QgsAdvancedDigitizingDockWidget::CadConstraint class

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

It contains all values (locked, value, relative) and pointers to corresponding widgets.

Public types

CadConstraint(QLineEdit* lineEdit, QToolButton* lockerButton, QToolButton* relativeButton = nullptr, QToolButton* repeatingLockButton = nullptr): Constructor for CadConstraint.

auto isLocked() const -> bool: Is any kind of lock mode enabled.
auto isRepeatingLock() const -> bool: Returns true if a repeating lock is set for the constraint.
auto lineEdit() const -> QLineEdit*: The line edit that manages the value of the constraint.
auto lockMode() const -> LockMode: The current lock mode of this constraint.
auto relative() const -> bool: Is the constraint in relative mode.
void setLockMode(LockMode mode): Set the lock mode.
void setRelative(bool relative): Set if the constraint should be treated relative.
void setRepeatingLock(bool repeating): Sets whether a repeating lock is set for the constraint.
void setValue(double value, bool updateWidget = true): Set the value of the constraint.
void toggleLocked(): Toggle lock mode.
void toggleRelative(): Toggle relative mode.
auto value() const -> double: The value of the constraint.

Constructor for CadConstraint.

Parameters
lineEdit	associated line edit for constraint value
lockerButton	associated button for locking constraint
relativeButton	optional button for toggling relative constraint mode
repeatingLockButton	optional button for toggling repeating lock mode

Returns true if a repeating lock is set for the constraint.

Repeating locks are not automatically cleared after a new point is added.

The current lock mode of this constraint.

Returns	Lock mode

Sets whether a repeating lock is set for the constraint.

Parameters
repeating	set to true to set the lock to repeat automatically

Repeating locks are not automatically cleared after a new point is added.

Set the value of the constraint.

Parameters
value	new value for constraint
updateWidget	set to false to prevent automatically updating the associated widget's value
