Re: [SailfishDevel] LED Flash functionality on a real Jolla
Hi Mohammed thanks. I will try that later (am at work at the moment). I will also need to look into the resource policy engine, as that is new to me. Harbour entry is becoming less and less of a concern for me. My app does too many things that are not considered kosher under the current Harbour rules (sending SMS direct, use of QtContacts, LED access, other Qt Libraries etc.) As an aside, on Harmattan while I got the the Gstreamer route working in developer mode, I never got it working when launching the app direct from the device (and thus chose the QCamera approach). This was probably down to AEGIS, but that should not be a concern on the Jolla.

How are you getting the GL into the QML scene?
From one of the GL examples (Squircle in c++):
glViewport() determining the position (not yet QML) in Page.
main c++:
qmlRegisterTypeSquircle(OpenGLUnderQML, 1, 0, Squircle);
QML:
import OpenGLUnderQML 1.0
Squircle {
SequentialAnimation on t {
NumberAnimation { to: 1; duration: 2500; easing.type:
Easing.InQuad }
NumberAnimation { to: 0; duration: 2500; easing.type:
Easing.OutQuad }

I created a GLItem which allows property connections and sizing so I know where
to draw in the window. I then inherit from this item and render into the
viewport it sets up.
I will have a look at to.
Thanks.

This way the ApplicationWindow (background) doesn't overpaint the OpenGL.
Silica items now nicely and transparantly overlap the OpenGL.

AFAIUI it's slightly lower performance but it does give you total control over
layering your GLES window into your QML.

[SailfishDevel] How to hide pushup menu?
I have PushUpMenu in my app which currently has only one item, and in some situations also that item should not be visible. How can I hide the menu? I tried to set MenuItem's visibility to false, but that lead to weird behaviour; PushUpMenu is still there and empty, but the empty menu can be pushed up about screen height. I also tried to use visible property in PushUpMenu, but that doesn't seem to hide the menu. Disabling the MenuItem could be one option, but as it still shows the item's label it would be a bit misleading for the user in my situation. I would prefer to hide the whole PushUpMenu when there's no items that could be used. -- Tero ___ SailfishOS.org Devel mailing list
Re: [SailfishDevel] LED Flash functionality on a real Jolla
Cool to see that ported, Chris! Are you into porting a tracker such as Gaggle? I am flying a paraglider myself, so would be interested to help. As for LED. I did a flashlight that is currently in the app store. Here is the state of art: 1. Qt Multimedia's torch mode is promised to come, but does not work yet 2. GStreamer way should work and that's what flashlight uses 3. GStreamer library, however, is not allowed to link to in harbour rules, so you will have to provide your own copy of GStreamer 4. Resource policy is needed, but for now I go around it by just stopping LED whenever app is not maximized. That's not exactly correct, but will do for now 5. Note also that you can start LED in a shell by running gst-launch and.. that is actually a workaround flashlight is using while I am figuring out the resource policy and how to provide gstreamer lib with the app. I hope it helps.

[SailfishDevel] App interoperability the Sailfish Way. Particularly sharing between apps. Any ideas on how it can happen UI and API-wise?
Hi there Simplest you case. You are using Tweetian or Friends and want to save a link to some read-it-later service, or share to a not built-in social network (Russian vkontakte or Chinese Weibo) or even to a built-in app such as Messaging or Email. Or you implement a whatsapp client and want to send photos from both local hardrive and dropbox/box/picasa/whatever-the-user-has. To my understanding right now all of these use cases are simply not possible (except for starting email/sms with a given text via openUrlExternally). *What are the Sailfish longer term plans regarding it?* - Android-like intents to provide whichever service to whichever clients + few standard intents? - iOS-like hard coded intents to the known applications that support it? - Something Linux standard?

I can ssh to it when connecting through WLAN though. What I'm doing: - enable developer mode and set-up a password (this one is working since I can connect through WLAN) ; - plug-in USB cable from the computer and choose developer mode connection ; - the settings page tell me that the 192.168.2.15 address is affected to the USB interface. - I setup the computer to attribute 192.168.2.15/192.168.2.255 to the interface on usb0, statically (it's working since ping 192.168.2.15 is responding). - I ssh at this address with nemo as login, it's responding since it proposes to add the hw key to the known host list, and then it's asking for the password, but when I type it, I get permission denied. The password is alright since I can ssh to the device when using WLAN connection. I've tried with a generated password from the interface also but no luck neither. I've tried to find the logs of ssh, but was not able to find them, before they were located in /var/log/auth, but not here. I've tried to look at journalctl output but didn't found anything about rejected connection or ssh. I've tried to google a bit, found the page http://elinux.org/Jolla but still get permission denied.

I have created a bug for it in our bug tracking system. Does the crash happen every time when popping the pagestack while the Map is still panning? How frequently does it happen when not panning the Map? Cheers, -- Aaron McCarthy ___ SailfishOS.org Devel mailing list
Re: [SailfishDevel] Listening to Connman DBUS signals

Hi
this is for sure a beginners question, but I hope somebody can help me to sort
it out. I want to listen to connman dbus events to determine connection
changes
(I'm interested in receiving signal as soon as device connects to particular
WLAN network).
Using some examples I was able to capture dbus events on my KDE desktop
(albeit
not connman related), but same code for SailfishOS does nothing. I guess my
understanding of Dbus or QtBus is bad :)
Here is my piece of code:
#include wifimonitor.h
#include QtDBus
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
WifiMonitor* receiver = new WifiMonitor;
qDebug() Starting dbus monitor;
QDBusConnection system = QDBusConnection::systemBus();
if (!system.isConnected())
{
qFatal(Cannot connect to the D-Bus session bus.);
return 1;
}
system.connect(,
/net/connman/technology/wifi,
net.connman.Technology,
PropertyChanged,
receiver,
SLOT(propertyChanged(const QDBusObjectPath))
);
try something like this:
system.connect(net.connman,
/net/connman/technology/wifi,
net.connman.Technology,
PropertyChanged,
receiver,
SLOT(propertyChanged(QString,QDBusVariant))
);
return a.exec();
}
wifimonitor.h
#ifndef WIFIMONITOR_H
#define WIFIMONITOR_H
#include QObject
#include QtDBus
class WifiMonitor : public QObject
{
Q_OBJECT
public:
explicit WifiMonitor(QObject *parent = 0);
signals:
public slots:
void propertyChanged(const QDBusObjectPath in);
};
#endif // WIFIMONITOR_H
wifimonitor.cpp
#include wifimonitor.h
#include QtDBus
WifiMonitor::WifiMonitor(QObject *parent) :
QObject(parent)
{
}
void WifiMonitor::propertyChanged(const QDBusObjectPath in)
{
qDebug() DBus signal received;
qDebug() PropertyChanged, ObjectPath: in.path();
}
Thanks
Julius
