This patch fixes crashes that we've noticed during migration from Qt5 to
Qt6 in recent months.
If you select items in a tree in a specific direction or range (all, or
from bottom to top) and delete them, there is a high change user will
experience a crash in `testStatus` function. This problem arises because
we're getting into use-after-free situation.
Looking at the callstack there are a lot of calls to
`itemSelectionChanged` during deletion, which takes over item creation
after deletion in `TreeWidget::_slotDeleteObject`. This in turn causes
`DocumentObjectItem::testStatus` to be called prematurely when we have
dangling pointers in object map still. `itemSelectionChanged` signal is
being transmitted because the selection range is changing as we're
constantly deleting and readding certain items.
Previously there was `blockSelection` call during deletion, but it turns
out the signals can still be emitted even AFTER we delete the item. This
had to somehow change between Qt5 and Qt6. So, to be safe, move the
signal block for selection before the obj deletion loop to be sure we
won't retransmit this signal during an uncertain state.
As the title says - since there is pending PR for better SoDatumLabel
constraints interactivity, this patch now prioritizes geometry lines
over constraints, so constraints will be rendered below lines.
This patch changes rendering order of constraint lines to be below
geometry lines, so now selection and rendering will be prioritized for
geometry lines instead of constraints.
This is done by changing depth buffer values and removal of SoAnnotation
node which was disabling depth buffer checks on constraints at all.
- Fix comment for mid-point
- Use in-class member initializers instead of constructor
- Remove redundant default constructor (got redundant after initializers)
- Made comments doxygen compatible
Regressed from previous behavior - there was Arch's refactor and the
base element that `SectionPlane` was inheriting from was
`App::FeaturePython`, not `Part::FeaturePython`. This changes a lot, since
`Part::FeaturePython` has predefined color (black in this case), which
later on - during property set of `SectionPlane` in properties caused
skipping of preferred setup of color.
* Add input hints to fillet and chamfer tools
* Add hints to trimming tool
* Add hints to splitting tool
* Implement hints for extend tool
* Add hints to external geometry
* Add hints to Carbon Copy tool
* Hint updates to align with developer guidelines
* change "click to set" to "set" per PR comments
* Use enum (or declare one) to be type safe per PR comments
* For "trivial" one-step / one-state tools, refactor with direct hint return rather than using declarative / table pattern.
* Refactor hint tables initializers with C++20 features per PR feedback
- Use designated initializers (.state = , .hints = ) for clearer structure
- Add 'using enum Gui::InputHint::UserInput' to eliminate repetitive prefixes
- Applied to DrawSketchHandlerExtend and DrawSketchHandlerFillet
* Refactor Splitting tool hint implementation with direct return (trivial) pattern
* For fillet change "vertex" to "point" per PR feedback
* Change hint to "pick location on edge to split" per PR feedback
