Closing the AB Line dialog box with the OS close button not working right

[torriem]

When we close the AB line dialog box with the OS's close window button (red X), the rejected() signal is not generated. Hence the ABLine button remains selected. Not sure what logic is needed to address this. Can do something onVisibleChanged, but has to be aware that the dialog box might already be accepted or rejected, and should not override that.

This issue will affect any place we choose to use the Dialog type

Well, qt6 no longer has that button. So I guess no longer an issue.
