In a GUI, I have an image and the user selects a rectangle using getrect that is later used to crop the image. As the user is selecting the rectangle, I would like to display the rectangle coordinates in real time so that the user can manually seek to match desired coordinates, if they want. (I need to keep the manual aspect of getrect because sometimes there aren't any desired coordinates). Is a popup msgbox the best way to do this, or something else?
Let's say in the following code, the user wants to choose a rectangle with coordinates [100 200 100 100]. How can they get feedback on the coordinates as they manually draw the rectangle?
rect = getrect
