From: Billy Patton on 28 Feb 2007 09:50 First forgive the ramblings. Second I have a 2 hour commute on a train daily and this is my train project. My original project was done in wxxt-1.67 Quite a few years ago. The project it a layout editor. Original was a proprietary ascii format in a lisp style. tons of () Since this database can have N rect, closed polygons, circles, donuts, center line figures, center point rectangles, text and text attached to any of the previously named preceeding I chose to do and API to the data. The API only passed back text, polygons and rect. Since there can be millions of these figure types, I chose to draw into a bitmap, then blit to the screeen. One call to x-server not millions. I also chose to stay away from letting each sumbol be it's own object, figuring that millions of object would just slow down the whole procress. The original was done on a TI 35mgh notebook running slackware. In doing this I maintained scale factors of the data,. shiftX and shiftY to "move" the data around the bitmap. Since the canvas 0,0 is at the upper left I had to convert all drawings so that it mirrored the data in the Y direction. I did this via 2 functions G2W -> Graphics to World W2G -> World to Graphics Every xy coord went through these. They accounted for scale, shift and canvas size. Even mouse movement went through these. I'm now trying to adapt most of my functionality to wxWidgets and the methods of callback Questions I need to answer. 1. Is the SetUserScale better than handling it my self? If I use I would have to use GetUserScale to adjust the points for selecting data in the database. 2. Is there a way to relocate 0,0 on a canvas? 3. I would like to put a much better API between teh graphics and the data. I would like to use gdsii,LAFF,Oasis,OpenAccess and mebes, eventually. Anyone have a concept for how to do this? I've looked through the samples and the contrib/samples to get ides of how to do get the canvas's and the onPaint functioning. I don't believe I can eliminate the G2W or W2G Here's a sample of what scale would have to look at (ATTR 'UNITS'( (TEXT '0.00100 MICRONS'))) (ATTR 'MINGRID'( (TEXT '0.00100 0.00100'))) I've pulled down fl.pdf, gizmos.pdf, mmedai.pdf, ogl.pdf,svg.pdf, tes2rtf.pdf and wx.pdf. These are excellent references, althoug I only use wx.pdf. I've done the tutorial. I have no problem with the frames, menus in the frames and the callback stuff. I've created the canvas, the bitmap within and the DC. I understand the flow and why I did what I did 10 years ago, but am looking for something a little easier and less confusing. Hoping the wxWidgets have solved some of these problems.

From: Billy Patton on 1 Mar 2007 06:59 Thanks, I'll take a close look at wxArt2D Klaas Holwerda <db348(a)nl.thalesgroup.com> wrote: Billy Patton wrote: > I'm now trying to adapt most of my functionality to wxWidgets and the > methods of callback So yopu should first go to wxArt2D, which has all you want, and more.
