[SailfishDevel] Python and Qt Widgets development possible?
Hi! Until now I have been using PySide to write Qt Widgets applications that were running fine under Windows and Maemo. With some if/else I got native look feel on both platforms. Now I've tried the same with PyQt5 on Sailfish OS and the application looks like a Windows application and even opens new windows when I e.g. open the menu. Unfortunately it seems that QML is the only way to get native look and feel. Am I right? Switching to QML/Qt Quick seems a major effort and especially, it is very un-pythonic to use this mixture of two languages. Even when I switch, it seems that there's quite some effort to stay compatible over multiple platforms as you more or less have to use Silica components on Sailfish OS and on the other hand I won't gain usability on a mouse based platform like Windows. With Maemo I had the impression that it was quite easy to port any GUI application and get at least a reasonable UI. Seems that this is not true with Sailfish OS any more. You have to choose between all or nothing... Regards, Dietmar ___ SailfishOS.org Devel mailing list
[SailfishDevel] Binding weirdness on Jolla device after deploy with screen locked
Hi all
I have come across some weird behaviour on the Jolla:
Bindings don't seem to work immediately after an app has deployed when
the screen is locked.
To demonstrate this I have created the code snippet at the end of this
mail. To reproduce, create a default Sailfish project, paste the code
into FirstPage.qml.
My code has:
1) an Item dummy with an enabled property bound to applicationActive.
2) a BackgroundItem with an enabled property bound to dummy.enabled
3) a Label in the BackgroundItem with with text property bound to
dummy.enabled
When the app is active, the label should display Correct Label
However, if the app is deployed when the screen is locked, on
unlocking and activating the app
the label text shows Oops Wrong label even though console.log output
suggests that the text has changed to Correct Label.
Also, when the backgroundItem is clicked, the highlight colour is not
shown (but an onClicked event is generated).
The app behaves as expected (label correctly displayed, highlight
colour shown) when:
a) The app is pushed to the left, and then reactivated,
b) The app is deployed while the screen is unlocked (immediately shown
fullscreen),
c) The app is opened from the app icon direct on the Jolla,
d) The app is deployed to the Emulator.
Grüsse
Chris

Hi Dietmar Zitat von Dietmar Schwertberger maill...@schwertberger.de: Switching to QML/Qt Quick seems a major effort and especially, it is very un-pythonic to use this mixture of two languages. There is only one language here, QML, which is an extension of javascript. Qt Quick is a set of components used by QML. This component set is further extended by the Sailfish Silica component set. I did not find QML itself that hard to learn, and there are lots of examples and tutorials on the interweb. The mix of 2 languages comes when need to do some heavy-lifting and have to fall back to C++. Having said that C++ and QML are well integrated.

Hi Ove That's pretty much the behaviour I get, and the swipe to multitasking and back fixes things.

You should not rely on it beeing there forever. In a future update we'll provide middleware to handle SD-card related functionality (informing if SD-card is present, and at which path, notify about removal, ...); until then using the SD-card from your application is not officially supported, and if you do use it, you need to take care of SD-card discovery and error handling if the SD-card gets removed by yourself. Also, I want my users to be able to put data (aviation maps+more) on the SD card via a USB connection. Currently there is no access via USB (just the home is available).

So Jolla get's punishment, because a user want's to use HIS Contacts, because they are fetched from 3rd party service, the user put HIS contacts?! - Wow strange. But making added by hand contacts is/could be possible? And what about if the user have to accept that a app wants to use his contacts from 3rd party?
