[Paraview] Custom filter: exposed properties of a Calculator filter

[Jean-Michel Lucas]

Cory,

 

Thank you for your answer, you understood my problem perfectly. I noticed the problem is somewhat similar when trying to incorporate a Python calculator to a custom filter and exposing the property name (in this case, the name remains 'Expression' no matter what you specify when creating the filter). 

 

The reason I asked this question is that I need to design a filter that asks some input from the user before performing some calculations. The way I used to do this was by creating a calculator with the name of the quantity the user has to give.

 

However, I'm afraid I'm not sufficiently skilled in C++ to delve into custom widgets. I'll try to find a workaround.

 

Thanks again,

Jean-Michel

Jean-Michel,

 

Thank you for clarifying, I think I understand now. So you see the calculator buttons and text field for entering the expression? And you want the name of the property to appear in the label?

 

For this property, a custom widget is used in the Properties panel that does not display the property name. Hence, the property name does not show up. I see that in 3.14 the Function is displayed with a simple text field - you don't get the calculator buttons.

 

We'd have to change the custom widget to display the property name. This would be a relatively simple change that I could walk you through if you'd like to contribute to the ParaView source code.

 

Let me know if you are interested.

 

Thanks,

Cory

Hi Cory,

 

Thank you for your answer.

 

I did remember to click the + sign, and in fact the property shows fine when playing the filter later on. Only the property name, which you can choose when designing the filter, doesn't appear in ParaView 4.3. If I open the same custom filter in ParaView 3.12, the name does show up.

 

Best,

Jean-Michel

Jean-Michel,

 

I am not able to reproduce what you are reporting with 4.3.1 or 4.4.

 

Did you remember to click the + sign when adding the property? The first time I tried I forgot to do that, and the Function property was not exposed in my custom filter. When I did add the property, it was exposed.

 

HTH,

Cory

Hi,

 

I am trying to create a Custom Filter in ParaView 4.3.1.

 

I am having trouble with the exposed properties of a Calculator filter: when defining the properties for my custom filter, I am selecting the "Function" property and setting the property name for this Calculator. However, when using the custom filter, this property name does not appear in the Properties panel of the Object Inspector. Is this a known bug or is there something I'm missing ?

 

Also, is it possible to hide the calculator buttons and only leave the blank field ? This was the default behavior in (at least) ParaView 3.12.0.

 

Thank you for your help.

 

Jean-Michel
