  • Hello, ~amir734jj

    I looked into your source code and it's not cool.

    Your problem lies in setBold() of mainwindow.cpp:129
    @
    textEdit->setFont(newFont);
    @

    You are sayin' that it doesn't apply changes for selected text, but it shouldn't. It sets style for the whole text!

    I would advice you to find another workaround here, ok?

    :D



  • What do you mean by workaround ?

    Sorry I am not a native English speaker !



  • C'mon, man! There is google for these things! http://en.wikipedia.org/wiki/Workaround

    try this (not actively tried though):
    @
    QTextCursor cursor = textEdit->textCursor();
    QFont boldFont(textEdit->font());
    boldFont.setBold(true);
    QTextCharFormat format;
    format.setFont(boldFont);
    cursor.setBlockCharFormat(format);
    @

    It's not enough though :) Final code is going to be:
    @
    QTextCursor cursor = textEdit->textCursor();
    QFont boldFont(textEdit->font());
    boldFont.setBold(true);
    QTextCharFormat format;
    format.setFont(boldFont);
    cursor.setBlockCharFormat(format);
    textEdit->setCursor(cursor); // maybe &cursor :)

    Sorry, use this one instead: http://qt-project.org/doc/qt-4.8/qtextedit.html#setTextCursor

    And why can't people not copy-paste but think, think a bit?
