How can I save a GUI window in Matlab(e.g. as png)? -


i created gui inside matlab;

to make easy understandable let's there static , non static textfield , 1 push button

in nonstatic text field 1 can enter number , pressing push button answer in static text field, let's 2*a answer;

now want have screenshot of gui there can see number in non static field , result in static text field; how shown after pressing button...

how can achieve that?

thanks in advance.. :)

ok it's more simple thought , thescreencapture option might overkill in situation.

what need getframe function, captures content of axes or figure of choice, here gui.

here code simple example can copy , paste. upon pressing button, new window appears content of gui. can replace part of code call imwrite save image in png format. useful code is:

%// capture content of current figure f = getframe(gcf);

the image data stored in cdata property of structure f, can save eg with. 

%// imwrite(f.cdata,...)

so whole code following:

function testgui clc  hfigure  = figure('position',[300 300 300 100],'units','normalized','name','myfigure');  handles.edit1= uicontrol('style','edit','string','','position',[40 50 50 30]); handles.edit2= uicontrol('style','edit','string','','position',[100 50 50 30]); handles.snapshot= uicontrol('style','push','string','snapshot','position',[160 50 70 30],'callback',@(s,e) snapshot_callback);  guidata(hfigure,handles);  %// callback button 1     function snapshot_callback         handles = guidata(hfigure);          %// double entry edit box 1. (do whatever want)                  x = str2double(get(handles.edit1,'string'));          newx = 2*x;         set(handles.edit2,'string',newx);          %// take screenshot!         f = getframe(gcf);          figure()         imshow(f.cdata); %// image data in f.cdata. can replace imwrite(f.cdata,...)          %// update handles structure.         guidata(hfigure,handles);     end end

and screenshot computer: on left initial gui , on right new figure generated content of gui.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
