Hi,

I have a gui with a textbox that is showing the frames of a movie while is playing. When i press pause, everything pauses. Is there any way to copy or print the 'Current frame' showed in the text box while the movie is in pause??

If you have a handle to the textbox, you can access its text through its "String" property. You can get a handle to it with the "findobj" or "findall" functions. For example, if there is only one textbox in the image, you could do the following.

textbox = findall(gcf, 'Type', 'textboxshape');
disp(textbox.String);

Hi Mr.Whitfield,

thanks for your answer.

But is not working. Maybe I did not explain well.

I have a gui with a text, which is changing when the video is playing because is showing the frame numbers. I want to display the current frame number when I pause the video on the gui.

I tried your answer but did not work or maybe I put it in the wrong place.

Here is a screenshot of the gui and a part of my code.

if true
  % code
end
function pushbutton3_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton3 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
videoObject = handles.videoObject;
set(handles.pushbutton4,'Enable','on');
set(handles.pushbutton3,'Enable','off');
axes(handles.axes3);
for frameCount = 2:videoObject.NumberOfFrames
    % Display frames
    set(handles.text3,'String',num2str(frameCount));
    frame = read(videoObject,frameCount);
    imshow(frame);
    drawnow;
end
set(handles.pushbutton5,'Enable','on');
set(handles.pushbutton4,'Enable','off');
%----PAUSE/PLAY---
% --- Executes on button press in pushbutton4.
function pushbutton4_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton4 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
 if(strcmp(get(handles.pushbutton4,'String'),'Pause'))
      set(handles.pushbutton4,'String','Play')
      uiwait();
  else
      set(handles.pushbutton4,'String','Pause');
      uiresume();
end
