In order to speed up qml loading, I followed this to compile resources:

https://developer.blackberry.com/cascades/documentation/getting_started/tools/compiling.html

Issue:

 can't build, with error:

Could not find qmake configuration directoryCould not find qmake configuration fileUsing OS scope before setting MAKEFILE_GENERATORmake[2]: *** No rule to make target `assets.qrc', needed by `o.le-v7-g/.rcc/qrc_assets.cpp'.  Stop.

Solution: The tutorial is misleading, the pro file should be :

RESOURCES += qrc-assets.qrc

Question 1:

Is this a way to hide and protect the source code of qml file? If not , how?

I can still see qml source in .bar file.

 Question 2:

I didn't see any effects, do I need to change * to specific file name?

<asset path="assets" dest="assets">

    <exclude name="**/*.qml"/>

</asset>

I also tried to compile resources, but application fail to start. I saw that error in tutorial too, and i corrected that. You dont need to add this line 

<asset path="assets" dest="assets">
    <exclude name="**/*.qml"/>
</asset>

 to bar-desciptor.xml , insteed you need to modify that line, because you already have it. Just modify this line

"<asset path="assets">assets</asset>" to that above, and you will not get resources inside .bar file anymore.

But something else is missing, application cannot start.

I had the same issue. I fixed it by specifying the "qrc:/" prefix when loading my qml.

Change this:

QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);

to this:

QmlDocument *qml = QmlDocument::create("qrc:/assets/main.qml").parent(this);

I changed to QmlDocument *qml = QmlDocument::create("qrc:/main.qml").parent(this);

But:

slogger2 buffer handle not initialized. ../../lgmon_api.c, logEvent(), around line 578!
bb::cascades::QmlDocument: error when loading QML from:   QUrl( "qrc:/main.qml" ) 
  --- errors:  (qrc:/main.qml: File not found)
bb::cascades::QmlDocument:createRootObject document is not loaded or has errors, can't create root

Try including the assets directory in the path:

"qrc:/assets/main.qml"

[xhotkey]

you mean QmlDocument *qml = QmlDocument::create("qrc:/assets/main.qml").parent(this);? it works for this line. But, there's some other error in qml: import "common" bb::cascades::QmlDocument: error when loading QML from: QUrl( "qrc:/assets/main.qml" ) --- errors: (qrc:/assets/main.qml:2:1: "Common": no such directory)

[strobejb]

Theres no magic going on here -

Use QmlDocument::create() as before, but specify the correct path to your qml file. Look at the example I provided above.

[strobejb]

ok I see you updated your question -

Make sure you include all of your QML in your assets.qrc file. I'm using assets-in-subdirectories as well and I can confirm everything is working as you would expect it to. No changes were necessary other than using the qrc:/ prefix

[xhotkey]

I need to manually add each qml file? That's not so smart I think.

Anyway, my qrc file is :

<!DOCTYPE RCC>
<RCC version="1.0">
<qresource>
<file>assets/main.qml</file>
<file>assets/Common/ToolContainer.qml</file>
<file>assets/Common/ToolItem.qml</file>
<file>assets/Common/ToolPage.qml</file>

...

</qresource>
</RCC>

My xml file has:

<asset path="assets" dest="assets">
<exclude name="**/*.qml"/>
</asset>

My pro file ends with:

RESOURCES += qrc-assets.qrc
DEPENDPATH += assets

And I change 

import bb.cascades 1.0
import "Common"

to

import bb.cascades 1.0
import "qrc:/Common"

Still:

bb::cascades::QmlDocument: error when loading QML from: QUrl( "qrc:/assets/main.qml" )
--- errors: (qrc:/assets/main.qml:2:1: "qrc:/Common": no such directory)
bb::cascades::QmlDocument:createRootObject document is not loaded or has errors, can't create root

BTW, should I change

imageSource: "asset:///images/icon_vibro.png"

to

imageSource: "qrc:/asset/images/icon_vibro.png" ?

[strobejb]

Yes: you need to add every QML into the <qresource> section. But it is trivial to create a python script that auto-generates this file for you.

No: don't change anything else - everything will work as expected from within the qml files themselves, unless you have instances where you are not using the asset:// selector. In those cases, make sure you specify the full filepath with the file:// selector

i.e.
imageSource: "asset:///images/icon_vibro.png" // OK

imageSource: "images/icon_vibro.png" // NOT OK - change to:


imageSource: "file:///accounts/1000/...../images/icon_vibro.png"

.. or whatever the full path to your app is.
