Member Function Documentation

def layertree.LayerTree.AddLayer	(	self,
		ltype,
		lname = `None`,
		lchecked = `None`,
		lopacity = `1.0`,
		lcmd = `None`,
		lgroup = `None`,
		lvdigit = `None`,
		lnviz = `None`,
		multiple = `True`
	)

Add new item to the layer tree, create corresponding MapLayer instance.

Launch property dialog if needed (raster, vector, etc.)

Parameters:

ltype	layer type (raster, vector, 3d-raster, ...)
lname	layer name
lchecked	if True layer is checked
lopacity	layer opacity level
lcmd	command (given as a list)
lgroup	index of group item (-1 for root) or None
lvdigit	vector digitizer settings (eg. geometry attributes)
lnviz	layer Nviz properties
multiple	True to allow multiple map layers in layer tree
