But it also forcibly expands over multiple lines: Red background was added to emphasize the dimensions of the QTextEdit . Desired size is the size of one text line.

qtextedit - resize to fit

由 旧巷老猫 提交于 2020-01-22 13:34:13
问题 I have a QTextEdit which act as "displayer" (editable to false). The text it displays is wordwrapped.

Basically the widget (in the same vertical layout) below the layout should get as much space as possible. How can this be achieved most easily? 回答1: I found a pretty stable, easy solution using QFontMetrics ! from PyQt4 import QtGui text = ("The answer is QFontMetrics\n." "

问题 I am trying to build an application that would display rich text documents in paginated fashion - more or less like MS Word does. For now, I would like to have only one page displayed at a time. From this question I have learned that I need to represent the document by QTextDocument. While the author of the question focuses more on the view representation, I would like to learn about accessing document data in paginated fashion. I can see that the class has methods such as setPageSize() and
