Datatip, GUI screen and open Excel questions

Hello!

Can please someone help me with a simple qustions.

1) I have a plot in my GUI and I enabled Data Cursor. Because I have dates on my X, I converted it successfully. But now, I want to add a character(g) to the Y.

Y is a number(mass in grams), so I just want the datatip showing grams next to the mass value.

pos = get(event_obj,'Position');
output_txt = {['Datum:  ',datestr(pos(1), 'dd.mmm.yyyy')],...
    ['Masa:  ',num2str(pos(2))]};

2) When I run my GUI, I want it to be in the center of the screen. I used movegui(center), but it did nothing. Where should I even place the command in my GUI code?

3) I want my GUI to open an .xls file in Excel and not in Editor.

Hi,

for 2): what error do you get? You should add something like

movegui(handles.figure1, 'center')

for 3): do something like

[f,p] = uigetfile('*.xls');
winopen(fullfile(p,f))

Thanks man!

It worked!

2) But why is there a command movegui(center) and does not specify anything about handles?

3)When I click on PushButton, it opens the explorer asking me to choose a file. Can I get pass that, so it just directly opens up?

[Titus Edelhofer]

2) That's just like many other functions: if no handle is given, it takes the current figure (e.g. hold). More robust usually is to pass the handle.

3) Of course, if you know the file just write

winopen('C:\MyDatafile.xls')

Hi,

for 1): do you mean this:

output_txt = {['Datum:  ',datestr(pos(1), 'dd.mmm.yyyy')],...
  ['Masa:  ',num2str(pos(2)) 'g']};

2) A call to movegui should come into your guiname_OpeningFcn.

3) Don't undertstand the question...

1) Worked like a charm!

2) I've put it in here, but it just pops ERROR.

% --- Executes just before goliGUI is made visible.
function goliGUI_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.

% Choose default command line output for goliGUI
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

if strcmp(get(hObject,'Visible'),'off')
    plot(rand);
end

3) I want to open .xls file in Excel, outside MatLab on PushButton in my GUI. So when I click it, Excel 2007 opens and the file.

Thanks for a quick response!
