When adding a new feature (polygon) I would like to close form when centroid
does not intersect a polygon from an other layer
Here is my full python init form dialog function:
# -*- coding: utf8 -*-
from qgis.core import QgsVectorLayer, QgsFeatureRequest, QgsRectangle,
QgsGeometry, QgsProject, QgsPointXY
import qgis.utils
from PyQt5.QtWidgets import QDialogButtonBox, QLineEdit, QComboBox
from PyQt5.QtCore import QObject
import os.path
import getpass
def dealWithPoly(dialog, layerid, featureid):
global editMode
global iface
iface = qgis.utils.iface
geom = featureid.geometry()
if geom:
editMode = 'insert'
layers = QgsProject.instance().mapLayers().values()
canvas = iface.mapCanvas()
geo_point = geom.centroid()
canvas_crs_txt = canvas.mapSettings().destinationCrs().authid()
canvas_crs = canvas_crs_txt.split(':')[1]
layerNameRPG = 'MAEC2023 parcelles'
testlayerRPG = QgsProject().instance().mapLayersByName(layerNameRPG)
if testlayerRPG:
bv = testlayerRPG[0]
layer_crs_txt = bv.crs().authid()
layer_crs = layer_crs_txt.split(':')[1]
if canvas_crs != layer_crs:
xform =
QgsCoordinateTransform(QgsCoordinateReferenceSystem('EPSG:'+canvas_crs),
QgsCoordinateReferenceSystem('EPSG:'+layer_crs), QgsProject.instance())
geo_point.transform(xform)
find_parcelle = False
polygon = [feature for feature in bv.getFeatures()]
for pol in polygon:
geo_pol = pol.geometry()
if geo_pol.contains(geo_point):
pacageVal = pol['Pacage']
numIlot = str(pol['Num_ilot'])
find_parcelle = True
break
if not find_parcelle:
txt = u"Saisie en dehors des limites du RPG"
iface.messageBar().pushMessage(txt, level=Qgis.Warning)
#dialog.parent().reject()
dialog.close()
#print(dialog.parent())
else:
linedit_pacage = dialog.findChild(QLineEdit,"PACAGE")
linedit_pacage.setText(pacageVal)
linedit_numilot = dialog.findChild(QLineEdit,"NUM_ILOT")
linedit_numilot.setText(numIlot)

Can you provide a little more code?
And more info where exactly it is called (in the startup.py or in some form
init code?
Is 'dialog' available in the code part in which you try to close it?
Regards,
Richard Duivenvoorde
