BSA – Next Steps

BSA is a huge task so it is important to keep focus to get something that we can start using soon even on beta level. I have done most of links which is the more complex part of the drawing engine. What is remaining is manual link movements. In this first version I will only…

BSA – Merging HMI into PLD

This is PLD where I use HMI Form as building blocks. I am not sure about this idea, but a HMI screen is a complex object with multiple paths and PLD can actually visualize this. in this example I show what other HMI forms are called, but it could as well have been the menu…

BSA – Automated Lines

This test diagram shows some of the automated lines used in BSA. As you draw diagrams you also need to use line (or links) between the symbols to create a diagram. But it is important to remember that we are NOT making drawings, we are creating a specification where the lines are translated to source…

BSA – UML State Diagram

I got the first link designs connecting symbols working. I will not use much time on State Diagrams in first round as my objective is still to create GUI designer first. But, working on advanced, embedded solutions every day I am actually looking forward to be working with BSA once it becomes fully functional. The…

In this case I have drawn 3 rectangles and have the selectors as part of the rectangle drawing using a different ZIndex.  Sadly the ZIndex only work on the locat drawing, so as the middle is selected it’s selectors are…

BSA – DataSource

This is an updated drawing of the DataSource concept in BSA. The idea is that easyIPC provide an uniform access method so that the HMI user don’t need to concern himself with how data arrives or are sent. easyIPC have it’s own native transport protocol and network, but must be able to interface to other…

BSA – GPU vs Raster graphics

The drawing above show the classic Raster Graphics where the drawing is done directly on the screen by a CPU. This is how classic Qt and C#/Forms works. The drawing below show the same with WPF/QML involved. The code (or QML/XAML) will in this case create and object that we can manipulate from code, but…

BSA – WPF Line Moving

The diagram above show an actual PolyLine on a diagram – or more correctly two lines. Drawing shapes you get automatic hit test support as the mouse moves over the line, so only a few commands was needed to implement a Line Move feature. The chellenge was more that a line with thickness 1 was…

BSA – Dark vs Light

This first picture show the Dark Theme version made with QML, while the second show the Light Theme version made with WPF. The Light images are not all there yet, so I need to work on those. I am getting there with the light version as well. I decided to ditch TreeView and make a…
