Parameter with a Python list¶
The value of the PythonPart parameter can be created as a Python list object of the used value type.
Syntax¶
For the definition of the list in the <Value> tag a general Python statement for list creation can be used
[]
[1000.,1200.,1400.,1600.,1800.]
[1000.] * 5
[[0 for x in range(3)] for y in range(5)]
…
By adding the list parameter to a Row and setting the value of the row to 1, the entire row can be used for the controls
Optional tags¶
If the length of the list is to be dynamic, the following tag must be added
<Dimensions>CubeCount</Dimensions>
The name assigned to <Dimensions> must be the name of an existing Integer parameter, an integer constant or a formula created by parameter names like
<Dimensions>CubeCount + 1</Dimensions>
Depending on the value of this parameter, the list is lengthened or shortened.
The list can be a one-dimensional or two-dimensional. In case of a two-dimensional list the <Dimensions> tag must consist of two entries like
<Dimensions>CubeCount,CoordDimension3D + 2</Dimensions>
The result in the property palette looks like
Each row of the list in the property palette is tagged with a row index. By default this index starts at 0. The starting index can be changed by adding the tag
<ValueListStartRow>1</ValueListStartRow>
with the defined start index. If the value is set to -1, no index is displayed
If only one row of the list is to be displayed in the property palette, the tag
<ValueIndexName>VisibleRowIndex</ValueIndexName>
must be added. The name assigned to <ValueIndexName> must be the name of an existing Integer or IntegerComboBox parameter. The row index starts from 1.
Additionally, all optional tags from the defined <ValueType> can be used. Advanced possibilities for the enable and visible state of a list row can be found here Enable and visible options.
Access to list row values¶
The special keyword $list_row allows access to values from a row in the tags <Visible>, <Enable>, <MinValue> and <MaxValue>.
Example¶
The implementation of the list value type is described in the example ListValues, which is located in
