QGIS独自のCursorの使用方法

Posted at

はじめに

QgsMapToolのCursorを情報参照表示などで使われているカーソルに変更したかったための備忘録

カーソル定義

カーソルはQgsApplicationクラスのCursorで7個定義されています。

ZoomIn Zoom in.
ZoomOut Zoom out.
Identify Identify: obtain information about the object.
CrossHair Precisely identify a point on the canvas.
CapturePoint Select and capture a point or a feature.
Select Select a rectangle.
Sampler Color/Value picker.

取得方法

カーソルの定義からのQCursorの取得もQgsApplicationクラスのgetThemeCursorを使うことで取得できます。

cursor = QgsApplication.getThemeCursor(QgsApplication.Identify)

例: MapToolのCursorを変更する

tool = QgsMapToolIdentifyFeature(iface.mapCanvas())
cursor = QgsApplication.getThemeCursor(QgsApplication.Identify)
tool.setCursor(cursor)
