I’m using a WindowDialog to display story event text and options to the player, and I don’t want the window to have an exit button in the upper right. The player has to select an option, they can’t just dismiss the dialog.

Is there a way to remove the exit button so I can have full control over when the WindowDialog is allowed to close?

Looks like you can get a reference to the close button and then hide or remove it. So, something like this…

var btn = $WindowDialog.get_close_button()
btn.visible = false  // hide the button, or...
btn.queue_free()     // ...remove it all together

Works when I use .hide() on the retrieved close button.

Attempting to free it causes a crash.

Hmmm… I tried them both before posting and they seemed to work ok here (in 3.2). Anyway, glad hiding it works.

The engine expects you not to free internal nodes, so hiding them is a better solution indeed.

Ya using queue_free() crashes the program. At least when you hide a button it doesn’t work.
