“ QTextEdit”对象没有属性“ setPlaceholderText”

Question

I know that this question has been asked before , but there only PySide was referred as alternative. I kind of want it to work using PyQt4 .

The problem is simple: I am using QtDesigner to create a .ui file. In the QtDesigner preview the PlaceholderText in my QTextEdit works just fine. In my python program however I get this error:

'QTextEdit' object has no attribute 'setPlaceholderText'

which is not true, at least according to the Qt Documentation . The feature was added in version 5.2 and I am using 5.6 . PyQt4 s version is 4.11.4 (up to date). My python version is 3.4 . Any idea why it is not working?

Edit: I am open to alternatives involving using another object instead of QTextEdit , but I do not want to switch to PySide .

Answer 1

您使用的PyQt4尚未针对Qt5构建 ，因此它无法访问Qt5中添加的任何功能。
