<div dir="ltr">good news:
<div>programmable source/filter has a property called
Parameters that lets you pass in arbitrary values.
<div>See an example of its use in the standard
benchmark here: <a

</div>
<div>bad news:</div>
<div>To my knowledge we have never exposed that
property to the end user in the Qt parts of the GUI.
If someone can provide a good example of a qt plugin
or otherwise that exposes parameters to the end
user, please advise on this thread.</div>

<div>You can do what is described in this blog post to
package your programmable source nicely with modifiable
attributes. See <a

for details (it is 5 years old, but still applicable to
ParaView 5.5).</div>

<div bgcolor="#FFFFFF"> Hi all,
<p>I have made a small Programmable Filter
that converts my input data. Now I have
one parameter (resolution) that I would
like to be modifiable by the user. My
script currently looks as follows:</p>
<pre style="margin:0px;text-indent:0px"><span style="font-family:monospace">resolution = 20
val </span><span style="font-family:monospace;color:rgb(102,102,102)">=</span><span style="font-family:monospace"> {</span><span style="font-family:monospace;color:rgb(186,33,33)">'resolution'</span><span style="font-family:monospace">: resolution, </span><span style="font-family:monospace;color:rgb(186,33,33)">'self'</span><span style="font-family:monospace">: </span><span style="font-family:monospace;color:rgb(0,128,0)">self</span><span style="font-family:monospace">}</span></pre>
<pre style="margin:0px 0px 12px;text-indent:0px"><span style="font-family:monospace;color:rgb(0,128,0)">execfile</span><span style="font-family:monospace">(</span><span style="font-family:monospace;color:rgb(186,33,33)">'/path/to/filter.py'</span><span style="font-family:monospace">, val)
</span><span style="font-family:monospace"></span>
</pre>
Ideally I want my users to not have to
replace the 20 by whatever value they
desire, but instead make a Custom Filter
with either a text input field or a slider
that will pipe its value to the Programmable
Filter. Is something like this possible at
all?<br>
<br>
Thanks in advance for your help,<br>
Arno<br>
