Parameters in GUI functions

Hi, I have this function to be used with GUI. But how do I pass over "parameter" to be used in another function (e.g RunButton_Callback)? If it is a text like in this example I found a workaround by set it to a textbox and then (in the other function) get it from that textbox. But what to do if it is a vector parameter?

function InputButton_Callback(hObject, eventdata, handle)
[Qfile]=uigetfile('*.txt','Select a file');
[parameter]=QImport(Qfile);

nilsotto - just save the parameter to the handles structure using guidata as

 function InputButton_Callback(hObject, eventdata, handle)
 [Qfile]=uigetfile('*.txt','Select a file');
 [parameter]=QImport(Qfile);

 % save as a field within parameter
 handles.parameter = parameter;

 % update the structure
 guidata(hObject, handles);

Now, in any other callback you can check to see if this field exists and then use it.

 function someOther_Callback(hObject, eventdata, handle)

 if isfield(handles, 'parameter')
     % do something with handles.parameter
 end

Many thanks Geoff, now it works fine :-)
