RE: How to get kinetic scrolling working using Qt creator
Daniil,
Yes, both horizontal and vertical scrolling are working with your code. Now how
do we get this to work in my case? :)
In my case, I have a scrollAreaWidgetContents (QWidget) 798 x 476 added to
scrollArea. I can not resize this object using Qt creator. Even if I try to
change the ui header file directly outside Qt creator, scrolling is not
enabled. The group boxes which are added to scrollAreaWidgetContents have a
combined height of more than 500.
I have no clue why this doesn't work, unless groupboxes and/or form layouts
does not support scrolling.

{
QApplication app(argc, argv);
QPixmap pixmap(1000, 1000);
pixmap.fill(Qt::green);
QLabel *label = new QLabel;
label->setPixmap(pixmap);
QScrollArea *scroll = new QScrollArea;
scroll->setWidget(label);
QMainWindow win;
win.setCentralWidget(scroll);
win.show();
return app.exec();
}

And my point is that really, if you are performing blocking operations in the UI thread, you're probably doing it wrong - and this is one of the symptoms you'll get as a result. Others can include but are not limited to nothing responding at all to presses, visual updates performing slowly (or not at all) for e.g. progress bars.. It's possible to work around it, but that's compounding more wrong on top of it. Users don't normally tend to like unresponsive UIs, long operations that they can't cancel, etc. In short, I'm pointing out that there is probably a better way to solve this: by using an asynchronous operation, and cancelling the progress indicator when the callback returns, or performing the slow operation on a thread, and letting the GUI thread do what the GUI thread does best: update the GUI. An example of the former (asynchronous operation) can be seen at http://gitorious.org/~w00t/qfacebookconnect/facebrick/blobs/master/src/newsfeedpostview_addcomment.cpp - I'm also happy to explain this (both the concept and the example code) in more detail to anyone who wants on IRC or mail.

Hi Felipe!
This is not related to window manager as it's a separate process.
Simply changing
attributes is done through event mechanism.
Consider this application:
#include
int main (int argc, char **argv)
{
QApplication app(argc, argv);
QMainWindow win;
win.show();
QMessageBox::StandardButton reply;
reply = QMessageBox::warning(&win,
QObject::tr("Title"),
QObject::tr("Message"),
QMessageBox::Yes | QMessageBox::No);
if (reply == QMessageBox::Yes) {
win.setAttribute(Qt::WA_Maemo5ShowProgressIndicator, true);
app.processEvents();
sleep(5);
win.setAttribute(Qt::WA_Maemo5ShowProgressIndicator, false);
}
return app.exec();
}

Re: How to force landscape mode in Qt 4.6.2?
also I think you need to setAttribute(Qt::WA_Maemo5AutoOrientation, true) on a QMainWindow to set that to landscape afterwards.

Re: Strange problem with Maemo5ShowProgressIndicator
Hi Felipe!
This is not related to window manager as it's a separate process.
Simply changing
attributes is done through event mechanism.
Consider this application:
#include
int main (int argc, char **argv)
{
QApplication app(argc, argv);
QMainWindow win;
win.show();
QMessageBox::StandardButton reply;
reply = QMessageBox::warning(&win,
QObject::tr("Title"), QObject::tr("Message"),
QMessageBox::Yes | QMessageBox::No);
if (reply == QMessageBox::Yes) {
win.setAttribute(Qt::WA_Maemo5ShowProgressIndicator, true);
app.processEvents();
sleep(5);
win.setAttribute(Qt::WA_Maemo5ShowProgressIndicator, false);
}
return app.exec();
}
Thanks, Daniil.

Re: Something quite amazing (and simple): QtContacts 1.0 on qt Nokia SDK beta
Hi, ext Felipe Crochik wrote: I don't know if this was just a happy accident but I just compiled my application using Qt Contacts 1.0 mobility library on qt sdk beta and was able to have it deployed to my phone automatically. As most using qt sdk probably knows the mobility packages included with the sdk are not release 1.0. After asking around and looking for a solution I decided to just mess around and try... maybe there is a better way but I failed to find it. the newest MADDE update (0.6.72) has the 1.0 Qt Mobility libraries. You can configure your QtCreator to use that one [1]. 1. http://wiki.maemo.org/MADDE Daniel IMPORTANT: I don't recommend...if you can...just wait for the official release :) In case anybody is feeling adventurous the steps were quite simple: 1. Copy the headers for the contacts module from scratchbox to C:\NokiaQtSDK\Maemo\4.6.2\sysroots\fremantle-arm-sysroot-1014-slim\usr\inclu de (in order to find out which ones I needed I compiled just the contacts module from qt mobility on scratchbox and installed it to a blank folder - I can provide the list of files) 2. Copy the "library" (libqtContacts.so*) from your scratchbox (or device) to C:\NokiaQtSDK\Maemo\4.6.2\sysroots\fremantle-arm-sysroot-1014-slim\usr\lib Not sure if this applies to any other environment (than windows) and/or will work for any other mobility package but for now it seems to have worked for the contacts module at least on windows. It does make life MUCH easier... too bad it took me all this time to try it. Please be aware that I don't have any reason to believe (and neither should you) that this will not cause some unexpected problems ... All that I know is that apparently worked just for one application I tested.

libosso connects to both D-Bus daemons: the system and session bus.
run-standalone.sh just defines the environment variable so that it knows
how to connect to the D-Bus session bus (there could be many of them).
You don't need that script when you develop in the device (environment
is defined there at login time). Just ask if you have questions, I
happen to know something about the horrible libosso :)
