How do I make an Open File dialog?

in General Discussion • Other • 10 months ago

I'm working on a desktop application, and I want to allow the user to select an image from their computer and display it in the window. I don't think display code will be any problem, I have already implemented a drag-and-drop interface for moving PImages around a canvas.

Anyways, I installed G4P and I've been looking around in there, but I don't see anything that I know will let me open some kind of a file dialog box. Is this part of the Windows API, or is there a wrapper somewhere I can use? Or, if I were to write the thing myself ( not a problem ) where would I start?

You can use the built in file selector in Processing. But this can give a problem because you can't alter the font, the color, the size, etc. etc. It can be found here: selectInput
Or, you can create your own file dialog inside G4P. I bet there will be an example in the forums if you search for it.

OK, I ended up using a JFileChooser, but it's really buggy and crashes all the time. Maybe there's no way around that - but when it does crash, the whole application goes down. How can I prevent that?

EDIT: Wait, nevermind. I changed to selectInput ( which is WAY better than JFileChooser ).

Issue resolved.
