How to make a QLineEdit not editable in Windows

Question

I'm using Qt 5.2 and I would like to make a QLineEdit not editable. The problem with this is, that it doesn't appear like it. When using setReadOnly(true) it stays with white background and looks like it is still editable.

If I disable it, then it turns gray and the text also gets a lighter gray. The problem is, that one can not copy the text from it, in a disabled state.

So how can I make a QLineEdit properly non-editable and also make it look like it. In Windows such a control is usually gray, but the text stays black. Of course I could set the style manually, but this means that it is hard-coded and may look wrong on other platforms.

Answer 1

After making the line edit readonly, you can set the background and text colors to whatever you like :

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

Since Nejat pointed me into the right direction with his answer, here is the code, that I now use:

QPalette mEditable = mGUI->mPathText->palette();  // Default colors QPalette  mNonEditable = mGUI->mPathText->palette(); QColor col = mNonEditable.color(QPalette::Button); mNonEditable.setColor(QPalette::Base, col); mNonEditable.setColor(QPalette::Text, Qt::black);  ....  void MyWidget::setEditable(bool bEditable) {     mGUI->mPathText->setReadOnly(!bEditable);     if(bEditable)         mGUI->mPathText->setPalette(mEditable);     else         mGUI->mPathText->setPalette(mNonEditable); }
