[this one sucks] Application works only in specific folder, exits silently in another folder

Could you show us the contents of your resources.qrc file?

Hedge

Yeah, no problem.

Hi Hedge,

this

@
<qresource prefix="/">
@

is not needed, it could be

@
<qresource prefix="">
@

Hedge

Thanks for the suggestion. That doesn't fix the problem though.
Do you have other suggestions?

This works for me:

------ main.cpp ------
@

#include <QtGui/QApplication>
#include <QDeclarativeView>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QDeclarativeView view;
view.setSource(QUrl("qrc:/qml/QMLwithResource/main.qml"));
view.show();-

return app.exec();

}
@

------ qmlresource.qrc ------
@
<RCC>
<qresource prefix="/">
<file>qml/QMLwithResource/main.qml</file>
</qresource>
</RCC>
@

Watch out if you use the autogenerated qmlapplicationviewer, it has a setMainQmlFile which takes a QString as argument. On the Mac the path is adjusted to look into the AppBundle.app/Contents/Resources directory. You might want to adjust that class to take a QUrl as argument.

Hello Volker. The problem must be the:

@import "desktop-components/components"@

inside the main.qml file. It works without it (I replaced the whole GUI with just a rectangle).

goetz

It works for me too (all in resources, no access to files on the disk):

@
<RCC>
<qresource prefix="/">
<file>qml/QMLwithResource/main.qml</file>
<file>qml/QMLwithResource/parts/FancyText.qml</file>
</qresource>
</RCC>
@

In main.qml I have :

@
import QtQuick 1.0
import "parts"

Rectangle {
width: 360
height: 360
Text {
id: ttt
text: "Hello World"
anchors.centerIn: parent
}
Text {
id: blurb
text: "blurb"
anchors.top: ttt.bottom
anchors.horizontalCenter: parent.horizontalCenter
}
FancyText {
id: ft
anchors.top: blurb.bottom
anchors.horizontalCenter: parent.horizontalCenter
}

MouseArea {
    anchors.fill: parent
    onClicked: {
        Qt.quit();
    }
}

}
@

FancyText.qml is

@
import QtQuick 1.0

Item {
id: fancyTextId
width: 100
height: 62
Text {
id: fancytextid
text: "This is a fancy text"
}
}
@

You can add this snippet to your main.cpp, at the beginning. It shows you in which paths the qml files are searched for:

@
QByteArray data = "1";
qputenv("QML_IMPORT_TRACE", data);
@

Hedge

@ QByteArray data = "1";
qputenv("QML_IMPORT_TRACE", data);
qDebug() << data;@

Output is "1" still.

You've spend so much time with my project.
I hope I can make it to the Qt Summit and spend a beer.

Now that you already have a test-setup why don't you try the desktop-components http://qt.gitorious.org/qt-components/desktop (release-build + move exe to another folder).

I smell there's some bullshit going on there because when I run the release-build exe through Qt's debugger there occurs an error within styleplugin.dll .

Hedge

bump New day, new ideas?

goetz

Sorry, I was too busy today. I didn't forget your issue - stay tuned :)

Hedge

This wasn't specifically referring to you.

I'm tuning the OSX-version in the meantime.
Oh btw. I don't have this problem on OSX. I can put the app anywhere and it works fine.

Hedge

Ok I did another try.
This time I added ALL files of desktop-components to the qrc-file (even the dll which isn't supposed to be there) but still no luck.

It's clearly the line import "desktop-components/components" in main.qml which make the application crash.

goetz

DLLs cannot be loaded from qrc files anyways - it will just bloat the exe. I still need my MinGW environment to check on a Windows box :)
