Std DlgParameter/de

Beschreibung
Der Befehl Std ParameterDialog öffnet den Parametereditor. Im Parametereditor können die Parameter eingesehen und bei Bedarf gelöscht, hinzugefügt und geändert werden, die das Verhalten von FreeCAD und seinen Arbeitsbereichen steuern. Die Parameter werden in einer Datei namens gespeichert, deren Speicherort vom benutzten Betriebssystem abhängt.

Mit dem Parametereditor zu arbeiten erfordert etwas Erfahrung. Für die üblichen Parameter kann man auch den benutzerfreundlicheren Voreinstellungseditor verwenden.



Anwendung

 * 1) Auswahl des Menüeintrags.
 * 2) Das Dialogfeld des Parametereditors öffnet sich. Siehe Optionen für weitere Informationen.
 * 3) Optional drückt man die Schaltfläche, um die Datei  sofort zu aktualisieren. Dies ist nicht zwingend erforderlich, da FreeCAD die Datei automatisch aktualisiert, wenn die Anwendung geschlossen wird.
 * 4) Schaltfläche  drücken um den Parametereditor zu schließen.

Left panel
The left panel shows a tree with parameter groups and sub-groups.

The following options are available in the panel's context menu:

Expand/Collapse

 * 1) If a selected group has one or more sub-groups it can be expanded or collapsed by choosing this option from the context menu. But you can also expand and collapse the tree in the usual manner.

Add sub-group

 * 1) Select a group.
 * 2) Select the  option from the context menu.
 * 3) Enter a name for the new sub-group in the dialog box that opens.
 * 4) Press the  button.

Remove group

 * 1) Select a group.
 * 2) Select the  option from the context menu.
 * 3) Press the  button in the dialog box that opens to confirm you want to remove the group (including all its sub-groups, and all parameters in the group and its sub-groups).

Rename group

 * 1) Select a group.
 * 2) Select the  option from the context menu.
 * 3) Enter a new name.
 * 4) A group can also be renamed by double-clicking it.

Export parameter

 * 2) Select the  option from the context menu.
 * 3) Enter a filename in the dialog box.

 * 2) Select the  option from the context menu.
 * 3) Select a *.FCParam file in the dialog box.
 * 4) Press the  button.

Right panel
The right panel shows the parameters in the group selected in the left panel. If this group only contains sub-groups the right panel will be empty.

The following options are available in the panel's context menu:

Change value

 * 1) Select a parameter.
 * 2) Select the  option from the context menu.
 * 3) Enter a new value in the dialog box that opens.
 * 4) Press the  button.
 * 5) A parameter's value can also be changed by double-clicking its 'Type' or 'Value' field.

Remove key

 * 1) Select a parameter.
 * 2) Select the  option from the context menu.

Rename key

 * 1) Select a parameter.
 * 2) Select the  option from the context menu.
 * 3) Enter a new name.
 * 4) A parameter can also be renamed by double-clicking its 'Name' field.

New string item

 * 1) Select the  or  option from the context menu.
 * 2) Enter a name in the dialog box that opens.
 * 3) Press the  button.
 * 4) Enter a value in the next dialog box.
 * 5) Press the  button.

New float item

 * 1) Select the  or  option from the context menu.
 * 2) The next steps are similar to those for a New string item

New integer item

 * 1) Select the  or  option from the context menu.
 * 2) The next steps are similar to those for a New string item

New unsigned item

 * 1) Select the  or  option from the context menu.
 * 2) The next steps are similar to those for a New string item

New Boolean item

 * 1) Select the  or  option from the context menu.
 * 2) The next steps are similar to those for a New string item

Sorting
By default the groups in each tree level in the left panel are sorted alphabetically, and the parameters in the right panel are sorted alphabetically as well. But the order in each panel can be reversed by clicking the 'Group' or 'Name' header respectively.

Quick search
Typing a (partial) string in this input box will fully expand the tree in the left panel and highlight all groups with names that match the entered value. If no matches are found the background of the input box will turn red.

Find

 * 1) In the left panel select the group where you want to start your search. The search direction is down. The search is not restricted to the group and its sub-groups, but rather the selected group and everything below it in the tree will be searched.
 * 2) Press the  button.
 * 3) Enter a string in the Find what input box. The search is case-insensitive.
 * 4) Check one or more of the,  and  checkboxes. Note that only string values will be searched.
 * 5) Optionally (un)check the  checkbox.
 * 6) Press the  button to select the first group with a match. Matching parameters are not individually highlighted. Optionally repeat this until no further matches can be found.
 * 7) It is possible to start a new search without closing the dialog box. Again selecting the group from which to start searching is then usually required.
 * 8) Use the  button to close the dialog box.

Scripting
FreeCAD Scripting Basics.

Preferences can be accessed from Python scripts using their corresponding path in the Parameter Editor. For example, the preference appears in  and has type. It can therefore be accessed in Python using the following code:

Finding which parameter is used to store which option from the Preferences editor can require searching a bit, but the Parameter Editor offers a search facility, which should help.

It is likely a bad idea to modify the preferences of other parts of FreeCAD unless doing so at the user's request. The setter can however be used to set parameters for your own workbench, and the getter can be used to obey existing parameters.
