I was trying to make a tutorial for the Linkage software to show how to design a vertical sliding garage door. The door is built out of four or five segments with rollers at the intersections. The rollers roll in tracks that are vertical then transition through a…
Continue reading“Code” or “source code” are terms used to describe the written words in a programming language that have meaning in the context of that language. What I’m writing here right now is not “code” even though to someone who only reads and speaks Latin or Greek, it would…
Continue readingThe image above shows the current state of the Linkage app for the Mac. There is a main editor window and a sidebar with two panels. The visible panel is the “properties” panel. The other panel is the element selection panel where elements can be selected and deselected…
Continue readingI decided, after talking to my dad about neural networks, to write a creature simulator that allows creatures to evolve. This is a complicated type of software for me to write because I want to make it totally flexible and yet get it done and working. There are…
Continue readingI read a while back about how linked lists were not included in the standard Swift library because they are something that only gets used in classroom situations where people are learning about algorithms., or some such nonsense (in my humble opinion). But then I did a test…
Continue readingI’m working on the Mac version of the Linkage app and I’ve been having some trouble with panning and zooming. When a single finger is slide along the top of the Apple Magic Mouse, the software gets a “scrollWheel” event. It’s a Magic Mouse so there are values…
Continue readingThe documentation says something to the effect of “onMeasure() is called to determine the size of the view.” and “onLayout() is called to set the size and position of the child views.” The problem is that onMeasure() is called before onLayput() and never after it. How can a…

Continue readingI had some C++ code that would determine if any element in a list was selected. A “selected” element is one that has a boolean variable “isSelected” set to be true: bool bLinkSelected = false; POSITION Position = pConnector->GetLinkList()->GetHeadPosition(); while( Position != 0 ) { CLink* pLink =…
Continue readingA Linkage document file contains coordinates based on there being 96.0 pixels per inch. If the software is rendering onto an old monitor then the document units are scaled based on the amount of zoom in effect and then they are translated to different coordinates if the document…
