示例1: QDialog
# 需要導入模塊: from qgis.gui import QgsMapLayerComboBox [as 別名]
# 或者: from qgis.gui.QgsMapLayerComboBox import setCurrentIndex [as 別名]
# coding: utf-8
from PyQt4.QtGui import QDialog, QFormLayout
from qgis.gui import QgsFieldComboBox, QgsMapLayerComboBox
# Create dialog
new_dialog = QDialog()
# Add combobox for layer and field
map_layer_combo_box = QgsMapLayerComboBox()
map_layer_combo_box.setCurrentIndex(-1)
field_combo_box = QgsFieldComboBox()
# Create a form layout and add the two combobox
layout = QFormLayout()
layout.addWidget(map_layer_combo_box)
layout.addWidget(field_combo_box)
# Add signal event
map_layer_combo_box.layerChanged.connect(field_combo_box.setLayer) # setLayer is a native slot function
def on_field_changed(fieldName):
print(fieldName)
print("Layer field changed")
field_combo_box.fieldChanged.connect(on_field_changed)
new_dialog.setLayout(layout)
new_dialog.show() # To see possibility of this component, you need at least a layer opened
