Xenakios	looks non-native in xp?
RLa	a bit
RLa	anyway, i have set my own colors and fonts for the app so it looks now more-less same on both systems
tmorton	I'm trying to use qSort() to sort some QPoints. However, the order of the QPoints depends on data (variables) in my class, so my lessThan function can't be static.
tmorton	However, I can't seem to figure out how to pass a pointer-to-member to qSort
tmorton	any ideas?
dhrosa	tmorton: you could make a functor object
dhrosa	wait no
dhrosa	wait yes
Xenakios	implement operator <?
dhrosa	make the functor object havea  MyClass member, and have implement operator() to be your comparator
Xenakios	ah forget it...
dhrosa	Xenakios's idea works too if the list isn't of pointers
Xenakios	if he needs to sort according to some condition inside his own class
tmorton	Xenakios, yeah, that's what i need
Xenakios	i don't think operator < would work?
Xenakios	that's actually also a question i've been thinking
tmorton	hmm
tmorton	that seems like it might work
Xenakios	sometimes it'd be useful to sort things in different ways
Xenakios	and not do a hack like "the < operator looks in the objects it compares for a sort mode member"
tmorton	hmm, do you guys see a reason why implementing operator()< wouldn't work?
tmorton	oh, wait
tmorton	i'd need to implement it in the QPoint class
tmorton	so yeah, that wouldn't work
dhrosa	yeah.... the functor object might be better in this case
tmorton	i'll give that a shot
tmorton	hmm, but how do I get the sort information from my class to the functor?
tmorton	can i pass a pointer into the constructor or something?
rohanpm	tmorton: std::mem_fun , std::bind1st
rohanpm	there's an example in the boost docs which should be applicable here too, http://www.boost.org/doc/libs/1_35_0/doc/html/function/tutorial.html
dhrosa	tmorton: if you want
rohanpm	just search for bind1st
dhrosa	your choice on hwo to imeplement it
tmorton	rohanpm, thanks, mem_fun looks like it might work
jonrafkind	whats the best way to draw a border around a widget
dhrosa	jonrafkind: a QFrame perhaps
jonrafkind	hm ok, strange that qframe doesnt let you change the color
Jick	I'm trying to get favicons to work in my QWebView. Right now they ALL display the same blue globe icon instead of the proper icon for each site. I read that I need to set iconDatabasePath in the QWebView's settings correctly. I have tried setting it but nothing seems to work. I even looked at the source code for the demo browser and Arora and my code is just like how it is for those two apps but its still not working. Nomatter what I try to set
KBHomes	So, has anybody had any success using Phonon with QNetworkAccessManager?
KBHomes	What I'm currently doing is on the readyRead() signal, I'm writing to a QBuffer
KBHomes	And on the first readyRead() I'm emitting a signal that has the QBuffer in the parameter
KBHomes	And the main window picks up the signal and does mediaObject->setCurrentSource(buffer); and then mediaObject->play();
KBHomes	But it doesn't seem to do anything
KBHomes	Moreover the stateChanged() signal of MediaObject isn't emitted
machtfuernacht	Hi
dhrosa	hi
machtfuernacht	I try building qtoctave on Windows and I have some problems with libQtUiTools.a
machtfuernacht	http://pastebin.com/xUwrQq3h
machtfuernacht	nm says, that libQtUiTools.a has no danymic symbols. I think that this is the problem. But I have no idea how to fix it.
JamesAstro	I can't seem to compile any of the examples that ship out with qt4 for windows but i can compile my own projects fine. I used the installer so id on't know what could have gone wrong. Any one know what might cause this?
marloshouse	JamesAstro: how are you  compiling, from command line or from the qtcreator?
JamesAstro	qtcreator
marloshouse	what error are you getting
JamesAstro	shoot. i didn't copy it down and it is uninstalling so i can reinstall it
JamesAstro	it'll be a sec
KBHomes	Strange, if I wait for the entire download to finish, and then play it from the buffer, it works then.
KBHomes	But not before it's finished.
machtfuernacht	Anyone an idea for ma UiTools.a problem?
dhrosa	machtfuernacht: that's not the problem
rohanpm	machtfuernacht: libQtUiTools.a is not _supposed_ to have dynamic symbols
rohanpm	.a files are static libraries
rohanpm	machtfuernacht: libQtCore4.a should provide _imp___ZN7QObject16staticMetaObjectE , can you check for that?
rohanpm	don't give the -D option to nm
machtfuernacht	yes there it is
machtfuernacht	k I had to reorder the libraries.
machtfuernacht	seems to compile now.
shadewind	if I run a member function using QtConcurrent::run(), is it legal to emit a signal from this member function?
