        ok, I got it.

        It's easy to solve you need to use layouts.
        "Here is a good explanation on how to use them :":http://doc.qt.nokia.com/4.7/layout.html

        i have made a simple ui file you can look into. A picture tells more than 1000 words.... ;)

        If you have any more specific questions, feel free to ask.

          There is also a slider example which may provide you already at least some of the logics you need.

            Hi koahnig,

            theblizzfreak just needs a QScrollarea with widgets in a layout.

            @theblizzfreak
            i suggest to look into the sliders example later on, which is more detailed and offers a lot to learn about signal and slots also.

                    In Qt Designer there are buttons for that.
                    select the widgets you want in a layout and then click on one of the layout buttons.
                    "A Quick Start to Qt Designer":http://developer.qt.nokia.com/doc/qt-4.7/designer-quick-start.html

                    you can use the ui file i provided and replace it with the one you got by using the wizard to make a QMainwindow based program in Qt Creator.

                        Isn't that what you asked for? What else do you want to accomplish?

                          haha np ill explain again basically i want a slider that makes my ScrollArea Window with buttons inside move up and down based on the slider :)

                          like the scroll bar on a webbrowser where you can go up and down the webpage but for buttons in an application :) thanks in advance if you need some visual examples ill get some pictures

                            The ui example i made for you has a scrollbar if the dialog is too small for all the buttons. You can scroll down and up.

                            I have 3 buttons in a scrollarea in a layout.

                            If that's not what you want please give us a picture.

                              how do i give the slider an action to make it move the buttons up or down on the vertical layout ?

                              i tried using the Signal and Slots editor but it dont make any sense to me accept that i can connect things together

                                    Edit : please don't change your post afterwards. It makes things even more complicated to follow. Use the edit button on the right like I did.

                                        You can see the structure of what i did on the right in Qt Designer.
                                        I explained where you could find the buttons to add layouts, i even gave you a link to the docs where the details are explained. I suggest you go back in time and read all the posts in a chronological order. Follow the suggestions made like reading the tutorials, wiki or whatever.
                                        If you still feel lost i strongly advise you to read a good book about Qt to get the overview you need to understand all the details. "Here is a good book :":http://www.qtrac.eu/C++-GUI-Programming-with-Qt-4-1st-ed.zip.
                                        Read the first chapters and you will feel much comfortable using Qt.
