heres a link to download it http://www.2shared.com/file/sEd0hUOH/mainwindow.html

In that case you could make a minimal example ui that shows only the problem you are having.

theblizzfreak

im sorry how would one go about doing that?? my guess is make a knew project and create a slider in the Designer and scroll area with a button and then give you the UI file?? :)

Eddy

hold back not too fast ;-) , i will first look into the file you sent at the same time i asked for the minimal example.

theblizzfreak

ah HA :D typical situwations :P

Eddy

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.
"Sliders Example ":http://doc.qt.nokia.com/4.7/widgets-sliders.html

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.

theblizzfreak

okay so how does one put a layout into a application and how does one structure it ;)

theblizzfreak

Oh okay thanks there Eddy :) helped me alot brb ill see if i can get it too work

theblizzfreak

okay im totally stumped i dont even know where to start do i make a class? or use the QT Designer? where do i put the class,etc

Eddy

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.

theblizzfreak

okay i have my layout and my button in my layout i have my slider :) and i also have a scroll area under my layout : ) now what do i do? :D

Eddy

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

theblizzfreak

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

Eddy

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.

theblizzfreak

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

Eddy

Have you tried my example?

theblizzfreak

yes :) iv looked at it but it all looks the same in terms of how i structure the gui ? what am i missing? this QT is very strange to work with

Eddy

i don't understand this. Can you explain more?

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.
