Qt QPlainTextEdit background

Question

I want to change the background color of a QPlainTextEdit, how do I do this?

Answer 1

Modify the palette of your plain text edit. Sample program:

#include 
#include 

int main(int argc, char* argv[])
{
  QApplication app(argc, argv);

  QPlainTextEdit edit;
  QPalette p = edit.palette();

  p.setColor(QPalette::Active, QPalette::Base, Qt::red);
  p.setColor(QPalette::Inactive, QPalette::Base, Qt::red);

  edit.setPalette(p);

  edit.show();
  return app.exec();
}

Substitute whatever color you want, of course.
