Troubleshoot with QTextEdit

Matzomatzomatzo

Hello world!

I got this troubleshoot code in constructer:
ui->QtexteditObj->setAlignment(Qt::AlignRight)

This code doesn't work for me if i'm create QTextEdit's object in qt designer,in other ways it's work

Can anyone tell me the solution?)

Hi and welcome
Make 100% sure u call it after
ui->setupUi(this);
as it constructs what u used in Designer.

If thats already the case, then i assume
"in other ways it's work" means that if u do it from a button with text selected, - it works?

It sets the alignment of the current paragraph, so u might need to select something first

wouldn't result the otherway around in a crash? ;)

@Matzomatzomatzo
when is ui->QtexteditObj->setAlignment(Qt::AlignRight) called?
What other calls to the textedit do you have before/after this line?

Hi
Yeah it should/does,
but crash is also sometimes covered by "doesn't work" ;)
But yes, should have said "silly question, but xx"

i solve this problem, but dont get why it should be like that

So if i'm add code like this

ui->QtexteditObj->setAlignment(Qt::AlignRight);
qDebug() << ui->QtexteditObj->alignment(); // here Align is Right
ui->QtexteditObj->setText("Type text here"); // but after this code Align is Left
qDebug() << ui->QtexteditObj->alignment();

it doesnt work align after setText

ui->QtexteditObj->setText("Type text here");
ui->QtexteditObj->setAlignment(Qt::AlignRight);
qDebug() << ui->QtexteditObj->alignment(); // here Align is Right

it's work like should

Hi

if setAlignment sets the alignment for a paragraph of text
(see doc)

When you do
ui->QtexteditObj->setText

I think it replaces the paragraph with a new one since u replace all text
and the default alignment is left for that new paragraph

Just guessing. Did not test it :)
