Currently I am getting issue when the user selects a detailed node from the node (as shown below screenshot(Highlighted color is “yellow”), and then when another detailed node is selected, the highlight of the previously selected detailed node remained same.
You can check my below screenshot in which previously selected node is not getting reset.
You talked about the user changing the selection, perhaps by clicking on another node, or by clicking in the background of the diagram to clear the selection. Both of those cases cause the “ChangedSelection” DiagramEvent to be raised. I think there are lots of examples of such a listener in the various samples. You’ll want your listener to update the highlighted state (i.e. background) of some of the items in some of the nodes.
I tried to find the solution which you suggested using this event “ChangedSelection” DiagramEvent listener.
But this “ChangeSelection” method will only work on the Parent node. I did R&D i found this URL in which they mentioned about the “selectionChange” event but it will only work on Main node. You can check below URL GoJS Events -- Northwoods Software
But if you check my requirement its working fine on parent node or Main node as per your example but its not working fine on child node or subNode .Please check my below screenshot.
Please share with me any example in which selection is working on subChild Node as well.
I still do not understand your requirements, which is why I described some mechanisms by which you could implement the exact policies that only you understand at this time.
Are you saying that at most one Node can have any highlighted items (Panels within a Node) at any instant? But that a Node may have any number of items highlighted at the same time?
If that description is incorrect or incomplete, please describe the rules much more precisely, showing both valid and invalid configurations in separate screenshots. And because you seem to have some sequences of state that you want, show both before and after screenshots.
My Expectation here :- Whenever user will select next node then previous node get should be reset(Highlighted color should be reset in default color) or should be in default state.
But currently if user will click on any node(child node or sub node) than all the previous node is in selected mode means(in yellow color) and i want to reset the color in default state.
Parent Node :- Below whole diagram is Parent node i am considering and on this node ChangedSelection ” DiagramEvent listener is working fine at a time only node we can select and whenever user will select new node then previous color or node is getting reset that means in this case its working fine.
Child Node or Sub Node:-
I have attached the sub node, in this sub-child node i am unable to reset the previous state.
Means whenever user will select new subchild node or new sub node then previous yellow color is not getting reset.
MY Expectation is :–
I just want to reset their background (yellow color) if user will select next new node then i want to reset the previously highlighted background color(yellow color)
Can you guide me how I can stop onClick event on node. I want to implement the graph only in read or view mode, i don’t want to add click event on node. Can you share with me code or help me out
In gojs we have one inbuilt features for selection the node which is maxSelectionCount.
I have added the maxSelectionCount = 1 because i have use this property because of default node selection .
I did’t add any click event handler but still because of this gojs graph property maxSelectionCount =1 i am able to click on any node .
Can you guide me here i don’t want to remove this property maxSelectionCount because i need default selection , but i want to stop onClick event please guide me how i can do that
