Classes
class	CadConstraint
	The CadConstraint is an abstract class for all basic constraints (angle/distance/x/y). More...

Public Types
enum	AdditionalConstraint { NoConstraint, Perpendicular, Parallel }
	Additional constraints which can be enabled. More...

enum	CadCapacity { AbsoluteAngle = 1, RelativeAngle = 2, RelativeCoordinates = 4 }
	The CadCapacity enum defines the possible constraints to be set depending on the number of points in the CAD point list (the list of points currently digitized) More...

Signals
void	pointChanged (const QgsPoint &point)
	Sometimes a constraint may change the current point out of a mouse event. More...

void	popWarning ()
	Remove any previously emitted warnings (if any) More...

void	pushWarning (const QString &message)
	Push a warning. More...

Signals inherited from QgsDockWidget

Detailed Description

The QgsAdvancedDigitizingDockWidget class is a dockable widget used to handle the CAD tools on top of a selection of map tools.

It handles both the UI and the constraints. Constraints are applied by implemeting filters called from QgsMapToolAdvancedDigitizing.

Definition at line 43 of file qgsadvanceddigitizingdockwidget.h.

Member Enumeration Documentation

◆ AdditionalConstraint

enum QgsAdvancedDigitizingDockWidget::AdditionalConstraint

Additional constraints which can be enabled.

Enumerator
NoConstraint	No additional constraint.
Perpendicular	Perpendicular.
Parallel	Parallel.

Definition at line 66 of file qgsadvanceddigitizingdockwidget.h.

◆ CadCapacity

enum QgsAdvancedDigitizingDockWidget::CadCapacity

The CadCapacity enum defines the possible constraints to be set depending on the number of points in the CAD point list (the list of points currently digitized)

Enumerator
AbsoluteAngle	Azimuth.
RelativeAngle	also for parallel and perpendicular
RelativeCoordinates	this corresponds to distance and relative coordinates

Definition at line 55 of file qgsadvanceddigitizingdockwidget.h.

Constructor & Destructor Documentation

◆ QgsAdvancedDigitizingDockWidget()

QgsAdvancedDigitizingDockWidget::QgsAdvancedDigitizingDockWidget	(	QgsMapCanvas *	canvas,
		QWidget *	parent = `nullptr`
	)

explicit

Create an advanced digitizing dock widget.

Parameters

canvas	The map canvas on which the widget operates
parent	The parent

Definition at line 90 of file qgsadvanceddigitizingdockwidget.cpp.

Member Function Documentation

◆ additionalConstraint()

AdditionalConstraint QgsAdvancedDigitizingDockWidget::additionalConstraint ( ) const

inline

Additional constraints are used to place perpendicular/parallel segments to snapped segments on the canvas.

Definition at line 256 of file qgsadvanceddigitizingdockwidget.h.

◆ applyConstraints()

bool QgsAdvancedDigitizingDockWidget::applyConstraints ( QgsMapMouseEvent * e )

virtual

apply the CAD constraints.

The will modify the position of the map event in map coordinates by applying the CAD constraints.

Returns: false if no solution was found (invalid constraints)

Definition at line 551 of file qgsadvanceddigitizingdockwidget.cpp.

◆ cadEnabled()

bool QgsAdvancedDigitizingDockWidget::cadEnabled ( ) const

inline

determines if CAD tools are enabled or if map tools behaves "nomally"

Definition at line 250 of file qgsadvanceddigitizingdockwidget.h.

◆ canvasKeyPressEventFilter()

bool QgsAdvancedDigitizingDockWidget::canvasKeyPressEventFilter ( QKeyEvent * e )

◆ disable()

void QgsAdvancedDigitizingDockWidget::disable ( )

Disable the widget.

Normally done automatically from QgsMapToolAdvancedDigitizing::deactivate().

Definition at line 1196 of file qgsadvanceddigitizingdockwidget.cpp.

◆ enable()

void QgsAdvancedDigitizingDockWidget::enable ( )

Enables the tool (call this when an appropriate map tool is set and in the condition to make use of cad digitizing) Normally done automatically from QgsMapToolAdvancedDigitizing::activate() but may need to be fine tuned if the map tool depends on preconditions like a feature selection.

Definition at line 1170 of file qgsadvanceddigitizingdockwidget.cpp.

◆ enableAction()

QAction* QgsAdvancedDigitizingDockWidget::enableAction ( )

inline

return the action used to enable/disable the tools

Definition at line 305 of file qgsadvanceddigitizingdockwidget.h.

◆ hideEvent()

void QgsAdvancedDigitizingDockWidget::hideEvent ( QHideEvent * )

overridevirtual

Disables the CAD tools when hiding the dock.

Reimplemented from QWidget.

Definition at line 204 of file qgsadvanceddigitizingdockwidget.cpp.

◆ keyPressEvent()

void QgsAdvancedDigitizingDockWidget::keyPressEvent ( QKeyEvent * e )

overridevirtual

key press event on the dock

Reimplemented from QWidget.

Definition at line 1003 of file qgsadvanceddigitizingdockwidget.cpp.

◆ lineCircleIntersection()

bool QgsAdvancedDigitizingDockWidget::lineCircleIntersection	(	const QgsPoint &	center,
		const double	radius,
		const QList< QgsPoint > &	segment,
		QgsPoint &	intersection
	)

static

performs the intersection of a circle and a line

Note: from the two solutions, the intersection will be set to the closest point

Definition at line 39 of file qgsadvanceddigitizingdockwidget.cpp.

◆ penultimatePoint()

QgsPoint QgsAdvancedDigitizingDockWidget::penultimatePoint ( bool * exists = nullptr ) const

The penultimate point.

Helper for the CAD point list. The CAD point list is the list of points currently digitized. It contains both "normal" points and intermediate points (construction mode).

Definition at line 1332 of file qgsadvanceddigitizingdockwidget.cpp.

◆ pointChanged

void QgsAdvancedDigitizingDockWidget::pointChanged ( const QgsPoint & point )
