| Re: [platform-swt-dev] natives with project builder. |
Can some kind soul send me a working project builder project with a java class which defines a native and the matching C code? I'm sorry for being such a dolt, but I'm still wrestling with PB, and I'd rather be hacking Carbon. ;-)
OK, after lots of experimenting with a - Cocoa - Carbon & JDirect - Carbon & JNI based SWT version I'm pretty sure that "Carbon & JNI" is the way to go.At first SWT in Cocoa seemed to be simple because everything is Java, however there were quite a few issues for which I had no good solution. The most important ones: performance and robustness. I will post the Cocoa version together with some analysis in the next couple of days.
After working on the Cocoa version (and getting major parts of StyledText and Tree to work), I started a JDirect based Carbon version of SWT. JDirect seemed to be easier to use than JNI because Carbon natives can be called without writing any C code. However, when writing an event loop based application I got some strange interaction with an AWT (?) event thread and event delivery was not reliable. In addition getting all the C constant definitions on the Java side is a major pain.
So a week ago I gave up and started a JNI based Carbon version.First I wrote the enclosed (WaitNextEvent based) application and everythings seems to work faster, more reliable, more predictable, and I don't get any interaction with AWT event processing.
Today I got something similar to SWT Composites and Scrollables up and running in Carbon (using UserPartControl and a Control embedding hierarchy). After some cleanup I'll post that on the weekend.