JamesAstro	For some reason Qt is picking up visual studio libraries as a lib path. how do i remove this?
JamesAstro	using QtCreator
JodaZ	hmm, i am having a problem here, qt is rendering characters of the fallback font in a different size than the normal ones
machtfuernacht	Is it possible to get a list of the dlls that the program needs?
JodaZ	various
dhrosa	machtfuernacht: ldd on linux
dhrosa	ldd might work on OS X, there's also otool for OS X
dhrosa	dependency walker on windows
JodaZ	the problem is with dynamic linking
machtfuernacht	thx dhrosa dependency walker did it
JamesAstro	does any one know how to not allow qt from including from vc++ include folder?
JamesAstro	it is causing problems with compiling only the example projects
JamesAstro	any one?
rohanpm	JamesAstro: are you sure qt is introducing the dependency?
rohanpm	wouldn't surprise me if the MSVC compiler is automatically adding these directories to the include path
JamesAstro	hmm i suppose there was simple and wiered fix to it
JamesAstro	i had to clean the build files and rebuild them
JamesAstro	that fixed it
zeke	how can I prevent an user from right clicking on the main window and closing my docks and toolbars?
zeke	except for certain toolbars
elfMobile	does QT have a widget like this?   http://www.adobe.com/products/photoshoplightroom/images/volume_management_325x200.jpg
zeke	elfMobile: I think you have to make your own
elfMobile	zeke, I'm not talking about look / feel
elfMobile	I don't know what you'd call those things, expandable regions I guess... there is nothing like that in Qt?
special	progressive disclosure is the technical name
special	nothing built into Qt, but it would be easy to create
zeke	I think there is something like that in KDE or it's a created one because I see it in KDevelop
special	the functionality of it is trivial, the only hard part is deciding how it looks
zeke	blah I really hope this bug gets done: http://bugreports.qt.nokia.com/browse/QTBUG-9615
special	heh
zeke	well I'm trying to implement my own. My implementation is good, just i need those notifications else I'll have to reimplement all of it myself
zeke	or completely just start over from scratch again
special	could always write it yourself and merge request
zeke	that's what I'm doing right now ;)
special	ah
zeke	well for my application ;)
zeke	well see the problem is, it was requested so much from what I've seen, they just kept push it to the next release and then just denying it
Xenakios	ouch...i didn't realize dockwidgets have those limitations >_<
zeke	Xenakios: yeah they do
Xenakios	i hope i won't bump into those anyday soon
zeke	I didn't notice them until I needed them
special	dockwiget is pretty limited and not very attractive with most styles
special	it does need some love
JamesAstro	why use threads when yo ucan use qtConcurrent? what is the down side?
special	JamesAstro: threads are lower level
special	you get far more control over what happens and how
special	and sometimes the concurrent API can be clunky
special	all depends on what you're doing
Xenakios	QtConcurrent is hard with stuff like progress notifications, cancelling. not very suitable for backround tasks that should always be running
zeke	Xenakios: special: here is my video of my docks. http://www.akiirc.org/aki_newshell.ogv
zeke	I fixed the bugs in that video ;)
Xenakios	in other words, QtConcurrent is suitable for tasks that run and end quickly, with no need for progress reporting/cancelling
zeke	but knowing, my bug report will probably get pushed for next release like 3 times then forgotten about
JamesAstro	ohh i c. Well my situation is this: i am working on a Gui based server and what happens is that a client connects and sends a string and then disconnects. But there are many clients, so i was wondering if i should call a QtConcurrent for every new client.
special	no
special	you don't need a thread per socket, in the vast majority of server situations
JamesAstro	yah?
JamesAstro	so single thread it?
special	Qt's sockets are designed to be used asynchronously
Xenakios	zeke: damn...autohiding docks...yeah...those would be useful...or neat...or something
Xenakios	it's like something that would be "nice" to have but too much pain to implement from scratch :P
JamesAstro	special: but what happens is that i need to update the GUI based ont eh information recieved by the client
JamesAstro	hmm
special	if there is no expensive computation required on your information, you can even run it all out of the main thread
special	if not, one thread for sockets and one for GUI
zeke	Xenakios: what you like how I did it so far?
special	beware of threading issues.
