how to change the background color of QLineEdit

[Qt Enthusiast]

I am QLineEdit as disabled , I want to change the background color QLineEdit as a grey

[Eddy]

Try this :

QPalette *palette = new QPalette();
palette->setColor(QPalette::Base,Qt::gray);
ui->lineEdit->setPalette(*palette);

Out of curiosity if our QLineEdit is disabled it should have the look and feel of your OS (in my case = grey) to reflect that. Why would you want to change that?

[Qt Enthusiast]

Is t possible to make the boundary of QLineEdit of same color that of background trying to make boundary of QLineEdit as invisible

[Eddy]

Yes that is possible.

What have you tried already? How is your background set? Please give us some code, preferable a minimal working example so that we can see the context of what you want.

[Qt Enthusiast]

int Count = 100;
QPalette* palette = new IN_CURRENT_POOL QPalette();
palette->setColor(QPalette::Base,QColor(236,236,236));

QLabel* countLabel = new IN_CURRENT_POOL QLabel(tr("Pin count:"));
/QLineEdit* lineEdit = new IN_CURRENT_POOL QLineEdit;
lineEdit->setPalette(*palette);
lineEdit->setText(QString("%1").arg(pinCount));
lineEdit->setReadOnly(true);
countLabel->setBuddy(lineEdit);

Please let me know how to do the same

@Qt-Enthusiast take a look at qt's StyleSheets

that should have everything that you need, according to what you described so far.

As I see the context of what you want to do I would advise to use a QLabel instead of the QLineEdit. You never want to use it as an input field are you?

If you use QLabel you already have the background color without the border

OK, you don't want QLabel because you need copy paste funcitonality. Now I understand.

You can use the following stylesheet on your lineedit :

ui->lineEdit->setStyleSheet("background: transparent;  border: 0px ;");

[Qt Enthusiast]

ui->lineEdit->setStyleSheet("background: transparent; border: 0px ;"); is giving me white color for background , how to set Color with RGB QColor(236,236,236) in below line

ui->lineEdit->setStyleSheet("background: transparent; border: 0px ;");

[Eddy]

ui->lineEdit->setStyleSheet("background-color: rgb(236, 236, 236); border: 0px ;");

Glad you could make it work. Can you please mark this topic as solved and start a new one since this is a totally different question.
Please provide us with the needed code of what you have already and explain as good as possible what you want to do.

Edit : made a new topic for your question : copy from qlineedit using pop up menu
