I want to allow drawing a rectangle on top of rectangle in the following example. Currently if the checkbox is checked and while dragging on top of rectangle it starts moving it, I want to allow drawing on top of it.
Notice in the Drag Creating sample, Drag Creating Tool, the installation of the DragCreatingTool is done by modifying the ToolManager.mouseMoveTools list:
myDiagram.toolManager.mouseMoveTools.insertAt(2, . . .);
Putting it at index 2 means that it comes after the LinkingTool and the DraggingTool in the ToolManager.mouseMoveTools list: ToolManager | GoJS API
In other words, that way the DragCreatingTool has lower priority than those two tools.
But you can easily have the DragCreatingTool have a higher priority than the DraggingTool by inserting it before the DraggingTool:
myDiagram.toolManager.mouseMoveTools.insertAt(1, . . .);
That was quick! thanks a lot, working as expected :D
It’s about as easy as it gets.
