Hello! I have some problems with a slider that I am using for moving my objects on an interface.
This is what I am using:
pos1=get(handles.btn1,'Position');
pos2=get(handles.btn2,'Position');
pos3=get(handles.edittxt,'Position');
slider_value=get(hObject,'Value');
set(handles.btn1,'Position',[pos1(1) pos1(2)-slider_value+1 pos1(3) pos1(4)]);
set(handles.btn2,'Position',[pos2(1) pos2(2)-slider_value+1 pos2(3) pos2(4)]);
set(handles.edittxt,'Position',[pos3(1) pos3(2)-slider_value+1 pos3(3) pos3(4)]);
At this point I am blocked because I really don't know how to move the scroll bar up and down. I don't know how to make conditions... Please help!!!

Please format your code. See: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup
I do not understand the question. The scrollbar is moved by the mouse. And conditions are implemented by the IF statement. Please explain, what you want to achieve.

You would put code such as that in the callback for a slider.
I do not recommend that code. As noted in response to your earlier question, you should instead insert your elements in a uipanel and then set() the Position of the panel in your scroll callback: that will have the effect of moving everything contained within the uipanel all as a group.
If you want to position a slider to a particular location, you set() the value property of the slider.

That corresponds to using "normalized" units in my prior discussion of your options, http://www.mathworks.com/matlabcentral/answers/15641-adopt-the-gui-window-to-my-computer-settings
As I noted then: some GUI elements (especially text) look very ugly if they are specified in "normalized" units
