MATLAB: I want to pop a new window in Matlab GUI.

matlab gui

i want to pop a new window in Matlab GUI. I need to display three figures on new window. My existing GUI is full of figures and push buttons. enter preformatted text here

function pushbutton7_Callback(hObject, eventdata, handles) 
global img; 
[Red, x] = imhist(img(:,:,1)); 
bar(x, Red, 'Red');
[Green, y] = imhist( img(:,:,2)); 
bar(y, Green, 'Green'); 
[Blue, z] = imhist(img(:,:,3)); 
bar( z, Blue, 'Blue');

how can I display output of these commands on new window which contain three figures (one for each color).

mania - just create a new figure and use subplot to create 3 axes which you will update accordingly.

MATLAB: Do the static textboxes in the GUI print in gray color unlike the GUI background

The textboxes in a GUI not printing in the same color as the background is an expected behavior.

A workaround for printing the textboxes in white color is to set the background color of the textboxes to white. The color of the textboxes can then be reverted to the original color after the printing is completed. The following code can be added to the Shortcut to accomplish this task.

% Show Hidden Handles to identify the GUI figure
set(0,'showHiddenHandles','on')
% Identify the GUI figure
figureHandle = findobj(0,'Type','Figure');
% Extract the GUI's children
childrenHandles = get(figureHandle,'Children');
% Identify the textbox object handles
textBoxHandles = findobj(childrenHandles,'Style','text');
% Store the original background color of the textbox
originalBGColor = get(textBoxHandles(1),'BackgroundColor');
% Set the background color of textboxes to white 
set(textBoxHandles,'BackgroundColor','w')
% Print the GUI figure
print(figureHandle)
% Revert the background color of textboxes to the original color
set(textBoxHandles,'BackgroundColor',originalBGColor)

Note if using PRINTDLG (or other substitutions for PRINT) that you may need to allow printing to finish before the last line

set(textBoxHandles,'BackgroundColor',originalBGColor)

can be executed. Simply insert a PAUSE command or manually remove this last line and execute it separately.
