This file outlines the commands that are available in
the eventutils package.

--------------------------------------------------

close_toplevel { widget }

This command will close the toplevel window given
as the widget argument.

Example: Query for next toplevel and then close it.

set top [next_toplevel]
close_toplevel $top

--------------------------------------------------

mouse_click { widget args }

This command uses the "event generate" command
to simulate a user clicking the mouse over
the given widget. Optional arguments can include
any valid options to the "event generate" command,
the most common of which are -x and -y to indicate
the x and y coords of the mouse click.

Example:

set top [next_toplevel]
set button $top.open
mouse_click $button

--------------------------------------------------

mouse_double_click { widget args }

This command works just like mouse_click except
that it generates a double click event instead
of a regular click.

FIXME: Do we need a mouse_triple_click ?

--------------------------------------------------

pause {{msecs 1000}}

This command will pause the execution of the
script for a given number of (1/1000) second
intervals. This can be useful in cases where
you know that some amount of delay is needed.
If invoked with no arguments, it will pause
for one second.

Example: Pause script for 5 seconds, then destroy

set top [next_toplevel]

pause 5000

close_toplevel $top

--------------------------------------------------

writefile { file data }

This command will write the given buffer of data
to the file named "file". This command is
typically used to create files that will be
loaded into a project or some such thing.
If the file already exists it will be truncated.
The directory where the file will live must
already exist.

Example: Create some source files in /tmp/foo

file delete -force /tmp/foo
file mkdir /tmp/foo
writefile /tmp/foo/f1.c {int func1(int i) { return 0; }}
writefile /tmp/foo/f2.c {int func2(int i) { return func1(0); }}

--------------------------------------------------

enter_text { widget text }

This command is used to enter text into a widget.
The exact way that text is entered depends on the
widget in question. In general, one can assume
that text that was already in the widget gets
erased before new text is added.

Example: Enter some text into an Entry widget

set top [next_toplevel]
set entry $top.entry

enter_text $entry HELLO

--------------------------------------------------

listbox_select_index { lb index }

This command will select a numerical index
in a listbox widget. If the numerical index
is bigger than the number of elements, then
an error will be raised. The mouse_click
command is used behind the scenes to actually
select the index, so as to simulate the user
actually clicking on the given index in the list.

Example: Highlight the first element in the listbox

set top [next_toplevel]
set lb $top.listbox

listbox_select_index $lb 0

--------------------------------------------------

listbox_select_entry_pattern {lb pattern}

This command works like the listbox_select_index
command except that instead of providing a
numerical index, one would provide a pattern
that matches the item in the listbox that
you would like to select.

Example: Highlight an entry that matched Foo*

set top [next_toplevel]
set lb $top.listbox

listbox_select_entry_pattern $lb Foo*

--------------------------------------------------
