User drawn rectangle doesn't persist on map after mouse-up

TyroneLigon1 — Fri, 03 May 2024 20:16:10 GMT

I apologize in advance - the code is running on an intranet, and I can't copy/paste.

I have a dockpane with a button mapped to a rectangle tool. The user uses the tool to drag a rectangle on the map. When the user completes the rectangle via mouse-up, the rectangle disappears from the map.

Do I need to create a graphic from the geometry created by the tool and add it to the map's graphic layer?

In my map rectangle tool class, I initialize with:

IsSketchTool = true;
CompleteSketchOnMouseUp = true;
SketchType = SketchGeometryType.Rectangle;
sketchOutputMode = SketchOutputMode.Map;

The rectangle extent parameters are then used to open a web page via another button on the dockpane.

Thanks!

EDIT: lol - well, after just finishing writing this reply it struck me that maybe it is _not_ the "show selection graphic behavior" that you are after! Somewhat presumptive on my part, apologies - that said, just in case, and/or if someone else _is_ (who reads this post) I will leave my reply...and we will still add this to the SelectionEnvironment at 3.4.

it looks like this was never exposed in the selection environment public api - https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/topic14140.html

What you are looking for is the equivalent to the "Display the interactive selection graphic" checkbox on the Application selection settings UI.

I will pass this on to the dev team for 3.4.

In the meanwhile, this will work (but requires use of an internal namespace) - maybe do this in the tool activate and set it back to the previous setting when your tool is deactivated - your call.

//fyi using ArcGIS.Desktop.Internal.Mapping; ... internal class MySelectionTool : .... { ... public void SetShowInteractiveSelectionGraphic(bool showGraphic) { var map_module_internal = FrameworkApplication.FindModule("esri_mapping") as IInternalMappingModule; //Must be called on the QueuedTask! or will throw //CalledOnWrongThreadException map_module_internal.SelectionSettings. SetShowInteractiveSelectionGraphic(showGraphic); } public bool GetShowInteractiveSelectionGraphic() { var map_module_internal = FrameworkApplication.FindModule("esri_mapping") as IInternalMappingModule; //should be fine being called from the UI thread return map_module_internal.SelectionSettings. ShowInteractiveSelectionGraphic; } ... //usage internal bool _keepShowSelectionGraphicSetting = false; //somewhere - perhaps tool activation QueuedTask.Run(() => { _keepShowSelectionGraphicSetting = this.GetShowInteractiveSelectionGraphic(); if (!_keepShowSelectionGraphicSetting) this.SetShowInteractiveSelectionGraphic(true); ... }); //somewhere - perhaps tool deactivation QueuedTask.Run(() => { if (_keepShowSelectionGraphicSetting != this.GetShowInteractiveSelectionGraphic()) this.SetShowInteractiveSelectionGraphic( _keepShowSelectionGraphicSetting); ... });

I am getting the result I was expecting - the user drags a rectangle on the map, and the rectangle remains after the user finishes the drag operation. I now have to extract the rectangle's extent, and provide an option to remove the rectangle from the map, which I will address in another post. Thanks!

Tyrone, I stand corrected - i did a bit of digging and this is in the public api:

https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/topic14160.html

https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/topic14152.html

So, u shld be able to do SelectionEnvironment.SetShowSelectionGraphic(true | false). SelectionEnvironment.ShowSelectionGraphic will give u the current "show graphic" value. "SetShowSelectionGraphic" must be called on the MCT via QueuedTask.Run.

SelectionEnvironment is a static class within ArcGIS.Desktop.Mapping
