Re: [platform-swt-dev] Advanced Graphics

I'm using Windows XP SP2, with an IBM's
 javaw.exe -Xj9.

You can see what I means by all drawing
failed after first rotated drawText("Altitude (m)") .

Here is a snapshot of shell after a
simple paint event:

resize:

any incompatibility with ATI Mobility
FireGL V5200 graphic card ?

Thanks,

There is nothing special you have to do to enable advanced graphics.  What
operating system are you running?  Are you running javaw.exe?  On
Windows, some people have reported that this makes a difference (although
I have never seen it myself). 

Since you have many problems and they all sound related, enter a bug report
with just one of them (say GC.drawXXX() not rendered).  Please include
a small stand alone snippet that shows the problem. Thanks!

Subject	[platform-swt-dev] Advanced Graphics

Hi, 
I'm writing a SWT standalone application that need Advanced Graphics (for
text rotation and alpha...). 
I'm facing the following behaviour: 
- when Canvas is repainted,  graphics works until a rotation is required,
after any following GC.drawXXX() call are not rendered at screen.
- when I resize the shell contaning the canvas manually, all the drawing
are rendered correctly (including rotated texts). 
- for both cases event.gc.getAdvanced() return false (even is rotated text
are rendered). 
- If at start of paintControl() method I set event.gc.setAdvanced(true),
all the painting are very slow. 
- same kind of program inside an eclipse workbench does not have the rendering
problem. 

I'm using an IBM jre with/without -Xj9 option on a recent T60p (having
DirectX9.0c)... 

Is there any option I should use at program or jre launch ? any code I
have to write to set my application to advanced graphics
when it starts ? 

Any help is welcome ! 

Thanks, 
Arnaud. 

PS: my application Display is create using simple "new Display()",
but I also tried Display.getDefault() and Display.getCurrent() which
failed drawing advanced graphics too._______________________________________________
