gerhardhziegler Posted June 24, 2017 Share Posted June 24, 2017 Hi, are there any good solutions including examples for using a canvas or any kind of alternative for taking signatures in mobile?Using TUniCanvas in a mobile forms answers with "Ext.Form.Canvas is not a constructor", I assume, it shouldnt be used that way.Best regard and greetings, Gerhard Link to comment Share on other sites More sharing options...
Sherzod Posted June 24, 2017 Share Posted June 24, 2017 Hi, Can you try for now with this fine example ?: http://forums.unigui.com/index.php?/topic/5300-lines-game-ext-and-touch-version/ Best regards, Link to comment Share on other sites More sharing options...
gerhardhziegler Posted June 24, 2017 Author Share Posted June 24, 2017 Thanks a lot. Its really a fine example and I hope, I understood the usage of the frames! Link to comment Share on other sites More sharing options...
gerhardhziegler Posted June 25, 2017 Author Share Posted June 25, 2017 Hmmm.. doesnt work. I used a frame now, containing the Canvas.Anyway on opening the mobile form, that is containing the frame, the error "Ext.Form.Canvas is not a constructor" occured.So did I understand anything wrong? I am not completely sure I understood the concept behind the demo. I did include the JS library, then the constructor error vanished.

gerhardhziegler Posted June 25, 2017 Author Share Posted June 25, 2017 Update 19:20 MEZ:Could use the LinesGame now for drawing, but its simple not performant enough. Though its server side bitmap manipulation, the mouse events are processed there in LinesTools.MoveDownEvent. I simply dont get how to use the "internal" js functions from unimcanvas-min.js for the usage of drawing while mousemove. Link to comment Share on other sites More sharing options...
RDybuco Posted October 31, 2018 Share Posted October 31, 2018 gerhardhziegler, Have you found the solution to the signature problem? I'm stuck on this same situation trying to capture user signatures from touch devices. Any Help? Link to comment Share on other sites More sharing options...
