How to tell a window has not been closed?

janeg — Wed, 05 Sep 2012 14:42:31 GMT

Can someone tell me if there is an easier way to tell if a window is still open? I have a case where a task is being done. Once it is done, the window is closed. However, the user can close the window before then.

I can't find the jsl command that equals Is Valid

window_ptr = New Window( "hi", Text Box( "abcd" ) );

window_title = (window_ptr << Get Window Title());

Wait( 5 );

windows = Window();

window_open = 1;

For( i = 1, i <= N Items( windows ), i++,

tmp_title = (windows << get window title);

If( window_title == tmp_title,

window_open = 0

);

If( window_open == 1,

Print( " window is closed." ),

Print( " window is open." )

);

Here is one way to avoid the loop:

if(window(window_title)=={}, Print( " window is closed." ),

Print( " window is open." ));

I just found another way to do the same thing. Use is empty() on the window variable. If it's true, then the window is not open. If it's false, then it is open.

window_ptr = New Window( "hi", Text Box( "abcd" ) );

Wait( 5 );

window_open = !Is Empty( window_ptr );

If( window_open,

Print( " window is open." ),

Print( " window is closed." )

);
