Hi,
I’ve been trying to create a button that begins a task to connect two
blender sessions together on two separate machines, so far I have been able to
get the backend to work, but I would like to change the appearance of the
button to match the state my task is in. Its fairly basic, when the user
presses the button it changes to a pending state, then a connected state if the
connection works, or back to the ready state if the connection fails (there may
also be a report to the console or info section in this case, separate issue
thought).
I use a simple piece of code to do this in a custom panel class
def draw(self, context):
button_operator = operators[client.status]
button_icon = icons[client.status]
button_text = text[client.status]
layout.operator( button_operator, button_icon, button_text)
depending on the value of client.state, a different set of button operator,
icon and text is displays. This kind of works, but the issue I am having is
that the user has to mouse over the button in order to make the icon and text
change. I also suspect this is the same for the operator, but since you have to
mouse over to click the button, i never trigger the wrong operator.
I have been searching for why the button only re-draws on mouseover and not
when the values of button_operator, icon and text change, but I haven’t found
anything to suggest why.
So, I’d like to know, how can I create a button that does redraw when these
properties change? What actually causes the operator to redraw other than a
mouse over? I have experimented with layout.prop, this will change when the
property changes and I don’t have to mouse over it, but I would rather have a
button than a property since the button is used to connect, cancel and
disconnect.
Thanks!
James
