Windows XP and NT

This install was tested with ActiveState's free ActiveTcl distribution release: ActiveTcl 8.4.12

  • Download and install Visual Tcl from the projet download page, you should grab the newest release.
  • My file was named: tcl-1.6.0.tar.gz
  • Unpack the file. In my case, I used WinZip to extract to: c:\
  • Rename c:\vtcl-1.6.0 to c:\vtcl
  • Go into your vtcl directory and double-click on "vtcl.tcl" icon.

Windows 95

  • Unzip Visual Tcl into a permanent location. A good default s "C:\vtcl"
  • If you wish to create "shortcuts" to the vt.tcl icon, make sure you edit the "startup directory" to the base installation directory for Visual Tcl.
  • You will need to associate all ".tcl" files with the Wish appplication.
  • Double-click on "vt.tcl" icon.

Hints and Tips

  • To attach a scrollbar to a scrollable widget (listbox, text, etc), first select the scrollbar with a single left click then shift-click the target widget.
  • If performance seems a bit slow, kill the Attribute Editor window. You can always bring it back later from the "Window" menu.
  • Right-clicking gives you the "Option" menu.
  • Try using the arrow keys to move widgets in the place or grid layouts. Use the shift key + arrow keys to resize widgets.
  • To control whether a toplevel can be resized, click on the "width" and "height" labels in the Geometry Info window when "Window" is selected.
  • Tcl/Tk's performance on Win95 is not exceptional. NT4.0 seems to have a 5x improvement in GUI speed.
  • For users of Fvwm95, a mini-icon for Visual Tcl is in the images directory named "mini-vtcl.xpm"
