Description Ralf Habacker 2016-12-04 13:11:43 UTC
According to http://www.uml-diagrams.org/component-diagrams.html component ports are aligned to the outline border of the related component eg.  -----[]-----. 

With recent umbrello versions the ports are displayed outside of the component  e.g _____[]____. This should be fixed.

How to reproduce:
1. Start umbrello
2. Create a new component diagram
3. Add a component
4. Add a port to the component created at 3.

What happens:
The port displayed at the top outline of the component is not vertical aligned 

What is expected:
The port at the top outline of the component should be aligned vertical

> Place Pin/Ports onto parent border.

Just to be sure: Your patch limits this behavior to ports only as indicated by the title ?  https://de.wikipedia.org/wiki/Pin_(UML) mentions that pins need to be displayed still outside. I guess the class PinPortBase needs to have a protected member to be able to switch on this new behavior only in the derived PortWidget constructor.

The patch changes PinPortBase, so affects both Components and Activities.
I wasn't aware that they need to be handled differently. I'll rework the patch.

Pins stay attached to outside shape.

Place ports onto parent border

Works as expected

Below are some notes relating to code style: 


+#ifndef CHILDWIDGETPLACEMENT_H__

please remove the traling '__

+class ChildWidgetPlacement

can you add some docs to the class and 

+#define CHILDWIDGETPLACEMENTPIN_H__

dito 


+#include <umlwidgets/childwidgetplacement.h>

either 
#include "umlwidgets/childwidgetplacement.h"
or 
#include "childwidgetplacement.h"


+#include <umlwidgets/umlwidget.h>

use "" instead of <> because the related headers are local

Fix placement of Port when resizing parent.

When Port is placed on Upper-Right or Lower-Left corner of parent,
it is now moved correctly when the parent is resized.

Indeed - I forgot to rebuild after refactoring. Patch updated.

These patches also introduced a previously non-existent problem: The created ports are not located at the cursor position when clicking on the component, but always in the upper left corner.

Cannot reproduce this problem with current git master.
The new port is created near the mouse release location, i.e. usually inside the component.
After dragging the port to a component edge, it stays in place and moves in sync with the component.

This was fixed on addressing bug 403692.
