Re: [eclipse-dev] No more handles in SWT, can this number be configured?
|
What everybody.
Unfortunately, it looks like deviceData.objects also "only" tracks the
disposable objects, not all objects. For example, if I create 1000
Labels and enable tracking these are not included in the count.
----------
DeviceData deviceData = widget.getDisplay().getDeviceData();
int length = deviceData.objects.length;
System.out.println(length);
------------
Best regards, Lars

In any case, the set of objects here don’t necessarily tell you how many handles are being used by the OS, although to a first-order approximation you could guess on a 1-1 mapping.
