GUI screen resolution auto-resize

107 views (last 30 days)
Is there a way to have a GUI in guide auto-adjust to fit current screen resolution, and/or can I hard-set the resolution of the interface at a specific value?

You can set the figure Units property to be Normalized, and set the Position property to be [0 0 1 1] if you want full screen. Or, if more appropriate, you can set the Units to Pixels or to 'cm' and use the appropriate values for Position.

You can mix and match units. Some can be normalized and others in pixels, though that may lead to overlap. It's best to have all normalized and then tweak the size of the control to leave the lower left corner in the same place but you just adjust the width and height on a customized control-by-control basis if you want.

True full screen requires operating-system specific calls. Using position [0 0 1 1] covers all of the area except title bars and docks and trays -- all of the area that the window manager normally gives programs. To go beyond that you need one of the utilities like Image Analyst posted or such as https://www.mathworks.com/matlabcentral/fileexchange/11112-fullscreen
I have to agree with Adam that just scaling everything usually ends up looking bad. It is also problematic when you get to screens with different aspect ratios.
What I ended up doing was writing a series of utilities to do programmatic layout.
(Unfortunately, I cannot release them as-is, for copyright reasons, and I never got around to re-writing them.)

Thanks for the answers everyone. Changing the unit type seems to do the trick well enough.

You have to set all the 'units' properties of all the controls to 'normalized'. To do this, type control-a to select everything in the GUI, then set the units property to 'normalized'. This may/will not set the units of controls inside a groupbox panel so you may have to set those separately.
Then, in the OpeningFcn() of your GUI, call the attached MaximizeFigureWindow (if you're using Microsoft Windows) to maximize the window. This truly maximizes it, unlike setting the position property of the GUI. Setting the Position property always seems to leave the window slightly misaligned anyway - bottom left is never at 0,0 like it should be.
