Hi, just updated to Qt Creator 17 and it looks good, however when rebuilding
my Qt Creator plugin I got stuck for a bit with this failing:
auto pe =
qobject_cast<QPlainTextEdit*>(EditorManager::currentEditor()->widget());
For almost 15 years that statement served me well and it allowed for example
setting a fatter cursor at Qt Creator start (useful on 4K screens) but
today, it returns a nullptr :-(
Instead, the new incantation for Qt Creator 17 (and onwards?) seems to be:
auto pe =
qobject_cast<Utils::PlainTextEdit*>(EditorManager::currentEditor()->widget());
After that fix, it's smooth sailing (Utils::PlainTextEdit behaves 100%
compatible with QPlainTextEdit).
But if there was a bit of documentation of this new class in the Utils::
Namespace I would be even more happy!
Sorry to hear that this bit you.
I guess nobody expected that some plugin out there had a hard dependency
on Editor::widget() being in fact a QPlainTextEdit for text editors.
The fact that Utils::PlainTextEdit behaves like QPlainTextEdit is not
quite an accident, the idea is add a few features and try to upstream
it to Qt proper again. For this to happen it has to stay compatible.
In case this upstreaming will be successful there's a good chance that
Utils::PlainTextEdit will vanish again. But then there'll hopefully
be a more communication.
Thanks for answering, it's all working fine now with the new
Utils::PlainTextEdit.
Perhaps I'm doing it wrong, i.e. I shouldn't take a hard dependency on
the built-in editor being of a certain class.
Say I were to write a new plugin to Qt Creator having only one command,
like F5 in Notepad in Windows: inserting the current date and time where
the text cursor is.
What would the best approach be? (Utils::MacroExpander could probably be
good enough for inserting the date but what about the time.)
