Eddy

[quote author="theblizzfreak" date="1310929596"]okay so how does one put a layout into a application and how does one structure it ;)[/quote]

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.

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

[quote author="theblizzfreak" date="1310934733"]yes :) it all looks the same in terms of how i structure the gui ?[/quote]

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.

theblizzfreak

when i look at your example and my example they look exactly the same the only difference is yours actually moves the buttons and i dont know how to do that? please can you tell me how you did it exactly and also tell me how you figured that out please thanks! :)

Eddy

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.

theblizzfreak

ill read the book :)

Eddy

Ok, enjoy it!

If you have more questions feel free to ask here. I suggest to start a new topic with as much detail about what you want as possible. Show your code or what you have accomplished yet.

This will be easier for others to help you.

theblizzfreak

what does it mean by application-wide resources. in the book? my guess was like the applications overall coding bytes management? on page 21

its located 5 lines up from the bottom of the page

Eddy

QApplication is a QObject that is run as your program. It handles a lot of things like user interaction. You can read more on it in the docs. But i suggest to read further on first to get the general understanding of Qt.

theblizzfreak

OK :)
