Toolbar
- Pointer
The pointer allows user to select single objects and drag across the diagram. It can be enabled by pressing "1" on the keyboard.
- Box selection
The box selection tool allows user to select multiple objects simultaneously. By doing this you can delete multiple objects at the same time or or change the colour of multiple objects by selecting them and opening the options panel giving them a chosen colour from the color palette .
- Entities
By long-pressing this the user can chose between placing an ER-entity, UML class, IE entity or State diagram state into the diagram.
ER entity
By using this button you can create new objects.
- Relation/Inheritance
Allows user to place ER-relations, UML-inheritence and IE-inheritance in the diagram by long pressing the button.
ER Relation
Create a relations between different objects.
- ER Attribute
Create a attribute that you can combine with an object. Example named: firstname, lastname, adress.

Description
The functionality of different types of diagrams needs to be documented. A wiki page need to be created with the current functionality and some technical description of how it is achieved. There should also be references to closed issues that have implemented said functionality. There should be clear descriptions for each new topic with pictures if user interface is described. File paths and code blocks should be included when describing code implementation. An example of good structure can be found in: https://github.com/HGustavs/LenaSYS/wiki/Diagram-dugga-overview
Job
Create a new wiki page describing how the ER-diagrams currently work.
