functional implementation for Redline/StickyNotes

cvjs_graphicalObjectOnChange() is a callback Method on Creation, Delete and Change. It captures any action on Redline and StickyNote objects:

The cvjs_graphicalObjectOnChange(type, graphicalObject, id, evt) callback contains the parameters:

  • type: The types of interaction are: Create, Delete, Click, Move, Resize, Scale, Edit …

  • graphicalObject: The grapical object itself, there are different types of redlines and space objects

  • id: The ID of the object. Note that the corresponding node of the object will typically be RED_xxx for Redlines , SNOTE_xxx for StickyNotes and NODE_xxx for Space Objects

  • evt: The event used with click operations, null if no mouse event or irrelevant for callback operation.

For setting up Redlines see: Redlines

Redlines and SticyNote shares a common javascript structure in CADViewer v6. For CADViewer v7, the data-structure of Redlines and StickyNotes have been updated to a JSON based structure similar to Space Objects, see the Redline Formats.

CADViewer 6

For CADViewer 6, Application programmers have two main API methods to use to extract and add redlines/stickynotes to the canvas based on interaction.

CADViewer 7

For CADViewer 7, there are 6 new methods extract and add redlines/stickynotes to the canvas based on interaction, all are JSON based and can be freely used with any Front-End Framework.

Below are typical implementations of cvjs_graphicalObjectOnChange() for Redlines and StickyNotes:

}

if (type == 'Click'){
    // remove this entry from my DB

}
}

// Addding the Redline and StickyNote object back into the drawing
cvjs_setStickyNotesRedline(myredline);  // cadviewer 6
cvjs_setAllRedlineStickyNoteObjects(myredlinestickynoteObjects)   // cadviewer 7
