Stop opening a figure window while using uiwait to pause a playing video in app designer

3 views (last 30 days)
In my developed GUI, videos corresponding to alphabets are playing. I wanted to pause and resume those videos using push button. So, I used two different push button for pausing and resuming the playing video and used uiwait and uiresume functions, respectively. Now, when I click the push button of pause while playing the video, a blank figure window opens.
Can anyone suggest me a way to stop opening the figure window?

Please share the code; at least share the callback of the pause button.

% Button pushed function: PlayButton
function PlayButtonPushed(app, event)
alph = app.InputDataEditField.Value;
Folder = 'F:\test_vids';
for k=1:length(alph)
aFile = fullfile(Folder, alph(k) + ".avi");
videoFReader = VideoReader(aFile);
n=videoFReader.NumberOfFrames;
for m=1:n
frames=read(videoFReader,m);
imshow(frames, 'Parent', app.UIAxes);
end
end
end
function PauseButtonValueChanged(app, event)
uiwait
end
function ResumeButtonPushed(app, event)
uiresume
end
Anything else do you require? First code is to play the video. 2nd one is for pause and resume push buttons

Use

uiwait(app.UIFigure)

and

uiresume(app.UIFigure)

(or whatever the handle to your app's uifigure is, if you changed it from the default app.UIFigure)
