If SWT.MeasureItem listener is used to set Table row height there is workaround to avoid the freeze. Remove the SWT.MeasureItem listener after handleEvent(...) is called for a first time (and height is set) from the table (instance must be final).
final Table table = new Table (shell, SWT.MULTI | SWT.BORDER | SWT.FULL_SELECTION);
.
.
.
table.addListener(SWT.MeasureItem, new Listener() {
@Override
public void handleEvent(Event event) {
event.height = 40;
table.removeListener(SWT.MeasureItem, this);
}
});
I'm unable to reproduce the freeze with 4.4.2 and 4.6 master. Can you try with the latest I-build and see if you can still reproduce the problem -- http://download.eclipse.org/eclipse/downloads/drops4/I20151203-1230/download.php?dropFile=eclipse-SDK-I20151203-1230-macosx-cocoa-x86_64.tar.gz Can't be reproduced with SWT from the I-build only with SWT from 4.4.2. org.eclipse.swt.cocoa.macosx.x86_64_3.103.2.v20150203-1351.jar: freeze org.eclipse.swt.cocoa.macosx.x86_64_3.105.0.v20151202-1903.jar: no freeze I can't reproduce the bug on some older Mac OS X versions.

Does the problem happen with Eclipse 4.5.1 or 4.5.2 M-builds? If yes, we can try to identify the commit that fixed the problem and backport it for 4.5.2. Eclipse 4.5.1 downloads - http://download.eclipse.org/eclipse/downloads/drops4/R-4.5.1-201509040015/ Eclipse 4.5.2 M-builds - http://download.eclipse.org/eclipse/downloads/drops4/M20151209-1000/ (In reply to Lakshmi Shanmugam from comment #4) > Eclipse 4.4 stream is not under development anymore.

I can reproduce this with Mac Os X 10.11.2 org.eclipse.swt.cocoa.macosx.x86_64_3.104.1.v20150825-0743.jar which I believe is Eclipse 4.5.1 BTW, is there a way to prevent the double-click to resize the column? I am using SWT.MeasureItem listener to calculate the width, so removing it upon first measurement is not an option. Can you please try with the 4.5.2 candidate build? I suspect that the freeze may be due to Bug 434393, which has been fixed in the 4.5.2 stream. (http://download.eclipse.org/eclipse/downloads/drops4/M20160120-1000/) From comment#3, this bug doesn't happen in 4.6 stream. Also, looks like the problem mentioned was caused by Bug 434393 which is fixed in 4.5.2. *** This bug has been marked as a duplicate of bug 434393 *** |
Created attachment 258392 [details] Snippet to reproduce bug Reproducible on Mac Os X El Capitan 10.11.1. Add Table listener to SWT.MeasureItem. Double-click on separator in table header to resize column to minimal size. OS.objc_msgSendSuper(objc_super, long, long) method in main thread doesn't finish.
