MATLAB: How to maintain aspect ratio of the GUI

aspect ratioguiresize

Hello,

I have made a GUI and designed it to fit well in the entire screen space of my workstation, but if I run the file on my laptop, it doesn't resize or maintain aspect ratio ergo rendering some parts of the GUI inaccessible. How do I make the changes??? Please help…

Thank you in advance…

See http://www.mathworks.com/help/matlab/ref/figure-properties.html#property_sizechangedfcn

You would be able to use this to enforce proportions. Fetch the current figure height and width and use your target aspect ratio to compute the ideal width. If the actual width is larger than the ideal width then make the window narrower leaving the height alone; if the actual width is smaller than the ideal width then make the window shorter leaving the width alone.

Everything else would be set to be positioned proportional to the figure.

The following code resizes and repositions the figure on the paper so that it is as large as possible with a fixed aspect ratio

h=gcf;
pos = get(h,'Position');
aspect = pos(3)/pos(4)  %width/height

set(h,'PaperOrientation','landscape');
set(h,'PaperPositionMode','manual');  
set(h,'PaperUnits','normalized');
s = get(h,'PaperSize');
paperaspect = s(1)/s(2); %width/height
if(aspect > paperaspect)
      set(h,'PaperPosition', [0 .5-.5/aspect 1 1/aspect]);
elseif(aspect < 1)
      set(h,'PaperPosition', [.5-.5*aspect 0 aspect 1]);
else 
      set(h,'PaperPosition', [0 0 1 1]);
end
print(h, '-dpdf', 'test1.pdf');
set(h,'PaperUnits', 'inches');

MATLAB: Determine size of text objects

Create a uicontrol('Style', 'text') with FontName and FontSize as appropriate. The Position of the control does not matter, and you can create it with visibility turned off. Make sure the Units property is set to pixels.

Now, set the control's String property to the text you want. Then, get() the Extent property of the control. The returned height and width are the height and width that would be required to render just that String by itself. This will be the case even if the Position of the control was too small (or too wide) for the string: Extent will tell you the size you actually need for it.

You can of course re-use the same uicontrol to size different strings, by setting the String property and reading out the Extent afterwards.

Delete the unneeded uicontrol after you have sized everything.
