Proportional GUI

Hi everybody, I am working on a project where there is a GUI with buttons, edit-box, images...

I am working with my notebook, but I also need to use this application on others computers, that surely have different monitor.

I set inside Property Inspector, under Position a dimension in PIXEL of 1024x768. Anyway, if I set GUI as proportional, the size fill the monitor.

That is ok, but I would like to open the .exe and immediately fill the screen, as if I pressed the resize button on the upper left hand side.

How can I set this aspect?

Thanks

One possible solution:

jFrame = get(handle(gcf),'JavaFrame');
jFrame.setMaximized(true);

The official TMW Tech note: How do I make a figure full screen programmatically in MATLAB 7.7 (R2008b)?

+1. As long as Matlab supports the JavaFrame property, this is a nice platform-independent solution. If you rely on this feature, it might be helpful to vote here: http://www.mathworks.com/support/contact_us/dev/javaframe.html . I'm afraid the feature could be removed in Matlab 8, when the new HG-objects are enabled, but this is *pure guessing* based and *not* based on real information. I'd really prefer to see the JavaFrame property documented and supported.

I tried this 2 lines of code, but doesn't work!

@Ocram: "Doesn't work" is not precise enough to find out, where the problem is. The code needs Java, so e.g. it fails when Matlab is started with the -nojvm flag. Or perhaps GCF does not point to the wanted figure?

Note that a full screen GUI looks overwhelming on a 27''-monitor. Therefore I'm using this to limit the size:

FigH = figure('Units', 'normalized', ...
              'Position', [0,0,1,1], ...
              'Visible', 'off');
set(FigH, 'Units', 'pixels');
FigPos = get(FigH, 'Position');
FigExt = min(FigPos(3:4), [1024, 768]);
set(FigH, 'Position', [FigPos(1:2), FigExt]);
set(FigH, 'Units', 'normalized');

I also tried this code:

set(gcf,'units','normalized','outerposition',[0 0 1 1])

This resize the figure, but It doesn't fill the screen as the Maximise button does.

You may also try these P-codes : Is it possible to maximize, minimize or get the state of my figure programmatically in MATLAB?

[Jan]

The P-files contain your JavaFrame approach and some checks of the inputs. The different files concerning the Matlab version differ in the P-coding only.

[Ocram]

Hi, I tried these P-files

If I write: figure, maxfig(gcf,1)

the figure fill the screen completely!!

Instead, writing this code inside the GUI, in the openingFnc maxfig(handle.figure1,1)

the figure doesn't change aspect at all!!

Why???

[Jan]

Perhaps the figure size is set later again? You can use the debugger to find this.

MAXFIG fails if the figure is not visible. Therefore I'd use the [0,0,1,1] position in normalized coordinates.

I get this if I run the GUI:

s =

Normal

[Jan]

This error appears, if you want to maximize a figure with disabled visibility.

Answer 7

[Ocram]

And the Opening Fnc is simply this:

% --- Executes just before GUI_prova is made visible.
function GUI_prova_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to GUI_prova (see VARARGIN)

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

maxfig(handles.figure1,1) % maximizes the figure window for the figure with handle F
s = figstate(handles.figure1) % returns the state of figure { Maximized | Minimized | Normal }

% Update handles structure
guidata(hObject, handles);

% UIWAIT makes GUI_prova wait for user response (see UIRESUME)
% uiwait(handles.figure1);

Answer 8

[Aurelien Queffurust]

As Yair suggests in his comment June 7, 2011 at 1:47 am try to put the maxfig call in the outputfcn intead of opening fcn

[Ocram]

Thanks!! Now it works!!!

[Ocram]

If I put it in the outputfcn is ok!

But I need to maximise the figure before the outputfcn, because I need to use uiwait(handles.figure1) in the openingfcn.

Thanks

Answer 9

[Ocram]

Do you have any idea? I mean using these 2 lines of code:

maxfig(handles.figure1,1) % maximizes the figure window for the figure with handle F
s = figstate(handles.figure1) % returns the state of figure { Maximized | Minimized | Normal }

[Image Analyst]

Any idea about what? What about those two lines???
