As a general rule, SwitchActiveProject must be called whenever the active project ought to have changed. This may be confusing when writing UI code. The presenter should take care of this in CloseProject.
This and all related issues should be fixed if the presenter can be made to always figure out what extra steps need to be taken past the actual actions in NewProject and CloseProject.
Schemas describing valid project structure should not be hard-coded in C++. Hard-coding makes them very hard to read and near-impossible to edit.
QtQuick.Dialogs seems to have been removed from QML in Qt 6. This issue is to track finding a replacement.
The code for dispatching undo/redo is general enough that most of it can be handled inside of DigitControl.
Tab group manipulation is mostly procedural and manipulates the QML structure directly. QML contains declarative mechanisms to render lists, and using them will simplify the code and make it more idiomatic.
The current system is a recipe for all sorts of bad.
Related to #48.
When a tab is changed in Anthem, the component that renders the tabs sends a message to the presenter asking it to change the tab. It then emits an event for every existing control or data view in the UI. (!!) This design will lead to a high level of complexity and a lot of unnecessary knowledge of UI implementation details by the presenter.
This can be fixed by instead raising a tab change event in the UI and having controls respond to that event by requesting data from the presenter. This leaves the UI code entirely in the UI and will lead to a system that is much more maintainable.
Anthem probably shouldn't crash if we try to load {"haha": "ha"} :)
There's no way around it: the way Anthem generates and applies its patches for undo and redo is beyond bad. It is cumbersome, highly error-prone, and seems to take the majority of my time when I'm working with data. This must be redesigned. I'm looking at the Command pattern right now - it groups the logic in with the data that describes the logic (the patches). This means the logic for applying the patch and the logic for running the patch in the first place, currently both a web of events and data flow across multiple growing component networks, can be put all in one place, while also doing it all only once.
Perhaps this should have been an obvious solution, or at least one I should have found before now. My lack of experience is no excuse to have not consulted basic design patterns before attempting a naive undo/redo implementation. Better now than later though!
This belongs in #6, but it's already huge, and adding this will require designing a confirmation dialog (1-2 extra days at my current pace).
This issue is for adding the bottom-right resizer as seen in the UI mockups. Panel resize behavior will be iterated on during this process as well.
The current architecture uses two in-memory representations of data, one in C++ and one in JSON. Both are mutated regularly by user actions. The C++ model does not perform serialization; Anthem instead relies on the in-memory JSON representation, stored using rapidjson, for project saving (and soon other tasks as well).
There is a problem here: having two separate data stores means that we must always keep them synced with each other. Any error in properly syncing these will go undetected until the user saves and loads the project, at which point they will load (from JSON, into both the JSON model and C++ model) something different from what they thought they saved (as shown to them from the C++ model).
There's an obvious solution: just remove the JSON model and add serialization to the C++. This will have the added benefit of removing runtime overhead and code clutter.
There is one caveat: with no JSON model, it will be impossible to verify that generated JSON patches are being applied correctly. This can (and should) be easily fixed by adding extra debugging functionality to the engine class to track what the JSON should be as described by the patches generated by the C++. I think I'll have this optionally enabled with a command line flag.
Rapidjson is much faster, but we're not processing gigabytes of data and rapidjson is also an absolute pain to use with Qt.
Right now, they just overflow into the window controls.
I just discovered that parents can be referenced by id, even if they're outside of the current file. This makes it easily possible to avoid using the presenter as a utility for signal plumbing in cases where the presenter has nothing to do with the signal at hand. Yay for proper separation!

QtGraphicalEffects does not work as of Qt 6.
Hi, I've been trying this software today. It does look to compile fine (I didn't see anything wrong while doing so), but it doesn't run when launched from the terminal. The error message is:
QQmlApplicationEngine failed to load component
qrc:/main.qml:80 Expected token `numeric literal'
qrc:/main.qml:80 Unexpected token `>'
qrc:/main.qml:81 Expected token `:'
qrc:/main.qml:81 Expected token `}'
PS: Debian buster up-to-date here
The solution for this is not trivial. For example, the SplitView will only resize the "fill remaining" item, so in some cases resizing the window will cause an invalid UI state, where in other cases it won't. Fixing this may involve factoring out SplitView in some cases.
This happens most easily in debug mode, though you can see some hints that it's not quite behaving right in release. I think the responsiveness of the render loop may have something to do with whether it spirals out of control or not.
Below are the errors generated when this happens. Notice how near the bottom the geometry values seem to be in a feedback loop, getting bigger in magnitude and jumping from positive to negative.

Currently, windows cannot be resized by dragging on the corner. This is a common use-case which should be supported.
Below is a list of atomic UI components that are either partially complete or not yet started. They are in no particular order.
There are a lot that are not listed here, but most are part of a bigger system and ought to be built in that context.
Pattern order should be saved in the project file. It (probably) will be saved as an array of pattern IDs.
From Dom:
_message.toUtf8()returns aQByteArray.QByteArraydefinesoperator const char *, which is used to return its internal buffer from what. But at the end of the return statement, theQByteArrayis destructed, taking its internal buffer with it.
Thus anything reading from the return value of what is reading deleted memory, which is undefined behaviour.
Undefined behaviour includes, among other things, "actually doing what you want it to", which seems to be what is happening in the release build case.
You could try storing aQByteArrayin the exception instead, and useQString::toUtf8in the constructor rather than in what. That way the buffer lives as long as your exception does.
Sometimes the cursor doesn't reset to the regular mouse pointer after resizing. This should be fixed.
Menus may benefit from some minor adjustments and improvements. The following ideas will be evaluated, and implemented if they feel right:
This may make it possible to remove a large amount of duplicated code due to the specifics of the rounded corner implementation with opacity masks.
More items will be added as I think of them.
Project load errors use error text from raised exceptions. These do not build in release.
The Anthem UI tries to separate the UI + display logic from the data manipulation and app logic, but it's not doing a very good job right now. A lot of transient UI state is flowing into the presenter, partly due to some emergent design (not the good kind) during development.
A logic node will be added at the root of the QML tree, and another will be added above the pattern editor. These will handle UI state, and all data will flow through them, further separating functionality into preset categories and hopefully reducing a lot of future technical debt before it happens.
This is a flaw in MouseHelper.
so messy
Along with capturing the mouse and tracking mouse movement, MouseHelper hides the mouse cursor. Doing so causes a desync in every other MouseArea, preventing the MouseAreas from changing the mouse cursor.
