Where can I find (and modify) the source code for QT quick elements
-
Re: Where can I find the source code of the Qt Quick elements ?
The above is a very old thread about this, but I'm guessing this have changed in the past ten years, so starting a new thread.
I'm learning QML, and would like to read and make experimental edits to the source code of the elements I'm using -- starting with ComboBox. My QT install is at ~/Qt5.15.2/. In my Qt Creator project, all of the paths (Qt5Core_DIR, Qt5Quick_DIR, etc), point to paths beneath ~/Qt5.15.2. There are dozens of files called ComboBox.qml. Some of them are pure QML, some of them use QtQuick.Templates, which I believe are C++ files.
Questions --
- Among the dozens of ComboBox.qml files in my installation, how can I find the actual sources being used for my application?
- Once I identify the correct sources, can I simple edit them and see changes reflected after I build my app, or do the QML files get compiled cached somewhere?
- Is there documentation I can look at which will answer these questions?

Gitorious is long gone. Use https://github.com/qt/qt5 or https://code.qt.io/cgit/ instead. @SGaist's suggestions to download via the website or installer remain valid.

Ignore the versions in the Qt Creator directory.
<Qt version>/<compiler>/qml/QtQuick/Controls/ComboBox.qml is the QtQuick Controlls 1.x version.
<Qt version>/<compiler>/qml/QtQuick/Controls.2/*/ComboBox.qml are implementations of various styles. QtQuick.Templates provide non-visual structure for the style implementations to build on.

See above.

Editing in place will probably work. Defining a custom style is a better idea.
- Is there documentation I can look at which will answer these questions?
https://doc.qt.io/qt-5/qtquickcontrols-index.html is a user level guide for Controls.
https://wiki.qt.io/Main goes into more detail about modifying Qt.
https://qmlbook.github.io/index.html is an excellent introduction to using Qt and QML. -

https://qmlbook.github.io/index.html is an excellent introduction to using Qt and QML.@jeremy_k Thanks so much for your reply! Much appreciated. If I understand correctly, there are actually two combobox.qml files which are used to create the ComboBox type, the main one under Controls, and then a style-related on under Controls.2. Is this correct?

@Morgan-Liu-Packard What I wrote above doesn't seem to be true. It looks to me like <Qt version>/<compiler>/qml/QtQuick/Controls/ComboBox.qml is the 1.x version (docs here), and <Qt version>/<compiler>/qml/QtQuick/Controls.2/ComboBox.qml is the 2.x version (docs here).
