MATLAB: GUI figure doesn’t move

gui

Hi all,

I tried to move my GUI so part of it is in monitor 1 and the other part in monitor 2. I tried either use movegui or using groot to get all monitor position and set the figure handle to the set position but the GUI . My first monitor has [3200×1800] pixels and the second monitor is [1024×768]. Any suggestion please?

r = groot;
pos = r.MonitorPositions;
posShift = [pos(2,1)-500,pos(2,2)];
set(handles.figure1,'position',pos(1,1:2)+posShift ,pos(1.3:4)]);

There is a limitation with setting the size of a Matlab figure e.g. when the limits exceed the monitor size:

siz  = get(groot, 'ScreenSize');  % e.g. [1 1 1920 1200]
FigH = figure('OuterPosition', siz);
drawnow;
get(FigH, 'OuterPosition');

Under Windows you can use https://www.mathworks.com/matlabcentral/fileexchange/31437-windowapi to set the window where ever you want, even in fullscreen (on top on the taskbar) or beyound several screens.

MATLAB: How to move the position of the GUI on the screen from the default

the issue was resolved by restarting MATLAB!! There might have been a bug, but my guess is that had something to do with switching back and fort btw external and default monitor of my machine. I reset the position data in the position property of the main Figure of the gui and it worked after trying the same thing over and over!!

thanks for all your suggestions

MATLAB: Linking multiple GUI’s when moving the Main GUI

Ciuban - you can try adding a listener (see learn to use events and listeners) to capture the movement of the main GUI so that when its position changes, the other three GUIs position changes as well. For example, suppose that we have two GUIs, the main one and a smaller one that is situated to the right of the main one. The main GUI (named/tagged as Gui1) launches the second GUI (named/tagged Gui2). Within the OpeningFcn of the first we do

 function Gui1_OpeningFcn(hObject, eventdata, handles, varargin)
 % Choose default command line output for Gui1
 handles.output = hObject;
 % place Gui1 in centre of screen
 movegui(hObject,'center');
 % launch Gui2 and move to right of Gui1
 handles.hGui2 = Gui2('Visible','off');
 gui1Pos = get(hObject,'Position');
 gui2Pos = get(handles.hGui2,'Position');
 gui2Pos = [gui1Pos(1)+gui1Pos(3)+5 gui1Pos(2) gui2Pos(3) gui2Pos(4)];
 set(handles.hGui2,'Position',gui2Pos,'Visible','on');
 % save the current GUI positions
 handles.gui1Pos = gui1Pos;
 handles.gui2Pos = gui2Pos;
 % add a listener to respond to position changes of Gui1
 handles.gui1PosListener = ...
    addlistener(hObject, 'Position', 'PostSet', @(src,event)onGui1PosChange(src,event,hObject));
 % Update handles structure
 guidata(hObject, handles);

In the above, we centre the main GUI and then move the other GUI to the right of the first one. The listener is created to respond to changes in position of the main GUI. We define the callback for this listener as

 function onGui1PosChange(~,~,hGui)
 % get the handles for Gui1
 handles = guidata(hGui);
 % determine the change in position for Gui1
 newGui1Pos        = get(hGui,'Position');
 gui1PosDelta      = handles.gui1Pos - newGui1Pos;
 gui1PosDelta(3:4) = 0; % don't want any change to width and height
 % determine the new position for Gui2
 newGui2Pos = handles.gui2Pos - gui1PosDelta;
 set(handles.hGui2,'Position',newGui2Pos);
 % save the new positions
 handles.gui1Pos = newGui1Pos;
 handles.gui2Pos = newGui2Pos;
 guidata(hGui,handles);

Here, we determine the change in position of the first GUI (with respect to its x and y position) and then apply that change to the second GUI.

The attached code uses the above to keep the two GUIs positioned together. From the Command Line, just type

 Gui1

to test this out. Note that the second GUI only moves after the first GUIs position has been finalized (i.e. after you release the mouse button). Try it out and see what happens!
