Elements will automatically be created at appropriate
positions when context menu create entries are being
clicked (rather than dragged).
This marks a major step forward for mobile modeling,
too as dragging, especially dragging out from very small
controls is very cumbersome to do.
Things we take into account:
* for bpmn:FlowNodes, we try to compute the current
distance between elements on the flow based on
connections going in and out of the flow nodes
source element
* for bpmn:TextAnnotation we assume placement of the
element top right of the source shape
* for bpmn:DataObject and friends we assume a
placement bottom right of the source shape
* for all elements, we try not to place elements on
top of each other; i.e. new elements will be pushed
up or down accordingly, if an element at a chosen
position does already exist
Integration into other services:
* context pad provider works with autoPlace, if
available and defaults to drag start without
* auto placed elements are selected and direct editing
may conditionally be activated based on element type
(LabelEditingProvider knows the rules)
Users can out out of autoPlace by specifying the configuration
property `config.contextPad.autoPlace = false`.
Closes#563
BREAKING CHANGE:
* This breaks the default interaction from the context
pad; if you rely on clicking to start the drag
you can opt out of autoPlace:
```
new BpmnJS({ contextPad: { autoPlace: false } });
```
You are now able to morph between collapsed and expanded pools
* Not possible to drop elements in a collapsed pool
* if a expanded pool collapses, the children are deleted
Closes#365
This commit makes use of the provider concept introduced
in diagram-js. The replace menu entries are now created
in the replace menu provider. This separates BpmnReplace
from the entry creation in the popup menu.
Closes#428
Lanes are going to be modeled via the parents context-pad only.
This commit
* removes lanes from the palette
* adds lane actions to the context-pad
Related to #379
This simplifies the ways we work with replacements.
Instead of monkey-patching the original replace functionality we
* create the business object / target object
* pass it to replace
A simple way that works well with our existing infrastructure.
Other changes:
* fixes redo / undo issues.
* splits context-pad + replace
Closes#180
