Cool, thanks!
I've replaced it with a custom colour chooser from git already :)

Aha – you nailed it!
Yes, presently the Qt Quick Dialogs do not style in the same way as
the compile time styles do for the rest of Qt Quick Controls.
Unfortunately these are still using File Selectors under the hood to
pull out the correct QML at run-time according to the style that is set.
Therefore it is necessary to include all styles’ QML files for the
non-native dialog implementations whether you are going to use them or
not – simply because there is no current way to let the compiler know
this in advance.
Qt are aware of this and I understand that Mitch and Fabian have been
working on something of a proper solution which may help in the long run:

Hi,
so I tracked it down to the import of QtQuick.Dialogs. When I import
it, the size of the wasm file increases from iirc 34mb to 40, and my
debug output shows the fusion and imagine style (plus some others). It
makes sense as there are a bunch of native dialogs in there. though i
don't know whether they are usable via wasm. In case somebody is finds
this, do a full rebuild after removing dialogs. Seems like caching is
at work there.
I don't know whether this is a bug or not. These styles don't show in
native compilation on linux. and it's certainly surprising, that
adding a colour dialogue adds 6mb on your wasm file.
should i report it as a bug?
thanks for the answer, it helped understanding the issue :)
cheers, Adam

Hi,
I'm using Qt 6.6.1 and cmake.
I have imports like this:
import QtQuick
import QtQuick.Controls.Material
import QtQuick.Layouts
import QtQuick.Dialogs
at one point i'm also importing QtQuick.Controls.Universal.
i also verified that at no point i'm importing QtQuick.Controls
alone. i'm linking in CMakeLists.txt via:
target_link_libraries(alpineapp PUBLIC nucleus gl_engine Qt::Quick
Qt::QuickControls2 Qt::Charts) // Charts removed on my other
workstation with no change.
this is the CMakeLists.txt i'm using (along with the rest of the
project:

with automatic builds at

interestingly, on a desktop build, only commonstyle and macstyle
are imported (no material style, but it's there in the app).
I also just tried the calqlatr example, replacing the only import
of QtQuick.Controls i found with QtQuick.Controls.Material and
adding my debug code for printing styles. The result is import of
the imagine, basic and fusion style, but surprisingly not material.
I'll try to setup a minimal example on tomorrow.
Thanks, Adam

Hi Adam,
How are you using the styles in QML?
Are you importing QtQuick.Controls (only) or are you using
specific style imports?
Which version of Qt? CMake assumed?
Assuming the latter and at least Qt 6.2, CMake will only build
in the libraries it absolutely needs. But for this to be the
case, it needs to know what it needs. Using just import
QtQuick.Controls relies on run-time style selection (for which
there are different ways to select, all nicely documented). In
this case the compiler cannot know in advance which to
include, so it has to bring in all of them just in case you
run post-build with a different style however it selects it.
For compile-time style selection, you import
QtQuick.Controls.Basic/Fusion/Universal .... being specific.
Or.. you can use your own style and not Qt Quick Controls at
all (albeit it is sometimes hard to not use some of its nice
helper types). In this case the compiler only compiles what it
needs and there would be nothing in CMake that generates a qrc
file with all the run-time style options.
Very obviously this is not your observation so more details on
your Qt Quick Controls usage and how you choose your styles
and any relevant CMake project/module info would be helpful
for someone here to better understand your specific case and
more importantly, if there might be a bug.

*Subject:* [Interest] unnecessary files in qrc system in
webassembly
Hi,
I'm building a QML app for WebAssembly using CMake. When
debugging
something else, I printed all files that are in the qrc
system. Doing
that, I saw, that the macos, universal and fusion styles are all
compiled in. There are also a bunch of icons for file
dialogues etc. I'm
not using them, and they increase the binary (wasm) size.
Is there any way to remove them?
Thanks, Adam
