godwhoa / gowut Goto Github PK

Feature request:
1. add canvas component that supports rendering image or svg.

To learn Go, I am porting a python utility based on matplotlib to Go. 
Matplotlib provides browser-based rendering backend using a canvas element.  
http://matplotlib.org/users/whats_new.html#backends And, I was attracted to 
Gowut as a way to create the UI with Go.

The issue I encountered with reloading the current gowut image component within 
a gowut page is that there was obvious blinking as the image was removed and 
reloaded.  Drawing to a canvas element could avoid this.

Would adding minimal support for a canvas component to Gowut that allows 
drawing images be welcome?

If you do not have time to make this change, but think it would be a good idea, 
can you recommend how to approach it within the Gowut framework?  I'd be happy 
to give it a "go".

Thank you.

What steps will reproduce the problem?

b := gwu.NewButton("QUIT")
b.AddEHandlerFunc(func(e gwu.Event) {
  panic("try to show goroutines and quit")
}, gwu.ETYPE_CLICK)

What is the expected output? What do you see instead?
I wish there is a method to let me quit program when button pressed

What version of the product are you using? On what operating system?

Less a bug than a feature request.
If instead of choosing between "text" and "password" at render time these were 
set at "type" attributes (c.SetAttr("type", "text"), for example), then the 
user could over-ride the text box to, say "number".  It also shrinks the code 
quite a bit.
I don't have a full implementation of this change, but I have tested it and 
could flesh it out to submit a patch if you approve of the direction.
