I was considering create a "master" widget as a child of the main window and sync it to the widget drawn on the canvas, but that seems like a lot of trouble. Is there some other workaround?<br></div></div></blockquote><div><br></div><div>That is true, but tkwidgets are all about using Tk widgets in Pd as easily as possible. If the Tk widget is not drawn to the screen, then the Tk widget is not involved. What is the problem in particular? You want to change its state while its not visible? I think the idea there is to have the state stored in the standard struct as a dump from the Tk widget. So when its not visible, store the state-changes, when it becomes visible, dump the state to the Tk widget.</div><br><blockquote type="cite"><div><div style="color:rgb(0, 0, 0);background-color:rgb(255, 255, 255);font-family:times, serif;font-size:12pt;">Another thing: to get "Pd-style" interaction, bind $canvas <<EditMode>> to a proc that sets -state to disabled for all tkwidgets in that $canvas when editmode == 1. That way you don't end up triggering the widget when you want to edit it.<br></div></div></blockquote><div><br></div><div>Yeah, tkwidgets was mostly written about the same time as I starting the pd-gui-rewrite. As I rewrote a lot of pd-gui, I realized I should wait on tkwidgets since I could fix a lot of things in pd-gui first. The <<EditMode>> message is one example. tkwdigets is not complete yet, so this is not fully in there. I think the [entry] in github does this kind of stuff.</div><div><br></div><div>.hc</div><br><blockquote type="cite"><div><div style="color:rgb(0, 0, 0);background-color:rgb(255, 255, 255);font-family:times, serif;font-size:12pt;"><div><blockquote style="border-left-width:2px;border-left-style:solid;border-left-color:rgb(16, 16, 255);margin-left:5px;padding-left:5px;"><div style="font-family:times new roman, new york, times, serif;font-size:12pt;"><div style="font-family:times new roman, new york, times, serif;font-size:12pt;"><font face="Arial" size="2"> Hans-Christoph Steiner <<a rel="nofollow" ymailto="mailto:hans@at.or.at" target="_blank" href="mailto:hans@at.or.at">hans@at.or.at</a>><br><b><span style="font-weight:bold;">To:</span></b> Jonathan Wilkes <<a rel="nofollow" ymailto="mailto:jancsika@yahoo.com" target="_blank" href="mailto:jancsika@yahoo.com">jancsika@yahoo.com</a>><br><b><span style="font-weight:bold;">Cc:</span></b> pd-dev List <<a rel="nofollow" ymailto="mailto:pd-dev@iem.at" target="_blank" href="mailto:pd-dev@iem.at">pd-dev@iem.at</a>><br><b><span style="font-weight:bold;">Sent:</span></b> Wednesday, August 17, 2011 2:54 PM<br><b><span style="font-weight:bold;">Subject:</span></b> Re: tkwidgets<br></font><br><div id="yiv1252287210"><div><br></div><div>Hey Jonathan,</div><div><br></div><div>I'm cc'ing pd-dev since this is a topic that could interest others and others could contribute to. I've started a private git branch of tkwidgets that I intent to push once I get somewhere with it. The idea is to try out a new idea for how GUI objects can work. Basically, I think I can make it so that Tcl handles more of the interaction with the user, minimizing on pd-gui <--> pd communications, and making it easier to write GUI objects. Its not trivial to do, but should be doable.</div><div><br></div><div>.hc</div><div><br></div><br><div><div>On Aug 17, 2011, at 12:26 PM, Jonathan Wilkes wrote:</div><br class="yiv1252287210Apple-interchange-newline"><blockquote type="cite"><div><div style="color:#000;background-color:#fff;font-family:times new roman, new york, times, serif;font-size:12pt;"><div><span>Never mind, I see it now inside canvas_vis... too bad canvas' "window" subcommand doesn't have something like pack's "-in" option...</span></div><div><br><span></span></div><div><span>But I guess I could make a toplevel checkbutton widget and just manually clone it.<br></span></div><div><br><span></span></div><div><span>-Jonathan<br></span></div><div><br><blockquote style="border-left:2px solid rgb(16, 16, 255);margin-left:5px;padding-left:5px;"><div style="font-family:times new roman, new york, times, serif;font-size:12pt;"><div style="font-family:times new roman, new york, times, serif;font-size:12pt;"><font face="Arial" size="2"><hr size="1"><b><span style="font-weight:bold;">From:</span></b> Jonathan Wilkes <<a rel="nofollow" ymailto="mailto:jancsika@yahoo.com" target="_blank" href="mailto:jancsika@yahoo.com">jancsika@yahoo.com</a>><br><b><span style="font-weight:bold;">To:</span></b> Hans- Christoph Steiner <<a rel="nofollow" ymailto="mailto:hans@at.or.at" target="_blank" href="mailto:hans@at.or.at">hans@at.or.at</a>><br><b><span style="font-weight:bold;">Sent:</span></b> Wednesday, August 17, 2011 3:14 AM<br><b><span style="font-weight:bold;">Subject:</span></b> tkwidgets<br></font><br><div id="yiv1252287210"><div style="color:#000;background-color:#fff;font-family:times new roman, new york, times, serif;font-size:12pt;"><div>Hi Hans,</div><div> Do I have it right that your tkwidgets get destroyed when the containing patch is vis'd 0?
