Say I have a text document. I have a line.I want to delete the text on that line and replace it with another text. How do I do this? There is nothing for this on the docs, thanks in advance!

推荐答案

要替换QScintilla中的一行，您需要先选择该行，如下所示:

To replace a line in QScintilla, you need to first select the line, like this:

    # as an example, get the current line
    line, pos = editor.getCursorPosition()
    # then select it
    editor.setSelection(line, 0, line, editor.lineLength(line))

选中该行后，您可以将其替换为:

Once the line is selected, you can replace it with:

    editor.replaceSelectedText(text)

如果要用另一行替换该行(将在此过程中将其删除):

If you want to replace a line with another line (which will be removed in the process):

    # get the text of the other line
    text = editor.text(line)
    # select it, so it can be removed
    editor.setSelection(line, 0, line, editor.lineLength(line))
    # remove it
    editor.removeSelectedText()
    # now select the target line and replace its text
    editor.setSelection(target, 0, target, editor.lineLength(target))
    editor.replaceSelectedText(text)
