Hi,
Just an update for some fun I’ve been having with @BenRobinson_HB’s work on Winforms and python.
Winforms Example.dyn (19.9 KB)
I wanted tp be able to run a single Python script and include a dialogue…
Usually you would make an XAML code to define where everything goes and how it works, then you’d have a separate C# code to do all the heavy lifting.
A different option is to still use the XAML, but load it to Python using PresentationFramework in presentationframework, seemingly some limitations, but easier to work with.
I think the biggest problem for this method is that you can’t pass input updates from window to window, I suspect this is a Dynamo limitation, more than a Python limitation.
Ben’s work is found here: How to Build Graphical User Interface Nodes for Dynamo Using Python | Autodesk University
I left in the dropdown he made, I’ve also done some other things… Checkboxes, Text input &Text input warning… This is fun because there is no WInform just for number input, I tried to make a Dynamic warning which ran when you put in a character which failed a reg-ex check, but it wouldn’t dynamically update when you removed the illegal character.
There’re are lots of lines of code, but they are relatively simple… As Ben noted, there is very little Python documentation on this, so hopefully it is useful to expand it a bit.
I have kept the code as readable as possible. All comments welcomed!
You will need to change the paths to your own logos / bitmaps, otherwise it should just run. I tried to get bitmaps from a web address but I couldn’t get that working without saving locally (which seemed a bit rude)…
