Fonts and Trees
Pages: Prev | 1 | 2 | Next
Message 1 in thread
Hi folks!
I hope it's not a problem that i collect two questions in one mail.
The first problem is with QFont. QFont has some stream-operator
(operator<<) in cpp which i'm missing in java. Do i just not find it or
isn't it there atm? If it isn't there atm can i expect it in the final
release then or is there any workaround if not?
The second question is probably more complex. It's about model based
trees. Yes, there were already some talks about similar things but no
matter how much i search i cannot find a good example. Compared to other
model based trees i know (SWT/JFace, Swing) Qt's treeview and its whole
mvc-system is totally different in almost every way.
So from what i read in the ml already the qabstractitemmodel doesn't
match java very well and therefor qstandarditemmodel is the recommended
way of doing that job. But besides that i never found some good
_dynamic_ example of a tree and a qstandarditemmodel, especially not
with qtjambi.
Almost all examples with qstandarditemmodel were with static data, using
a default model, feeding it with static data at startup and displaying
that. And all dynamic trees i found used qabstractitemmodel in cpp where
they could use internalPointer() for their payload (which jambi for sure
cannot use since it's a void* and therefor wrapped to long).
What i would really appreciate is a simple filebrowser treeview which
queries its nodes on demand. Nothing more, but also nothing less. A
Swing equivalent is attached.
I hope i do not want too much from you guys, but i'm really out of ideas
atm.
Best regards

Hi,
i'm afraid i had a mistake in my original mail. What i wanted to do with
this operator was creating a new QFont from an InputStream. Therefor it
should be operator>> and not operator<< from cpp's QFont. If you also
answered that with your original mail it seems like i won't get it ;).

These are currently not available, but we'll try to get them in place
for next release. In the mean time you have to encode and decode your
QFont object using the primitives available in QDataStream, like the
fontname, size, bold, italic, etc.

Hi Georg,
Actually its almost identical to the concept used at least in Swing if
you take a look at javax.swing.tree.TreeNode, with one minor detail. In
Qt we refer to the model data via the QModelIndex object, while Swing
refers to the data directly. This makes the code slightly more complex ;-)
Qt's item model also support hierarchical tables, but for this example
we're only interrested in one column (the file name) so that doesn't
really affect the code...

You have to use QModelIndex.internalId() in Jambi too and use this as a
lookup into a map. This is at least the most straightforward and generic
approach right now.

Its attached.
However... If you want to browser the file system, you should be using
com.trolltech.qt.gui.QDirModel, does all this and provides icons and
other things with it.

Yeah, after your example i see some similarities between both models. I
think i only had 2 big problems which didn't let me get qt's model:
index() is used to get children and missing payload. But now things are
a bit clearer.

Can we expect a change on that "issue"? Maybe some way to use payload as
an object? Probably by using a separate field in qmodelindex so
internalid() doesn't need changes? Would be really great to have
something alike since using a map and looking items up all the time can
produce quite some overhead. And the whole code would be much nicer ;).

That example really saved my day. Although i get segfaults when opening
the second level I'm really happy with your example. Just have to kill
the segfault now and everything is really fine :D.

Sure i would, but using a fs-browser to show how a dynamic model works
seems to be the best choice to me.
Thanks again for the nice example, that really helped much :)

yes ;-)
We intend to do something with QModelIndex and treemodels to make it a
bit smoother in Qt Jambi.

Did my example segfault?
I cannot reproduce that on windows at least.
At any rate, if you find out why it segfaults I'd like to see the code
so that we can prevent future segfaults.

Nope, not your example. Your example went smooth, but my further tests
segfaulted ;). No idea where the problem is, since it opens the first
layer after / just fine but when i walk into /bin for example it gets
all children and then segfaults. Have to look deeper into it. I will
come back if it's a jambi problem.

Hi Georg,
Regardless of if the crash is directly Jambi's fault or triggered by
something else, we would apprechiate if you would tell us how it
happens, so that we can prevent virtual machine crashes in the future.

