[Gambas-bugtracker] Bug #2999: gb.form Dialogs trigger FMain Form_Close event when closed; Qt6

[<bugtracker@xxxxxxxxxxxxxx>]

http://gambaswiki.org/bugtracker/edit?object=BUG.2999&from=L21haW4-

T. Lee DAVIDSON reported a new bug.

Summary
-------

gb.form Dialogs trigger FMain Form_Close event when closed; Qt6

Type             : Bug
Priority         : Medium
Gambas version   : 3.20
Product          : QT5 component


Description
-----------

As in the summary except that the issue appears to be only with the Dialogs that involve interaction with the file system. Dialog.SelectColor and Dialog.SelectFont do not behave that way. Also, Using gb.qt5 does not produce the issue. (I do not have gb.gtk* installed.)


P.S. There is no QT6 item in the Product drop-down list.
