I am using matlab R2012a (7.14.0.737) 64-bit on a windows 7 PC. I have 2 monitors. I want to be able to open a matlab GUI figure up on the 2nd monitor (on the left).

at the command line opening figures there works fine.

h = figure( ... , 'position',[some -value on the other screen y w h)

but the GUI figure is always made on the 1st monitor despite 1) the correct position values entered into the GUI window properties and/or 2) using the code

set( hObject, 'position',[some -value on the other screen y w h)

in the GUI opening function.

However, if I place this code in the output function it's ok. inelegant as you see the figure appear and then move over. the values in the GUI are set the way i want them to be too. just ignored by matlab it seems. Any ideas?

  • update *

I have since read that matlab calls movegui(fig, 'onscreen') when opening a guide-created figure. arg. I suppose now the issue is how to override that, or how to set 'onscreen' to be the other monitor. Still no solution on this end

You'll notice that GUIDE GUIs in matlab have several default functions that automatically get called upon opening. It's an annoying feature of matlab that at least two of these functions override your default figure positioning. Perhaps one of the solutions discussed here here can be modified to solve your problem.

This cannot be done directly from within GUIDE.

Workaround

Export your figure: GuideMenu -> File -> Export

Replace the line: 

movegui(gui_hFigure,'onscreen');

with: 

set(gcbf, 'position',[some -value on the other screen y w h)

For me (R2012a), this shows up around line 330 of the exported GUI:

...
  % openfig (called by local_openfig below) does this for guis without
  % the LayoutFcn. Be sure to do it here so guis show up on screen.
  movegui(gui_hFigure,'onscreen');   %% COMMENT OUT OR REPLACE THIS LINE
else
  gui_hFigure = local_openfig(gui_State.gui_Name, 
...
