How to Limit figure size?

The minimum size should be constant but I have been unable to achieve this. I read some stuff but nothing seems to work properlly. Any help would be apreciated.

If you're using a recent version of Matlab, you can accomplish this via the SizeChangedFcn of the figure:

h = figure;
figszfun = @(~,~) set(h, 'position', max([0 0 200 200], h.Position));
h.SizeChangedFcn = figszfun;

In this example, the figure will be always be at least 200 x 200 pixels.

For older versions (pre-2014b), the same thing can be accomplished via the ResizeFcn.

If this works, why doesn't it cause an infinite recursion? Changing the figure size inside the function called after resizing a figure...

Hi thank you for the help but this dont work properlly. Image is always flickering

[Kelly Kearney]

Hmm, good question, Jan, but recursion doesn't seem to be a problem, at least not on my system. I do get the flicker effect if I manually resize the figure smaller than the limit, since the mouse-set size and resize function are fighting each other, but that stops as soon as I release the mouse click.

Perhaps that's the difference between ResizeFcn and the newer SizeChangedFcn? I really haven't looked into it much.

Try setting the figure position in the form [xll yll width height] where xll and yll are the x and y positions of the lower left corner of the figure and width and height are, well, the width and height of the figure. Units are in pixels.

set(gcf,'pos',[10 10 300 200])

Hi Jan,

Thank you for the help. I am using your function. I changed the line 99

This: jClient = jFrame.fHG1Client;

for this: jClient = jFrame.fHG2Client;

and now is working.

I just dont understand how is possible that matlab dont have a native function that do this simple thing as well as a function to minimize and maximize a figure. This is a recursive problem that has many years but is never solved...
