Detailed Description

Abstract class that can be derived to implement advanced editing on mesh.

To apply the advanced editing, a pointer to an instance of a derived class is passed in the method QgsMeshEditor::advancedEdit().

Since

QGIS 3.22

Member Function Documentation

apply()

virtual QgsTopologicalMesh::Changes QgsMeshAdvancedEditing::apply ( QgsMeshEditor *  meshEditor )

protectedpure virtual

Apply a change to mesh Editor.

This method is called by the QgsMeshEditor to apply the editing on the topological mesh

The method has to be implemented in the derived class to provide the changes of the advanced editing

clear()

void QgsMeshAdvancedEditing::clear

(

)

Removes all data provided to the editing or created by the editing.

Definition at line 46 of file qgsmeshadvancedediting.cpp.

isFinished()

bool QgsMeshAdvancedEditing::isFinished ( ) const

virtual

Returns whether the advanced edit is finished, if not, this edit has to be applied again with QgsMeshEditor::advancedEdit() until is finished returns true.

Reimplemented in QgsMeshEditForceByPolylines.

Definition at line 55 of file qgsmeshadvancedediting.cpp.

message()

QString QgsMeshAdvancedEditing::message

(

)

const

Returns a message that can be provided by the advanced editing when applying is done.

Definition at line 41 of file qgsmeshadvancedediting.cpp.

setInputFaces()

void QgsMeshAdvancedEditing::setInputFaces

(

const QList< int >

faceIndexes

)

Sets the input faces indexes that will be used for the editing.

Definition at line 36 of file qgsmeshadvancedediting.cpp.

setInputVertices()

void QgsMeshAdvancedEditing::setInputVertices

(

const QList< int >

verticesIndexes

)

Sets the input vertices indexes that will be used for the editing.

Definition at line 31 of file qgsmeshadvancedediting.cpp.

text()

QString QgsMeshAdvancedEditing::text ( ) const

virtual

Returns a short text string describing what this advanced edit does. Default implementation return a void string.

Reimplemented in QgsMeshEditingDelaunayTriangulation, QgsMeshEditRefineFaces, QgsMeshTransformVerticesByExpression, and QgsMeshEditForceByPolylines.