JamesAstro	ic
Xenakios	zeke: i guess it's ok ;)
JamesAstro	thanks :-) this makes me fool lighter
special	but one per socket is a waste of resources
JamesAstro	*fell
JamesAstro	*feel :p Thanks alot
zeke	Xenakios: maybe if I ever get mine finish, I will attempt at cloning a Qt branch and try adding it to Qt itself. But I have no guarentees I will understand Qt's code ;P
zeke	not fond of qmake
zeke	:P
zeke	but more than likely it'd get accept in KDE before Qt
zeke	which my app is based on KDE :P
Xenakios	:-/
zeke	what
Xenakios	well i don't use KDE :P
zeke	i do, and KDE helps alot where Qt alone doesn't
vector_xyz	I am using Qt Webkit to display Images it all works well but some images that are giant take time to load even tho they all are on the local filesystem...
vector_xyz	is there a way to preload an image in C++ via QPixmap or so and then pass that to Webkit
vector_xyz	to display it inside <img src... />
Xenakios	why do you think it's the loading step that's slow?
Xenakios	perhaps webkit just is slow to display images?
vector_xyz	how do i improve it :) to be super-fast :)
vector_xyz	especially if an image is on local file system
guest356876	qtwebkit doesn't seem to support .ico files by default. is there any way to make it support them? like maybe a plugin or something? although I'm not sure how plugins work or anything.
zeke	ico images are horrible
zeke	you can make a qtwebkit plugin
guest356876	the only reason I need them is because I have a qwebview that has a list of websites and I want to display the favicon of each website next to each site. since everyone does favicons in .ico format I need to be able to display them.
guest356876	so how exactly do qtwebkit plugins work? how would I make a plugin for .ico support?
JamesAstro	does qt provide a mechinism to issue system calls and return the output? without manually writing and reading from the filesystem?
Xenakios	uh system calls? like calling the OS native API from code?
Xenakios	there's nothing in Qt stopping you to do that
Xenakios	just need #ifdefs or something for crossplatform heh
Xenakios	on the other hand if you mean start up another process, and wait for it to finish or produce some output, then QProcess
rohanpm	JamesAstro: huh?  what kind of mechanism do you need Qt to provide for that?
tyfon	http://doc.trolltech.com/4.6/qprocess.html
tyfon	i think he's thinking about something like that
rohanpm	JamesAstro: ok, "system call" has a special meaning that you might not have been aware of
rohanpm	http://en.wikipedia.org/wiki/System_call
zeke	how can I prevent an user from right clicking on the main window and closing my docks and toolbars?
zeke	except for specific ones
Xenakios	tell them to apply superglue to their right mouse button :P
Xenakios	or buy a Mac...heheheheheheh
JamesAstro	yes sorry my mistake for not being clear i was talking about some kind of wrapper for System() function
Action: zeke slaps Xenakios
zeke	wow I never knew about QList::value()
zeke	anyone remember the function to get the widget the the current cursor position?
zeke	at the*
JamesAstro	nop
special	zeke: QCursor has the position, and you can use QApplication::widgetAt
JamesAstro	The wieredst thing is happening to me. I have a class declared and implemented. I have a new instance of it and QtCreator recognises that it is a lagit type but during compile it says that it hasn't been declared in t his scope? what is going on i have it included
zeke	special: thats it thank you
Nazzy	hi, I want to use QTestLib to test a C shared object library... anyone know where I can info relating to this?
Nazzy	or is it going to work straight out?
zeke	!rtfm QTestList
qtassistant	zeke: Qt 4.6: QTextList Class Reference - http://doc.qt.nokia.com/qtextlist.html
zeke	!rtfm QTestLib
qtassistant	zeke: Qt 4.6: QTestLib Manual - qtestlib - http://doc.qt.nokia.com/qtestlib-manual.html#qtestlib
zeke	Nazzy: ^^
zeke	read that
zeke	Nazzy: will you be using it only for that single C library and not for a Qt application?
Nazzy	yup
Nazzy	bit of a waste, I know
zeke	Nazzy: you might want to check cpptest or cmake's test
zeke	if you are not using it for a Qt application (waste of dependency and what not
Nazzy	true, though integration with kdev4 seemed a nice point
ToArtist	hi,who knows callingallinnovators???
