From a0313c85a9b8ab6ba0ec273f0c8638e2f7b8cc18 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Tor=20Arne=20Vestb=C3=B8?= Date: Wed, 8 Mar 2023 10:27:48 +0100 Subject: [PATCH] Plumb QMessageBox::setCheckBox() through QPlatformMessageDialogHelper Without this plumbing we have no way of knowing if the QMessageBox has a checkbox set, and can't decide to skip the native dialog, leaving the user without the expected checkbox. As the suppression checkbox on macOS can be customized, we can use this plumbing to actually provide native dialog support for generic check boxes. This mechanism can also be used by QErrorMessage, which now matches behavior between native and non-native dialogs in terms of the label of the checkbox and its initial state. We might want to tweak this in the future, since user's might expect the suppression label and state to match the system default, but that's something we can expose from the platform theme if so, and should apply equally to the non-native dialog.
