    Hi
    I am trying to set a background image on a QTextEdit using setStyleSheet -

    @textEdit->setStyleSheet(QString::fromUtf8("background-image: url(:/images/Chrysanthemum.png);background-attachment: fixed"));@

    However, this doe not work.

    Am i misunderstanding the documentation or is it not possible?

    Thanks

      You need to add this line:
      textEdit->setFrame(false);

          Just out of curiousity have you tried this:
          @
          textEdit->setStyleSheet("background-color: red);
          @

          and if that works fine try (of course your image file needs to be in the same dir as your sources then)
          @
          textEdit->setStyleSheet("background-image: url(Chrysanthemum.png); background-attachment: fixed");
          @

          if that works too I'd guess something is wrong with your way of setting the file location.

            Hi
            @textEdit->setStyleSheet("background-color: red);@
            works fine
            @edit->setStyleSheet("background-image: url(bg.png); background-attachment: fixed;");@
            Does not!
            What can be wrong

              It is working perfectly well on my computer:
              @ui->textEdit->setStyleSheet("background-image: url(:/nedge.png)");@

              Perhaps, you have not added your image to the resource file. Add "bg.png" to resource file and it should work.

                Thats very strange indeed, because an example from the "Qt Style Sheets Examples":http://qt-project.org/doc/qt-4.8/stylesheet-examples.html#customizing-specific-widgets is pretty much the same
                @
                QTextEdit, QListView {
                background-color: white;
                background-image: url(draft.png);
                background-attachment: fixed;
                }
                @

                My only guess is that somehow the file location is not correct. The bg.png file is located inside your source folder?

                  OK
                  Here is my complete code, the image bg.png exists in the directory where the app is being run but is not set as the background
                  @#include <QtGui>

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

                   QTextEdit* edit = new QTextEdit();
                   edit->setWindowTitle("QTextEdit Background Image");
                   
                   edit->setStyleSheet("background-image: url(bg.png)");
                  
                   edit->show();
                   return app.exec();
                  

                  }@

                    There is a mistake in the syntax:
                    @edit->setStyleSheet("background-image: url(bg.png)");@

                    It should be:
                    @edit->setStyleSheet("background-image: url(:/bg.png)");@
                    and "bg.png "must be" added to resource file and should in source directory

                      Hi
                      I still cannot get this working!
                      This is my .pro file
                      @TEMPLATE = app
                      TARGET =
                      DEPENDPATH += .
                      INCLUDEPATH += .

                      Input

                      SOURCES += main.cpp

                      RESOURCES +=
                      res.qrc
                      @
                      I used QCreator to add this image to the resource file
                      but still no joy

                      frustrated

                        I suppose there is only one way I can help you now. Make a zip file of your project and upload the download link so that i can download the project and look for the problem.

                                You had committed a silly mistake in adding the image to resource file. The prefix should had been "/" but it was "/images" in your case (it is also correct but) your folder containing the image was also named as "image", so the address of image should have been "/images/images/bn.jpg". It is working fine now. I have changed the prefix to "/" from "/images". So now the valid address is "/images/bn.jpg"

                                  Thanks, but it still does not work for me
                                  There must be something different in our systems, but I dont know what!
                                  do you have any ideas?

                                    As you said it is not working under windows but working under linux perhaps It’s the windows style that prevents it then.

                                      I take it that you are using Linux then?
