how to set text alignmet to right ?

[mismael85]

hi,
i want to align the text to the right in a QTextEdit
i tryed the following code but it failed

mainText->setAlignment(Qt::AlignRight);

mainText->setAlignment(Qt::AlignRight);

To copy to clipboard, switch view to plain text mode 

i also want to show a tree elements from right to left
i build QTreeWidget and i successed to fill it with items
but the tree nodes appeares from left i want them from right
please help me.
and thank you

The Alignment is a Paragraph Propertiy then QtextEdit::setAlignment set Alignment of the current Paragrah
Try with

QTextOption options = mainText->document()->defaultTextOption();
options.setAlignment(Qt::AlignRight);
mainText->document()->setDefaultTextOption(options);

QTextOption options = mainText->document()->defaultTextOption();
options.setAlignment(Qt::AlignRight);
mainText->document()->setDefaultTextOption(options);

To copy to clipboard, switch view to plain text mode 

For TreeWidget you have to use QTreeWidgetItem::setTextAlignment() for all items in the tree.

QApplication::setLayoutDirection(Qt::RightToLeft);

QApplication::setLayoutDirection(Qt::RightToLeft);

This affects all visible text on Application (menu, Title Bar, ...).
I don't think mismael85 needs this

Well, he said that he wants tree nodes to appear from right to left. Adjusting alignment doesn't affect tree nodes. Of course one can also change the layout direction of a single widget with QWidget::setLayoutDirection(), but does it make sense if the layout direction of the rest of the application is different? To me it sounds like a quite confusing UI design at least.

You are right.
I hope that mismael85 intends set Text Alignment.

thank you all every thing works fine now.
first for the text alignment int the QTextEdit i wrote the following code and the result was
perfect

QTextOption options = mainText->document()->defaultTextOption();
    options.setAlignment(Qt::AlignRight);
    mainText->document()->setDefaultTextOption(options);

QTextOption options = mainText->document()->defaultTextOption();
    options.setAlignment(Qt::AlignRight);
    mainText->document()->setDefaultTextOption(options);

To copy to clipboard, switch view to plain text mode 

and mcosta was right on this
and for jpn i used your code and it also was nice the tree nodes became from
left to right but it does no thing for the text int the QTextEdit so i used both codes.
thank you all.
