Ruby/Tk

Now I seldom uses Tcl/Tk. Ruby/Tk is interesting, useful and powerful!

Class

tkgetfile.rb

In tkgetfile.rb, there defined three classes; two of them are TkGetopenfile and TkGetsavefile which are wrappers of Tk commands tk_getOpenFile and tk_getSaveFile, respectively, and the other is TkGetfile class which is a super class of TkGetopenfile and TkGetsavefile. Like TkDialog class defined in tkdialog.rb, you can get a file name for open and save easily by TkGetopenfile and TkGetsavefile.

You may know the detailed usage of these classes when you read tkgetfile.rb :-). If you want to know the meanings of options, please read "man pages" of tk_getOpenFile.

When I made these classes, I didn't know that there were Tk.getOpenFile and Tk.getSaveFile in tk.rb (^^;. These methods require "Tcl list" as file patterns, however, my classes understand "Ruby array".

tkchoosecolor.rb

TkChoosecolor class which is a wrapper of a Tk command tk_chooseColor is defined. Like a TkGetOpenfile class mentioned above, I did not know Tk.chooseColor when I made this class :-).

It would be better for a "Color chooser" script to handle not only RGB, but HSB as a Tk demo script tcolor distributed with Tk.

tkpopup.rb

TkPopup class which is a wrapper of a Tk command tk_popup is defined. You can post a popup menu easily by specifying a TkMenu object.

tkmessagebox.rb

TkMessagebox class which is a wrapper of a Tk command tk_messageBox is defined. Some kinds of dialog boxes are defined alreadly, and it is easier to use them than TkDialog.

Application

moc.rb

This is "MOuse Cursor viewer", where you can see the names and shapes of a mouse cursor defined (?) in X. The names of a mouse cursor are written on buttons (to tell the truth, these are raised labels, though). When you put a mouse cursor on a button, the shape of a cursor change.

Before using moc.rb, please specify the locations of Ruby interpreter in 1st line and cursorfont.h in 10th line.
