    Hi and welcome
    The QLabel will be fit to the image size and not the other way around. (sadly)
    If you want to keep the image with in a some box, you must re-size it your self.

    QPixmap p( QString(":/dog.png") );
    int w = label->width();
    int h = label->height();
    // set a scaled pixmap to a w x h box keeping its aspect ratio 
    label->setPixmap(p.scaled(w,h,Qt::KeepAspectRatio));
    

    Note that you should the the MaximumHeight of the QLabel (with the dog) to the max size you think it should have before
    setting the image. (label->setMaximumHeigh( xxx) )

    Hi @mrjj,

    Thank you fer helping me. Your solution works, even though as the dog's Image needs to be bigger as there will be some details that needs to be showed clearly.

    I tried to increase the available space (reducing the spacing between the horizontal spacers) but the result is still being the same (like if the change does not were done).

    Any Idea?

    Thank you for your help and time.

    Best regards.

      Hi

      Well im not 100% sure how you setup the inner box.
      if you want frameAnimalConatiner to be bigger, you could set its MinimumWidth or height and
      spacers will follow that.

      Are you planning on animation later on ?

        Perfect! You are right, I don't know why it wasn't working but it works now.

        Thank you so much.

        P.D: No, the images are going to be static.

        Cheers.

          Super!
          well layouts are funky. And smart.

          Ok. Since you just did not take an image program and made
          one new picture with all in it, I assume you
          going to use different images overlaid ?

            When a picture file that I bring in from Windows is imported into qt, it breaks. What should I do?

                  Hmm. that is odd.
                  Do you load the same image file on both platforms?
                  What is the format ? (jpg,png) etc.

                  Can you upload the original image so i can try in my linux box?
                  Maybe a support SO has issues on your box or something like that.

                      Hi
                      I tried in Qt 5.7 on Mint/ubuntu linux and it was shown as
                      expected. ( not broken)

                      I put the image in res file and showed it on a label.

                      Do yo use QImage or how do you show it ?

                        @mrjj oops, I had a mistake. Widget form has a dot. so it seems to have appeared.
                        if it occurs again, I will ask something someday. :)
                        thank your helping :)
                        Have a nice day!
