clear geometry picker

GIS Support

is it possible to mimic the X button on the geometry picker?

I can clear the geometry with Clear Collection activity on =$formQueryOptions.state.geometryMapSelection.value.geometry

but the old shape still exists and flashes on the screen the next time the user draws a box, the old shape still flashes

I've also tried to Clear Graphics on the graphicsLayerX_layer' that they use

essentially there is no need to show the graphic on the screen, I want to return the user to the default state and reset the geom picker

    Did you figure this out already? If not, you can use a Run Command activity and clear the graphics that way. This is what I had to do in order for a graphic they defined a feature with not to show up in the Print product. 

    Command Name: 

    map.clear-markup

    Thanks for the suggestion, much appreciated. I should have noted that I'm targeting Web AppBuilder so that's not available to me.

    My users haven't noticed the original graphic that still persists so for now its just a me issue.

    I just got this working on my end, so posting a solution for others (since this showed up on Google early for me). Hope it helps, even if late.

    For your answer in short: You also need to delete the appropriate `state` array value you want to get rid of the map objects. Likely at:
    `$formQueryOptions.state.geometryMapSelection.state`
    (the indexes should match the geometry you are deleting)


    For a ton of info to potentially help others:

    My use case, this can be done by setting properties of your original Geometry Picker [object]. Namely the Geometry Picker [object]'s properties `state` (array values) and `value.geometry` (array values).

    You can remove the relative indexes from both of these arrays to mimic the deletion of a Geometry Picker item. The use case I've needed several times involves logic that determines if the drawn object is good or not. I normally want to automatically delete this drawing instead of depending on the user understanding they need to do it. For me this is always the most recently drawn object (or the last indexes), but the same principle can be applied to delete whichever points you want.

    Below is an example of the values you care about. In this console I have 3 points. (the `state` array has a fourth value that is used for the next point to be drawn from my understanding):

    Unfortunately, I don't have any sandbox I can share VertiGIS tools/components/logic with. I have a .json file that has some of the basic logic I use to grab the above values, delete the last drawn point values, then reapply to the original Geometry object effectively deleting the unwanted drawn points automatically. It has notes that hopefully help explain what it is doing. Since I can't upload or share logic I have the .json code in the below block:

    Here's what it looks like in VertiGIS:


    Either way, hope you got a good solution and/or that this helps others!
