If we create a textbox and press any keystroke while executing the program. It will crash. WHY?! Widgetmodule.tu comes up and highlights the error. omg, I want it so that if you press any keystroke, it wont crash!

what's the code and error message in Widgetmodule.tu ?

Yeah, this one pops up every now and again. If I recall correctly this is a problem with the GUI module itself and not really something you'll want to try and fix. Unless you really want to wade through the Widget module! I think Cervantes came up with a solution to this a while back, or did he just create a new one altogether. There's an idea! (Albeit one that I frequently suggest). Turing's GUI sucks, with a capital 'H'. Make your own GUI if you need it, it will be more compact, more efficient, more tailored to your own needs, and will result in a smaller file size.

I just commented a line in the widgetmodule.tu and the error doesn't appear but I know it will occur someplace else because thats the reason they put the line there lol Anyways, If I edit "my" widgetmodule and then compile my file in exe and distribute, will it cause an error in the other person's computer?

Once you compile the .exe, it's no longer running via Turing. Changing your predefs or GUI libraries will not affect them on other computers when running your .exe. You still haven't answered Tony's question, by the way, which will make it easier for us to help you.

Line 104: Deferred subroutine has not been resolved.

Author:	Cervantes [ Sat Jan 14, 2006 6:05 pm ]
Post subject:
What's the subroutine? (What's the procedure/function called?) What happens if you try to resolve it with an empty procedure (or perhaps a function that returns 0, false, or a null string, depending on what it's looking for)?

Why dont you try the code I posted above and run it and press a key... You can understand it way better than me :S

Author:	Cervantes [ Sat Jan 14, 2006 11:25 pm ]
Post subject:
Because I don't have the linux version of Turing, and WINEing it would probably cause it to crash before the error you're describing occurs.

So could someone else do it? Because if I comment the line, I want to make sure that it doesnt interfere anywhere else, or what I will do is comment the line, save it, compile exe and uncomment it again, that way everything stays perfect

ohh I think I figured it out, it disables the keystrokes made by the user if I comment that line. For eg: I have a widget that is set as default (true) so when I press enter it activates, now If I comment that line, I am able to get rid of the error but the keys become useless but I guess I will do it for that program only because I dont think I need keystrokes anywhere else in the program... Suggestions?

Declare your text fields first, fixed it for me.

Oh I get it, if you declare the box before you change any properties of the window, the keystrokes wont give an error, but if your program does require to change windows, we have to do it my way....

So the GUI.CreateTextBoxFull widget is uneditible? I was hoping to make a word processor.
