I have tested adding it to a setTimeout to see if that helps and nothing. Reproducible: Always Steps to Reproduce: 1. Install Foxgame (probably it can be found a minimal case but this is what I have) from http://www.foxgame.org/foxgame.xpi 2. Open Tools -> Add-ons -> Foxgame Options. 3. Select 4 tab "Messages" 4. In the bottom click on Add, and in the new dialog check "From" Actual Results: The from textarea is shown but the window is not resized even after a window.sizeToContent() call. Expected Results: It should have resized the dialog. If after that you select "Spy Report" it resizes without problem, but not only that, if you select back "PM" now checking/unchecking resizes as it should. I have tried it on a FF3 RC2 protable clean installation, my reports are that this happens in RC1 and RC2 but I have not tested it on other version / OS.
This was caused by Bug 300030.
I've seen the same issue while working on the Firefox extension FoxClocks. Previous release versions of Firefox (<= 2.x) are unaffected. To reproduce: call window.sizeToContent() where no resizing is necessary - subsequent calls to window.sizeToContent() then fail. Thus the behaviour can seem intermittent. (Corollary: workaround is to call window.sizeToContent() only when resizing will occur, e.g. on hiding/unhiding an element.)
Some of our users confirm this as well: http://bugs.code.downthemall.net/trac/ticket/731 Was supposed to be fixed by: bug 371508
This bug breaks the popup window feature of my extension, Text-to-Image, on Windows XP, Windows Vista, and Linux (Firefox 3.1 builds only). In either case, a zero height/width popup is created that is either invisible, unresizable, or only as large as the window header.
If sizeToContent is called when the size already fit to the content, then all next calls to sizeToContent will not work. If you get ride of this test : http://mxr.mozilla.org/mozilla-central/source/xpfe/appshell/src/nsXULWindow.cpp#1714 sizeToContent has the correct behavior. I don't know why, but I think we are on to something.
Created attachment 349968 [details] minimal test case Open this xul dialog page : Click on hide, then show, then hide, then show, ... it works. But click twice on hide or show, it stops working.
Seems to work know. Resolved ?
Yes, it seems to work for me in current trunk build with the testcases. However, the FoxGame extension gives me problems trying out if it works there. I get js errors in the error console, so I can't really test the extension. Paul, you mean this seems to work now that bug 465448 is fixed?
Still broken: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6
Since 7.0b1 candidate .resizeBy is also broken, and it's always! Nothing in dev toolbar or firebug.
