In the case where native wxNotificationMessage is not available and
wxGenericNotificationMessage is used as wxNotificationMessage, m_impl was
being initialized twice. This happens already in the constructor for
wxGenericNotificationMessage. This was causing a leak of a
wxGenericNotificationMessageImpl and even more problematic, a leak of a
wxFrame, which caused some oddities. So, just remove the initialization from
wxNotificationMessage.
Closes https://github.com/wxWidgets/wxWidgets/pull/2631
No real changes, just clean up sources by removing trailing spaces from
all the non-generated files.
This should hopefully avoid future commits mixing significant changes
with insignificant whitespace ones.
wxNotificationMessage has been refactored to always use wxNotificationMessageImpl (this was previously already done in the MSW implementation)
This adds various features and fixes to wxNotificationMessage:
- OS X Notification Center implementation
- Generic "toast" notifications
- SetIcon() to specify a custom icon
- AddAction() to add actions to notifications
- Events to get notify of notification clicks, dismiss or actions
