打开窗口选择图像C ++

Question

I am using c++ in ubuntu 12.04 using gcc. Am trying to perform few image processing tasks using opencv. For this, I want the user to select an image. Is it possible to open the directory explorer through c++, and let user choose the image, by selecting folders or drives, etc.? I actually did not know how to google this question exactly, my apologies if this is pretty rudimentary. Your help is much appreciated. Thanks in advance

Answer 1

You will want to use a GUI toolkit like Qt . They ususally have some sort of function for what you want. In the case of Qt the QFileDialog would be good.

For learning Qt: There are official tutorials or maybe this question .

If you want to go down this route you can also use a completely separate program just for getting a file name. Something like zenity maybe. Which platform do you want to do this on?
