any chance to get a working version ?
i cannot copy&paste&run your snippet with v4

Posted: **Fri Jul 21, 2006 2:40 am**

Here's my original code converted to PB4. You will still need to check clipboard contents and enable/disable menu items as desired.

Code: Select all

Thank you for all the great information on this topic.

I am multi-platform (Mac and PC) programmer and need to find a simple solution to put the line numbers on the left side of my EditorGadget, just like the PB program does. I see Windows solutions, but nothing for Mac. Please help.

Also, the original code by Sparkle (above) runs but then freezes after the compiled window shows up. I'm using the most recent PB on a Mac OS X 10.9

You might consider Scintilla--it has line numbers built in.

DirkVW,
As you seem to be new around here:
PureBasic has a built-in Scintilla gadget.
Works on Windows/MacOS/Linux
Enjoy!
