To use the transform function, pass True as the 2nd argument to the constructor of the PrintSnappedPoint class constructor.
#PMOUSE X PMOUSE Y CODE#
However, I would recommend changing the epsg code of the destination crs to an accurate local projected crs such as a UTM zone appropriate to your area. If yes, when we drag and drop.4 answers Top answer: Hi Nam,We suggest you to diagram’s Magnification to find our scale value once. Angle Math.Atan2(x,y) For example: You could have a variable for you current turrent position (middle point of it) Point Turret new Point( 10, 10) Than you could calculate the angel as follows in a mouse handle function: Angle Math.Atan2(Mouse.X - Turret.X, Mouse.Y - Turret. In this example my project crs is epsg:4326 so I transform the point from that to epsg:3857. Could you please confirm us whether you want nodes position after drag and dropped the nodes in the diagram. I have updated the code above to give an example of using QgsCoordinateTransform class to transform the the snapped click-point from the project crs to another crs of your choosing. #to transform snapped click-points, pass True as 2nd argument to constructor PopUP window new PopUp () window.Location .Position window.showDialog () even tried the window.Location MousePosition but the pop-up window appears. Self.s = QgsSnappingConfig.IndividualLayerSettings(False, QgsSnappingConfig.NoSnapFlag, 25.00, The desired result is, the win form (pop-up window) should show right beside or on the location of the mouse cursor on the screen by clicking a linklabelcontrol. pmouseX represents the previous x-coordinate. I used hard coded X and Y along with Insert Mouse Click and Insert Mouse Move. Global variables represents the coordinates of the previous mouse position. Print('Point snapped to vertex: '.format(point)) basically I am trying to drag and drop a row in HTML table to another position. Self.x_form = QgsCoordinateTransform(self.src_crs, self.dst_crs, self.project) Self.dst_crs = QgsCoordinateReferenceSystem('EPSG:3857') #Best to change epsg code below to a local projected crs (e.g. #Define source and destination crs's and instantiate QgsCoordinateTransform class Self.c.setIndividualLayerSettings(self.l, self.s) Self.s = QgsSnappingConfig.IndividualLayerSettings(True, QgsSnappingConfig.VertexFlag, 25.00, Self.c.setMode(QgsSnappingConfig.AdvancedConfiguration)
QgsMapToolEmitPoint._init_(self, self.canvas) class PrintSnappedPoint(QgsMapToolEmitPoint):ĭef _init_(self, canvas, transform=False): Called when a mouse event has been received. Paste into a new editor in the Python console, select an active layer (must be a vector layer, since there is no safeguard in the script to handle raster layers etc!) and click run to test. The mouse cursors current x position on screen in content coordinates.
