- Description
- Prompt for segment selection, get a list of band indices.
- V1 Function Name
- New to V2
dialog.SelectBands prompts the user to select bands, and returns a list containing the indices of the selected bands. It's the equivalent of a user pick for the bands ingredient in a GUI recipe.
dialog.SelectSegments is part of the dialog namespace, but it's separate from the other functions. It does not require or work with dialog.CreateDialog or dialog.Show.
Example[]
The Lua code:
bands = dialog.SelectBands ()
print ( #bands .. " bands selected" )
bndlst = ""
for ii = 1, #bands do
bndlst = bndlst .. bands [ ii ]
if ii < #bands then
bndlst = bndlst .. ","
end
end
print ( "bands = \"" .. bndlst .. "\"" )
might produce the output:
5 bands selected bands = "1,21,22,27,29"
