun to see what happens with it. Try adding it to multiple items.
But when you've found that you don't like an option you've tried, remember all the place you put it in, and at least comment it out, or perhaps better, remove it.
I hope this situation, and my explanation, helps others. What did my code look like? It looked like this:proc ren_files { } {
#-----------------------------------------------------------------
# ren_files - allows you to rename a group of filenames (no extenstions)
# and you get to use regexp to rename them (and un-rename them)
