Tiny JSL Challenge: Escape from Modal OnClose(0)

[#1]

in Display number of selected rows in the new window   I gave a solution that uses the <<OnClose(...) function and noted that the script ends with ;1 so the window can actually close. If it ends with ;0 the window will not close, and because it is a modal window, you are

• stuck
• caught between a rock and a hard place
• painted into a corner

Because this example uses Graph Builder and a Data Table, there is a way out (without using Task Manager to kill JMP.)

Can you find it?  Save your work before starting!

Replies here are OK, maybe there is more than one way...spoiler/solution follows.

My solution (different from @Craige_Hales solution):

After some playing around I started thinking that I can most likely manipulate the buttons and use those to close the window. I took fairly easy way out and set following script to OK button

Set Function(Function({this},
	((this << top parent) << On Close(1)
)))

You cannot simply set this by right clicking, but you can right click around and find one Show Properties -> Find the correct button box from the list and then set some simple action to Press

after setting something to the press you can right click on the button and modify script it runs

Then Set Script which will modify the modal windows on close to return always 1, press OK and modal will close

@jthi  solution is better; it only needs the OK button. Thanks!

Out of curiosity: why does OnClose even set this flag, isn't that the purpose of OnValidate?

[#5]

On Validate is tied to the OK button; you can cancel without validating.

On Close is tied to the window preparing to close, for any reason.

You can probably use both, but I'd be hard pressed to come up with a good reason.

At the OS level, https://docs.microsoft.com/en-us/windows/win32/learnwin32/closing-the-window shows there is another interesting hook when the window has disappeared off the display and is about to be destroyed (WM_DESTROY). JMP does not expose this event.
