How to embed qml-files etc. in executable file? [solved]

ZapB

Sure. Open up the resource file in creator, click the Add->Files... button. In the resulting file dialog navigate to one of the dirs you wish to add. Select all the files in there and click OK. Repeat for the other dir of files.

My full resource file for the project I was talking about looks like this:
@
<RCC>
<qresource prefix="/">
<file>main.qml</file>
<file>Profile.qml</file>
<file>LineEdit.qml</file>
<file>Login.qml</file>
<file>images/clear.png</file>
<file>images/lineedit-bg-focus.png</file>
<file>images/lineedit-bg.png</file>
<file>images/qt-logo.png</file>
<file>images/qtdn-logo.png</file>
<file>images/login-button.png</file>
<file>SimpleButton.qml</file>
<file>images/login-button-shadow.png</file>
<file>images/application-exit.png</file>
<file>RemoteImage.qml</file>
<file>Photo.qml</file>
<file>images/box-shadow.png</file>
<file>SimpleProgressBar.qml</file>
<file>ProgressSpinner.qml</file>
</qresource>
</RCC>
@
Note that I have images as well as qml files in there.

I guess I can use qrc:/ - URLs for the import-path?

e.g.
@import "qrc:/desktop-components/components"@

Can't test this now.

ZapB

Yes I think that should work once you add the components to your resource file.

Hedge

Hmm it seems to work but I'm running into a problem.

The compiler says:
@qrc:/qml/MyProject/main.qml:2:1: module ":.desktop-components.components" plugin "styleplugin" not found @

This is qrc-file:

@<RCC>
<qresource prefix="/">
<file>qml/MyProject/main.qml</file>
<file>desktop-components/components/Button.qml</file>
<file>desktop-components/components/ButtonRow.qml</file>
<file>desktop-components/components/CheckBox.qml</file>
<file>desktop-components/components/ChoiceList.qml</file>
<file>desktop-components/components/components.pro</file>
<file>desktop-components/components/ContextMenu.qml</file>
<file>desktop-components/components/Dial.qml</file>
<file>desktop-components/components/Frame.qml</file>
<file>desktop-components/components/GroupBox.qml</file>
<file>desktop-components/components/HeaderSection.qml</file>
<file>desktop-components/components/Makefile</file>
<file>desktop-components/components/ProgressBar.qml</file>
<file>desktop-components/components/qmldir</file>
<file>desktop-components/components/RadioButton.qml</file>
<file>desktop-components/components/ScrollArea.qml</file>
<file>desktop-components/components/ScrollBar.qml</file>
<file>desktop-components/components/Slider.qml</file>
<file>desktop-components/components/SpinBox.qml</file>
<file>desktop-components/components/Switch.qml</file>
<file>desktop-components/components/Tab.qml</file>
<file>desktop-components/components/TabBar.qml</file>
<file>desktop-components/components/TabFrame.qml</file>
<file>desktop-components/components/TableView.qml</file>
<file>desktop-components/components/TextArea.qml</file>
<file>desktop-components/components/TextField.qml</file>
<file>desktop-components/components/ToolBar.qml</file>
<file>desktop-components/components/ToolButton.qml</file>
<file>desktop-components/components/plugin/libstyleplugin.a</file>
<file>desktop-components/components/plugin/styleplugin.dll</file>
</qresource>
</RCC>
@

This is the start of main.qml
@import QtQuick 1.0
import "qrc:/desktop-components/components"
import "qrc:/desktop-components/components/plugin"@

Ah, you cannot compile a dll into the resource system. I do not think the library loader supports using the resource system. Also it doesn't really make sense to place a shared library inside the binary as it loses any benefit of being a shared library.

I think you'll need to remove your style plugin from the resource system and load that using the method I suggested above with QDeclarativeEngine::addImportPath().

Hedge

Ah! I almost forget that libraries can't be resources.

It works now when styleplugin.dll is inside the .exe-folder.

I also placed a copy of styleplugin.dll inside the folder 'plugins' and added the following line in my main-function

@QCoreApplication::addLibraryPath(QCoreApplication::applicationDirPath() + "/plugins");@

but that doesn't work. What could be wrong here? applicationDirPath() returns the correct location.

ZapB

What category of plugin is it?

Hedge

It's a qml-plugin.

ZapB

In that case I think that you need to use QDeclarativeEngine::addImportPath() as I mentioed earlier rather than addLibraryPath().

Hedge

OK, but that returns an error (I placed it in the main-function)

@QDeclarativeEngine::addImportPath(QCoreApplication::applicationDirPath() + "/plugins");@

@error: incomplete type 'QDeclarativeEngine' used in nested name specifier@

Adding it to the QmlApplicationViewer doesn't do anything

@ QmlApplicationViewer viewer;
viewer.addImportPath(QCoreApplication::applicationDirPath() + "/plugins");@

Also the QtCreator-editor complains that it can't find both imports:
@import "qrc:/desktop-components/components"
import "qrc:/desktop-components/components/plugin"@

You set it solved but i can't see solution.. Could you write me solution?

I think we can't load library in such way. For me problem solution was in modifying qstyleplugin and build rules. If needed I can share the code.

DamianMilo

Could you share code? thanks.
