On Interface and Software Design

First, designing a user interface has almost nothing to do with writing software. There are software limitations that affect the design but other than that, the underlying code and data structures should not be considered until after the user interface is fully designed. I ran into this issue…

Who writes code like this?

This is some Microsoft code in an example program: CMFCRibbonColorButton* pBtn1 = new CMFCRibbonColorButton(ID_RIBBON_CBTN_1, _T(“&Simple”), TRUE, 0, 0); pBtn1->SetAlwaysLargeImage(); pBtn1->SetDefaultCommand(FALSE); pPanel1->Add(pBtn1); CMFCRibbonColorButton* pBtn2 = new CMFCRibbonColorButton(ID_RIBBON_CBTN_2, _T(“Simple with Options”), TRUE, 1, 1); pBtn2->SetAlwaysLargeImage(); pBtn2->SetDefaultCommand(FALSE); pBtn2->EnableAutomaticButton(_T(“&Automatic”), RGB(0, 0, 0)); pBtn2->EnableOtherButton(_T(“&More Colors…”), _T(“More Colors”)); pPanel1->Add(pBtn2); CMFCRibbonColorButton* pBtn3 = new CMFCRibbonColorButton(ID_RIBBON_CBTN_3,…

Ribbon Bar Working in Linkage 2.0

I now have the linkage program working with the new ribbon bar. I’m not sure if it’s much better than the old-style toolbar but it’s prettier. I wanted to use an image gallery in the ribbon bar to select sample mechanisms but even with 128×128 pixel images, it’s…

Solid Links and Thick Lines

I am still stumped on how to simulate the link/slider/slider mechanism I described in an earlier post. I think that there is just no way to do this with math since the curve I need to intersect can only be described with an equation that includes a time…

Another Special Case!

And another and another. I found another case that requires special code to deal with the geometry that is different from all other cases. the thing to notice in this situation is the fact that connector C controls the location of link 1 horizontally in this case but…

More Special Cases

I was back at work last night writing code to handle special cases in the linkage simulator. It turns out that every type of connection is a special case, almost. Here is what I have working: There is one case I can see that is missing but the…
