Irrlicht Engine

Hey there. I have some questions about the GUI and the mouse.
1- How do I put the standart toolbar? (the one that has file, edition, help, and so on)
2- I want to do this: when the user click with the mouse on a on-screen image (2D), I want that around the mouse appears a small rectangle with a small portion of that image (say, around 30 x 30). How can I do that?
3- How do I do to allow the user to open an image from a file to load ii in the screen? (much like opening an image with Paint)
4- Can I crate and save bitmaps using Irrlicht?

Thanks

1 & 3:
You can start by examining tutorials 5 an 9:
http://irrlicht.sourceforge.net/tut009.html

2: look at driver->draw2DTexture (or similar name, i forget if that's right). When you catch the button clicked event you can take the texture of the clicked button and then draw it at the mouse's coordinates each frame.

And 4: Of course, use the IImageLoader and IImageWriter provided in the scene manager.

Any help with those two functions? An example or something like that. Thanks

Check the VideoDriver API, these are pretty simple to use.
