A Simple Discrete-Event Simulation: Part 89
Direct link for mobile devices. I was walking a few miles in the nice weather this evening when two possible solutions popped into my head for the DisplayGroup drag problem I had in the simulation app (where the pointer arrow … Continue reading

A Simple Discrete-Event Simulation: Part 88
Direct link for mobile devices. Today I updated the code to define DisplayGroups for all non-Path components, which means the internal data for each component will become visible when the relevant component is clicked. Moreover, each visible DisplayGroup object can … Continue reading

A Simple Discrete-Event Simulation: Part 86
I was working to add the next behavior when I discovered that things that used to work no longer did. After a bit of digging I realized that the problem was trying to handle click events separately from mouseup and … Continue reading

A Simple Discrete-Event Simulation: Part 85
Direct link for mobile devices. Today I made the selection action work using touch events in addition to the mouse click event. The touch mechanism in JavaScript for mobile browsers does not current have a click counterpart so we have … Continue reading

A Simple Discrete-Event Simulation: Part 84
Today I implemented the ability to select graphic elements using a mouse click. This involves sensing the mouse click event and its location, variations of which we’ve already visited, and identifying the graphic element on that part of the screen. … Continue reading

A Simple Discrete-Event Simulation: Part 82
Today I added the ability to use the mouse to drag the 2D display around within its canvas. I had to update the various pan functions to allow specification of an arbitrary distance increment, though there are a number of … Continue reading
