Widgets: what's been removed between 5.5.1 and 5.12.2?

[Rob2n]

I'm upgrading a large Windows desktop application from Qt 5.5.1 to 5.12.2. In order to estimate my effort in advance, how can I determine which classes/methods have been removed from Widgets [and not simply deprecated]? I know Qt WebKit is one, but is there a list?

Hi and welcome to devnet,

QtWebKit is a module. The QtWidgets module hasn't lost any classes.

You can find everything in the release logs.

@Rob2n said in Widgets: what's been removed between 5.5.1 and 5.12.2?:

which classes/methods have been removed from Widgets

None of them.

Qt promises source and binary compatibility across minor releases. No class/method is allowed to be removed from a module (including Qt Widgets) until Qt 6.

is there a list?

Like @SGaist said, the release notes are the official authoritative source. For convenience, you can see:

• https://wiki.qt.io/New_Features_in_Qt_5.6
• https://wiki.qt.io/New_Features_in_Qt_5.7
• https://wiki.qt.io/New_Features_in_Qt_5.8
• (... etc.)

Look for the "Removed Modules" headings to find out which modules have been removed.

@sgaist Thanks for that distinction.

@jksh Thanks for the links. They are what I needed.
