Folder Selector for CEGUI and win32
Posted: Fri Oct 10, 2008 10:23
Hello, CEGUI community!
I while ago I was looking for an open source folder selector for win32 based on CEGUI, but I didn't found anyone.
So I decided to make my own, and share it with others. This is how it looks:
It's pretty simple so far, but if you just need a folder navigator that allows you to move trough directories and logical units, it can do the job.
I've tried to keep the things as simple as possible for the example purpose in the downloadable file below:
Download the MSVC2k8 project & source<--Contains Source and a pre-compiled example in folder bin
Wikified version<--Wikified documentation.
Folder selector is showed in a CEGUI Window, using the method:
Where root is the window where you want the folder selector to be showed.
Here you've got the Folder Selector header. As you can see, it uses DiskObject, wich is a small class without no more dependencies than "windows.h" and stl.
This is how main loop looks:
I know this is not the piece of code that is going to save the world, but it can (hopefully) save some minutes to other developers.
I want to thank CEGUI team for this magnificent library. A revision from you to my code will be a very good feedback
Any other feedback is also welcomed.
