|
||
|

\fBtkwait variable \fIname\fR

.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
The \fBtkwait\fR command waits for one of several things to happen,
|
||
|
|
then it returns without taking any other actions.
|
||
|
|
The return value is always an empty string.
|
||
|
|
If the first argument is \fBvariable\fR (or any abbreviation of
|
||
|
|
it) then the second argument is the name of a global variable and the
|
||
|
|
command waits for that variable to be modified.
|
||
|
|
If the first argument is \fBvisibility\fR (or any abbreviation
|
||
|
|
.VS
|
||
|
|
of it) then the second argument is the name of a window and the
|
||
|
|
\fBtkwait\fR command waits for a change in its
|
||
|
|
visibility state (as indicated by the arrival of a VisibilityNotify
|
||
|
|
event). This form is typically used to wait for a newly-created
|
||
|
|
window to appear on the screen before taking some action.
|
||
|
|
.VE
|
||
|
|
If the first argument is \fBwindow\fR (or any abbreviation
|
||
|
|
of it) then the second argument is the name of a window and the
|
||
|
|
\fBtkwait\fR command waits for that window to be destroyed.
|
||
|
|
This form is typically used to wait for a user to finish interacting
|
||
|
|
with a dialog box before using the result of that interaction.
|
||
|
|
.PP
|
||
|
|
While the \fBtkwait\fR command is waiting it processes events in
|
||
|
|
the normal fashion, so the application will continue to respond
|
||
|
|
to user interactions.
