Want to change selected text's font put I can't

[amir734jj]

I am writing a text editor and I got a serious problem
When I click on Bold , it Bolds everything not the selected text
There is the same problem when I click on Italisize or small, normal, large

Any idea would be appreciated

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?
