In the project, I am trying to take an image from the user using a file directory, resize it with the value selected from the combobox, and show the resized version in the application, but only the size of the image is printed. How can I solve this problem? Since I’m new to this language and program, I don’t know the basics very well, please help.

I’m Trying To make a Timer App in Qt With C++ , One Of its features is its Minimized Version I.e. by clicking a Button you can minimize the main timer app and a small version of it appears in corner of your screen that displays the time with only 2 buttons to start/stop and maximize the timer.
BUT the problem is I don’t know how to synchronize the two timers(labels)