Ok, no problem. Will invest a bit more time to find out why or at least
to track the problem down a bit.
You can have a look at the corresponding code via the cvs-repo on
http://crosswidgets.sf.net although i'm afraid you won't have much fun
with it ;). The tree (including special model) can be found at
org.Xwidgets.Qt.QtTree, the node used is org.Xwidgets.Qt.QtTreeNode.
Testcase is in org.Xwidgets.examples.TreeTester.
Btw: Crashing jambi is not a big deal, had that already quite sometimes
before, although usually the dumps where more informative ;). Most of
the time crashes were caused by passed/unchecked null values.
Crashdump from right now is attached for those who are interested.
Hopefully i get that bug soon although the dump says that it happens in
some private method.
Best regards

Ok, the dump from the mail before isn't the only problem it seems.
*** glibc detected *** /opt/java6_32bit/bin/java: malloc(): memory
corruption: 0xf7f5c4e0 ***
This memory corruption also happens sometimes, besides that there's a
second crashdump from libc failing to get some fileinfos/malloc some
space it looks. I'm still searching why this may happens, but no idea yet.
To note: i am testing using a 32bit version of java6 on my 64bit linux,
to doublecheck that this is not a problem a teammate tried it using
java5 on his 32bit box, same results.
Best regards

Moin list!
So i tried some more things to track the problem down. First of all i
changed the data used in the tree to simple String/boolean pairs
representing url/isFile. Besides that i did the browsing in some other
way. So no java.io.File is involved anymore. Also i updated to the final
release of java6. No change, still the same. I still get the same
segfaults (libc/malloc(), libQtGui/TreeViewPrivate9viewIndex()) as
before as soon as some node has children, no mem-corruption yet. It
works fine if a node hasn't any children (which at least tells us that
getting the child count works fine, seems like getting the children
using index() and its fellows is probably the problem). Stacktrace is
the same as last times, maybe one of you has an idea what could cause
trouble here.
The only idea i have is that the references in the cpp-part get lost due
to gc since my teammate reported he could open a directory with only 6
items about 7 times now before he got a segfault finally. I'm afraid
that i myself only tried to open bigger directories before since /bin
was right on the top, as was /dev, both having a huge amount of entries.
That behaviour looks kind of randomly since he couldn't open that 6
items directory anymore after some time. He used java5.
I'm happy to test every idea you have ;).
best regards

I've tried a number of different things now on different systems, but I
am unable so far to reproduce crashes. I tried with the tp3 package on
Windows XP and on ubuntu 5.2 and ubuntu 6.0.
If your crashes are caused by dangling pointers to objects that are
collected by the garbage collector it should be possible to 1. Provoke
these by calling System.gc() in a number of places to forcing the gc to
run more often and 2. Avoid these by never letting go of any references,
such as putting them into a List or something. If the crashes go away by
doing this it would indicate that the c++ side is in fact referencing
memory that has been deleted.
I tried approach no 1 on both linux/windows on my old example but was
unable to provoke crashes that way.
I'll get back to you if I notice anything more

Really weird, must be some unchecked code somewhere that lets the jvm
crash all the time. By any chance could you do the same example using
java.io.File? I don't think that this should change anything, but it's
worth a try i'd say.

Well, my code is almost the same as yours, there's just one model-layer
more which abstracts the qabstractitemmodel a bit and i'm using
java.io.File instead of Qt classes. So i also keep references in a
HashMap using their id's as key.
I tried to call System.gc() in some places, besides a notable slowdown
the same shit as before happened.

Well, must have been bad luck then, as already mentioned i opened about
10 layers before the crash occurred. took much more time than my code to
crash ;).

Great, thanks
Just some more things i think i forgot in my previous mails:
index() seems to work fine until the last subitem gets queried. I did a
listing of the directory contents, all items get queried (in random
order though) and indices are created. Then the crash occurs. Would be
interesting to know what gets called next after index() since the
crashdumps are not very informative on that.

Hi Georg,
I just noticed in your crashlogs that your LD_LIBRARY_PATH is set to:
/usr/src/qtjambi-linux-preview/lib
which is the directory structure for the first tech preview. Then in the
load history I see things like:
/space/userSrc/qtjambi-p3/lib/libcom_trolltech_qt_gui.so.1.0.0
It might be the problem.

Na, that's fine. /usr/src/qtjambi-linux-preview is just a symlink to the
latest tp, in this case tp3. i just didn't want to change my command
line all the time so i changed the directory instead ;). To start my app
i copied the appropriate lines from qtjambi.sh with some modifications,
right now i also tried to set the libdir using -Djava.library.path and
drop the PATH setting, no change. But the crash-points get more and more
all the time, i got two different ones now:
libQtCore/Object.userData()
libQtGui/Vector.TreeViewItem.realloc()
