[Graphics] Two questions ... [message #447850]

Hi !

With Swing, I used this little piece of code to make a screen capture :

try
{
r = new Robot();
}
catch (AWTException awe)
{
System.out.println("robot exception occurred");
}

Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
Image img = r.createScreenCapture(new Rectangle(0, 0, d.width, d.height));

Then, I could play with it using :

Graphics tig = img.getGraphics();

My two questions are :
1) how can I do the same thing using SWT ?
2) is it possible to capture a SWT Shell or any other component of the Shell
using java or have I got to use a "native" way ? (if "native" needed, any
hints on both Windows and Linux platforms ? I only know very few about C
and C++ and nothing about linux libraries).

TIA

You can create a GC on the Display, and then use GC.copyArea.
