I have created a minimal example on www.classintouch.de/TextEditBug.zip - but all you need for reproducing is actually just any QTextBox out of the... ahem... box. This is quite obviously linked to https://bugs.kde.org/show_bug.cgi?id=307748, as all those symptoms are *gone* when predictive Text is switched off. I have not marked it a duplicate, because it is a different QWidget and so it might happen, that we "remove the cause but not the symptom" :-) I get this issue as well using the stock android keyboard on a nexus7 with android 4.2.1. I can confirm this issue on a Nexus 10 with android 4.2.1 and stock keyboard. Is it possible to disable predictive Text for Necessitas programmatically to work around this bug? *** This bug has been confirmed by popular vote. *** @Taiko: Yes, it is possible to programmatically disable predictive text entries. I don't know a way to do that globally, but you can do it on a per-widget basis (or by subclassing those widgets and use those subclasses throughout the program, if you prefer). Example code: QLineEdit* lineEdit; Qt::InputMethodHints currentHints=lineEdit->inputMethodHints(); lineEdit->setInputMethodHints(currentHints|Qt::ImhNoPredictiveText); This workaround avoids all other "predictive text" related problems, too, of course. Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years and I will be closing this bug. |
[ENTER]: If you press <enter> after typing in a *single* word, the next keypress will duplicate this last word into the next line (now: the current line) , the pressed key's character is appended. If you don't enter a single word but use a space somewhere in middle or at the end of the line, you get the expected behaviour, while the bug is still present when the only space is the *first* character of the line. Typing [a],[enter],[b],[enter],[c],[enter] will result in a ab abc --> The behaviour is 100% reproducible on 4.2.1, it does *not* appear on 2.3.4. [BACKSPACE] In a QTextEdit the "backspace" is behaving quite erratic. When the backspace cursor reaches the trailing space of a word (say "foo ") this word is being duplicated ("foofoo"). The next backspaces will erase the last foo: "foofo", "foof" "foo" while the following wil result in a partial duplication: "foofo". The whole process as an overview: foo foofoo foofo foof foo fofo fof fo ff f --> The behaviour is also 100% reproducible on 4.2.1, it does *not* appear on 2.3.4. Reproducible: Always Steps to Reproduce: [ENTER]: 1. Create a QTextEdit 2. Type "Hello" into it 3. Press [enter] 4. Enter "world" [BACKSPACE]: 1. Create a QTextEdit 2. Type "Hello" into it 3. Press [enter] 4. Press [backspace] Actual Results: [Enter]: Hello Helloworld [BACKSPACE]: Hello Hell Expected Results: [Enter]: Hello world [BACKSPACE]: Hello I use the current Necessitas (2.5.84) on a Windows XP VM and deploy to Emulator, Samsung Galaxy 2 (Android 2.3.4) and Nexus 10 (Android 4.2.1). The problem occurs only on the Nexus.
