Define filter¶

Use this dialog to define filters for line, point, text, polygon, and triangle net objects.

Where do I find the dialog?¶

The dialog is opened from the Filter tab under the Define button in application layer properties or directly from the context menu in the object list under Define active filter (D)...

Using the dialog¶

You can create a filter based on one or more attributes (fields).

Each attribute has a list with one or more values used for matching.

You can choose between three methods for matching:

Equal
From-To
Pattern

For patterns you can use wildcards:

* is used as a wildcard for "zero or more characters"
K* can for example match KUM, K123, etc.
? is used for "one arbitrary character"
K? can for example match KU or K1, but not KUM

For each list, you must choose whether the values should be included (include these values) or excluded (exclude these values).

Procedure

Add attribute (field) you want to filter on.
Select method, for example Equal, and enter the desired value - or select from the dropdown menu (if you check Show only used, only values that exist in the layer will be shown)
Click Add and specify whether the value should be included or excluded.
Repeat steps 2-3 to add more values for the same attribute.
Repeat steps 1-3 to add more attributes to the filter.

Using filter in object list¶

For quick access to the dialog, you can also find the menu option directly in the object list. You can turn the filter on/off with the shortcut key [F]. Available shortcut keys are described below.

Shortcut keys¶

[D]: Open dialog for Define filter...

[F]: Turn defined filter on/off (if a filter is turned on, this will be marked with an F in the column header for the tab)

[V]: Turn display of objects on/off (means you can also turn on/off display of filtered data)
