+ add signal showFormulaDialog to QuantitySpinBox in order to indicate whether the formula dialog opens or closes
+ when formula dialog opens then hide the button box in the parent dialog, show it again when the formula dialog closes
Apart for the inclusion of the Analysis functionality, SketchObject has been improved to provide:
- A fast painless deleteAllConstraints() function
- A fast painless constraint group deletion, delConstraints(std::vector<int> ConstrIds, bool updategeometry)
A series of algorithms to detect missing constraints and create them.
Each of the algorithms is divided in different steps for maximum flexibility:
/// There is a first type of routines, simple routines, which work in the following order:
/// Detect - (Analyse) - [Get] - [Set] - Make
///
/// The Detect step just identifies possible missing constraints.
///
/// The Analyse, which is not available for all the routines, operates in detected constraints of the same routine, to
/// look for alternatives. For example, a general pointonpoint detection leads to a search for coincident constraints, which
/// can be later run via Analyse if it is intended to convert endpoint coincidence to endpoint perpendicular and tangent constraints.
///
/// The Get retrieves the result of the analysis as a vector of ConstraintIds, indicating the suggested constraints. This step is intended
/// for enabling the user to check the result of the analysis, rather than applying it. If only applying is intended, this step is not necessary
/// as the Make will operate on the result of the Detect - Analyse directly.
///
/// The Set changes the detected result. It modifies the SketchAnalysis object. It only modifies the SketchObject as far as the SketchAnalysis is changed.
/// It does not apply any changes to the sketch. It is intended so as to enable the user to change the result that will be applied.
///
/// Neither the Detect, nor the Analyse, nor the Get steps modify the Sketch geometry.
///
/// Make applies the constraints stored internally in the SketchAnalysis object.
It includes an automatic constraining algorithm for coincidences, horizontals/verticals and equality:
/// A second type of routines, complex routines, are thought for running fully automatic and they Detect, Analyse and Make.
/// They may also apply a variaty of types of Constraints.
It also includes some helper functions, like autoRemoveRedundants
