How to resize a GUI (which contains many items)

Asked by Diana Acreala on 3 Jan 2012

Hello
I'm coming with a question about resizing a GUI in Matlab. I found the following examples on the site: "Panel" and "An Address Book Reader (GUIDE)" but it's not behaving as it should. For example the text on the buttons does not scale (I can't see the entire text when making the GUI small). About the text it is said this:"You can enable text in controls to resize automatically by setting the component's fontUnits to normalized, without the need for a ResizeFcn." and this is not working also. What about dealing with components like:edit text, table, axes, listbox, pop-up menu? Is something special about these when we talk about resizing?
I would be very grateful if you could help me. Thank you in advance! Diana A.

Hi Diana Acreala,
This kind of problem is easily solved in python, but in matlab you need to create your own SizeChangedFcn to force the width and height of UI components to be fixed while the size of the parent window become larger or smaller.
I'm appending a rar file composed by two .m files. One script hold the code about the generation of the GUI and the other script is the edited SizeChangedFcn that is called by the GUI.
Hope I have helped you.

d = dialog ( 'windowstyle', 'normal', 'resize', 'on' );
uicontrol ( 'parent', d, 'style', 'pushbutton', 'units', 'normalized', 'position', [0.1 0.1 0.5 0.5], 'string', 'test', 'fontunits', 'normalized', 'fontsize', 0.1 );

Hello! Thank you for the fast response. It's not clear for me so I would ask you where should I place this code?
Thanks!
As I dont know your code... so I cant say.
Is your gui created in GUIDE? or like my example?
Problem with Robert Cumming's Answer.....
But if the fontsize is changed to 0.7 (for example), then the text on the pushbutton becomes pretty big. Then on resizing the whole GUI window, when the button becomes smaller, the text does not. It is displayed as t...
How to set the text such that, when the button becomes smaller, the text becomes proportionally smaller.
Thanks in advance

My gui is created in GUIDE. Now I found another example in Matlab help. I searched in HELP after resize and the third thing (starting with the first top) found called: 'Figure Resize Functions' contains the example that helps me.
This is actually what I want but it's very complicated. There is a lot of math and I really can't get the algorithm.
The gui in this example is very simple..I have a lot of elements on my gui and at this moment it's terrible for me to resolve this problem.
Would be very simple if I would understand the calculation of the coordinates.. what do you think? Is there an algorithm or the math is made after testing?
Thank you!

I dont use guide, and I would advise you learn how to create a GUI wihtout it - it will benefit you in the long run.
The idea however is the same - you need to set all your preoperties to have units which are normalized - then when you resize they will be resize automatically.

Hi everybody,
I have the same problem, using GUIDE. I want to set all the elements Units and FontUnits to 'normalized'. It appears to work correctly for all kind of elements EXCEPT : 1/ for the images inserted in buttons => I handled it by writing a specific code in the Resize function 2/ for the FontUnits of panels or button groups => I don't understand what GUIDE is doing....
In the last case indeed, when I set panels or buton groups FontUnits to 'normalized', GUIDE automatically turns the FontSize attribute to '-1'. It is then impossible to change it. And when running the program, the font is still not affected by resizing...
Any clue to explain this unusual GUIDE's behaviour or to solve it by some lines within the resize function would be truly welcome.
Thanks,
Djekko
